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.

Parameters - Common Page

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.

• From Language language - pick extension from DATs script language.

• Custom Extension custom - Specify a custom extension.

Custom Extension customext - Specifiy the custom extension.

Word Wrap wordwrap - ⊞ - Enable Word Wrap for Node Display.

• Input input - The DAT uses the inputs setting.

• On on - Turn on Word Wrap.

• Off off - Turn off Word Wrap.

Operator Inputs

• Input 0 -

An Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a command Script, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.

The generic thing that holds an Operator, and includes Flags (display, bypass, lock, render, immune) and its position/size in the network. Whether you "lay down an Operator" or "lay down an Node", you're doing the same thing.

Any of the procedural data operators. OPs do all the work in TouchDesigner. They "cook" and output data to other OPs, which ultimately result in new images, data and audio being generated. See Node.

To re-compute the output data of the Operators. An operator cooks when (1) its inputs change, (2) its Parameters change, (3) when the timeline moves forward in some cases, or (4) Scripting commands are run on the node. When the operator is a Gadget, it also cooks when a user interacts with it. When an operator cooks, it usually causes operators connected to its output to re-cook. When TouchDesigner draws the screen, it re-cooks all the necessary operators in all Networks, contributing to a frame's total "cook time".

(1) Indicator of certain states of an operator (bypass, display, lock), or (2) option of a Tscript command.

The connection of an output of one node to the input of another node in a network. In contrast, see Link.

The location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.

An Operator Family that contains its own Network inside. There are twelve 3D Object Component and eight 2D Panel Component types. See also Network Path.
