== [[Acting wall]] redirecting ==
== [[MS Ruleset|MS]] behavior ==
There are few strategies for redirecting blobs normally, but sometimes they can be nudged, encouraged, and even forced into a specific path by acting walls, or additionally by existing [[acting dirt]]. This can be desirable or undesirable depending on the situation. Usually, if Chip is trying to avoid being hit by blobs in a ''specific'' section of route - such as running to the [[thief]] in [[Abandoned Mines]] - the fewest acting walls are preferred to give the blobs less chance of blocking other blobs' desired directions, such that those blobs would be more likely to hit Chip.
In MS blobs move every other turn, depending on the level's current [[Odd and even step|step]]. A blob's direction is randomly chosen from all ''legal'' directions, meaning that if a path is open a blob will always move.


If there is no set route through the room, acting dirt exists in the pathway, or the blobs are instead intended to remove [[bomb]]s or hit [[button]]s that Chip cannot reach, then blob-acting walls will often help. In the first case, they force the blobs into a more important decision as to which path they are guarding. Acting dirt will also define a safe route through that the blobs cannot infringe on, which is made more secure by the acting walls. The third case is intended to encourage blobs to move closer to the target by reducing its options. If other blobs take away the option of retreating, the initial blob is more likely to move closer to where Chip wants it.
A side effect of the random movement is that a blob on a cloner will clone in any legal direction, regardless of the direction of the blob on the [[clone machine]].


The ultimate situation in blob redirection is the following:

In Lynx blobs move at half the speed of other monsters, taking 8 ticks to complete a move. Unlike MS blobs will randomly choose ''any'' direction, meaning that even with an open path blobs can remain stuck for some time.

Blobs on clone machines and moving through traps do follow the direction of the blob, cloning or moving according to the direction of the blob on the machine or in the trap.


In this case, the blob has only two choices: D back onto a north [[force floor]] with no effect, or U, which will send it >U to boot. The same choices then apply, and the second U move leads to death on the [[bomb]], which frees the [[exit]].

In Steam blobs act almost identical to Lynx except for the random selection. In Steam levels have 3 settings for blobs: '''Deterministic''', which causes all blobs to act the same between deaths; '''4 Patterns''', which causes the blobs to cycle through 4 possible patterns of movement; and '''Extra Random''', which causes the blobs to cycle through 256 possible patterns move movement.

The blob is an amoeba-like green monster whose direction is completely random, and moves at half the rate of other monsters. The only limits on a blob's direction are illegal moves.

In Chip's Challenge 1, the blob is the only monster that is never cloned.

General mechanics[edit]

The direction of the blob usually means nothing, because the randomly selected direction will take effect from a blob's first move onwards. This random value is not reset between deaths and levels so blobs will usually move differently between attempts[1].

MS behavior[edit]

In MS blobs move every other turn, depending on the level's current step. A blob's direction is randomly chosen from all legal directions, meaning that if a path is open a blob will always move.

A side effect of the random movement is that a blob on a cloner will clone in any legal direction, regardless of the direction of the blob on the clone machine.

Lynx behavior[edit]

In Lynx blobs move at half the speed of other monsters, taking 8 ticks to complete a move. Unlike MS blobs will randomly choose any direction, meaning that even with an open path blobs can remain stuck for some time.

Blobs on clone machines and moving through traps do follow the direction of the blob, cloning or moving according to the direction of the blob on the machine or in the trap.

Steam behavior[edit]

In Steam blobs act almost identical to Lynx except for the random selection. In Steam levels have 3 settings for blobs: Deterministic, which causes all blobs to act the same between deaths; 4 Patterns, which causes the blobs to cycle through 4 possible patterns of movement; and Extra Random, which causes the blobs to cycle through 256 possible patterns move movement.

Origins[edit]

Melinda's special dispatches reveal where the blob came from: it was an accidental creation from a series of failed genetic experiments. Blobnet was the first appearance of the blob, and they largely appeared sparsely from then on, save for Blobdance much later in the game.
