Check if a function exists in LUA?

Did you try it?

Works nicely here:

if pcall(function () return type(func) end) then 
   -- exists
   print(type(func))
else 
   -- undefined
   print("undefined")
end

Attention: You need to restart the editor to remove the globals from memory.

Later add as first line / your function stuff:
func = function () end
