Hi all:

I'm trying to write a simple tile engine. For some reason all I get is a blank screen with this code. The wierd thing is when I debug it it doesnt step through the for loops. This is the first time I've worked with dark basic so I dont know how the debugger is supposed to work. Can anyone help me out?

Comment out the get image commands, your telling the program to get image data from the blank screen and overwrite the images that you have loaded.

disp(t,r)=rnd(5)

This generates numbers from 0 to 5, IIRC. Try:

disp(t,r)=rnd(4)+1

Also, the sprite commands create sprites. Try paste image instead.
If you really want to create sprites, your sprite ID logic needs help.

Try this inside the second loop:

sprite (ti*maxdisph)+ri, ti*32, ri*32, disp(ri+1,t1+1)

That should save you the five IF statements and properly increment your sprite count.

Instead of Load Bitmap use Load Image....Then don't bother getting them at all.

Pincho,
Load image messes up the graphics of tile images when I use it. I think it's a known bug. If not hasn't anyone else experinced problems with their images when using load image instead of bitmap? My sprites and images seem to have distorted pixels when I use Load image.

Cna anyone confirm this?

I would just use LOAD IMAGE not LOAD BITMAP it always works for me. as for it messing up the graphics, are you talking about the mipmapping? if so just add a ,1 on the end of the LOAD IMAGE command (LOAD IMAGE "grass1.bmp",1,1)
but if you really want to load bitmaps then you must swith to the bitmap before you can get a image from it.

load bitmap "grass1.bmp",1
set current bitmap 1
get image 1,0,0,32,32,1
set current bitmap 0
delete bitmap 1

it is alot more work that way.

CTP

Lifes short, try to enjoy it and not take it to seriously!
