Parameter Manipulation in Cubism SDK for Cocos Creator

Updated: 03/14/2023

When manipulating the values of model parameters in Cubism SDK for Cocos Creator, it is necessary to do so at the timing of Component.lateUpdate() in Cocos Creator’s event function.

The process of playing the AnimationClip is performed between Component.update() and Component.lateUpdate() in Cocos Creator’s event functions.
If the parameter value is manipulated with Component.update(), it will be overwritten by the value of the AnimationClip that is played immediately after.
Therefore, any manipulation of parameter values should be done after AnimationClip has set the values.

All components included with Cubism SDK for Cocos Creator manipulate parameter values from Component.lateUpdate().

Also, since the model’s vertex update process from the parameter values at each frame is performed in Cocos Creator’s post-draw event (Director.EVENT_AFTER_DRAW), any value manipulation later than this will not be calculated.
