Switch enum case on key pressed

Questions & Answers

Good day.
I’m making a FPS game so I’m trying to make fireMode for weapons (semi, burst, auto)
And I want to change my fireMode each time I press Input.GetKeyDown(KeyCode.V)
here is what I have

public class shoot : MonoBehaviour {

// a lot of variables

	//fire mode
	public enum FireMode
	{
		semi,
		burst,
		auto
	}
	public FireMode fireMode;

void Update(){
	switch (fireMode) {
			case FireMode.semi:
				if (Input.GetMouseButtonDown (0)) {
					ProjectileCount = 1;
					TryFire ();	
				}
				break;
			case FireMode.burst:
				if (Input.GetMouseButtonDown (0)) {
					ProjectileCount = 3;
					TryFire ();	
				}
				break;
			case FireMode.auto:
				if (Input.GetMouseButton (0)) {
					ProjectileCount = 1;
					TryFire ();	
				}
				break;
			}
}

It is working fine when I set FireMode in Editor
But I don’t know how to make it change in runtime when pressing a key.
thanks

Hi,

an enum is, under the hood, an int. So you can do the following :

if (Input.GetKeyUp (KeyCode.V))
{
	int currentFireMode = (int)fireMode;
	currentFireMode = currentFireMode == 2 ? 0 : currentFireMode+1; // replace 2 with the greater
	fireMode = (FireMode)currentFireMode;
}

I would also add that you can optimise your switch case logic, by first checking if (Input.GetMouseButtonDown (0)), then use the switch as it seems you’re always using the same mouse button.

if (Input.GetMouseButtonDown (0))
{
	switch (fireMode)
	{
		case FireMode.semi:
			break;
		case FireMode.burst:
			break;
		case FireMode.auto:
			break;
	}
}
