How to make Sprite not Bounce on Collision (2D)

Thank you I really appreciate your help.

Nice this fixed it

Thank you SO much! I think I see why that worked too. I really should use Fixed more often.

I literally went through the pain of signing in to say thank you because you solved my problem chief

i don't know why, but for some reason it doesn't let me apply my custom physics material on the Sprite Renderer $$anonymous$$aterial, i can do that only on collider objects.

The are two types of materials, rendering and physics. You can't use a physics material on the spriterenderer because it needs a rendering material.

Thank you very much! but as i see a rendering material doesn't have "bounciness" property... i fixed the problem a little using FixedUpdate() function ins$$anonymous$$d of Update() so it doesnt keep bouncing if i keep the arrow pressed. but still i can see a small bounce on the first collision. I don't know where else can i find properties about this?

You miss understood me, rendering materials have absolutely nothing to do with physics. They only effect what is rendered.

Physics materials are only on colliders. Your character and your terrain should have colliders and all of the colliders need bounciness set to 0.

Character needs bounciness 0 as well as the terrain.
