I have a sidescroller level put together most of the problems have been fixed so far Thanks to the help from these forums but now I noticed that the enemy character drops between the floor tiles (which have a solid behavior) the enemy has 4 animations walk,attack,idle,defeated I created the animations in spriter and 3 of the animations work fine except the attack animation I was wondering is there any reason why the enemy character drops under the floor surface on the attack animation? I tried putting a platform behavior on the enemy but the enemy follows the player characters movement unless I delete the platform behavior.
