Is there a way to make an image show up on the screen in a 3D game? I tried creating a sprite and positioning it at (20, 20) so that it would always show in the top left corner of the screen, but it's not showing up. Thanks.

Hey Scott,

Without seeing code I can only guess that there is a problem with the image you're loading. Make sure the path is correct (in case you have it in a subfolder for example).

Sprites are considered 3D by the engine and by default are drawn last. So, barring problems with the images not loading, they should appear on top of everything else. They also have no need of being re-applied each frame. They handle it themselves.

Hope this helps,

-Frank

This is what I have so far:



I know the path is right since I managed to get the image to be textured on an object. Do I have to do something with dbGetImage, and if so, what do I do? The dimensions of the image is 76 by 76, and I tried (0, 0, 76, 76) and (0, 0, 75, 75) as parameters to dbGetImage but each time I got an error. Thanks.

If you're able to use the image then just calling dbSprite() as you have should do it. You're not calling dbDrawSpritesFirst() by any chance are you?

Another thing I just thought of would involve the currently active bitmap. Bitmap 0 is the screen. If you use dbLoadBitmap() or dbCreateBitmap() it will change the active bitmap so you won't be able to see things being rendered.

Either way, I've attached a very simple project that displays 2 sprites while rotating a cube. Hopefully it'll help answer your questions.

Ahh I figured it out, I was using a constant for the sprite and for some reason I had assigned it to 0 instead of 1, oops. Thanks for the help!
