can anyone help i was able to load my map but there is no background detection.

What do you mean?

Probably no background collision with the upper sprites.

in the map editor i created a map but when i load it my sprite just runs over the objects i set to stop it.

the objects don't stop the sprite on their own. you have to program the collision.

Thamks just watched petit professor 3d's video on backround detection.

thanks not thamks
