There may have already been a topic like this one. If so, please send me the link.

I'm sure everyone has noticed that when you press any of the arrow keys in a game, the program keeps sensing that it is pressed and GetKey senses the input. If you havent read in the other forum, DEL and the arrow keys are the only keys that do this. You may have also noticed that it waits a little while after the first press to continuously sense that key. Here's an example of what is going on during a game:

-No movement
-User presses and holds right arrow key
-Object on screen moves right
-No movement*
-No movement*
-No movement*
-Object on screen moves right
-Object on screen moves right
-Object on screen moves right
-Object on screen moves right
-User lets go of right arrow key
-No movement

You get idea. So after the user presses and holds the key the first time, why does it take a few loops of the program (*) to continuously move right? Does anyone know any way to prevent this so it responds right away???

Why it does that? I guess it's just TI's way of making sure you meant to do that; some calculators are "looser" than others btw (their arrows move faster). How to fix it? Use ASM's getkey.

I thought you might say that. I'm so frusterated with BASIC, I guess that's the next step. Too bad it's almost impossible on a Mac.

Lol sorry, i'm TI-Basic all the way myself, ASM's too complicated for my feeble mind right now.

You could email someone so they would assemble a program for you...

I have another question kinda like the original.... is there anyway to input 2 key presses at once? Like press up and right at the same time and actually have the program sense that they are both pressed?

Sorry, ASM again. If you asked someone veeeeeeeeery nicely, they might write you a program that returns two keys. I think Jbirk was thinking along the lines of 21.105 for 2nd Enter, and you could use fpart( and Ipart( to get the two key presses.

Jup, better ask in the asm forum if anybody has such a routine ready or is willing to write one for oyu.

24.25 + 26.34i. That'll give you 4 keys.

Or a program that waits for key input, then returns the asm getkey result in Ans.
