Hi, is it possible to use gameplay action on one specific object? When i touch the action button, i want to use it on one object only.
No it is not. But maybe it is better if you describe what do you want to achieve and see if there is another way to do that...
Warp changes the physics engine settings which is for the entire world. You might can achieve this with Logic which can be set for a specific object.
inside the action animation make the object as a platform that collide with characters and other platforms or objects
