Protagonist Spell Only Options

[Rabain]

I want to create a spell that only the protagonist can cast. If anyone else tries to cast it they will get a message.

So far I have tried casting a spell that sets a global. In a script if have the following:

CODE

IF
    Global("PConly","GLOBAL",1)
    Class(Player1,MAGE_ALL)
    IsActive(Player1)
THEN
    RESPONSE #100
        ActionOverride(Player1,ForceSpellRES("MyPConlyspell",Myself))         ActionOverride(Player1,DisplayStringHead(Myself,8538))
        SetGlobal("PConly","GLOBAL",2)
END

Ignore the DisplayStringHead..thats just for testing.

What is happening is that even if someone else in the party casts the first spell my Player1 starts casting "MyPConlySpell"

I can't seem to find a valid script command that specifies PC only.

I will also need a command that will work if someone not the PC casts the spell. I can use this in a second script block.
