During the lesson, Sam mentioned that he didn’t know a better way to connect the keycodes to the action indexes.
I am sending here a possible solution. Please, be aware that this will require you to configure the slots accordingly to your UI.
var firstSlot = KeyCode.Alpha1;
var lastSlot = KeyCode.Alpha6;
for (var i = firstSlot; i <= lastSlot; i++)
{
if (Input.GetKeyDown(i))
{
actionStore.Use(i - firstSlot, gameObject);
}
}
Using the button 0 is a special edge case, as its keycode is smaller than Alpha1. Based on that, if you want to use the button zero, I recommend add it as a separate action outside the for loop.
Hope this helps someone
