Crouching shape changer

Is it possible to make it where the size and collider size can be changed in game using code?
I need this to make my bean players crouch.

Hi @Gavin_Durbin,

Yes, it’s possible to change the size of a collider in code, example changing the height of a capsule or cylinder collider:

entity.collision.height = newColliderHeight;

Oops. Something like that would leave me with an annoying or unnoticed bug. Why are such things not being done behind the scenes?

Actually it’s indeed being handled, I take it back and editing by post above. I may have observed that behavior in an older engine version or while doing something custom of my own:

playcanvas/engine/blob/0a0fb7a63304f30481a69a87163ecb74a5af32e9/src/framework/components/collision/system.js#L122


            this.system.recreatePhysicalShapes(component._compoundParent);
        } else {
            this.system.updateCompoundChildTransform(entity);
            if (component._compoundParent.entity.rigidbody)
                component._compoundParent.entity.rigidbody.activate();
        }
    }
}
if (entity.rigidbody) {
    entity.rigidbody.disableSimulation();
    entity.rigidbody.createBody();
    if (entity.enabled && entity.rigidbody.enabled) {
        entity.rigidbody.enableSimulation();
    }
} else if (! component._compoundParent) {
    if (! entity.trigger) {
        entity.trigger = new Trigger(this.system.app, component, data);
    } else {

Good to hear. Thank you for checking it out!
