  2. OP Execute DAT

    OP Execute DAT

    Summary

    The OP Execute DAT runs a script when the state of an operator changes.

    OP Execute DATs are created with default python method placeholders. For each monitored condition in the parameters, there is a matching python method in the DAT. When a condition is turned on in the parameters, each time that condition is satisfied the corresponding python method will be executed.

    Parameters - OP Execute Page

    Active active - While on, the DAT will respond to the OP that is referenced.

    Execute from executeloc - ⊞ - (Tscript only) Determines the location the script is run from.

    • Current Node current - (Tscript only) The script is executed from the current node location.
    • This Node here - The script is executed from the parent of the DAT. The DAT executes from the parent to make siblings of the DAT easy to access: DAT scripts used to execute from inside the DAT.
    • Specified Operator op - The script is executed from the operator specified in the From Operator parameter below.

    From Operator fromop - The path that the script will be executed from if the Execute From parameter is set to Specified Operator.

    Monitor OPs op - Specify which operators to monitor to trigger the scripts.

    Pre Cook precook - The onPreCook() method is triggered before the operator is cooked.

    Post Cook postcook - The onPostCook() method is triggered after the operator is cooked.

    Destroy opdelete - The onDestroy() method is triggered when the operator is deleted.

    Flag Change flagchange - The onFlagChange() method is triggered when one of the operator's Flags changes state. This includes all the flags in the Common Flags list of an OP_Class, plus all the python accessible flags listed in COMP_Class, SOP_Class, CHOP_Class.

    Wire Change wirechange - The onWireChange() method is triggered when the operator's inputs are rewired (connected, disconnected, swapped).

    Name Change namechange - The onNameChange() method is triggered when the name of the operator is changed.

    Path Change pathchange - The onPathChange() method is triggered when the path of the operator is changed.

    UI Change uichange - The onUIChange() method is triggered when operator is resized or moved in the network editor.

    Number Children Change numchildrenchange - The onNumChildrenChange() method is triggered if the number of children an operator has changes. Only works with Component type operators.

    Child Rename childrename - The onChildRename() method is triggered if a child of the operator is renamed.

    Current Child Change currentchildchange - The onCurrentChildChange() method is triggered if a child of the operator is made current in a network. Only works with Component type operators.

    Extension Change extensionchange - The onExtensionChange() method is triggered when an extension of the operator is changed.

    Edit.. edit - Clicking this opens a text editor to edit text in the DAT.

    Language language - ⊞ - Select how the DAT decides which script language to operate on.

    • Input input - The DAT uses the inputs script language.
    • Node node - The DAT uses it's own script language.

    Edit/View Extension extension - ⊞ - Select the file extension this DAT should expose to external editors.

    • dat dat - various common file extensions.
