You

In touchdesigner I’m using this chop execute to turn off certain base containers. I want to add other containers to the list of being turned on and off, how should I add these?

ChatGPT

To add more containers to your CHOP Execute script in TouchDesigner, you’ll need to extend the existing script to include the new containers. Here’s a step-by-step guide on how to modify your CHOP Execute DAT to include additional containers for turning them on and off:

1. Open your CHOP Execute DAT: This is the script that responds to changes in the CHOP channels.

2. Identify your existing script: Locate the part of the script where you are turning off the containers. It might look something like this:

   def offToOn(channel, sampleIndex, val, prev):
       if val == 1:
           op('container1').par.display = True
           op('container1').par.enable = True
       return
   
   def onToOff(channel, sampleIndex, val, prev):
       if val == 0:
           op('container1').par.display = False
           op('container1').par.enable = False
       return

3. Add new containers to the script: To turn additional containers on and off, you will need to add similar lines for each new container within the offToOn and onToOff functions. For example, if you want to add container2 and container3, your script will be updated as follows:

   def offToOn(channel, sampleIndex, val, prev):
       if val == 1:
           op('container1').par.display = True
           op('container1').par.enable = True
           op('container2').par.display = True
           op('container2').par.enable = True
           op('container3').par.display = True
           op('container3').par.enable = True
       return
   
   def onToOff(channel, sampleIndex, val, prev):
       if val == 0:
           op('container1').par.display = False
           op('container1').par.enable = False
           op('container2').par.display = False
           op('container2').par.enable = False
           op('container3').par.display = False
           op('container3').par.enable = False
       return

4. Save and test your script: After making these changes, save your script and test it by triggering the CHOP channels that control the on and off states. Ensure that all specified containers are responding correctly.

By following these steps, you can add as many containers as needed to the script, allowing them to be turned on and off in response to the CHOP Execute triggers.

You

This is the script:

me - this DAT

channel - the Channel object which has changed

sampleIndex - the index of the changed sample

val - the numeric value of the changed sample

prev - the previous sample value

Make sure the corresponding toggle is enabled in the CHOP Execute DAT.

def onOffToOn(channel, sampleIndex, val, prev): return

def whileOn(channel, sampleIndex, val, prev): return

def onOnToOff(channel, sampleIndex, val, prev): return

def whileOff(channel, sampleIndex, val, prev): return

def onValueChange(channel, sampleIndex, val, prev): threshold = 15 container_paths = { ‘angel’: [‘/project1/base1/ANGEL_FX’], ‘hero’: [‘/project1/base1/HERO_FX’], ‘feminist’: [‘/project1/base1/FEMINIST_FX’], ‘rebel’: [‘/project1/base1/REBEL_FX’] }

# Debugging: print the channel name and value
print(f"Channel: {channel.name}, Value: {val}")

# Check if the channel name exists in the dictionary
if channel.name in container_paths:
    for path in container_paths[channel.name]:
        container = op(path)
        # Debugging: print the path and if the container was found
        print(f"Path: {path}, Container found: {container is not None}")
        if container:
            if val < threshold:
                print(f"Stopping cooking for: {path}")
                container.allowCooking = False
            else:
                print(f"Starting cooking for: {path}")
                container.allowCooking = True
else:
    print(f"Channel {channel.name} not in container_paths")

return

ChatGPT

To add more containers to the script, you can extend the container_paths dictionary with the new container names and their respective paths. This way, the script will check and control the cooking status of the additional containers as well.

