I am moving a platform sideways & up and down (it is some sort of air ship/glorified elevator). The objects that are on it, fly off when the platform starts to move.
The platform itself doesn’t simulate physics, just collision.
I try to add Friction, Damping, increase Mass… doesn’t work.
The objects needs to remain movable (the player can also pick/drad/push them)
Does anyone have a solution?
Ok, I found a solution. Maybe can be helpful to someone, although I have to work on it a bit more, because it have some shortcomings… but overall it’s this.
First, quick solution - works if your platform moves only sideways. Increasing the “Inertia Tensor Scale” of the physical objects will make them fixed to your moving platform. You can still pick them up and move them.
But if your platform starts to descend/go down, the objects will fly off again. Increasing their mass doesn’t seems to work to prevent this.
So the solution is to Attach them + weld them and turn off Simulate Physics (turn out it’s kind of important)
To do that In your moving platform you need a collision box to detect what objects are overlapping.
I am detecting when the platform starts to move or stops moving completely via velocity check. So two events created in the platform BP: Start and Stop. Here is a screenshot:
And this is the set up in the pickable objects:
So, when the platform moves, the objects are not pickable, but attached and move with the platform. When the platform stops, they can be moved.
