I can change the size of the mesh by doing this in GDScript:
$"../World/Ocean".get_mesh().size = Vector2(init_w.value, init_h.value)
How do you do this in C#?
There is no GetMesh() function or anything similar
GetNode("World/Ocean").GetMesh() //Doesn't exist
But I see it in the docs, is this function not working?
Bonus: is there a place where I can find what a C#'s GDScript equivalent is?
