OP Execute DAT

From TouchDesigner 099 Wiki

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.
