Hi shinodan, thanks for reply!
Okay, I will summarize the doubt to facilitate.
I want an event to occur only in the following condition:
Two keys are pressed down (right Ctrl + left arrow key, for example).
This event can not occur if I press down only "right Ctrl" or "left arrow key", but only if both keys were pressed down.
Say the trigger event for this condition have pressed these two buttons is that a cube was destroyed by example.
How should I do to make the event this condition occurs only have the two keys down??
I know this is basic, but I can not create this condition in any way
