Question by Chieze · Nov 17, 2019 at 04:50 AM · 2d-platformer2d physics

Prevent Velocity from being overriden

I'm working on a 2d plat former and I want to have a wall jump. The problem is that when you jump of the wall the force is immediately removed the next frame. how would i avoid that without having the movement speed buildup? Samples:

     //add movement
         moveVelocity.x = Input.GetAxis("Horizontal") * speed;
         velocity.x = moveVelocity.x;
     //velocity that is added when wall jumping    
         velocity.x += wallJumpHeight;

I'm not sure I understood the question, but if you're using Rigidbody for movement, then set force mode to impulse

 AddForce(direction, ForceMode2D.Impulse); 

Sidenote: Don't modify velocity on non-kinematic rigidbodies directly, unless you know what you're doing)
