Hello again gentlemen. With pxl-change, lets say:
:For(Y,1,3
:For(X,1,5
:Pxl-Change(Y,X
:End:End
Now when this happens, of course, the pixels change, but they change to slowly for me. So in two questions: Is there a way for pxl-change to occur faster or is there a way to instantly change pixels the second the graphscreen is displayed? |

Code:
For(X,1,5
PxlChange(X,1
PxlChange(X,2
PxlChange(X,3
End
OR
Code:
For(Y,1,3
PxlChange(1,Y
PxlChange(2,Y
PxlChange(3,Y
PxlChange(4,Y
PxlChange(5,Y
End
I think the last one would be the fastest.

 Thanks yugniht, while we're still on the topic of fast, is there a another way I could substitute X instead of a number to increase by 1 from 15 to 50? |

| yea, but thats the problem. Whenever I use the For(X like that, the pxl-change is way to slow |

im not sure, but u might try:
Code:
15->X
Repeat X=50
Pxl-Change, blah, blah
X+1->X
End
it might be faster cuz i find repeats and whiles to be generally faster than fors, but i may be wrong. |

well, first of all, it is Pt-Change, pxl-Change would look like this :
Code:
If Pxl-Test(X,Y:Then:PxlOff(X,Y:Else:PxlOn(X,Y:End
just thought id clear that up right away 
now, i dont know if using repeat would be faster, but i would guess so, did u try it yet? tell us the results plz! |

Huh? Why not just use pxl-change? That seems like it would be longer.

| Yes you are correct Jeffery. A routine such as Adm. Wiggin's takes even longer than a For( loop. One of the best ways to change pixels' fast is to use asm... |

| Adm. Wiggin: you made a mistake, you said Quote: PxlChange(X,Y When it's Quote: PxlChange(Y,X
You probably knew but didn't think about it. |

| Ummm.... JesusFreak. That only turns the lines on or off not inverting them. |

| No. Pxl-Change( inverts a pixel. If it is black it becomes white, or vice versa. |

| all is does is if it is on, turns it off, if off turns it on, so if he wanted a whole line "white" that is all black he can do my thing which is a lot faster than pxl-chg |

| Well if he had a line that half of the pixels were on and half were off that would not work. It would just turn off all of the pixels. |
