Switch enum case on key pressed
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;
}
}
