Common Patterns

Handle NPC Gossip

local f = CreateFrame("Frame")
f:RegisterEvent("GOSSIP_SHOW")
f:SetScript("OnEvent", function()
    local options = C_GossipInfo.GetOptions()
    for i, option in ipairs(options) do
        print(i, option.name, option.gossipOptionID)
    end
    
    -- Auto-select if only one option
    if #options == 1 and options[1].selectOptionWhenOnlyOption then
        C_GossipInfo.SelectOption(options[1].gossipOptionID)
    end
end)

Display Player Choice

local f = CreateFrame("Frame")
f:RegisterEvent("PLAYER_CHOICE_UPDATE")
f:SetScript("OnEvent", function()
    local choiceInfo = C_PlayerChoice.GetCurrentPlayerChoiceInfo()
    if choiceInfo then
        print("Choice:", choiceInfo.questionText)
        for i = 1, C_PlayerChoice.GetNumPlayerChoices() do
            local option = C_PlayerChoice.GetPlayerChoiceOptionInfo(i)
            if option then
                print("  Option", i, ":", option.header, "-", option.description)
            end
        end
    end
end)

Get Tooltip Data Programmatically

-- Get item tooltip text without showing tooltip
local tooltipData = C_TooltipInfo.GetItemByID(12345)
if tooltipData then
    TooltipUtil.SurfaceArgs(tooltipData)
    for _, line in ipairs(tooltipData.lines) do
        TooltipUtil.SurfaceArgs(line)
        print(line.leftText)
    end
end

Check Chromie Time Status

local function ShowChromieTimeOptions()
    local options = C_ChromieTimeInfo.GetChromieTimeExpansionOptions()
    if options then
        for _, option in ipairs(options) do
            print(option.name, option.description, 
                  option.isCurrent and "(ACTIVE)" or "")
        end
    end
end

Register Slash Commands

SLASH_MYADDON1 = "/myaddon"
SLASH_MYADDON2 = "/ma"
SlashCmdList["MYADDON"] = function(msg)
    local cmd, args = msg:match("^(%S+)%s*(.*)")
    cmd = cmd and cmd:lower() or msg:lower()
    
    if cmd == "config" then
        -- Open config
    elseif cmd == "help" then
        print("/myaddon config - Open settings")
        print("/myaddon help - Show help")
    else
        print("Unknown command. Use /myaddon help")
    end
end

Key Events

Gotchas & Restrictions

1. •Gossip auto-select — selectOptionWhenOnlyOption flag means the game may auto-select; don't assume GOSSIP_SHOW always waits for input.
2. •PlayerInteractionManager types — Use Enum.PlayerInteractionType for type-safe checks; don't hardcode integers.
3. •Tooltip data API (12.0.0) — Use C_TooltipInfo for programmatic tooltip access rather than scraping GameTooltip text lines.
4. •Legacy API availability — Garrison, Covenant, and Azerite APIs still exist but content is no longer current. Some may be removed in future patches.
5. •Cinematic blocking — Some cinematics block all addon UI; plan for CINEMATIC_START / CINEMATIC_STOP.
6. •Player choices are timed — Some choices have countdowns. Check GetRemainingTime().
7. •SlashCmdList keys — Command names in SlashCmdList must be UPPERCASE. The slash aliases (SLASH_NAME1) are case-insensitive for matching.
8. •Chromie Time level cap — Chromie Time is only available to characters below the expansion's level range.
9. •Gossip POI — GetPoiForUiMapID() returns quest giver locations on the map, useful for minimap tracking.
10. •Report system — Reports require valid player locations; use C_ReportSystem.CanReportPlayer() first.
