Error Messages: Can They Be Made

[imakunee]

Can you make a custom error message when you try to cast a spell but can't?

Trigger the "can't cast spell" by ordering (Triggering unit) to "stop".

Use SimError to display the message. Source (copy in map custom script header) :

//Needs a udg_SimError global sound variable
function SimError takes player ForPlayer, string msg returns nothing
    if udg_SimError==null then
        set udg_SimError=CreateSoundFromLabel( "InterfaceError",false,false,false,10,10)
    endif
    if (GetLocalPlayer() == ForPlayer) then
        call ClearTextMessages()
        call DisplayTimedTextToPlayer( ForPlayer, 0.52, -1.00, 2.00, "|cffffcc00"+msg+"|r" )
        call StartSound( udg_SimError )
    endif
endfunction

You need a sound-type variable declared using CTRL+B and name it SimError. Then, to display the error message, do :

• //...
  • Set MyPlayerVariable = (Owner of (Triggering unit))
  • call SimError(udg_MyPlayerVariable,"You cannot cast that on mechanical units !")
