sp_move_x

Prototypevoid sp_move_x(int active_sprite, int pixels)

sp_move_x() sets the number of pixels the sprite is moving horizontally per sp_timing() interval. This is used to make sprites move in directions other than the 8 used with sp_dir(), or to finely tune movement speed.

If pixels is negative, the active_sprite will move left. If pixels is positive, the active_sprite will move right.

    sp_move_y(&junk, -2);
