stretch_sprite(3alleg4)

💖 stretch_sprite 💖

okay bestie, so this one is from the Allegro manual — it's a lil page about stretching sprites, and it lives in the Allegro game programming library. pull up a chair, we're gonna get into it 🫶

✨ NAME ✨

stretch_sprite — stretches a sprite to the destination bitmap. Allegro game programming library. 👑

🌸 SYNOPSIS 🌸

#include <allegro.h>

void stretch_sprite(BITMAP *bmp, BITMAP *sprite, int x, int y, int w,
int h);

🦋 DESCRIPTION 🦋

so it's literally draw_sprite() energy, except — plot twist — it can stretch the sprite image to whatever width and height you tell it. main character behavior fr fr 💅

but okay, there's some conditions, no cap:

• the sprite image and the destination bitmap have to be the same color depth. non-negotiable bestie 😭
• also the sprite image must be a memory bitmap. like, it has to be.

and here's a lil example, a tunnel-like effect situation:

/* Create tunnel like effect. */
for (step = 1; step
   int width = SCREEN_W / step;
   int height = SCREEN_H / step;
   stretch_sprite(screen, image, SCREEN_W / 2 - width / 2,
                  SCREEN_H / 2 - height / 2, width, height);
}

🫶 real talk: that's the example exactly as it appears, so don't come for me about the for loop — I'm just the messenger.
