rotate_sprite_lit(3) Allegro manual rotate_sprite_lit(3)
NAME
rotate_sprite_lit - Rotates a sprite. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void rotate_sprite_lit(BITMAP *bmp, BITMAP *sprite,
int x, int y, fixed angle);
DESCRIPTION
Draws the sprite image onto the bitmap. It is placed with its top left
corner at the specified position, then rotated by the specified angle
around its centre. The angle is a fixed point 16.16 number in the same
format used by the fixed point trig routines, with 256 equal to a full
circle, 64 a right angle, etc. All rotation functions can draw between
any two bitmaps, even screen bitmaps or bitmaps of different color
depth.
Positive increments of the angle will make the sprite rotate clockwise
on the screen, as demonstrated by the Allegro example.
