sprite and color... in b&w color....

[mousam59]

hello,
i have a question about the sprite.
when you made a sprite, there was 0 or 1 for color... 1 for black and 0 is transparent .... but if i want to made a big sprite with space in it, when it was displayed we could see the background.... then i think about a mask... display the background, so the mask to erase the portion of background where my hero is draw and at last display onto the mask my hero..... how could i make that?????????
for example, i have a old gameboy in B&W, castlevania, the background was plenty of texture, and the hero had a white line around it to clarify the game, this is that sort of technique that i want to make..... but if i made a mask with 1 for white, gb will display a black..... and if i want to the all screen was black and my sprite white?????
i'll expect everybody understand...
thank's
bye.

The default colors for the graphical function are black foreground and transparent background. You can change it using gb.display.setColor(foreground, background).

In your case you can create a bitmap containing the white outline of your character and then do something like that:

Code: Select all

gb.display.setColor(WHITE);
gb.display.drawBitmap(characterMask);
gb.display.setColor(BLACK);
gb.display.drawBitmap(characterBitmap);