Here’s your updated script with additional containers:

# me - this DAT
# channel - the Channel object which has changed
# sampleIndex - the index of the changed sample
# val - the numeric value of the changed sample
# prev - the previous sample value
# Make sure the corresponding toggle is enabled in the CHOP Execute DAT.

def onOffToOn(channel, sampleIndex, val, prev):
    return

def whileOn(channel, sampleIndex, val, prev):
    return

def onOnToOff(channel, sampleIndex, val, prev):
    return

def whileOff(channel, sampleIndex, val, prev):
    return

def onValueChange(channel, sampleIndex, val, prev):
    threshold = 15
    container_paths = {
        'angel': ['/project1/base1/ANGEL_FX'],
        'hero': ['/project1/base1/HERO_FX'],
        'feminist': ['/project1/base1/FEMINIST_FX'],
        'rebel': ['/project1/base1/REBEL_FX'],
        # Add new containers here
        'warrior': ['/project1/base1/WARRIOR_FX'],
        'mage': ['/project1/base1/MAGE_FX'],
        'rogue': ['/project1/base1/ROGUE_FX']
    }

    # Debugging: print the channel name and value
    print(f"Channel: {channel.name}, Value: {val}")

    # Check if the channel name exists in the dictionary
    if channel.name in container_paths:
        for path in container_paths[channel.name]:
            container = op(path)
            # Debugging: print the path and if the container was found
            print(f"Path: {path}, Container found: {container is not None}")
            if container:
                if val < threshold:
                    print(f"Stopping cooking for: {path}")
                    container.allowCooking = False
                else:
                    print(f"Starting cooking for: {path}")
                    container.allowCooking = True
    else:
        print(f"Channel {channel.name} not in container_paths")

    return

Explanation:

1. Add New Containers: I added warrior, mage, and rogue to the container_paths dictionary with their respective paths.
2. Loop Through Paths: The script already loops through the paths for each channel, so any new containers added will be handled automatically by this logic.

You can extend the container_paths dictionary with as many containers as needed. Just make sure the paths are correct, and the channel names match those coming from your CHOPs. This way, the script will manage the allowCooking property for all specified containers based on the channel values.

I want to add more containers to the existing categories

ChatGPT

To add more containers to the existing categories within the container_paths dictionary, you simply need to extend the lists associated with each category key. Here’s your updated script with additional containers added to the existing categories:

# me - this DAT
# channel - the Channel object which has changed
# sampleIndex - the index of the changed sample
# val - the numeric value of the changed sample
# prev - the previous sample value
# Make sure the corresponding toggle is enabled in the CHOP Execute DAT.

def onOffToOn(channel, sampleIndex, val, prev):
    return

def whileOn(channel, sampleIndex, val, prev):
    return

def onOnToOff(channel, sampleIndex, val, prev):
    return

def whileOff(channel, sampleIndex, val, prev):
    return

def onValueChange(channel, sampleIndex, val, prev):
    threshold = 15
    container_paths = {
        'angel': ['/project1/base1/ANGEL_FX', '/project1/base2/ANGEL_FX2'],
        'hero': ['/project1/base1/HERO_FX', '/project1/base2/HERO_FX2'],
        'feminist': ['/project1/base1/FEMINIST_FX', '/project1/base2/FEMINIST_FX2'],
        'rebel': ['/project1/base1/REBEL_FX', '/project1/base2/REBEL_FX2']
    }

    # Debugging: print the channel name and value
    print(f"Channel: {channel.name}, Value: {val}")

    # Check if the channel name exists in the dictionary
    if channel.name in container_paths:
        for path in container_paths[channel.name]:
            container = op(path)
            # Debugging: print the path and if the container was found
            print(f"Path: {path}, Container found: {container is not None}")
            if container:
                if val < threshold:
                    print(f"Stopping cooking for: {path}")
                    container.allowCooking = False
                else:
                    print(f"Starting cooking for: {path}")
                    container.allowCooking = True
    else:
        print(f"Channel {channel.name} not in container_paths")

    return

Explanation:

1. Extend Lists: For each key in the container_paths dictionary, I added additional container paths. For example, 'angel' now includes both '/project1/base1/ANGEL_FX' and '/project1/base2/ANGEL_FX2'.
2. Loop Through Paths: The existing logic already loops through all paths associated with each channel, so it will handle the additional containers automatically.

You can continue to add as many paths as needed within each category list. Just ensure the paths are accurate and reflect the locations of your containers within the TouchDesigner project.

