Mouse Panel Glitch: Difference between revisions

The '''Mouse Panel Glitch''' is a [[glitch]] in the [[MS ruleset]] of [[Chip's Challenge]]. It was first reported on November 29, 2002 by [[Anders Kaseorg]]. It has been used for speedrunning in three [[CCLP2]] levels to date, with the first being [[Captured]], where Kaseorg added 3 extra seconds. On the same day as that report, [[David Stolp]] also found it to be useful in [[Debug File]]. Since then, [[Madness II]] and [[Switch Hit]] have each had an extra second added to them, and it is possible to add .2 seconds to [[After the Rainstorm]] by using a slight variation. The Mouse Panel Glitch is not responsible for any additional seconds in CC1.

The glitch applies when Chip is next to any block with any Chip-[[acting wall]] in the direction facing him: a [[thin wall]] must block Chip from moving onto the square, not the block from moving off. To use it, click the mouse on any square ''not'' on the same row or column which would result in Chip's next move being an attempt to enter the block's square. Assuming that the [[flick]] is a legal move, the flick will occur ''and'' Chip will move in the legal direction towards the clicked square, within one turn rather than two. If the flick is ''not'' a legal move, then a [[ram]] has been executed similarly.

If there are flickable or rammable blocks in ''both'' directions of the mouse click, then both blocks will get the treatment at the same time, using only one move rather than the two it would normally take. See [[User:Geochip1|Tyler Sontag]]'s level 316, ''So Totally Extremely Unfair'', for an example of how this variation works.

The second variation is referenced above, which allows the player to execute a ram using the glitch. Since this does not move the block, this variation is only useful when it is sliding on [[force floor]]s or [[ice]] and it cannot move because the space in front of it is a block-acting wall. As just removing the obstacle will cause Chip to be flattened, Chip has to ram the block in order to remove the obstacle safely.

The [[computer chip]] section of Debug File is shown above. The thin walls face R, L, R, L, R and L in forwards [[reading order]]. To get the blocks onto the [[water]] with the computer chips underneath, Chip must flick each block. If Chip clicks *D-L from [4, 2], although he has [[flippers]], this would cause the chip to be erased. Chip must click specifically *U-L, such that this is the result on the following turn:

When using the mouse in any form, it will continue to carry Chip to the square clicked on until Chip runs into a wall. To avoid this, hit the keys ''firmly'' such that Chip's Challenge cannot read the mouse click beyond the time of its use. <!---Does this happen in Tile World? I never had trouble with this when I played Captured in Tile World, but it was very, very annoying in MS.--->

An easy way to use the Mouse Panel Glitch in either MS or [[Tile World]] is to pull up a second game window in advance, pause the game when the glitch is ready to be used, and find a square Chip can click on by using the other window as a guide. Chip always stays in the center of the 9x9 visible [[grid]] unless that visible grid runs into the edge of the level, and a square 2R D from Chip in one window will remain 2R D from Chip as long as Chip stays at least four squares away from the border. After marking this square with his finger, the player can switch windows, move the cursor under the held finger, and the cursor will stand on the correct space.
