simple addon to display Holy Power Party

[Prega]

i ve written some code to display Holy power for my other paladins in my main screen.

wasted some hours trying to manage Holy power from others with combat log parsing.
this approach doesn t requires communication between clients, but it s incredibly complicated.

Following Jamba example, with communication between clients, this task is really simple.
I m not an expert about addon scripting, Lua and wow api.

how it works? simple mode. atm there are not configuration options.



- there are 2 .lua files: 1) file_1 for main; 2)file_2 for slaves
- atm many things are not implemented. Addon shows values for Holy power using simply a numer (0-3 range).
- no texture use atm.
- font type and dimension is defined in "text1:SetFont("Fonts\\ARIALN.TTF", 32)" line: it s customizable path and dimension.
-
- Lua files are different for Main and slaves. if you want test it with a main char ='other then paladin', you need to change code a bit.
nothing complicated but frame1 and event UNIT_POWER and handler1 function are not needed and can generate errors if left.
- MyGrp table is my grp composition.

now the code.
Lua code file_1:

-- player [1] is always leader. others are 2-5
-- Holy Power values are shown with text

local MyGrp = {
[1] = "Prega",
[2] = "Alad",
[3] = "Redcrox" ,
[4] = "Whitecrox" ,
[5] = "Yargo"
}
---------------------------------------
---------------------------------------
local gn = #MyGrp
local myname =UnitName ("player")
local w = "WHISPER"

--------handle event UNIT POWER for main:not useful if main is not a paladin
function handler1(self,event, ...)

    local source, type = select(1, ...);
    if source == "player" and type == "HOLY_POWER" then
        p = UnitPower("player",9)
        text1:SetText(p)

    end
end

-----handle event CHAT_MSG_ADDON: sources are other members of team, values of HP for all are displayed on main screen only atm.
function handler2 (self, event, ...)
    local prefix, msg, distr, sender = ...;
    if prefix == "Multihp" and  msg and sender == MyGrp[2] then
    msgn = tonumber(msg)

This is neat, and could be adapted for whatever... combo points, holy power, etc.

[remanz]

Awesome~, Thanks for sharing.

[Sbrowne55]

As far as I know, the API for UnitPower has types, and combo points aren't listed as usable.

Did you add this code into a folder, or stuffed it inside another addon?

[Prega]

As far as I know, the API for UnitPower has types, and combo points aren't listed as usable.

yes exact.
combo points are not "shown" with UnitPower("unit",type").
In UnitPower "unit" is the "unit"-power to show.
and "type" has values from 1 to 9:
1)mana,2)rage,3).....9)holypower, no combo points but energy is avaible for rogues/cat druids here with this API function.
for many types of energy it works for "player" as "unit" but doesnt work for specific characters names( bad limit for Mboxers), so i decided to use communications.
In this way it works outside groups, communications are always sent and recieved if characters involved in send-recieve are online in same server at same time. Ofc characters need to be configured in the code as senders and reciever.

not sure what happens with chars names in BG, but according some documents i read, simple chars names like "Prega", for example, in BG become "Prega-Alonsus", where alonsus is my server name.
a simple condition added in 'IF then' statement will solve all communications issues in BG.

Combo Points are different. the main issue is combo points are target related.
Manage combo points surely is a bit + complicated.
somenthing have to happen when you change target or if you targetting for mistake/lag something wrong: otherwize you display wrong values.
But there are some events "generators" like UNIT_COMBO_POINTS, fired when combo points happen and usable in a similar logical scheme to communicate and display the values.
Or simply use function GetComboPoints(unit, target): unit="player" and target is target explicitly declared. looks easier to use but it needs some code to manage what happens when targets are different for slaves and main.
This happens expecially when main switch target etc.

A lot easier looks display Rune values for DK.
Rune works with UnitPower, it is type 5.
Not sure about what format have data output (not tested atm).
maybe requires some little fix.
Explain. You know Runes are 3 "sub-types": blood, frost and unholy.
it s good know amount avaible and, ofc, sub-type in real time, not just a simple undefined number.

Did you add this code into a folder, or stuffed it inside another addon?

this is a little addon internal code:
i know it s not a complete addon...in normal sense hehe.
but little time to create a easier way to use it.
idea was to share general infos about how it s possible and "easy" manage things like holy power etc etc with simple code (believe me it s a simple code, rewritten trying to avoid usage of strange complex functions, avoiding xml usage, avoiding framework usage etc etc, keeping in this way code + readable)
yes, , atm customization cant result so easy .
here missing .toc file, a needed file for any addons: it defines .lua file association and, implicitly, addon folder.

i try to show a step by step a customization process.

open a notepad file, copy the whole named file_1 content in your empty notepad file. as above.
Save this file as a .Lua, giving it as name "Multihp.lua". Tips: verify it is saved as a .lua not a.txt.

