What is the name of the common and oft-reimplemented game mechanics in which the level is a 2D grid consisting of obstancles, and the player can move from their current position in any direction (up, down, left, right) but will then move all the way until an obstancle stops him?

One example of this game mechanic is the Slippery Ice Tile in the Pokémon games.

    No, even the sliding puzzle tag doesn't fit. Unsure there's actually a term for this. Aug 28 '14 at 18:52

    I am unaware of any specific terminology given to this game play mechanic..

  • This reminds me of the old Warcraft III map Slide Ninja Slide.

You are looking for Frictionless Ice

Ice is not merely slippery; it's a physics-defying miracle lubricant that renders characters unable to make the slightest change in direction until the inevitable collision with an obstacle or wall, or in more malevolent circumstances, until the character is sent hurtling down a bottomless pit. So much as a single step of forward momentum is enough to send the character, puzzle block, or otherwise significant object sliding three screens in that direction. Of course, there is no diagonal.

This is actually developed from an old physics problem that goes with the study of Newton's law of motion (for each action there is an equal but opposite reaction).

The idea is that you would throw an object, which would cause you to receive the opposite and equal force to the throw, and move in a direction exactly opposite to my throw with just as much force as whatever was tossed.

  • I know of one game that has diagonal ice sliding, Runescape in the skill Dungeoneering there is a puzzle that has pressure pads on ice and you can slide diagonally across the ice. runescape.wikia.com/wiki/Ice_puzzle I haven't played another game that has this but thought it was interesting that the definition says no diagonal and Runescape seems to have broken this trend. :) Aug 28 '14 at 21:14

    I don't think we can really call TVTropes an authoritive source on gaming terminology.

    @Frank Why not? Is there a more authoritative source on media terminology you'd like to cite?

    More recently: Pokemon X/Y allowed diagonal sliding. I think one puzzle room was impossible until you figure out the game broke from tradition of cardinal directions only sliding. And then the rest of the sliding puzzles were too simple. Aug 29 '14 at 2:06
