This space optimization is even more efficient when some big sprites have concave shape (i.e. Metal Slug is the very first title in SNKвЂ™s legendary 2D run & gun action shooting game series where it all began. The bounding box of a sprite may intersect the bounding box of another sprite, but the shape of this sprite is always separated from the shape of any other sprites with at least 1 transparent pixel. Sprites are placed close to each others, depending on their shape. The developers are aware of the wasted memory and started to optimize the space in the sprite sheets. The disadvantage is that this method of placement wastes a lot of memory because of all the additional transparency of each sprite, especially when sprites have different width and height. Sprites could be evenly placed in the sprite sheet according to their bounding box. !(metal_slug_sprite_detection_coloring.png) The masks of these sprites are respectively: !(metal_slug_sprite_standing_stance_large.png) For example, the sprite sheet (metal_slug_sprite_standing_stance_large.png) contains the 3 following sprites: The mask of a sprite defines the 2D shape of the sprite. Marco perler sprite from the Metal Slug series by Hirosspriteshop, 7.50. !(metal_slug_sprite_detection_bounding_boxes.png) This bounding box is defined with two 2D points top_left and the bottom_right, which their respective coordinates x and y are relative to the top-left corner of the sprite sheetвЂ™s image. There is also this coo forklift truck style Slug that is a lot of fun to use and it. The crawler is more of a defensive kind of Slug and probably my least favorite of the bunch. Metal Claw is really cool as it just shreds the heck out of any enemies that you come across. !(metal_slug_sprite_sheet_large.png)ДЄ frame ( bounding box) can be used to delimit the sprite in the sprite sheet. Bradly which was actually an enemy vehicle in Metal Slug 2 can now be used. Using sprite sheet, video game developers create sprite sheet animation representing one or several animation sequences while only loading a single file: In other words, sprite sheets pack multiple sprites into a single picture.

To help manage sprites and avoid using so many images, many games use ( ) (also known as image sprites).ДЄ sprite sheet consists of multiple sprites in one image. Loading each of these as an individual image would consume a lot of memory and processing power. It is not uncommon for games to have tens to hundreds of sprites. !(metal_slug_sprites_running_with_gun.png) Several sprites, representing a same object, can be rendered in quick succession to give the illusion of movement of this object ( animation).ДЇor example, the animation of the hero Marco Rossi (Metal Slug), running with a gun, is composed of 9 sprites: !(2d_video_game_cannon_fodder.jpg) | !(2d_video_game_commando.jpg) | !(2d_video_game_metal_slug.png) |
