4.4.1
I have an object in my game with RigidBody2D node. I want to make any other objects like player or throwable blocks bounce of it (literally Minecraft slime block mechanic). I didn’t find any tutorial, how to make it work, and I can’t do it myself too. All tutorials tell me, how to make one object bouncing of everything with Physics Material, but that’s not what I need, it’s like inverted Physics Material.
Do somebody know, how to make it work?
Okay so you can check that is there any physics body’s getting detected above the surface (Using Area2D node), then you can push (actually apply force in the y axis) to the body in the Y axis to seem like it’s bouncing. And also, you can add more natural feel you slightly decreasing the force 
There is a tutorial on it ,he’s doing it in the same way Tutorial
I’d like to do this. Moreover, I tried doing this, but it works only for one direction, and I want to make object bounce of all of the sides
Then you can add force to the x axis as well based on the player movement or what you want .
