Editing Spring mining

'''Spring mining''' (official name pending) is a glitch in [[Chip's Challenge 2]]. It allows entities capable of pushing blocks to push a [[block]] off of a tile that becomes solid when moved off of (at least briefly) while also following it. In short, it lets you follow blocks [[flick]]ed off tiles under certain circumstances. It was first analyzed (and initially coined) by ncrecc.

Specifically, this works with a legally pushable block on a [[recessed wall]], a [[railroad]] junction where the next position is normally illegal to move onto, a [[swivel door]], or a [[turtle]].

It is named after the level [[Spring Mines]], where this can commonly be observed by pushing any of the blocks on recessed walls upwards as a [[walker]] moves away from it.

No relation to [[spring step]]ping or [[Spring slide|spring sliding]].

== Sliding method ==
Spring mining may be achieved by sliding onto the minable tile in any manner, including slow-sliding via exiting a [[teleport]]. Spring mining in this manner can be prevented if you override in the direction of the tile directly before reaching it.

== Retreating monster method ==
This is the more obscure method. Spring mining may also be achieved by holding a blocked push on the minable tile against an entity that moves to another tile.

For [[Chip]] and [[Melinda]] (and only they), this only works if the moving entity in question started after them in [[reading order]]. Chips and Melindas introduced to the level via waterbirth will always be able to spring mine this way, regardless of their starting point. Chips and Melindas introduced via a [[clone machine]] will use the clone machine as their starting point.

== Special cases ==
[[Yellow tank]]s cannot spring mine onto recessed walls, as they cannot enter recessed walls to begin with.

All entities that can push blocks and are not Chip or Melinda will spring mine blocks on turtles by default, and do not need either of the above setups for turtle spring mining.

[[Player mimic]]s will always spring mine blocks instead of flicking them.

[[Rover]]s and yellow tanks cannot spring mine via the retreating monster method.

Blocks of any type will instantly disappear if they spring mine another block off of a recessed wall or swivel door.

Trying to use the retreating monster method on a railroad corner with any type of [[directional block]] other than 4-way will result in the block becoming stuck in place and immovable unless pushed off by an entity with a [[railroad sign]].
