Hey guys really need some Help with item casting

[dungdodger]

Hello iv been working on this Item for days its been a lot of fun but i cant seem to get these last two parts working right. Please Help im trying to learn    

Heres my Issue... 

  i made a item (Copy and Pasted stuff till it started working lol ) that Teleports the target away and spawns a pigman  but it will only do this one time  after that it only teleports stuff.. But if i unequip it then requip it  it does Both effects again.

I have NO IDEA why it does this iv just been trying Learn what i can.

 

 Also i cant seem to figure out how to make it uncastable if im under 50 Sanity 

Here is some of what i have tried 

 

local function canteleport(inst, caster, target)
if target then
return target.components.locomotor ~= nil
end
--if caster.components.sanity then
--return (caster.components.sanity.current >= 50)
--end

return true
end

  I added the --out  bc it keeps giving and error about not know the value or sanity or caster i have tried to put it many places or make its own

local function.   but nothing works...  and i have this as a follow up to stop the cast or at least thought it would like it did when i had it as a Weapon or a Book.

 

local function oncast_pig(inst, target, caster, owner)


--Check sanity
if not canteleport(caster) then
if caster.components.talker then
caster.components.talker:Say ("Could_it_be_MY_Hat_is_FREE")
return true
end
end

 

this does not crash the game anymore iv tried  owner target inst   all kinda stuff to make them work but its been days working on this trying to LEARN.. some stuff ahah but still  NOTHING

  Any Help would be much appreciated

 

I can attach some files if need be just let me know what i need to do please  THANKS
