Я собираюсь создать новую тайловую основу движка игры, которая (по
моему мнению) поможет создавать множество разнообразных игр, путем
изменения лишь некоторых параметров.Земля : обычная земля, с нормальным ускорением и силой трения.Лед : скользкое покрытие со сниженной силой трения и ускорением.ACTIONSCRIPT: tile_size = 20 ;
