King Piccolo will make it so Then I could just flip it with some sweet, sweet matrix math. In either case, I’ll ride this wagon until the wheels fall off. Thanks to those that keep it running

Registering multiple clicks before the program updates is very bad to have it "waiting for a second click" before updating.

best method is when you want two clicks is to set a flag, WaitingForSecondClick=true;
then your program can continue updating (graphics wise, and back ground events etc. But your main gamelogic code could be paused waiting for second click. Where you detect the mouse click, if you see that WaitingForSecondClick=true;
You can then set a Flag, GotSecondClick=true; Then the piece of code that was waiting knows its had 2 clicks and can then proceed.

Even when pausing a game, you should never actually pause the main event loop. Just the piece of code that you want paused...

Another method would be to add in a small piece of code arround your get eventsarea, that stores time and position of last click, then if another click arrives in a similar position and time, you can pass that on as a double click. (or trebble if you want), or even mouse click combos.

if you want it to ignore a single click event and pass a double clcik event, then you would need to delay the event cue for a few ticks so that it can determine if that click it just recieved was actually a double click.
