--- LibRangeCheck-2.0 provides an easy way to check for ranges and get suitable range checking functions for specific ranges.\\
|
||
|
|
-- The checkers use spell and item range checks, or interact based checks for special units where those two cannot be used.\\
|
||
|
|
-- The lib handles the refreshing of checker lists in case talents / spells / glyphs change and in some special cases when equipment changes (for example some of the mage pvp gloves change the range of the Fire Blast spell), and also handles the caching of items used for item-based range checks.\\
|
||
|
|
-- A callback is provided for those interested in checker changes.
