Hi
I use hammer editor to create a simple map. I know how I can use the trigger: when player touch the "zone" I can start animation/action to other object. But, how I can start animation/action when this trigger is touched from another object (cube or other physic object for example)?

Thanks and excuse me for my poor english

In the trigger flags should be the option to react to "physics objects". If it can be any physics object then that's all you need. If it should react only to a certain cube for example, you need to use a filter for the trigger.

Perfect, it works fine! THANK YOU zivi7!
