Script DAT

Jump to: navigation, search


The Script DAT runs a script each time the DAT cooks and can build/modify the output table based in the optional input tables. The Script DAT is created with a docked (attached) DAT that contains three Python methods: cook, onPulse, and setupParameters. The cook method is run each time the Script DAT cooks. The setupParameters method is run whenever the Setup Parameter button on the Script page is pressed. The onPulse method is run whenever a custom pulse parameter is pushed.

Refer to Help -> Python Examples, and Help -> Operator Snippets.

Note: Every time that a Script OP runs it will make a list of operators, parameters, nodes etc that it depends upon, and when they change, the Script OP will re-cook.

A set of commands located in a Text DAT that are triggered to run under certain conditions. There are two scripting languages in TouchDesigner: Python and the original Tscript. Scripts and single-line commands can also be run in the Textport.

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.
