Module:Tier List

From Dragdown
Tier List Generator written by Tarkus Lee from Dustloop

Module:Tier_List is used to generate tier lists directly within the wiki using HTML, and the existing character labels.

Usage

A tier list requires that arguments be present in order.

  1. All of the tiers, ordered from top to bottom

Within a given tier, you must define the label for that tier (the letter that appears inside of the colored square) followed by a semicolon character (';').

Short Names in Labels

The tier list will attempt to find the appropriate icon and link for a given character. If you choose not to use the full name of a character, you must set up a necessary redirect from the short name to the full name. This applies to both the icon file and the character page itself.
