Speeding up drawing

Moonshine · Post by **Moonshine** » Wed May 26, 2004 5:15 pm

In the help file, commands such as DisplayAlphaSprite(), DisplaySolidSprite(), DisplayShadowSprite(), DisplayRGBFilter() and DisplayTranslucideSprite() are all slow unless StartSpecialFX() and StopSpecialFX() are used. I was wondering if there was any way to speed up these drawing methods (alpha sprites mainly) without having to use the Start and StopSpecialFX() commands. Im trying to make a 2d engine that runs as fast as it can, any tips are welcome

Cheers

Why don't you want to use FX() commands,

The only way I can see is that you wrote your own library in c or asm

I remeber reading somewhere on these forums that there was a performance hit when using the start and stopspecialfx commands. Im still getting used to PB, maybe I was mistaken. So is there a performance hit when using the specialfx commands?

why not use Sprite3D functions ?

DirectDraw is more suited to what Im trying to achieve. On that note does anybody know how to load an image as a sprite with an alphachannel, without having to have 2 sprites? ( i.e. a normal sprite and an alpha sprite.)
