Check object action exists (Lua Script)

function objectActionExists(obj, actionName)
local strActionName = "'" .. actionName .. "' executed"

	if obj:isEmpty() then
		print("Object is null")
		return false
	end

	local act = obj.ObjectActions

	-- iterate through the object list with a for loop...
	for i = 1, #act do
		if act[i]:getName() == strActionName then
		    return true
		end
	end
	return false
end
