2D sidescroller shooting
I made the arm rotate using wasd using this code:
public class ArmRotation : MonoBehaviour {
public int armRot = 0;
// Use this for initialization
// Update is called once per frame
void Update () {
if(Input.GetButton("AimUp")&&Input.GetButton("AimSide"))
armRot = 45;
else if (Input.GetButton("AimDown"))
armRot = -45;
else if (Input.GetButton("AimUp"))
armRot = 90;
else armRot = 0;
transform.rotation = Quaternion.Euler(0f,0f, armRot );
}
}
but i can't figure out how to make my gun shoot properly i tried this but it doesn't work :
public class WeaponScript : MonoBehaviour {
public float fireRate = 0;
public float Damage = 10;
public LayerMask notToHit;
float timeToFire = 0;
Transform firePoint;
Transform firePoint2;
// Use this for initialization
void Awake () {
firePoint = transform.FindChild ("FirePoint");
if (firePoint == null){
Debug.LogError ("FirePoint not found");
}
firePoint2 = transform.FindChild ("FirePoint2");
if (firePoint == null){
Debug.LogError ("FirePoint2 not found");
}
}
// Update is called once per frame
void Update () {
if (fireRate == 0){
if (Input.GetButtonDown("Fire")){
Shoot();
}
}
else {
if (Input.GetButtonDown("Fire")&& Time.time > timeToFire){
timeToFire = Time.time + 1/fireRate;
Shoot();
}
}
}
void Shoot (){
Vector2 firePointPosition = new Vector2 (firePoint.position.x, firePoint.position.y);
Vector2 firePointPosition2 = new Vector2 (firePoint2.position.x, firePoint2.position.y);
Debug.DrawLine (firePointPosition, firePointPosition2, Color.red);
RaycastHit2D hit = Physics2D.Raycast(firePointPosition, firePointPosition2- firePointPosition);
}
}
where firePoint is a empty game object next to the barrel and firePoint2 is a empty game object located in front of the barrel (by 0.3 units)
The logic for determining if you can shoot in your Update method is... ehh, FUBAR.
Basically if you just want to have a delay between firing, simply use this:
public float RefireDelay = 1f;
private float _refireDelay;
public void Start()
{
_refireDelay = RefireDelay;
}
public void Update()
{
_refireDelay -= Time.deltaTime;
if (_refireDelay < 0)
{
Shoot();
_refireDelay = RefireDelay;
}
}
Keep your Shoot functions, and all public variables and transforms.
Don't use Time.time, use deltaTime, that's a time difference that elapsed between last frame and this one.
When comparing float values, never use == operator because it will never return true. Your float timers will never be EXACTLY 0 values, it will go from 0.005123 to -0.0110293 or something like that. So always check less or more, never equal, with time and other floating point values.