I now need to create a new script which monitors a switch top ‘switch2’ and only when the switch has index 5,6,7 or 8 do we cook the coressponding containers connected to those indexes

ChatGPT

To create a new script that monitors a switch TOP (switch2) and enables cooking for corresponding containers when the switch index is 5, 6, 7, or 8, you can follow these steps:

1. Create a new CHOP Execute DAT: This will monitor the switch index.
2. Write a script that checks the switch index and enables/disables cooking for the corresponding containers.

Here is a step-by-step guide and the script to accomplish this:

Step 1: Create a CHOP Execute DAT

1. Add a CHOP Execute DAT to your project.
2. Connect it to the switch index CHOP: Ensure it is connected to the CHOP that outputs the index of switch2.

Step 2: Write the Script

Edit the CHOP Execute DAT script to monitor the switch index and control the cooking of the corresponding containers.

Here’s an example script:

# me - this DAT
# channel - the Channel object which has changed
# sampleIndex - the index of the changed sample
# val - the numeric value of the changed sample
# prev - the previous sample value
# Make sure the corresponding toggle is enabled in the CHOP Execute DAT.

def onOffToOn(channel, sampleIndex, val, prev):
    return

def whileOn(channel, sampleIndex, val, prev):
    return

def onOnToOff(channel, sampleIndex, val, prev):
    return

def whileOff(channel, sampleIndex, val, prev):
    return

def onValueChange(channel, sampleIndex, val, prev):
    switch_index = int(val)
    container_paths = {
        5: ['/project1/base1/CONTAINER_5'],
        6: ['/project1/base1/CONTAINER_6'],
        7: ['/project1/base1/CONTAINER_7'],
        8: ['/project1/base1/CONTAINER_8']
    }

    # Turn off all containers initially
    for paths in container_paths.values():
        for path in paths:
            container = op(path)
            if container:
                container.allowCooking = False

    # Check if the switch index is 5, 6, 7, or 8 and enable cooking for corresponding containers
    if switch_index in container_paths:
        for path in container_paths[switch_index]:
            container = op(path)
            if container:
                container.allowCooking = True
                print(f"Starting cooking for: {path}")
    else:
        print(f"Switch index {switch_index} is not in the range of 5, 6, 7, or 8")

    return

Explanation:

1. Monitor Switch Index: The onValueChange function monitors the value of the switch index.
2. Container Paths: A dictionary container_paths maps each relevant switch index to its corresponding container path(s).
3. Disable Cooking for All Containers: Initially, disable cooking for all containers.
4. Enable Cooking for Relevant Containers: If the switch index is 5, 6, 7, or 8, enable cooking for the corresponding containers.
5. Debugging: Print statements help with debugging to confirm which paths are being activated or deactivated.

This script should be placed in the CHOP Execute DAT connected to the switch index CHOP. Ensure the toggle for Value Change is enabled in the CHOP Execute DAT to trigger the onValueChange function whenever the switch index changes.

You

rather than a chop execute can we just use a script dat?

ChatGPT

Certainly! You can use a Script DAT to achieve the same functionality. In a Script DAT, you can write a script that continuously monitors the switch index and updates the cooking status of the containers accordingly. Here’s how you can do it:

Step 1: Create a Script DAT

1. Add a Script DAT to your project.
2. Ensure the Script DAT runs periodically: You can use a Timer CHOP or a similar mechanism to trigger the script execution periodically.

Step 2: Write the Script

Here’s an example script to be placed in the Script DAT:

def onRun(scriptOp):
    # Get the switch index from switch2
    switch_index = int(op('switch2').par.index)

    container_paths = {
        5: ['/project1/base1/CONTAINER_5'],
        6: ['/project1/base1/CONTAINER_6'],
        7: ['/project1/base1/CONTAINER_7'],
        8: ['/project1/base1/CONTAINER_8']
    }

    # Turn off all containers initially
    for paths in container_paths.values():
        for path in paths:
            container = op(path)
            if container:
                container.allowCooking = False

