Experimental:Run Command Examples
This page is also posted as a tutorial with an attached example file on the Derivative website here.
The following examples are meant to be pasted into a textDAT. You can then run them (RMB>Run Script or select and ctrl-R) and see the results in a textport.
The Run Command
The run command allows you to run a string as a Python statement. It has many a number of options available as to how to run the command. The most powerful feature of these options is to allow you to delay the execution for a certain number of frames or milliseconds. Below is the full wiki documentation for run. This tutorial will go through all the options one by one.
run(script, arg1, arg2..., endFrame=False, fromOP=None, asParameter=False, group=None, delayFrames=0, delayMilliSeconds=0, delayRef=me)→
Run the script, returning a Run object which can be used to optionally modify its execution. This is most often used to run a script with a delay, as specified in the delayFrames or delayMilliSeconds arguments.
- script - A string that is the script code to execute.
- arg - (Optional) One or more arguments to be passed into the script when it executes. They are accessible in the script using a tuple named args.
- endFrame - (Keyword, Optional) If True, the execution will be delayed until the end of the current frame.
- fromOP - (Keyword, Optional) Specifies an optional operator from which the execution will be run relative to.
- asParameter - (Keyword, Optional) When fromOP used, run relative to a parameter of fromOP.
- group - (Keyword, Optional) Can be used to specify a string label for the group of Run objects this belongs to. This label can then be used with the td.runs object to modify its execution.
- delayFrames - (Keyword, Optional) The number of frames to wait before executing the script.
- delayMilliSeconds - (Keyword, Optional) The number of milliseconds to wait before executing the script. This value is rounded to the nearest frame.
- delayRef - (Keyword, Optional) Specifies an optional operator from which the delay time is derived. You can use your own independent time component or
op.TDResources, a built-in independent time component.
Running A Simple Script
At its most basic,
run allows you to execute a string as a Python script. The following is exactly the same as if you had executed the
script argument without wrapping it in the
