In some circumstances, it may be benefecial to use spell textures, rather than names, to identify buff and debuff effects - textures require no additional localization, while buff names will require to be localized for every language your addon should support. This HOWTO describes an easy mechanism to find out if a certain unit is affected by a specific buff or debuff. | In some circumstances, it may be benefecial to use spell textures, rather than names, to identify buff and debuff effects - textures require no additional localization, while buff names will require to be localized for every language your addon should support.

While we could write separate functions for buffs and debuffs, it's easier to write a single ''iterator'' function and pass the desired spell effect type as an argument - effectively cutting down the amount of code required for the whole routine. We can get the buff's texture from [[API UnitBuff|UnitBuff]] and debuffs from [[API UnitDebuff|UnitDebuff]]: | While we could write separate functions for buffs and debuffs, it's easier to write a single ''iterator'' function and pass the desired spell effect type as an argument - effectively cutting down the amount of code required for the whole routine.
