I thought of a game where you would press a key a special amount of times as fast as possible. Faster clicks = more points. Each time you press said key, it plays a new animation, and it isn't unlimited, therefor there has to be some sort of timer that ticks down.
My idea is that you have the timer, and you have a specified amount of base points, then you multiply the remaining time with the base points.
So how are we going to do all this?
//Timer (counts down from... Say 7 seconds)
...
7-A->B (A is the time it took)
100*B->C
Output(y,x,"You scored: ")
Output(y+1,x,C)
Only thing missing is the timer now. *Also, I'm using the TI-82, if I'm correct it doesn't have a built in timer function.
Question is if it's possible to have a timer working in the background of the clicking process.
