In DBC, I used plains locked to the screen for a HUD, in DB Pro the same code just doesn't work. Is there a different technique required in Pro?

Here's the routines I used, they are from the Binary Moon tutorials...

To expand on this issue, If I use sprites I get a maximum 5 fps! I know that sprites are theoretically just plains, but something else goes horribly wrong when I use them.

backsace off speeds it back up again, but the image is corrupted...any idea why it gets corrupted, even when the sprite is static? It becomes a blur of black and white lines.

Finally sorted it...

Backsave set off, Texture loaded with Mipmapping set on...works like a dream. I had switched Mipmapping off, thinking that it was redundant because the sprite would always be the same distance from the camera...wrong diddly wrong wrong!

The backsave I guess is not needed because in a 3D environment there is always an object behind it which will keep the screen "clean"

Here's some of the code I've used. In the end it was very simple, it was just a case of getting the right combination of parameter settings. It seems a shame that all my hard work and struggles resulted in just 3 lines of code for each HUD element!

I was also told by someone that ghosting sprites causes problems with ghosted objects behind them, so I created all my graphics as PNGs and set my own transparency directly in the image.



I change the HUD sprites every Nth cycle, there's no need to update it 40 times a second, or whatever speed the game's running at.
