Question by awplays49 · Mar 27, 2015 at 10:37 PM · movementrigidbodyvelocity

Issue with velocity movement script

Hi!

Recently I changed my script for movement from transform.position to the following movement:

 if (Input.GetKey (KeyCode.W))
         {
             if (IsMoving [0] == false)
             {
                 GetComponent <Rigidbody> ().velocity += transform.forward * Speed;
                 IsMoving [0] = true;
             }
         }
         else if (IsMoving [0] == true)
         {
             GetComponent <Rigidbody> ().velocity -= transform.forward * Speed;
             IsMoving [0] = false;
         }

problem is when i walk into a wall and let go of w, it'll move me back. i thought subtracting forward velocity would stop me from moving, but when colliding with something in front of me and letting go of w, i move backwards, How can i improve this script? thanks!

EDIT

So I've been thinking, and i thought maybe what i need is a way to remove all forward velocity… how to do?

Your script confuses me, but I understand what it's doing.

If I weren't to rewrite the script, I would just add:

 void OnTriggerEnter(Collider col){
 if(col.tag == "Wall"){
 GetComponent<Rigidbody>().velocity = 0;
 }
 }

thats not the problem. the problem is when i collide with the wall, which automatically lowers my velocity. then i let go of w, and i move backwards.

Okay, hold on. I'll test it out. Trying to understand what you mean.

How about:

 if(Get$$anonymous$$eyUp($$anonymous$$eyCode.W))
 velocity *=-1;
