Some issues with firing weapons

Unity Engine
1

Hello, all! Yes, it’s me again, back regarding issues with my project.

I’m trying to use this slightly altered version of the Rocketlauncher script from the FPS tutorial to make a spaceship gun that does not use ammo, but has a reload time. The problem is that it isn’t instantiating my projectile object when I click the Fire1 button (left ctrl/mouse 0).

Any and all help would be appreciated.

var projectile : Rigidbody; 
var initialSpeed = 20.0; 
var reloadTime = 0.5; 
private var lastShot = -10.0; 

function Fire1 () 
{ 
 // Did the time exceed the reload time? 
	

 if (Time.time > reloadTime + lastShot) 
 
 { 
 	
 // create a new projectile, use the same position and rotation as the 
 // Launcher. 

 var instantiatedProjectile : Rigidbody = Instantiate (projectile, transform.position, transform.rotation); 
 
 // Give it an initial forward velocity. The direction is along the z-axis of 
 // the missile launcher's transform. 
 instantiatedProjectile.velocity = transform.TransformDirection(Vector3 (0, 0, initialSpeed)); 
 
 // Ignore collisions between the missile and the character controller 
 Physics.IgnoreCollision(instantiatedProjectile.collider, transform.root.collider); 
 lastShot = Time.time; 
 } 
}

Assuming that’s the entire script, you’re not checking for input. You’d need to check Input.GetButtonDown(“Fire1”) in an Update function.

Well, a quick edit later I have this, which appears to work. Thanks, Eric!

var projectile : Rigidbody; 
var initialSpeed = 20.0; 
var reloadTime = 0.5; 
private var lastShot = -10.0; 

function Update () {
    // Ctrl was pressed, launch a projectile
    if (Input.GetButtonDown("Fire1")){ 
    	FireGun ();
    }
}
function FireGun () 
{ 
 // Did the time exceed the reload time? 
	
 if (Time.time > reloadTime + lastShot) 
 
 { 
 	
 // create a new projectile, use the same position and rotation as the 
 // Launcher. 

 var instantiatedProjectile : Rigidbody = Instantiate (projectile, transform.position, transform.rotation); 
 
 // Give it an initial forward velocity. The direction is along the z-axis of 
 // the missile launcher's transform. 
 instantiatedProjectile.velocity = transform.TransformDirection(Vector3 (0, 0, initialSpeed)); 
 
 // Ignore collisions between the missile and the character controller 
 Physics.IgnoreCollision(instantiatedProjectile.collider, transform.root.collider); 
 
 lastShot = Time.time; 
 } 
}