In file_1:
-STEP1

-- player [1] is always leader. others are 2-5
-- Holy Power values are shown with text

local MyGrp = {
[1] = "Prega",
[2] = "Alad",
[3] = "Redcrox" ,
[4] = "Whitecrox" ,
[5] = "Yargo"
}

sub "Prega" with your main name, aka name of char where you want show holypower for all group.keep "name" format.
after that, keeping number order, sub "Alad" name with your char nr 2 and then redcrox and so on etc etc.
------------------
-STEP2

--------------------------frame1=PREGA--local frame for main(prega) hp--
frame1 = CreateFrame("Frame", "frame1", UIParent)
text1 = frame1:CreateFontString()

frame1:SetPoint("CENTER",0, -100)
frame1:SetWidth(128)
frame1:SetHeight(128)
frame1:SetMovable(true)
frame1:EnableMouse(true)
text1:SetAllPoints(frame1)
text1:SetFont("Fonts\\ARIALN.TTF", 32)


frame1:RegisterForDrag("LeftButton")
frame1:SetScript("OnDragStart", function(self) self:StartMoving() end)
frame1:SetScript("OnDragStop", function(self) self:StopMovingOrSizing() end)

--------------------------frame2=ALAD
frame2 = CreateFrame("Frame", "frame2", UIParent)
text2 = frame2:CreateFontString()......................... .

Delete the bold-underline text if you going to use a Main char is NOT A PALADIN.
-----------------

STEP3

--------handle event UNIT POWER for main:not useful if main is not a paladin
function handler1(self,event, ...)

    local source, type = select(1, ...);
    if source == "player" and type == "HOLY_POWER" then
        p = UnitPower("player",9)
        text1:SetText(p)

    end
end

Again, IF YOUR MAIN IS NOT A PALADIN, delete. bold-underline text
--------

STEP4

-------- set handlers and register events for each frames

frame1:SetScript("OnEvent", handler1)
frame2:SetScript("OnEvent", handler2)
frame3:SetScript("OnEvent", handler2)
frame4:SetScript("OnEvent", handler2)
frame5:SetScript("OnEvent", handler2)
frame1:RegisterEvent("UNIT_POWER")
frame2:RegisterEvent("CHAT_MSG_ADDON")
frame3:RegisterEvent("CHAT_MSG_ADDON")
frame4:RegisterEvent("CHAT_MSG_ADDON")
frame5:RegisterEvent("CHAT_MSG_ADDON")

Delete, IF YOUR MAIN IS NOT A PALADIN, bold-underline text

Save and exit
-------------------------

STEP ON file_2.lua
Open a new notepad empty file, copy in it code from file_2 above and give it name "Multihp1.lua" and save as .lua file type.

in file_2 content, at 1st line

---------------------------------------
local gl = "Prega"
local myname =UnitName ("player")
local w = "WHISPER"

change "Prega", with name of your Main name.
save and exit.

go in wow/interface/addon folder and create a new folder called "Multihp" for your main char addon.
Put Multihp.lua in this folder.

in this folder create a new notepad empty file, name it "Multihp.toc"
copy/paste this content:

## Author: Me
## Interface: 40000
## Title: Multihp
## Version: 1.0
Multihp.lua

save as .toc file and exit

for each slaves, if you use multiple wow folders, or just 1 time if you use a single wow folder, create a new folder in wow/interface/addons path and name it "Multihp1". It hosts the addon for slaves.
in this folder create the .toc with notepad, as explained and name it "Multihp1.toc"

## Author: Me
## Interface: 40000
## Title: Multihp1
## Version: 1.0
Multihp1.lua

unique things different are the bold-underline text.
put in folder Multihp1 the file Multihp1.lua file.

at the end each folder, Multihp and Multihp1, have to contain 2 files:
in Multihp folder, files are Multihp.lua and Multihp.toc. Multihp.lua is file_1 modified
in Multihp1 folder, files are Multihp1.lua and Multihp1.toc. Multihp1.lua is file_2 modified.

check for main char only Multihp is active as addon and Multihp1 is active as addon only for slaves chars.

i know, it sounds complicated

for many types of energy it works for "player" as "unit" but doesnt work for specific characters names( bad limit for Mboxers), so i decided to use communications.

I just want to make sure I understand this clearly because I would like to go back to my DK and 4 paladin team...

Is this communication solution required because UnitPower("party2", 9) always returns zero, even if the character in slot party2 is a paladin?

Alternatively, does UnitPower(unit, 9) only return meaningful values when unit == "player"? Is this a bug or a feature of the API?

Thanks,

Alge

I don't think this communication solution required it is optional.

i did several tests.

Do an example.
do a macro with this script inside. It assigns s=UnitPower and print s in the chat.

generic script, without real parameters for UnitPower:
/run s = UnitPower(unit,powertype); print s;

as said, this script could be tested in a macro button, if you click this macro it prints in chat current value registered by UnitPower function.

real example: i test mana, powertype 0.
for my paladin, Yargo. im doing this on other char, for example on my druid Chymera.

/run s = UnitPower("Yargo",0); print s;
result: script shows current mana for yargo.5591

example: i test mana for "party1". im groupped with yargo ofc.
/run s = UnitPower("party1",0); print s;
result: script shows current mana for party1.5591
etc etc.

now Holy Power type.
test for powertype = 9, aka Holy Power

same tests, for yargo and for party1
/run s = UnitPower("party1",9); print s;
result is always 0. same for "Yargo".

i think it s not something wrong, but it s working as inteded, exactly as happens for combo points, or Rune.
Blizzard probably thinks HolyPower is a useful value just for current player.

Thanks for the response Prega - very clear explanation.
