How to make two objects collide without bouncing 2D

https://youtu.be/10y4BDnhadQ 55 sec long

Here is a player who should collide with stones(please ignore trees and caves). Sometimes it $$anonymous$$ts them, sometimes not. It should act the same everytime, like it does with the border. For example at ''38 the rabbit goes down when it should $$anonymous$$t the stone. The stones should act like obstacles(the player should not move through them and remain where it is). The objects w$$anonymous$$ch appear at 'play' are randomly generated.
