[WotLK][TC][Eluna][AIO] Custom class powerType / resource
« on: July 25, 2016, 07:13:03 pm »
Couldn't find much info on this so I tried to add custom power types that go in the mana bar slot (like mana, energy, rage, runic power, focus). This is for TrinityCore 3.3.5 with Eluna and AIO. It's entirely possible that I forgot about a crucial core modification, so please let me know if there are any problems. I'm also not a very good programmer, so feel free to post improvements.

[media:3bjzc74y]https://www.youtube.com/watch?v=AgKHu6Z8yig[/media:3bjzc74y]

Full instructions are provided at the top of the code. Sorry for line wrap issues. It's slightly less painful on pastebin (or if you copy+paste it into an editor).

Script:
http://pastebin.com/asPaW32y

Alternative copy:
Code: [Select]
--[[INSTRUCTIONS:
1 Requires core modification to fix stance/form changing:
in Unit.cpp
void Unit::setPowerType(Powers new_powertype)
change:
case POWER_HAPPINESS:
SetMaxPower(POWER_HAPPINESS, uint32(std::ceil(GetCreatePowers(POWER_HAPPINESS) * powerMultiplier)));
SetPower(POWER_HAPPINESS, uint32(std::ceil(GetCreatePowers(POWER_HAPPINESS) * powerMultiplier)));
break;
  to:
case POWER_HAPPINESS:
if (GetTypeId() == TYPEID_PLAYER && GetMaxPower(POWER_HAPPINESS) >= 0)
break;
SetMaxPower(POWER_HAPPINESS, uint32(std::ceil(GetCreatePowers(POWER_HAPPINESS) * powerMultiplier)));
SetPower(POWER_HAPPINESS, uint32(std::ceil(GetCreatePowers(POWER_HAPPINESS) * powerMultiplier)));
break;

You may want to apply other core modifications to give POWER_HAPPINESS as neutral of a behavior as possible and script
functionality specific to each custom powerType when a specific player event occurs, or add some class checks in the
core when a player's POWER_HAPPINESS is manipulated.

2 If you want a class to use a custom resource, set the SERVER SIDE powertype for that class to 4 (HAPPINESS)
in ChrClasses.dbc (the field that has a default value of 6 for Death Knights). Client side changes to ChrClasses.dbc
are not required. Happiness is simply the powertype we use behind the scenes for all custom powertypes.

3 Next, add an entry for your custom powertype in the customPowerTypes table. Each entry should have a table of classes,
an id, a powerString, a bar color table, a defaultMax value and a consumingSpells table (for correct GetSpellInfo powerType).
defaultMax should be the value you want, multiplied by 1000. All Happiness values have to be multiplied by 1000.

4 To create ANY spell (in Spell.dbc) that uses or generates your custom powertype, give it a power cost or energize effect
for powerType 4 (HAPPINESS). Make sure Happiness values (costs, energize effects etc) are multiplied by 1000.


TROUBLESHOOTING:
Make sure that the class has the powerType set to 4 (HAPPINESS) in SERVER SIDE ChrClasses.dbc.
Make sure that the class is listed in only one customPowerTypes[POWERTOKEN].classes table.
Make sure table entries are separated by commas.
MAKE SURE ALL RESOURCE VALUES ARE MULTIPLIED BY 1000. Happiness for some reason needs everything
multiplied by 1000. That includes spell costs and generation or if you're setting current power value
or maxvalue. All of them need to be multiplied by 1000.
Custom spells should always use 4 (HAPPINESS) in Spell.dbc, but everywhere in-game the powerType and
powerToken will match your custom values. Don't get confused and give a spell in Spell.dbc a custom
cost powerType (eg. a Spell.dbc entry that costs powerType 201). It should instead have cost powerType 4 (HAPPINESS).
Check the worldserver console for errors (scripts get loaded at the end).
If you get UI errors in-game, keep in mind the line number might not be accurate if you have server code and
client code in the same script file. Try subtracting the server-only line count, or split the script
into a server file and client file.


Currently this system has some (minor?) flaws:
- No error speech or text if you fail client-side resource check (not even a "Not enough happiness" message).
- Spells linked in chat simply show the cost as "X Happiness", but it should be possible to alter the tooltip if the
 spell is found in a custom powertype's consumingSpells table.
- The official Blizzard UI function UnitFrameManaBar_UpdateType(manaBar) from UnitFrame.lua is overwritten, which
 I guess is bad form because if the function is overwritten by two different addons, one of them will misbehave.
- A class can't swap between two custom primary resources on the fly (like a druid swapping between mana, energy, rage)
 because the custom resource is using Happiness and MaxHappiness to store values. You would need to store extra values
 somewhere and change how unitframes set their manabar and change how spells' usable status is determined.

Hello, i'm trying to make hunter have POWER_FOCUS instead of mana, do you know where lines i need to change? i tried many changings on unit.cpp already and none worked :/
