You shouldn't be using the normal getkey for games.  Its slow and it returns funky stuff sometimes.  That code should be:

Code: [Select]
Pause 50
X+getKey(3)-getKey(2)->X

I'm using it to get input for the user to type their name, so I don't want a lot of statements.  I pretty much need getKey to use with my look up table.
Nemo, I'm using it the second way.  Still no luck. =(

quigibo, the BASIC way of getkey functions better for a menu. at least, for me it does. with yours it has the possibility of skipping an item. and if i increase the pause, my menu just looks like it's responding ridiculously slow.

sorry ztrumpet  :-\ i don't have anything else, except maybe quigibo's way will work. i suggest upping the pause to about 200-250 though, since 50 you have to deliberately try to not skip the middle item(s) in your menu

EDIT: offtopic, quigibo, are sine, cosine and the signed division routine really slow or did i accidentally put a delay in my program?

Yeah, I wasn't sure if this was for a menu or part of the game.  Regular getkey is definitely good for menus.

Signed division is definitely the slowest of the 3.  The reason the circle looks a little square-ish is that I'm using a very fast approximation of sine and cosine for performance reasons.  Normally you don't notice it at all unless you draw the trail of the sprite.

 :-\ alright. i'm only doing two signed divisions, two sines and two cosines and that section of my program is already as slow as the other which calls a subroutine 6 times for tilemap collision detection, and then has a volley of if statements to determine what to do. if there's any way to improve the signed division routine, that would be excellent. seeing as i don't even know what parsing actually does, i'm not exactly in a position to talk

I've confirmed that adding
Output(6)
Disp B>Dec
right after the getKey always returns a zero. :(

You didn't disable intterupts did you?  They are required for getkey.

interrupts? Do you mean we must do FnOn at the start of our programs to be able to use getkey() now?

No, they're enabled by default.  You just shouldn't call fnOff without enabling it again if you plan to use OS getkey

Oh ok. By OS getkey you mean getkey without the (), right?

There are no FnOffs in the program. :(

Could you maybe post your code via Quigibo PMs in case this might be a bug?

The code's in the first post, in program form.  To clarify, this is NOT a contest entry. :)
