Make a Gun fire multiple times

Archived Forums Questions & Answers

I have a gun and need it to fire when I am holding down the left mouse button until a specific number of bullets fired is reached, then i reload. The script I have right now Instantiates a sphere and adds a force to it, but its only a one shot and doesnt have the bullet limit or reload function. I can add the reload and bullet limits myself i think, but im really stuck on the fire rate.

I tend to use Time.deltaTime and Mathf.Max like so:

float timeTillNextShot = 0;

void Update()
{
timeTillNextShot = Mathf.Max(timeTillNextShot - Time.deltaTime, 0);   //never go below 0

if(timeTillNextShot <= 0)    //Add condition to check if we're firing here
{
timeTillNextShot = timeBetweenShots;   //reset
fireAShot();
}
}

Just use a bool check with InvokeRepeating().

public bool mousePressed = false;
public float timeBetweenShots = 0.2f;
public int shotsPerClip = 30;

private bool runOnce = false;

void Update()
{
   if(Input.GetMouseDown(0)){
     mousePressed = true;
   }
   if(Input.GetMouseUp(0)){
     mousePressed = false;
   }

   if(mousePressed){
     if(shotsPerClip>0&&!runOnce){
       InvokeRepeating("ShootGun", 0, timeBetweenShots);
       runOnce=true;
     }
   }else{
     CancelInvoke();
     runOnce=false;
   }
}

public void ShootGun(){
  //do all shooting functions
  if(shotsPerClip<=0){
    CancelInvoke();
    //call reload function
  }
}

Look at this:

Gives you the actual firing code too.

Hey thanks!
