Hi,
For my game I need to be able to dynamically create text into an image. This can then be applied to a 3D plain. I do not want the text being shown anywhere other than the 3D plain.

At the moment I am first calling dbGetImage to get the contents of what was on the screen first. I then draw the text on the screen and then call dbGetImage again. I now have the text loaded as an image ready for texturing on the plain. However the text has just been placed on the screen so I have to paste the image of what was there before over the top of the text.

As you can see this solution isnt great for performance and bit of work around.

Is there any other way I could do this more efficiently or better?

Thanks,
Alex

Use bitmap 1 instead of bitmap 0 (the screen).

dbSetCurrentBitmap(1);
<do stuff>
dbSetCurrentBitmap(0);

Is there anyway to get the bitmap slot straight into an image slot instead of having to save it to the disk first?
