How to fire two bullets instead of one?

Hi

I have a script that fires a prjectile in my game but i want it to fire two, each after a short delay.

I’m not sure what code i need to add to make it fire twice.

It is part of a powerup script:

	if (hasMachineGun) {
				GameObject cloneMachineGun;
				Vector3 fireMachineGun = transform.forward * projectileSpeed;
				
				if(Input.GetButtonDown("Fire1")){
					cloneMachineGun = (GameObject)Instantiate(machineGun, machineGunSocket.transform.position, transform.rotation);
					cloneMachineGun.rigidbody.AddForce(fireMachineGun);
					
					playerState = PlayerState.CarNormal;
					changeState = true;
				}
			}

I think that is all thats needed?

Thanks

I’m not 100% sure how your code works but you can fire twice or x-amount of times using for-loop.

if (hasMachineGun) {
	GameObject cloneMachineGun;
	Vector3 fireMachineGun = transform.forward * projectileSpeed;
	
	if(Input.GetButtonDown("Fire1")){
		for (int i = 0; i < 2; i++){	// Fire twice.
			cloneMachineGun = (GameObject)Instantiate(machineGun, machineGunSocket.transform.position, transform.rotation);
			cloneMachineGun.rigidbody.AddForce(fireMachineGun);
		}
		
		playerState = PlayerState.CarNormal;
		changeState = true;
	}
}

Adding delay is a little more complicated thing. You could use invoke or coroutine. In both cases you have to make function for firing.
I made a coroutine example for you, but you should definitely check how they work:
http://unity3d.com/learn/tutorials/modules/intermediate/scripting/coroutines

	if (hasMachineGun) {

		
		if(Input.GetButtonDown("Fire1")){

			StartCoroutine(FireMachineGun());

			playerState = PlayerState.CarNormal;
			changeState = true;
		}
	}

float fireDelay = 0.2f; // Delay before both shots

IEnumerator FireMachineGun()
{
	GameObject cloneMachineGun;
	Vector3 fireMachineGun = transform.forward * projectileSpeed;

	for (int i = 0; i < 2; i++){
		yield return new WaitForSeconds(fireDelay);

		cloneMachineGun = (GameObject)Instantiate(machineGun, machineGunSocket.transform.position, transform.rotation);
		cloneMachineGun.rigidbody.AddForce(fireMachineGun);
	}
}
