Check if something is a Vector3 or BasePart

[mejackdaawesome2928 (ergophobia)]

I need to know if the parameter inputted into a function is a basepart or a vector3 value. Im pretty sure :IsA() errors for vector3s and value.X errors for baseparts. is there a way to do this without passing in extra parameters specifying the nature of the value?

You can do this:

if typeof(variable) == "Instance" and variable:IsA("BasePart") then
   -- checks if the variable is an Instance, then if it's a BasePart
   --...
elseif type(variable) == "vector" then -- roblox recently added the "vector" type
   -- you can also use typeof(variable) == "Vector3"
   --...
end

type
typeof

Theoretically, it’s obsolete to check for both the condition typeof(variable) == "Instance" and the condition variable:IsA('BasePart'). If the second condition is true, the first condition will always be true, too. This is because any object of class BasePart is always of the type Instance. A small note for the future intending on improving efficiency and reducing the amount of conditions you’re writing in your code.

typeof(variable) == "Instance" and variable:IsA("BasePart")

This checks if the variable is an Instance first before trying to use IsA; if the variable is a Vector3, it would do Vector3:IsA("BasePart") which would lead to an error

Good point, I didn’t think of that! My bad haha I’ve updated my post and quoted your response in it
