yes, you can test for a specific object (overlapping or on collision) or you can set an instance variable on certain wall objects and test for it using the same types of events (overlapping or collision) and then adjust your conditions so that it tests for that value before allowing the double jump action the same way we test for a wall or the jump phase in my tutorial.
@statham @jogosgratispro You can add the walls you want to be jumpable to a family. Then in your condition for wall jumping test to see if you are colliding with that family.
In my current game I have wall jumping as well as wall sliding (clinging to walls and sliding down slowly) I didn't want the player to be able to slide/cling to walls made of Ice so I made a family called slideablewalls and added all but the ice tileset to it. Then in my condition I test to see if the player is overlapping slideablewalls.BluePhaze2013-11-20 20:35:47
