410 Part III ■ Advanced Addon TechniquesPLAYER_REGEN_ENABLEDThe PLAYER_REGEN_ENABLED event will fire when the player leaves combat, andas a result the logic in this section is much the reverse of entering combat.You turn the combat flag off, and update the total amount of combat time bysubtracting the current time from the start time. Next you clear the OnUpdatefunction and update the frame, which will show the total stats instead of therolling average.Creating the Frame DisplayAs an initial example, the display for this addon will be series of text stringsthat contain the damage and healing information. Eventually, you’ll want toexpand it to use status bars instead of text strings. Create your CreateFrames()function:function CombatStatus:CreateFrames()self:ClearAllPoints()self:SetPoint(“TOP“, MinimapCluster, “BOTTOM“, 0, -15)self:SetWidth(300)self:SetHeight(150)self.rows = {}for i = 1, 10 dolocal row = self:CreateFontString(nil, “OVERLAY“, i“GameFontHighlight“)row:SetText(“Blah“)self.rows[i] = rowif i == 1 thenrow:SetPoint(“TOPLEFT“, 0 ,0)elserow:SetPoint(“TOPLEFT“, self.rows[i-1], “BOTTOMLEFT“, 0, 0)endendendThe frame is anchored directly below the minimap cluster and consists of 10different font strings.Updating the Frame DisplayThe actual calculations are accomplished in the UpdateFrame() method. Addthis method to your file anywhere below the TakeSnapshot() method, becauseit uses the units table defined just before that function.function CombatStatus:UpdateFrame(elapsed)for idx, unit in ipairs(units) dolocal row = self.rows[idx]
