I'm making an RPG where you can customize your character. Hair, eyes and etc... and i want a "Colorize mode" Can anyone explain me how do i use the palette plz?

I don't speak english, but this is the only good community i've found that supports DX7 too

If I were doing this, I wouldn't use palettes. I would do one of two things:

1. If my graphics were cell shaded, I'd do a pixel by pixel recolouring of those cell colours, replacing an old RGB value with the desired RGB value.

2. If my graphics were not cell shaded, I'd apply a lighting effect across the image such as subtracting from or multiplying the RGB of each pixel by the same figure.

eg, (red,grn,blu) --> (mred*red , mgrn*grn , mblu*blu)
or
(red,grn,blu) --> (-mred+red , -mgrn+grn , -mblu+blu)


However, you say you're using DX7. I believe that provides some lighting effects, which you could use to change the appearance of graphics. But I don't know much about DX.

It's cell shaded, but the surface is very large, i can't do this for every player in the game. :/

okay. It doesn't have to be recoloured every time those graphics are redrawn. You have the option of preparing the recoloured graphics as a character is created. Would that be quick enough? Or would it sap too much memory?

Too much memory. If i do this, i have to save the surface in the memory, but the surface image is 256*8192, if i have 3 pg i have to save this 3 times and recolour it 3 times :/

then you need to use palettes

(I don't know how)

Nothing... I think palette-system is impossibile on directx7

If you're running in 256 colour mode, directdraw does use a palette, but you may not be able to draw with palette mapping. Directdraw was left in an incomplete state when 3d took over the world.

So...

How many characters are going to be on screen at once? Because you could reserve some of the palette for hair/eye colours, and have just two or three colour variations loaded into video memory.

You would adjust the global palette to change the colour of these features depending on what characters were on screen.

On www.directx4vb.vbgamer.com it works!!
Look: http://directx4vb.vbgamer.com/DirectX4V ... lettes.asp

i follow the code, and i do it on my game and it doesn't work .-.

What do you get when you try it?

If it's applying a palette to a surface, then what is being copied from that surface to your screen buffer ?

Is it full rgb or does it remain as a paletted bitmap. Because if it's paletted then won't the palette of the screen buffer will be applied to it? overriding whatever palette you applied intermediately?

Error Number : 8876023C ( -2005532100 )
Error Code : DDERR_NOPALETTEATTACHED
Description : No palette object attached to this surface.

I get this error and my game closes..

I can only make guesses. Maybe this?

-- Surfaces must be created before palettes can be applied to them.

-- Palettes must be created before they can be attached to a surface.

Try disabling certain lines starting from the bottom. Narrow it down to one which causes this error.

This is my code if everything it's allright, i must see the surface colored in black..

Ok, i've found...
To let the palette works you need to set the gamescreen to Fullscreen and 8-bit mode. Or it doesn't work...
