LibPlayerSpellInfo-1.0
A library to provide extended information regarding player spell action/macro cast requirements (such as reagent, equipment and form requirements).
Includes:
- Spell requirement API's that determine if a spell meets equipment, form, and/or reagent requirements.
- There are also API's for parsing entire macrotext objects and determining if a spell name/link/id is a valid player spell/companion/mount.
- Cast requirement API's (basically beefier IsUsableSpell/Action/Item functions) that determine nearly all1 casting requirements for any given spell/item/action.
1 Excluded parameters are whether the player has control of their character (which can be determined with LibUnitControl-1.0) and whether the player's target is within LOS, which is currently impossible to discern.
Usage
Here's a relatively simple display hook for use with the default blizzard actionbars that improves color indication of a whether a spell can be cast:
local lps = LibStub("LibPlayerSpellInfo-1.0") local hook_ActionButton_OnUpdate = ActionButton_OnUpdate function ActionButton_OnUpdate(button, elapsed) if button.rangeTimer and ( button.rangeTimer - elapsed <= 0 ) then ActionButton_UpdateUsable(button) end hook_ActionButton_OnUpdate(button, elapsed) end function ActionButton_UpdateUsable(button) local name = button:GetName() local icon, texture = _G[name.."Icon"], _G[name.."NormalTexture"] local isKnown, hasReact, _, inRange, hasUnit, _, hasMana hasEquip, hasReagent, inForm = lps:ActionUseInfo(button.action) if ( not inForm ) then -- Green overlay icon:SetVertexColor(0, 0.4, 0.2) texture:SetVertexColor(0, 0.4, 0.2) elseif ( not hasEquip ) or ( not hasReagent ) then -- Orange overlay icon:SetVertexColor(0.4, 0.2, 0) texture:SetVertexColor(0.4, 0.2, 0) elseif ( not hasMana ) then -- Blue overlay icon:SetVertexColor(0.2, 0.3, 0.7) texture:SetVertexColor(0.2, 0.3, 0.7) elseif ( hasUnit and not inRange ) then -- Red overlay icon:SetVertexColor(0.7, 0.15, 0.15) texture:SetVertexColor(0.7, 0.15, 0.15) elseif ( isKnown and not hasReact ) then -- Gray overlay icon:SetVertexColor(0.4, 0.4, 0.4); texture:SetVertexColor(1.0, 1.0, 1.0) else -- No overlay icon:SetVertexColor(1.0, 1.0, 1.0) texture:SetVertexColor(1.0, 1.0, 1.0) end end
