Questions about the use of "if"

[JsonDalao]

Does using more than one "if" in a function cause problems?
Here's the code:
[lua]
function UnitDeath(u)
u=GetTriggerUnit()
local id=GetUnitTypeId()

if id==FourCC("h000") then
Action1(u)
end

if id==FourCC("h001") then
Action2(u)
end

...

if id==FourCC("h060") then
Action60(u)
end

end

No, but use elseif instead to check different cases: Programming in Lua : 4.3.1. A better solution would be to use a switch/case but Lua doesn't have that (nor JASS) but you can 'create' one simply: lua-users wiki: Switch Statement

Thank you.

You can create a table that holds the functions beeing executed when an unit of UnitCode is killed. Inside an deathEvent check if you saved one for that unitCode and if there is execute it.
Could look like that, does not include Setting up the Event.

do
    UnitDeathAction = {} --create the table
    UnitDeathAction[FourCC('Hpal')] = function(unit) --Setup an actionfunction for Paladin Units
        print("Paladin was killed")
    end
 
    function DeathEvent()
        local unit = GetTriggerUnit()
        local unitCode = GetUnitTypeId(unit)
        if UnitDeathAction[unitCode] then --is there a function for this unitCode?
            UnitDeathAction[unitCode](unit) --execute it and give the unit.
        end

    end

end
