Greyscale Pictures
« on: February 08, 2011, 11:58:37 pm »
I am a noob at Axe Parser, and would like some advice regarding greyscale pictures. I have done the following code:
Code: [Select]
.EVERYDAY the Same Dream
ClrDraw

GetCalc("appvSC",1*1536)→P

GetCalc("appvSC")→P
Copy(P,L₆,768)
Copy(P+768,L₃,768)
Repeat getKey(15)
DispGraphr
End

The place where the problem is is marked. Can somebody please examine this code and tell me what is going wrong? The error is "bad number". The hex was created using sourcecoder with a 96*31 picture with 3 greyscale colors.

Ah, I am not sure, but does all of the hex need to be on one line? Like, instead of:
Code: [Select]
...
FF80200FFFFFFFFBF402007F
FF80200FFFFFFFFBF402007F
...
put all the hex on one line:
Code: [Select]
...FF80200FFFFFFFFBF402007FFF80200FFFFFFFFBF402007F...

Why are you copying only 720 bytes?

Such arrays are stored in a different way in axe, you might want to look at this:

Code: (Axe) [Select]
[FFFF->Pic1
[FFFF
[FFFF
[FFFF
[0000->Pic0
[0000
[0000
[0000

He's only copying 720 bytes since his picture doesn't take up the whole screen (What are the dimensions of your pic btw? If the length is less than 96 it could get a little messy)
Anyway, if you want to put the pic data into the appvar, you'd have to do something like...
Code: [Select]
GetCalc("appvSC",1536)->P
Copy([Hex],P,720*2)
Copy(P,L6,720)
Copy(P+720,L3,720)
Repeat getKey(15)
Dispgraphr
EndBut there's not really a point to putting it into an appvar anyway since it's stored in the program...so
Code: [Select]
[Hex]->Pic1
Copy(Pic1,L6,720)
Copy(Pic1+720,L3,720)
Repeat getKey(15)
Dispgraphr
End

These pictures are 96*31. I have figured out, since the actual image is fine, it's just the area it doesn't cover that glitches, that I can just put a black rectangle where the glitches are.

By the way, is there a fast way to display a non 96*64 picture on a different part of the screen?

You could try sprites but I do not know if Axe can make odd sized pictures.

Is there a way to have sprites simply go on top of the background, and not disturb the background itself? In BASIC, you always had to compensate the sprite's movement by replacing the pixels behind it. Does Axe have a simpler way? Or is it the same as BASIC, and will I have to reload the background back onto the screen every time my sprite moves?

By the way, the sprite is greyscale.

The sprite automatically overwrites the background, I think, unless you choose some other logic method. And you will need to reload the image, I think.

By any chance, does pressing [2ND] for the first time end the program?
If so, then adding a
Code: [Select]
While getKey(0)
    DispGraphr
End
after your first Repeat loop might help.

Thanks. I forgot that Axe is 9001% faster than BASIC. =)
