How to access Body by object(pointer) , not ID ?

[finscn]

When I want to access/operate a body by bodyInterface , I need use body.GetID()
Is there an easy to use body object directly ?

I found c++ version could , but there is no API to do that in wasm version.

The idea is that most/all(?) of the operations are available through the body interface. This is done for locking purposes in a multi threaded environment. There is a way to obtain a body from a body ID which involves locking the body, that is indeed not exposed yet because it's not very compatible with how things work in JavaScript (can't put a variable on the stack).

(again if you want to expose this then feel free to send me a PR)

In pure js , function-call and finding-object in a map by a key are expensive , when the number of bodies is very large .
and most games (mobile games & steam games) don't use multi-cores or multi-threads.
So I hop there could be a quick way to access/operate a body-instance directly.

For other users, this is available now under physicsSystem.GetBodyLockInterface().TryGetBody(body_id).
