Co do skakania to ja bym zrobił takie coś:
GML (draw)
var dir, len;
dir = point_direction( x,y, xprevious, yprevious );
len = point_distance( x,y, xprevious, yprevious );
motion_blur( len, dir );
draw_sprite_ext( sprite_index, image_index, x, y, image_xscale, image_yscale, image_angle, image_blend, image_alpha );
pobierz:
skrypt motion_blur
