Trying to get my wall Jump to Work

Questions & Answers

Hey Guys. I’m trying to get my wall jump to work. Right now my character is only jumping straight into the air when he hits the wall. I want him to bounce the other direction he was moving when he jumps onto the wall? What kind of script would I use to do this? I’ve been trying to figure it out and cant. Take a look at the code I have so far.

private var canWallJump : boolean=false;
private var canWallJumpTime : float = 0;

var speed : float = 10.0;
var jumpSpeed : float = 10.0;
var gravity : float = 20.0;


    
    function Update () {    	
    	
    	var fwd = transform.TransformDirection (Vector3.forward);
        var controller : CharacterController = GetComponent(CharacterController);
       
       
           if (controller.isGrounded == false){
        		moveDirection = Vector3(Input.GetAxis("Vertical"),0);
        		moveDirection = transform.TransformDirection(moveDirection);
        		moveDirection *= speed;
        		canWallJump = true;
				canWallJumpTime = Time.time;
		//		canWallJumpDir = Vector3.Scale(Vector3(-1,0,-1), lastDirection);
				if(Time.time - canWallJumpTime > .25) canWallJump = false;
        		if(Physics.Raycast(transform.position, fwd, 1 && Input.GetButton("Jump") && canWallJump)) {
            		print("There is something in front of the object!");
            		moveDirection.y = jumpSpeed;
           	
        	}
        else{
        	print ("We are grounded");
        	}
        }
    // apply gravity
	moveDirection.y -= gravity * Time.deltaTime;
	
	// Move The controller
	controller.Move(moveDirection * Time.deltaTime);
	
	//last direction before wall contact
//	lastDirection = movement;
  }
	
@script RequireComponent (CharacterMotor)

There are some problems that I find with your code, hopefully one of them will fix your issue:

           moveDirection = Vector3(Input.GetAxis("Vertical"),0);
           moveDirection = transform.TransformDirection(moveDirection);
           moveDirection *= speed;

In this code you’re setting moveDirection to be similar to the input, but then you immediately override it with the forward direction, so the input is basically ignored.

if(Physics.Raycast(transform.position, fwd, 1 && Input.GetButton("Jump") && canWallJump)) {

Here it seems like you forgot one parenthesis. You are && the distance (1) with the input stuff. Try this instead:

if(Physics.Raycast(transform.position, fwd, 1) && Input.GetButton("Jump") && canWallJump) {
