double jump

Questions & Answers

Hi guys I’m working on a 2d platform game and i’ve got the code from the unity tutorial “Lerpz”. Now I want my character to do a double jump. You press jump once… he jumps normal. When you press it while he’s jumping normal again you do a frontflip. Here is the code… I already tried some things but nothing worked:

Hi, I redid and tested the code and it works perfectly. Feel free to tweak the values.

#pragma strict

@script RequireComponent(Rigidbody); //forces this gameObject to also have a rigibody component

//public variables

var maxAirJumpCount : int = 1; // 1 for a double jump

var normalJumpForce : float = 8; //strength of the normal jump's impulse
var airJumpForce : float = 5; //strength of the double jump's impulse

var raycastDistance : float = 1; //distance between the characters origin and the ground, 1 for a 2m high character

var xSpeed : float = 10; // horizontal speed of the character

/* These values are all ideal settings that worked for me */

//private variables

private var airJumpCount : int = 0; //how many more times can the player jump?

private var xMove : float; // horizontal input (Input.GetAxisRaw("Horizontal")) *
							// horizontal speed modifier (xSpeed)

private var isGrounded : boolean = false; //is the player on the ground?

function Update() {

	if(Physics.Raycast(transform.position, -Vector3.up, raycastDistance)) {
		
		isGrounded = true;
		airJumpCount = maxAirJumpCount;
	}
	else {
		
		isGrounded = false;
	}

	if(Input.GetKeyDown(KeyCode.Space)) {
		
		if(isGrounded) {
			JumpNormal();
		}
		else if(airJumpCount > 0) {
			
			airJumpCount -= 1;
			JumpInAir();
		}
	}

	xMove = 0;
	xMove = Input.GetAxisRaw("Horizontal") * xSpeed;

}

function FixedUpdate () {
	rigidbody.AddForce(Vector3.right*xMove);
}


function JumpNormal () { rigidbody.AddForce(Vector3.up * normalJumpForce, ForceMode.Impulse); }

function JumpInAir () { rigidbody.AddForce(Vector3.up * airJumpForce, ForceMode.Impulse); }

OHH It worked if somebody wants the script here’s the link
