enemy shooting towards FPS [closed]

Question

WELL first of all I want you to see my game (its deployed on heroku cloud) :

http://still-escarpment-3701.herokuapp.com

(It takes almost 10 sec to load so please wait for couple of sec)

I have successfully implemented fps shooting .but same logic are not working for enemy to fps shooting ..:(

THE PROBLEM IS THAT :

Bullets gets saturated just after the shooting function is called ..i need enemy to shoot the bullets after some suitable delay just like its happening with fps shooting ...

       bulletTempEnemy = new J3D.Transform();

       bulletTempEnemy.geometry = J3D.Primitive.Sphere(0.5, 4, 4);
       bulletTempEnemy.renderer = J3D.BuiltinShaders.fetch("Normal2Color");

       bulletHolderEnemy = new J3D.Transform();

    engine.scene.add(bulletHolderEnemy);



function EnemyShooting(){

     bulletHolderEnemy.position.x =swat2.position.x;
     bulletHolderEnemy.position.y =swat2.position.y;
     bulletHolderEnemy.position.z =swat2.position.z;

    var b = bulletTempEnemy.clone();

var f =v3.sub(first_person_controller.position,swat2.position).norm();
b.direction = new v3(); 
b.direction=f;

    b.position.fromArray(f);
    b.progress = 0;
    b.ttl = 50;

    b.animate = function() {
    b.position = b.direction.cp().mult(1 + b.progress);
    b.progress += 1;
    b.ttl--;            

                if(b.ttl == 0) {
                    bulletHolderEnemy.remove(b);
                                 }
            }

            bulletHolderEnemy.add(b);

}

and then code below was called in the game loop function draw()

 var zdis= Math.abs(Math.abs(Math.abs(swat2.position.z) -  Math.abs(first_person_controller.position.z)));
 var xdis= Math.abs(Math.abs(Math.abs(swat2.position.x) - Math.abs(first_person_controller.position.x)));


if(xdis < 80)
{
setInterval(EnemyShooting(), 90000);

}



   for(var i = 0; i < bulletHolderEnemy.numChildren; i++) {
   bulletHolderEnemy.childAt(i).animate();
  }

library used :J3D (https://github.com/drojdjou/J3D)

any help would be appreciated to resolve this saturation probLem of shooting bullets ....:|

Answer 1

Something that I have used for delays: Have a counter that increments by dt each frame. If it is above the required delay, don't continue to increment it. Then, if it is above the required delay AND the firing condition is true, have it fire the bullet and set the counter back to zero.

Pseudo-code here (in game loop):

if (firingcounter <= firingdelay){
    firingcounter += dt
}
if (firebulletcondition == true and firingcounter > firingdelay){
    firebullet()
    firingcounter = 0
}

Answer 2

thankx alot garan my problem is resolved :)

var firingdelay=1000;

var dt=50;

if (xdis < 80 && firingcounter > firingdelay){ EnemyShooting(); firingcounter = 0 }

if (firingcounter <= firingdelay){ firingcounter += dt }
