set_write_alpha_blender(3)

✨ NAME ✨

set_write_alpha_blender — bestie, this one turns on the special alpha-channel editing mode 💅 and it lives in the Allegro game programming library 🎀

🌸 SYNOPSIS 🌸

#include <allegro.h>

void set_write_alpha_blender();

🦋 DESCRIPTION 🦋

okay so listen 👑 this function flips on the special alpha-channel editing mode, and what that mode is for is drawing alpha channels right over the top of a 32-bit RGB sprite you already have, so you can turn it into an RGBA format image. glow-up era fr fr ✨

So the way it works: after you call this function, you can set the drawing mode to DRAW_MODE_TRANS and then write draw color values (0-255) onto a 32-bit image. And the vibe? The color values stay untouched — literally unchanged — but the alpha gets altered to whatever values you're writing. it's giving surgical precision, no cap 💅

and that's not even all of it 🫶 once you've enabled this mode you can also use draw_trans_sprite() to superimpose an 8-bit alpha mask over the top of an existing 32-bit sprite. mask on, sprite slayed, periodt 🌈

ngl the order matters here — call set_write_alpha_blender() first, then switch to DRAW_MODE_TRANS, then write your values. don't skip steps bestie 😭
