 Posted: 06 Mar 2004 11:57:27 pm    Post subject: hey ppl been a while since I went to cirrus(2002 I do believe was the last time), and I thought it was about time I went back and did a few things that I was doing years ago(lol 2 years). But to my demise I ran into a problem in my simple game test program. Now down to the problem. What happens is when repeated input is in the game, it quits the game, what I'm wondering is way to prevent this.. here's the code to the game Code: ```0üXmin 0üYmin 94üXmax 62üYmax AxesOff CoordOff ClrDraw 0üÁ 28üA 28üB 31üZ 47üT 1üU Line(1,A,1,A+5) Line(93,B,93,B+5) Line(0,0,94,0) Line(0,62,94,62) 1üV While Á=0 0üK For(J,0,5) getKeyüK If Kø0 Goto 1 End Lbl 1 If K=25 Then Pt-Off(93,B) B+1üB Pt-On(93,B+5) End If K=34 Then Pt-Off(93,B+5) B-1üB Pt-On(93,B) End If K=21 Then Pt-Off(1,A) A+1üA Pt-On(1,A+5) End If K=31 Then Pt-Off(1,A+5) A-1üA Pt-On(1,A) End If K=45 1üÁ pxl-Test(Z,T+U)üR If R=1 úUüU pxl-Test(Z+V,T)üR If R=1 úVüV Pt-Off(T,Z) T+UüT Z+VüZ If T>93 or T<1 47üT Pt-On(T,Z) End``` (or you can get it from http://eedok.voidofmind.com/game/PONG.8xp alternatively) does anyone experienced in the realm of the 83+ know what's causing the problem and how to prevent it?

This: 0üK For(J,0,5) getKeyüK If Kø0 Goto 1 End Lbl 1 seems pointless to me since it's going to Lbl 1 whether or not the If line is true or false, and having that in the For loop only opens you up to a memory leak. I can see what you're trying to do there, perhaps a better way would be 0üK For(J,0,5) If K=0 getKeyüK End Lbl 1

The unmatched end from the goto seems like it may be the problem, I'll test it out as soon as I can get my calculator back thanks Last edited by Guest on 07 Mar 2004 10:26:10 pm; edited 1 time in total

I've never used labels in C/C++ so that got me curious as to why you did, maybe they where usefull after all, or maybe you thought they where the only way to control program flow. In that case people could help you by informing you on other methods and such. Sorry if you felt offended by that.Last edited by Guest on 09 Mar 2004 07:35:20 am; edited 1 time in total
