The Script CHOP runs a script each time the Script CHOP cooks. By default, the Script CHOP is created with a docked DAT that contains three Python methods:
cook method is run each time the Script CHOP 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: Because the Script CHOP can get data from anywhere, it's difficult to determine what it procedurally depends on. So every time that any 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.
Parameters - Script Page
callbacks - Specifies the DAT which holds the callbacks.
setuppars - Clicking the button runs the
setupParameters() callback function.
Parameters - Common Page
timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.
scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.
Sample Rate Match
srselect - ⊞ - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.
- Resample At First Input's Rate
first- Use rate of first input to resample others.
- Resample At Maximum Rate
max- Resample to the highest sample rate.
- Resample At Minimum Rate
min- Resample to the lowest sample rate.
- Error If Rates Differ
err- Doesn't accept conflicting sample rates.
exportmethod - ⊞ - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.
- DAT Table by Index
datindex- Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
- DAT Table by Name
datname- Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
- Channel Name is Path:Parameter
autoname- The channel is the full destination of where to export to, such has
autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
- Input 0 -
