gravity, movable and immovable actors

How do I make a movable actor 'stand on' an immovable actor in a scene that has gravity? Every thing I try results in the movable actor plunging to its death.

    Use Accelerate down behavior on actors instead of gravity. then don't use it on actors that you don't want to have gravity.

    I really need gravity for this game to handle the physics and collisions. I just need to be able to stand a movable object on an immovable one. Can it be done or no?

    you can constrain the position of the object's X and Y.

    I guess I'm not sure what good gravity is then if immovable objects dont act as barriers to movable ones? I tried the path of not using gravity, but I'm making a 'power meter jumping' game and it's much harder trying to inverse everything without gravity than to just let things fall until something stops them.

    Anyone else have any thoughts here?

    un tick movable in the physics on the actor

    My understanding is that that attribute is read only at run time. Can someone verify: there is no way for an immovable object to stop a movable object from moving past it with gravity in effect? Not a density setting, not a layer positioning, etc?

    You could completely ignore my post. Also set the restitution of both to 0.

    In your unmovable actor, just add a Collide behavior(s). Specify which actors you want that actor to collide with.

    Any actor can collide with any other actor.
