Recoil and Gun Movement JavaScript issues.

Unity Engine
1

Ok, I have a recoil and gun movement script that has been causing me a bit of trouble. The movement works, but the recoil does not. The recoil pushes the gun back but does not bring it back forward. Also, this isn’t a big issue but the way the gun sways when I move, it seems a bit slow and under exaggerated. If you have any idea what it wrong or how I could fix it, please post your answers. Every answer will be appreciated greatly because I am new to Unity and somewhat a beginner with Javascript. Here is my script:

#pragma strict
var MoveAmount : float = 1.0f;
var MoveSpeed : float = 2.0f;

var gunModel : GameObject;
var cameraModel : GameObject;

var MoveOnX : float = 0.0f;
var MoveOnY : float = 0.0f;

var DefaultPos : Vector3;
var NewGunPos : Vector3;

var DefaultRot : Quaternion;
var NewGunRot : Quaternion;

var ONOFF : boolean = false;

var recoilAmount : float = 0.0f;
var amountToRecoil : float = 0.0f;

var recoilMultiplier : float = 1.0f;

var recoilMax : float = 0.0f;
var recoilMin : float = 0.0f;
var rotationMultiplier : float = 10.0f;

function Awake () {
	NewGunRot = DefaultRot;
	DefaultPos = transform.localPosition;
	ONOFF = true;
}


function Update () {
	if(Input.GetMouseButtonDown(1)){
		ONOFF = false;
	}
	if(Input.GetMouseButtonUp(1)){
		ONOFF = true;
	}
	if(Input.GetMouseButton(0)){
		recoilAmount += amountToRecoil;
	}
	if(recoilAmount >= recoilMax){
		recoilAmount = recoilMax;
	}
	if(recoilAmount <= recoilMin){
		recoilAmount = recoilMin;
	}
	if(Input.GetMouseButtonDown(0)){
		recoilAmount -= (amountToRecoil / 2);
	}
}

function LateUpdate () {
	if(ONOFF == true) {
		MoveOnX = Input.GetAxis("Mouse X") * Time.deltaTime * MoveAmount;
		MoveOnY = Input.GetAxis("Mouse Y") * Time.deltaTime * MoveAmount;
		
		NewGunPos = new Vector3(DefaultPos.x+MoveOnX,DefaultPos.y+MoveOnY,DefaultPos.z - (recoilAmount * recoilMultiplier));
	
		gunModel.transform.localPosition = Vector3.Lerp(gunModel.transform.localPosition, NewGunPos, MoveSpeed * Time.deltaTime);
	}
	NewGunRot = Quaternion.Euler(DefaultRot.x, DefaultRot.y, DefaultRot.z - (recoilAmount * recoilMultiplier) * recoilMultiplier);

gunModel.transform.localRotation = NewGunRot;
}

Lines 61 and 63 look okay in terms of syntax. Looks like it’s something you’re doing to recoilAmount. From your description you’re setting it right once, but it doesn’t return to the expected original value. That’s what you ought to look into to debug this. Good luck!

Thanks! I figured it out, the recoil amount, for some reason when it was a positive value it kept the gun pushed back so I made it a negative value and the recoil worked perfectly!

thank you very much, perfect
