Hey all, I’ve used Invoke successfully in the past, but for a reason I just can’t figure out, it’s failing on my enableInput function. I’ve searched for this exception and as far as I can tell, it has only cropped up when someone passed a misspelled method name to Invoke or tried to use it with a coroutine. I’m not familiar with coroutines, but I suppose that neither of those conditions apply in this case. Here are (what I consider to be) the relevant snippets of InputController.cs:
public void disableInput(float timer = 0)
{
inputAllowed = false;
if (timer > 0)
{
Invoke ("enableInput", timer);
}
}
public void enableInput(float timer = 0)
{
inputAllowed = true;
if (timer > 0)
{
Invoke ("disableInput", timer);
}
}
void Update () {
...
if (mouseLeftClicked == true) {
...
disableInput (.2f);
}
...
}
When I run the game and click, disableInput(.2f) gets called and the program enters the disableInput method with timer > 0. When it tried to execute the Invoke line, it throws this exception:
Trying to Invoke method: InputController.enableInput couldn't be called.
What’s wrong? Thank you!
P.S. Here’s the full script in case more context is needed.
