draw_animation Return ID ?

[CruWiT]

I want create new animation here is api;
https://lua-api.factorio.com/latest/Lua ... _animation
It says;
"Return value
Id of the render object"
What is this ID mean and where can I found ID number or string?

It's the unique identifier of the object. As the function states, it returns a uint64 (a number) so that ID is a number.
