I don't know this is only happen when i upgrade my mac os to el capitan yesterday i reinstalled gamesalad i still have same problem but the projects thats come with gamesalad Big Top Blaster and other

Actors on scrollable layers do not collide properly with actors on un-scrollable ones. See this bug: http://bugs.gamesalad.com/show_bug.cgi?id=1368

Consider using an invisible actor in the same layer that is constrained to the position of the actor in the other layer and then set a collision rule on the invisible actor. You'll need to change the

and what can I do to make them collide knowing that I want to leave my actor in the HUD layer

You have them on a non-scrollable layer, like what was said in your thread below not sure why your asking this in my thread about universal build.

Make sure the density is all the same for all those actors. Make sure all the collide behaviors are at the top of the code stack and make sure all the actors are in the same layer.

So like in the title I have a problem with an actor. So my actor (1) is in a HUD layer, it has a control camera and it moves to the up.

The rule you posted is a really simple rule so if it's not working it's due to one of quite a few possible causes. Put a Log Debugging Statement at the top of that rule and watch the Debugger window

I want to know how to set up on a non-scrolling layer?

It looks like the locks might be placed on a non-scrolling layer but that is just a guess since I have no real idea how your project is set up.

or sometimes <5 just to be sure. Then I get this to trigger a game.attribute 'jumpattack', and in the enemy I have - if enemy collides with hero and 'jumpattack' is true, destroy.

Destroy.

anyone knows how to do a jump on enemy ? i have it so that when it collides with enemy health is changed to health - 1 , dont know how to make a bounce on top of the enemy to kill it, I tried to cons

But what I do know that if you want an event to occur(eg. Change scenes,destroy actor)when one actor touches another

So for example, a dot is moving side to side and theres a black line in the middle of where its going side to side. When i press to stop and it doesn't land on the dot, then resets the scene, but if t

and at level 31 you get Conveyor Belts - on top of the 'scenery' change.

In the roaming actor, when it collides with the player actor, if game.carrying is false then change self.following to true and then change game.carrying to true. Also in the roaming actor, when self.

destroy this actor

* You're limited to spawning behind/in front of the spawner actor or layer. Which is why you might want to consider having the first spawned actor spawn the next actor rather than using a separate sp
