rotate_sprite_v_flip(3alleg4)

πŸ’– NAME πŸ’–

rotate_sprite_v_flip β€” bestie, this one rotates a sprite and flips it. It lives in the Allegro game programming library, and it's lowkey iconic. πŸ¦‹


✨ SYNOPSIS ✨

#include <allegro.h>

void rotate_sprite_v_flip(BITMAP *bmp, BITMAP *sprite, int x, int y,
fixed angle);

Yes, that's the whole signature, she's not complicated, she just works. πŸ’…


🌸 DESCRIPTION 🌸

Okay so picture rotate_sprite, right? Same energy, same vibe β€” but this one flips the image vertically FIRST, and then rotates it. The order is not a suggestion, bestie, that's literally the whole point of this function. πŸ™ˆ

Now for the galaxy-brain part. ✨ Want to flip horizontally instead? Use this exact routine, but add itofix(128) to the angle. That's it. That's the trick. The way that a 128-unit angle offset just becomes a horizontal flip? Ate. πŸ’…

And if you want to flip in both directions at once? Then you call rotate_sprite() β€” the regular one, no _v_flip β€” and add itofix(128) to its angle. Two flips, one function, periodt. πŸ‘‘

Quick vibe check so you don't mix them up: vertical flip = this function. Horizontal flip = this function + itofix(128). Both = rotate_sprite() + itofix(128).
