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? |

Quits as in exits, or quits as in errors out, and if the latter, what error and on which line?
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 |

hmm that seems to eliminate the need for the label as well(too used to C, there needs to a be a basic break command  ).. 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

Breaking out of for loops:
For(X,1,100
If getKey:100->X
End
For(X,1,not(getKey)100
End
etc.
Why does being too used to C explain why you use labels? If there's any language where you don't need them it's C/C++. |

I used labels cause it was the first thing that came to mind to replace break.
PS: don't be an asshole |

well this comment:

| it was a simple question wondering the reasoning behind your statement. |

I was just wondering, well, what I asked.
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.
