ok well i'm redoing my map editor and it was telling me bitmap to small to get image (idk why) so i tried making a large 2nd bitmap and using set current bitmap(should fix it and get a little farther so i can see wats going wrong) but its telling me unknown command and the syntax highlighting is highlighting it so its spelled correctly. it did this before but stopped any ideas?

+ Code Snippet

Load_Tiles:
   create bitmap 1,1000,1000
[b]   set current bitmap 1[/b]
   Load image "Tiles1.bmp",100
   Sprite 1000,-1000,-1000,100
   TW=Sprite width(1000)
   TH=Sprite height(1000)
   delete sprite 1000
   Colums=Tw/32
   Rows=TH/32
   cls
   Print Colums
   Print Rows
   paste image 100,0,0
   For Y=0 to rows
      for X=0 to colums
         img=img+1
         print X
         print y
         get image img+10,X*32,Y*32,(X+1)*32,(Y+1)*32
         numtiles=numtiles+1
         timage(img)=img+10
      next x
   next y
   set current bitmap 0

Return

if you want the rest tell me but this is where its giving problems

Bitmap too small to get image means you are trying to get an image that is larger than the bitmaps size (not a problem on bitmap 0, but only on others).

This is the most LIKELY reason:

You created a bitmap, lets say, at 640x480

You then tried to grab the screen by 0,0,640,480

The problem is that 640 is number of pixels wide, and if it starts counting from 0, then to get 640 pixels, it has to be from 0 to 639 (get it?)

That is my guess, though I haven't looked into the code much yet.

[EDIT] BN2 beat me to it!

[ORIGINAL]
How big is the Tiles1.bmp? You may be over reaching unwittingly.

An alternative to loading the image and turning it into a sprite might be:

+ Code Snippet

Load_Tiles:
   rem create the oggscreen bitmap automatically to the image size
   load bitmap "Tiles1.bmp",1
   set current bitmap 1
   TW=bitmap width(1)
   TH=bitmap height(1)
   rem if there were 10 rows or columns calculated, the
   rem first position would be 0, the last would be 9
   Columns=(TW/32)-1
   Rows=(TH/32)-1
   For Y=0 to rows
      for X=0 to colums
         img=img+1
         print X
         print y
         get image img+10,X*32,Y*32,(X+1)*32,(Y+1)*32
         numtiles=numtiles+1
         timage(img)=img+10
      next x
   next y
   set current bitmap 0

Return

Enjoy your day.

BN2:

It was giving a bitmap to small to get image before i made another bitmap. and you can still get that error with bitmap 0 can't you?
bitmap 0 is the size of the screen (640,480) so if its bigger then that you with run into the problem of bitmap to small to get image won't you? thats why i don't know why i'm getting this error. the image isn't that big

but i see what you mean

Latch:

interesting idea i forgot about load bitmap lol. the image is 128 by 96 so it shouldn't be making this error lol its 32X32 tiles 4X3 lol thats why i was trying to get past it and find the error in the calculations.

although i don't know why its that size as 32*4 is 136 and 32*3 is 102 hmmmm i made it in paint heres the image.

i will try that though latch thanks to both of you

Your loops reached beyond the size of the bitmap. If you check the code I supplied, I reduced the size of your loops. You loops were 1 unit too long. If your tile ratio is 4x3, because you start counting from 0, then rows should be 3-1 and columns should be 4-1

+ Code Snippet

   Columns=(TW/32)-1
   Rows=(TH/32)-1
   For Y=0 to rows
      for X=0 to colums
         img=img+1
         print X
         print y
         get image img+10,X*32,Y*32,(X+1)*32,(Y+1)*32
         numtiles=numtiles+1
         timage(img)=img+10
      next x
   next y

Enjoy your day.
