Add Spell - Is Lua Script

[EndUser 4]

Hello,

I tried this in my fightclass as a spell:

t="raid";
nps=1;
npe=GetNumGroupMembers();
if npe<=4 then
    nps=0;
    t="party";
end;
print(t," ",npe)

 

With the spell settings as:

• Combat only - False
• Not spell, is lua script - True

 

I was hoping it would spam something like:

• "party 0" or "party nil"

 

But instead I get nothing.  Any suggestions on how to make this work?  Eventually I hope to make a fightclass that can detect if I'm in a party or raid, then using the global var "t" have it run a loop for party2, raid1..40, etc.

Well, I figured out that my lua script wasn't working as a spell, but if I used it as a condition then it worked.  Now I'm trying to pass "t" to another 'spell', with the below as a condition:

            <LuaScript>-- Find the unit with the largest health deficit, in range, that is alive, that doesn't have Rejuvenation
print("t ",t)            
m=0;
w=f;
local SpellName = GetSpellInfo("Rejuvenation")
for i=nps,npe do
    if i==0 then
        tt="player"
    else
        tt=t..i
    end;
if UnitExists(tt) and IsSpellInRange(SpellName,tt) and not UnitIsDeadOrGhost(tt) and not UnitBuff(tt,SpellName,nil,"PLAYER") then
        a=UnitHealth(tt) / UnitHealthMax(tt);
        if a&gt;m then
            m=a w=tt
        end
    end
end;

-- Heal the unit with the largest deficit
if m &lt;= .95 then
    CastSpellByName(SpellName, w)
end
</LuaScript>

 

I get nothing, not print, not any action, etc.  Suggestions?

I know it's not optimal, but I got it to work with this now:

            <LuaScript>m=0;
w=f;
local SpellName = GetSpellInfo("Rejuvenation")
for i=nps,npe do
    if i==0 then
        tt="player"
    else
        tt=t..i
    end;
    
    ue=UnitExists(tt) print(ue)
    isir=IsSpellInRange(SpellName,tt) print(isir)
    uidog=UnitIsDeadOrGhost(tt) print(uidog)
    ub=UnitBuff(tt,SpellName,nil,"PLAYER") print(ub)
    
    print("----------------")
    if ue and isir and not uidog then print("TRUE") else print("FALSE") end
    print("----------------")
    
    if ue and isir and not uidog then
        a=UnitHealth(tt) / UnitHealthMax(tt);
        if a&gt;m then
            m=a w=tt
        end
    end
end;

if m &lt;= 1 and not ub then
    CastSpellByName(SpellName, w)
end;
</LuaScript>

 

The part that is driving me crazy - otherwise I like solving puzzles - is that the results are not consistent.  Sometimes it works, then other times it just doesn't.

Hello, you can test your lua script in tab "Tools" > "Development Tools" > past code in textbox and click on "Lua (...)".

Dont use global variables in LUA. Put a "local" in front of every new Variable !

Yea, I've kind of given up on this.  It was a useful exercise.  C# seems to be a more consistent method.
