Variant

'Variant' is a type that can be returned from a Lua call in to the API, but cannot be instantiated. This is because a variant gets translated to the correct type when it gets passed to Lua. The types a Variant can be is limited to:

• int
• float
• string
• Colourb
• Colourf
• Vector2f
• light userdata
• nil

So when a function in the API reference claims to return a Variant, it will return one of the above listed types, but there is no way to figure out which type it is unless you know exactly what it is/should be before hand based on its identifier/name.
