Chop Execute DAT Control

You

I’m working in touchdesigner. I have 4 Chop Execute DATs that I want to turn on and off based on which of 4 osc channels is the highest. I want to repurpsoe this script so that instead of changing the switch index I instead turn the corresponding Chop Execute DAT on or off

def valueChange(channel, sampleIndex, val, prev): # Get the operator (CHOP) this DAT is monitoring chop = channel.owner

# Get the values of the channels
angel = chop['angel'][0]
hero = chop['hero'][0]
feminist = chop['feminist'][0]
rebel = chop['rebel'][0]

# Find the channel with the highest value
values = [angel, hero, feminist, rebel]
max_index = values.index(max(values))

# Set the index of the switch
op('switch1').par.index = max_index

return

To modify your script to turn on and off the corresponding Chop Execute DAT based on which of the four osc channels is the highest, you can use the enable parameter of each Chop Execute DAT to control their activation. Here is how you can repurpose the script:

1. Define the paths or names of the Chop Execute DATs you want to control.
2. Enable the Chop Execute DAT corresponding to the channel with the highest value and disable the others.

Here is the modified script:

def valueChange(channel, sampleIndex, val, prev):
    # Get the operator (CHOP) this DAT is monitoring
    chop = channel.owner

    # Get the values of the channels
    angel = chop['angel'][0]
    hero = chop['hero'][0]
    feminist = chop['feminist'][0]
    rebel = chop['rebel'][0]

    # Find the channel with the highest value
    values = [angel, hero, feminist, rebel]
    max_index = values.index(max(values))

    # Define the paths or names of the Chop Execute DATs
    chop_exec_dats = [
        op('chop_execute_angel'),
        op('chop_execute_hero'),
        op('chop_execute_feminist'),
        op('chop_execute_rebel')
    ]

    # Turn on the Chop Execute DAT with the highest value and turn off the others
    for i, chop_exec_dat in enumerate(chop_exec_dats):
        chop_exec_dat.par.enable = (i == max_index)

    return

Explanation:

1. Retrieve Channel Values: This part of the script remains unchanged, where you retrieve the values from the osc channels.
2. Find the Maximum Value: Again, this part is the same, where you determine which channel has the highest value.
3. Control Chop Execute DATs: Instead of changing the switch index, you define a list of your Chop Execute DAT operators. Then, you iterate over this list and set the enable parameter of the corresponding Chop Execute DAT based on the index of the maximum value. Only the Chop Execute DAT with the highest value’s index is enabled, and the rest are disabled.

Make sure the names or paths of the Chop Execute DATs in the chop_exec_dats list are correct according to your TouchDesigner project.

The error indicates that the enable parameter does not exist in the td.ParCollection object as expected. In TouchDesigner, the correct way to enable or disable a CHOP Execute DAT is to use the bypass parameter instead of enable.

Here’s the corrected script using the bypass parameter:

def valueChange(channel, sampleIndex, val, prev):
    # Get the operator (CHOP) this DAT is monitoring
    chop = channel.owner

    # Get the values of the channels
    angel = chop['angel'][0]
    hero = chop['hero'][0]
    feminist = chop['feminist'][0]
    rebel = chop['rebel'][0]

    # Find the channel with the highest value
    values = [angel, hero, feminist, rebel]
    max_index = values.index(max(values))

    # Define the paths or names of the Chop Execute DATs
    chop_exec_dats = [
        op('chop_execute_angel'),
        op('chop_execute_hero'),
        op('chop_execute_feminist'),
        op('chop_execute_rebel')
    ]

    # Turn on the Chop Execute DAT with the highest value and turn off the others
    for i, chop_exec_dat in enumerate(chop_exec_dats):
        chop_exec_dat.par.bypass = (i != max_index)

    return

Explanation:

1. Retrieve Channel Values: This part remains the same, where you retrieve the values from the osc channels.
2. Find the Maximum Value: This part also remains unchanged, where you determine which channel has the highest value.
3. Control Chop Execute DATs: You define a list of your Chop Execute DAT operators. Then, you iterate over this list and set the bypass parameter of the corresponding Chop Execute DAT based on the index of the maximum value. The Chop Execute DAT with the highest value’s index is not bypassed (active), and the rest are bypassed (inactive).

This should properly enable and disable the Chop Execute DATs based on the highest value among the osc channels.

It seems there is some confusion regarding the parameters. The Chop Execute DAT might not have a bypass parameter directly accessible like this. Instead, you can use the par attribute to enable or disable scripts by modifying a parameter that controls execution, such as active.

Here’s the revised script using the active parameter:

def valueChange(channel, sampleIndex, val, prev):
    # Get the operator (CHOP) this DAT is monitoring
    chop = channel.owner

    # Get the values of the channels
    angel = chop['angel'][0]
    hero = chop['hero'][0]
    feminist = chop['feminist'][0]
    rebel = chop['rebel'][0]

    # Find the channel with the highest value
    values = [angel, hero, feminist, rebel]
    max_index = values.index(max(values))

    # Define the paths or names of the Chop Execute DATs
    chop_exec_dats = [
        op('chop_execute_angel'),
        op('chop_execute_hero'),
        op('chop_execute_feminist'),
        op('chop_execute_rebel')
    ]

    # Turn on the Chop Execute DAT with the highest value and turn off the others
    for i, chop_exec_dat in enumerate(chop_exec_dats):
        chop_exec_dat.par.active = (i == max_index)

    return

Explanation:

1. Retrieve Channel Values: This part remains unchanged, where you retrieve the values from the osc channels.
2. Find the Maximum Value: This part also remains the same, where you determine which channel has the highest value.
3. Control Chop Execute DATs: You define a list of your Chop Execute DAT operators. Then, you iterate over this list and set the active parameter of the corresponding Chop Execute DAT based on the index of the maximum value. Only the Chop Execute DAT with the highest value’s index is active, and the rest are inactive.

This should properly enable and disable the Chop Execute DATs based on the highest value among the osc channels. If the active parameter does not exist, you might need to check the exact parameter name used to control the execution of your Chop Execute DAT and replace it accordingly.