    # Check if the switch index is 5, 6, 7, or 8 and enable cooking for corresponding containers
    if switch_index in container_paths:
        for path in container_paths[switch_index]:
            container = op(path)
            if container:
                container.allowCooking = True
                print(f"Starting cooking for: {path}")
    else:
        print(f"Switch index {switch_index} is not in the range of 5, 6, 7, or 8")

    return

# Call the function to run it initially
onRun(None)

Explanation:

1. Define the onRun Function: This function contains the logic to monitor the switch index and update the container cooking status.
2. Get the Switch Index: The script reads the current switch index from the switch2 TOP using op('switch2').par.index.
3. Container Paths: A dictionary container_paths maps each relevant switch index to its corresponding container path(s).
4. Disable Cooking for All Containers: Initially, disable cooking for all containers.
5. Enable Cooking for Relevant Containers: If the switch index is 5, 6, 7, or 8, enable cooking for the corresponding containers.
6. Debugging: Print statements help with debugging to confirm which paths are being activated or deactivated.
7. Initial Run: The function is called initially to ensure the script runs when you first set it up.

Triggering the Script Periodically

To run the script periodically, you can use a Timer CHOP or another mechanism:

1. Add a Timer CHOP to your project.
2. Set the Timer CHOP to trigger at regular intervals (e.g., every second).
3. Connect the Timer CHOP to a CHOP Execute DAT.
4. In the CHOP Execute DAT: Call the onRun function from the Script DAT.

Here’s how the CHOP Execute DAT script might look:

def onValueChange(channel, sampleIndex, val, prev):
    # Run the Script DAT's function
    op('script_dat_name').run()
    return

Replace 'script_dat_name' with the actual name of your Script DAT.

This setup will ensure that your Script DAT runs periodically, checking the switch index and updating the container cooking status as needed.

Infact it can stay a chop execute and I’ll monitor an osc in, when we detect a value change in the osc in we can check the switch index and cook/uncook as necessary

ChatGPT

Great! Keeping it as a CHOP Execute DAT and monitoring an OSC In channel for value changes is a good approach. Here’s how you can set it up:

Step 1: Configure the OSC In CHOP

1. Add an OSC In CHOP: Set it up to receive the necessary OSC messages.
2. Ensure the OSC In CHOP is outputting the correct channel: This channel will trigger the value change detection in the CHOP Execute DAT.

Step 2: Write the Script in the CHOP Execute DAT

Here’s the updated script for the CHOP Execute DAT that will monitor the OSC In channel for value changes, then check the switch index, and adjust the cooking status of the containers accordingly:

# me - this DAT
# channel - the Channel object which has changed
# sampleIndex - the index of the changed sample
# val - the numeric value of the changed sample
# prev - the previous sample value
# Make sure the corresponding toggle is enabled in the CHOP Execute DAT.

    return

def checkSwitchIndex():
    # Get the switch index from switch2
    switch_index = int(op('switch2').par.index)

    container_paths = {
        5: ['/project1/base1/CONTAINER_5'],
        6: ['/project1/base1/CONTAINER_6'],
        7: ['/project1/base1/CONTAINER_7'],
        8: ['/project1/base1/CONTAINER_8']
    }

    # Turn off all containers initially
    for paths in container_paths.values():
        for path in paths:
            container = op(path)
            if container:
                container.allowCooking = False

    # Check if the switch index is 5, 6, 7, or 8 and enable cooking for corresponding containers
    if switch_index in container_paths:
        for path in container_paths[switch_index]:
            container = op(path)
            if container:
                container.allowCooking = True
                print(f"Starting cooking for: {path}")
    else:
        print(f"Switch index {switch_index} is not in the range of 5, 6, 7, or 8")

    return

Explanation:

1. Define checkSwitchIndex Function: This function contains the logic to check the switch index and update the cooking status of the containers.
2. Get the Switch Index: The script reads the current switch index from the switch2 TOP using op('switch2').par.index.
3. Container Paths: A dictionary container_paths maps each relevant switch index to its corresponding container path(s).
4. Disable Cooking for All Containers: Initially, disable cooking for all containers.
5. Enable Cooking for Relevant Containers: If the switch index is 5, 6, 7, or 8, enable cooking for the corresponding containers.
6. Debugging: Print statements help with debugging to confirm which paths are being activated or deactivated.
7. Call checkSwitchIndex: This function is called from all the event functions (onOffToOn, whileOn, onOnToOff, whileOff, and onValueChange).

