Motion Scripting
/ PropertiesExpression controls properties
The value tracks behind expression controls, addressable as ordinary properties for keyframing and driving.
The value track behind each expression control - the same numbers control() hands to scripts, addressable as properties.
Every pattern below is readable from scripts through prop() and layer.prop(); ids in a pattern (like <effect_id>) stand for the entity's real id. Every pattern here is in the drive set: scripts may WRITE each one with set() or a single-output return, per frame.
| Pattern | Wire kind | Units | Reads | Writes |
|---|---|---|---|---|
expression_controls.<control_id> | scalar | number (wire units of the key) | yes | drive set |
