so if i define a backdrop as an obstacle, how do i make it work? i mean i tried it but the player character goes straight through it?

All activities/events are done in the event editor. So if you want the player character (PC) to stop moving when colliding with an obstacle, go to the event editor and make this event:

[events]
*[PC] Collides with backdrop
-[PC] Bounce
[/events]

You find the Collide condition under Collisions and the Bounce action under Movement.

yeah, i know that i do it like this now, but then whats the point in the collision type setting?

A backdrop will by default not be treated like an obstacle. That is because you probably don't want your active objects to collide with all backdrops. Some backdrops are there just to spice up the environment. In the collision type setting you simply select how the object shall be treated in the eventeditor.

The "Platform" and "Ladder" backdrop types are for use with the default platform movement, so the only two that really matter are the "None" (a decorative backdrop) and "Obstacle" (objects will be counted as colliding with the backdrop when they're over it). You also need to set up what to do about colliding with obstacle backdrops in the events, as described above... though I'd say to use the "Stop" action - I'm not sure where the idea of "Bounce" came from. Default movements have automatic correction for pulling out of walls once they've collided with them, and so on.

I wouldn't use the "bounce" event, as I have found it quite buggy (when bouncing into a wall a few times, you might get stuck)
