Question on greyscale

[Deathsting]

Whats the syntax for gsFlipHoriz? Is it

Code: Select all

Ld ix,some
call gsFlipHoriz

Are the greyscale sprites ORed, Do they invert when placed over a black backround?

[Duck]

The routine horizontally flips the sprite in gsTempSprite. So to flip a sprite in HL, you could:

Code: Select all

    ld hl,yourSprite
    ld de,gsTempSprite
   ld bc,16
   ldir
    call gsFlipHoriz

Is there a way i can mask the lighter grey shade instead of the darker one

[Guest]

How can i write in light and dark greysclae ???

Writting a certain chade of grayscale is as simple as setting a bit in the appropriate buffer(s).

Deathsting, you could achieve that by modifying the sprite routine a little.
