You

Working in Touchdesigner. I’m using a chop execute to monitor an oscin chop (via a select), see picture. The osc in contains 5 channels. The first 4: angel, hero, feminist, rebel refer to different categories with incoming values. What I want to do in the chop execute is, if any of these channels are below a theshold number (eg.20) then I want certain containers to stop cooking

ChatGPT

To achieve your goal in TouchDesigner, you can modify the onValueChange function within your CHOP Execute DAT to check the values of your channels and stop cooking certain containers if any of the values fall below the specified threshold. Here’s how you can do it:

1. Define a threshold value.
2. Check the value of each channel.
3. Stop cooking the specified containers if the value is below the threshold.

Here is an example of how you can modify your 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 = 20
    container_paths = {
        'angel': 'path/to/angel/container',
        'hero': 'path/to/hero/container',
        'feminist': 'path/to/feminist/container',
        'rebel': 'path/to/rebel/container'
    }

    if val < threshold:
        container = op(container_paths[channel.name])
        if container:
            container.allowCooking = False

    return

Steps to Implement:

1. Set Threshold: Define the threshold value below which the containers should stop cooking. In this case, it’s set to 20.
2. Channel Names and Paths: Create a dictionary mapping the channel names to the paths of the corresponding containers.
3. Check Value and Stop Cooking: In the onValueChange function, check if the value of the channel is below the threshold. If it is, get the corresponding container and set its allowCooking attribute to False.

Notes:

• Ensure the paths to your containers are correctly specified in the container_paths dictionary.
• This script will stop cooking the containers when the value of any channel falls below the threshold.
• Make sure the CHOP Execute DAT is correctly connected and the necessary toggles are enabled.

This approach will dynamically monitor the incoming values and manage the cooking state of your containers based on the specified threshold.

Upon receiving a new message the containers should start cooking again if above the correct threshold

ChatGPT

To ensure that the containers start cooking again when the values are above the threshold, you can modify the script to enable cooking if the values exceed the threshold. Here is the updated 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 = 20
    container_paths = {
        'angel': 'path/to/angel/container',
        'hero': 'path/to/hero/container',
        'feminist': 'path/to/feminist/container',
        'rebel': 'path/to/rebel/container'
    }

    container = op(container_paths[channel.name])
    if container:
        if val < threshold:
            container.allowCooking = False
        else:
            container.allowCooking = True

    return

Key Modifications:

1. Enable Cooking: The onValueChange function now includes logic to enable cooking if the value is above the threshold.
2. Check Value: The script checks the value of each channel and adjusts the allowCooking attribute of the corresponding container accordingly.

Explanation:

• When the value of a channel falls below the threshold, the corresponding container’s allowCooking attribute is set to False.
• When the value of a channel rises above the threshold, the corresponding container’s allowCooking attribute is set to True.

This approach ensures that the containers will start cooking again once the incoming values exceed the threshold, allowing for dynamic control based on real-time data.

Traceback (most recent call last): File “/project1/base1/chopexec1”, line 29, in onValueChange KeyError: ‘newMessage’

ChatGPT

The error indicates that the channel name 'newMessage' is not found in the container_paths dictionary. To handle this situation gracefully, you should first check if the channel name exists in the dictionary before trying to access it.

Here is the updated script with the necessary checks:

# 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 = 20
    container_paths = {
        'angel': 'path/to/angel/container',
        'hero': 'path/to/hero/container',
        'feminist': 'path/to/feminist/container',
        'rebel': 'path/to/rebel/container'
    }

    # Check if the channel name exists in the dictionary
    if channel.name in container_paths:
        container = op(container_paths[channel.name])
        if container:
            if val < threshold:
                container.allowCooking = False
            else:
                container.allowCooking = True
    return

Key Modifications:

1. Check Channel Existence: Before accessing the container paths, the script checks if the channel.name exists in the container_paths dictionary.
2. Graceful Handling: If the channel name does not exist in the dictionary, the script will simply return without attempting to access the container paths, preventing the KeyError.

This modification ensures that the script only tries to manage containers for the defined channels, and it will not produce errors for any unexpected channel names like 'newMessage'.

You

please update the script using these paths:

‘angel’: ‘/project1/base1/ANGEL_FX’, ‘hero’: ‘/project1/base1/HERO_FX’, ‘feminist’: ‘/project1/base1/FEMINIST_FX’, ‘rebel’: ‘/project1/base1/REBEL_FX’

ChatGPT

Sure, here is the updated script with the specified container paths:

# 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 = 20
    container_paths = {
        'angel': '/project1/base1/ANGEL_FX',
        'hero': '/project1/base1/HERO_FX',
        'feminist': '/project1/base1/FEMINIST_FX',
        'rebel': '/project1/base1/REBEL_FX'
    }

    # Check if the channel name exists in the dictionary
    if channel.name in container_paths:
        container = op(container_paths[channel.name])
        if container:
            if val < threshold:
                container.allowCooking = False
            else:
                container.allowCooking = True
    return

Explanation:

• The container_paths dictionary has been updated with the specified paths.
• The rest of the script checks if the channel name exists in the dictionary and adjusts the allowCooking attribute of the corresponding container based on the value.

This updated script will now correctly handle the specified container paths for your project.

Angel: /project1/base1/ADD_FACE , /project1/base1/Angel_LUTS , /project1/base1/ANGEL_STAMPS , /project1/base1/ANGEL_POST

ChatGPT

Given the new paths for the ‘angel’ channel, we will need to update the script to manage multiple containers for each channel. Here’s the updated 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 = 20
    container_paths = {
        'angel': [
            '/project1/base1/ADD_FACE',
            '/project1/base1/Angel_LUTS',
            '/project1/base1/ANGEL_STAMPS',
            '/project1/base1/ANGEL_POST'
        ],
        'hero': ['/project1/base1/HERO_FX'],
        'feminist': ['/project1/base1/FEMINIST_FX'],
        'rebel': ['/project1/base1/REBEL_FX']
    }

    # 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)
            if container:
                if val < threshold:
                    container.allowCooking = False
                else:
                    container.allowCooking = True
    return

Key Changes:

1. Multiple Containers for ‘angel’: The container_paths dictionary now includes lists of paths for the ‘angel’ channel.
2. Iterate Over Paths: The script iterates over each path in the list for the given channel and adjusts the allowCooking attribute accordingly.

This updated script will manage multiple containers for each specified channel, ensuring they stop or start cooking based on the incoming values.

Let’s add some debugging to the script to ensure it is functioning as expected. We will print the values and check if the paths are correct.

Here is the updated script with added debugging:

# 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 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 = 20
    container_paths = {
        'angel': [
            '/project1/base1/ADD_FACE',
            '/project1/base1/Angel_LUTS',
            '/project1/base1/ANGEL_STAMPS',
            '/project1/base1/ANGEL_POST'
        ],
        '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

Debugging Steps:

1. Print Statements: Added print statements to display the channel name, value, and the paths being accessed.
2. Check Container Existence: Print whether the container is found at the specified path.

This will help us identify if the paths are being correctly accessed and if the allowCooking attribute is being properly set. Please check the console output in TouchDesigner to see the printed debug information and ensure that the paths and container objects are being accessed as expected.
