The '''Multiple Tank Glitch''' | The '''Multiple Tank Glitch''' is a [[glitch]] in [[Microsoft's version of Chip's Challenge]] caused by adding a [[tank]] to the [[Monster order|monster list]] multiple times. It does not exist in other [[ruleset]]s, and it is one of only a handful of glitches that is not emulated by [[Tile World]]. | ||
For other | For other [[monster]]s that are added to the monster list multiple times, the square simply spawns more the number of monsters equal to the number of instances in the monster list. This is not true of tanks, which only spawn once no matter how many times it is added to the monster list - except in a few special circumstances. These special cases can achieve very bizarre effects in a level designed with this glitch. | ||

Notice how the first force floor appears to have slid two spaces to the right. Suppose instead that the tile under the tank was a west force floor instead of an east force floor.

Recall that there are four copies of each monster in the tile set, one for each direction. This is important to distinguish the direction in which a monster such as a [[glider]] is moving. In order to determine which index tile to choose, Chip's Challenge groups all the monster tiles into sets of 4 consecutive tiles. Within each group, the order of tiles in the set is north, west, south, east. In addition, the first tile in each group has an index that is a multiple of 4. | Recall that there are four copies of each monster in the tile set, one for each direction.

In this glitch, tiles that are not normally monsters are also grouped as such since they behave as monsters for one turn. In the first example, the tiles [[Clone block|Clone block S]], [[Clone block|Clone block E]], [[Force floor|Force floor N]], [[Force floor|Force floor E]] are grouped together as one monster unit | In this glitch, tiles that are not normally monsters are also grouped as such since they behave as monsters for one turn. In the first example, the tiles [[Clone block|Clone block S]], [[Clone block|Clone block E]], [[Force floor|Force floor N]], [[Force floor|Force floor E]] are grouped together as one monster unit - although in reality, this grouping does not make any sense since these are not monsters. Note that Force floor E is designated as the "east" tile in this group, since it is the last tile in the group. This is why the east force floor happens to remain unchanged while it slides east. | ||
In the second example, the west force floor is the first tile in the group [[Force floor|Force floor W]], [[Exit]], [[Blue lock]], [[Red lock]]. As | In the second example, the west force floor is the first tile in the group [[Force floor|Force floor W]], [[Exit]], [[Blue lock]], [[Red lock]]. As the red lock is the tile that is designated "east" in this group, this is what the west force floor turns into as it slides east. By extension, one can expect that if the second example were flipped so that the west force floor now slides west, it will turn into an exit (which is the "west" tile of its group), and this is indeed what happens. | ||

This diagram shows many possible tiles that can be created using the glitch. Each group of 4 tiles is outlined in a unique color, where the topmost tile in the section would be the "north" tile, followed by "west", "south", and "east".

Each group of 4 tiles is outlined in a unique color, where the topmost tile in the section would be the "north" tile, followed by "west", "south", and "east". Using this diagram, one can predict that if the tank starts on a SW [[ice]] corner and moves south, the ice corner will turn into a fake [[blue wall]]. If it instead moved east, it would become a ''real'' blue wall, and if it moved north, the ice corner would remain the same tile. | ||
There are also other tiles that can be created which cannot be achieved through simply morphing a tile one time. If a real blue wall created using the glitch is bumped into while it is sliding, it will morph into a water tile, as this is the designated "east" tile of the group the regular wall is in - [[Floor]], [[Wall]], [[Computer chip]], [[Water]]. If a [[block]] is pushed into the water tile as it is sliding, it will become [[dirt]] and can then morph into a south or east [[thin wall]]. It can also morph into another block if it slides to the south, though once it does the tile will not be able to morph again. | |||
