draw_sprite_v_flip(3) Allegro manual draw_sprite_v_flip(3)NAME
draw_sprite_v_flip, draw_sprite_h_flip, draw_sprite_vh_flip - Draws the
sprite transformed to the destination bitmap. Allegro game programming
library.
SYNOPSIS
#include <allegro.h>
void draw_sprite_v_flip(BITMAP *bmp, BITMAP *sprite, int x, int y);
void draw_sprite_h_flip(BITMAP *bmp, BITMAP *sprite, int x, int y);
void draw_sprite_vh_flip(BITMAP *bmp, BITMAP *sprite, int x, int y);
DESCRIPTION
These are like draw_sprite(), but they additionally flip the image ver‐
tically, horizontally, or both, respectively. Flipping vertically means
that the y-axis is reversed, while flipping horizontally means that the
x-axis is reversed, between the source and the destination. This pro‐
duces exact mirror images, which is not the same as rotating the sprite
(and it is a lot faster than the rotation routine). The sprite must be
a memory bitmap. Example:
if (key[KEY_RIGHT])
draw_sprite(screen, hero_right, pos_x, pos_y);
else if (key[KEY_LEFT])
draw_sprite_h_flip(screen, hero_right, pos_x, pos_y);
else
draw_sprite(screen, hero_idle, pos_x, pos_y);