Enabling Toggles

1. Enable the appropriate toggles in the CHOP Execute DAT to ensure it reacts to the value changes. You’ll want to enable the toggle for Value Change at least.

This setup will ensure that your CHOP Execute DAT script monitors the OSC In channel for value changes, checks the switch index, and updates the cooking status of the corresponding containers as necessary.

You

Add these paths:

5: [‘/project1/base1/TYPOGRAPHY_V2/Text_Rip_OUT’], 6: [‘/project1/base1/TYPOGRAPHY_V2/arranging_text’], 7: [‘/project1/base1/TYPOGRAPHY_V2/radial_tex’], 8: [‘/project1/base1/TYPOGRAPHY_V2/scroll_text1’]

ChatGPT

Sure! Here’s the updated script with the additional paths for switch indexes 5, 6, 7, and 8:

# me - this DAT
# channel - the Channel object which has changed
# sampleIndex - the index of the changed sample
# val - the numeric value of the changed sample
# prev - the previous sample value
# Make sure the corresponding toggle is enabled in the CHOP Execute DAT.

        6: ['/project1/base1/TYPOGRAPHY_V2/arranging_text'],
        7: ['/project1/base1/TYPOGRAPHY_V2/radial_tex'],
        8: ['/project1/base1/TYPOGRAPHY_V2/scroll_text1']
    }

    # Turn off all containers initially
    for paths in container_paths.values():
        for path in paths:
            container = op(path)
            if container:
                container.allowCooking = False

    # Check if the switch index is 5, 6, 7, or 8 and enable cooking for corresponding containers
    if switch_index in container_paths:
        for path in container_paths[switch_index]:
            container = op(path)
            if container:
                container.allowCooking = True
                print(f"Starting cooking for: {path}")
    else:
        print(f"Switch index {switch_index} is not in the range of 5, 6, 7, or 8")

    return

Explanation:

1. Added New Paths: The paths for switch indexes 5, 6, 7, and 8 have been updated to include the specified paths.

   5: ['/project1/base1/TYPOGRAPHY_V2/Text_Rip_OUT'],
   6: ['/project1/base1/TYPOGRAPHY_V2/arranging_text'],
   7: ['/project1/base1/TYPOGRAPHY_V2/radial_tex'],
   8: ['/project1/base1/TYPOGRAPHY_V2/scroll_text1']

2. Ensure the Script Monitors Value Changes: Make sure the appropriate toggle for Value Change is enabled in the CHOP Execute DAT.

3. Functionality: The script monitors the value changes in the OSC In channel, checks the switch index, and adjusts the cooking status of the containers based on the current index value.

This setup will now correctly monitor the specified paths for switch indexes 5, 6, 7, and 8, and manage their cooking states accordingly.

ChatGPT

The error indicates that the allowCooking flag can only be set for COMP operators, not for TOP operators (like nullTOP). To handle this, you need to ensure that the script is only trying to set the allowCooking flag on COMP operators. You can add a type check to make sure that the container is indeed a COMP before trying to set the allowCooking flag.

Here’s the revised script:

# me - this DAT
# channel - the Channel object which has changed

    return

Explanation:

1. Type Check: Added a check to ensure container.isCOMP before setting the allowCooking flag. This ensures the flag is only set for COMP operators.

   if container and container.isCOMP:
       container.allowCooking = False

2. Enable Cooking: Similarly, when enabling cooking, the same type check is applied.

   if container and container.isCOMP:
       container.allowCooking = True

This modification will prevent the script from attempting to set the allowCooking flag on non-COMP operators, avoiding the error you encountered.
