Firing Cooler

Questions & Answers
1

Hi, I tried to make a fire cooler, in which my hand gun shoots, the animation work, the raycast works, then it has to cool off for 0.5 seconds in order to re-fire. So I tried the following. I created a variable that is similar to my rate of fire and called it "ShootCooler, and then set it equal to each other after the fire function. But that didn’t work. Here is my code without my trials:

NextFireAt = Time.time;
var Spawn : Transform;
var BulletSpeed : float = 1000;
var ReloadTime : float = 1;
var AmmoInMag : float = 7;
var IsFullAuto = true;
static var AmmoLeft = 0;
static var ReloadTTime : float;
static var IsReloading = false;
private var CanFire = true;
var FireRate = 0.3;
var range = 100;
var DirtImpact : Transform;
var ConcImpact : Transform;
var WoodImpact : Transform;
var BulletBulletHole : Transform;
var WaterImpact : Transform;
var MetalImpact : Transform;
var BloodImpact : Transform;
private var NextFireAt : float = -1;


function Start () {
 AmmoLeft = AmmoInMag;
 ReloadTTime = ReloadTime;

}

function Update (){
 if(IsReloading) return;
 if(Time.time >= NextFireAt)

 if (Input.GetKeyDown(KeyCode.R))
 {
 BroadcastMessage("ReloadAnim");
 Reload(); 
 }

 if(IsFullAuto == false){
 if(Input. GetButtonDown("Fire1")){
 if(AmmoLeft > 0){
 BroadcastMessage("FireAnim");
 Fire();
 } 
 }
 }
 else{
 if(Input. GetButton("Fire1")){
 if(AmmoLeft > 0){
 BroadcastMessage("FireAnim");
 Fire();
 
 } 
 }
 }
 
 if(AmmoLeft == 0)
 {
 Reload();
 }
 
 if(AmmoLeft < 0){
 AmmoLeft = 0; 
 }
 
}

function Fire(){

 if(CanFire == true && IsReloading == false){
 
 var hit : RaycastHit;
 var fwd = Spawn.TransformDirection(Vector3.forward);
 Debug.DrawRay(Spawn.position, fwd);
 
 CanFire = false;
 yield WaitForSeconds(FireRate);
 CanFire = true;
 AmmoLeft -= 1;
 audio.Play();
 
 if(Physics.Raycast(Spawn.position,fwd,hit,range)){
  var hitTag = hit.collider.tag;
  var pos = hit.point+0.01*hit.normal; 
  var rot = Quaternion.FromToRotation(Vector3.forward, hit.normal);
  if(hitTag == "Dirt"){
   Instantiate(DirtImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
  }
  if(hitTag == "Concrete"){
   Instantiate(ConcImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
   }
   
  if(hitTag == "Wood"){
   Instantiate(WoodImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
   }
  if(hitTag == "Water"){
   Instantiate(WaterImpact,pos,rot);
   }
  if(hitTag == "Metal"){
   Instantiate(MetalImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
   } 
    if(hitTag == "Blood"){
   Instantiate(BloodImpact,pos,rot);
   } 
 }
 }
}

function Reload(){
 CanFire = false;
 IsReloading = true;
 BroadcastMessage("ReloadAnim");
 yield WaitForSeconds (ReloadTime);
 IsReloading = false;
 CanFire = true;
 AmmoLeft = AmmoInMag;
}

seems to me that’s already handled in this script… in the Fire function, with

if(CanFire && !IsReloading) 

..(you don't need the "== true")

the value of the var FireRate would determine the rate of fire..

EDIT___________

The fire function only gets entered once every .3 seconds, due to the FireRate…
If you move the lines

yield WaitForSeconds(FireRate);
 CanFire = true;

to the end, and put all your animation, sound, etc. calls above that, It will all only be called once every .3 seconds (or whatever the rate is set to)… isn’t “Rate of fire” and “cool down time” the same thing?

as it stands now, the FireRate regulates both the cool down time between shots, AND the time it takes the bullet to reach its target… so if that’s what you intended, you could just add a second yield:

function Fire(){

 if(CanFire && !IsReloading){

 var hit : RaycastHit;
 var fwd = Spawn.TransformDirection(Vector3.forward);
 Debug.DrawRay(Spawn.position, fwd);

 CanFire = false;

//initial animation code,sound etc. probably goes here

 //if you wanted a delay before bullet hits, otherwise move next line to bottom
 //yield WaitForSeconds(FireRate);
//This is what caused the delay, because it comes before the raycast etc.

 AmmoLeft -= 1;
 audio.Play();

 if(Physics.Raycast(Spawn.position,fwd,hit,range)){
  var hitTag = hit.collider.tag;
  var pos = hit.point+0.01*hit.normal; 
  var rot = Quaternion.FromToRotation(Vector3.forward, hit.normal);
  if(hitTag == "Dirt"){
   Instantiate(DirtImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
  }
  if(hitTag == "Concrete"){
   Instantiate(ConcImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
   }

  if(hitTag == "Wood"){
   Instantiate(WoodImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
   }
  if(hitTag == "Water"){
   Instantiate(WaterImpact,pos,rot);
   }
  if(hitTag == "Metal"){
   Instantiate(MetalImpact,pos,rot);
   Instantiate(BulletBulletHole,pos,rot);
   } 
    if(hitTag == "Blood"){
   Instantiate(BloodImpact,pos,rot);
   } 
 }
  //could have "cool down code" here, if you need..
    yield WaitForSeconds(coolDownRate);
    CanFire = true;
 }
}
