	if action_id == hash('action') and action.pressed then
		  print('o')

Can you see the “o” in the console log when you press the action? If so, then it is working, but at any rate your force is way too small to be noticeable. Try a force of 1000 or 10000. The “apply_force” message will only apply that force for one frame.

Also, check your input settings :slight_smile: Maybe you forgot to add some button to action hash actually.

It’s hard to give any pointers without knowing more about your game setup. Do you have a collision object attached to the game object you are applying force to?

If you like you can invite me to the project and I can have a look, johan.beck-noren[at]king.com

The “apply_force” message is only for collision object components with their type set to “dynamic” (simulated rigid bodies). It’s the only way to interact with them, and it doesn’t work for any other type of collision object or any other component or game object. To move normal things around you use go.set_position() or go.animate().
