Is that possible to use only collision detection part from bepuphysics and not to create simulation and etc?

[tzngit]

My scenario is as follow:
There is a battle n client side.let's say I have some object which in usual shapes that are moving around on a plane, and at last when battle's over some data used to describe battles would upload to my server as some sort input to a server side battle-result-verify program.
And here is the question, I already get the 'input' data which could tell me the specific time obj1 collide with obj2 at a specific position,I just want to do a check for that collision detection, so can I use bepuphysics just as a library and use only collision detection function?

There unfortunately isn't a demo about it, and it requires a bit more schlep, but yes.

Two top-level ways you could go about doing this:

1. If you wanted to maintain more of the Simulation-ish API, you could create a custom ITimestepper that just doesn't invoke the unneeded parts of the Simulation. See DefaultTimestepper for the ... default timestepper.
2. You can also just throw out ~everything and use only the BroadPhase, or even just a Tree directly if you wanted to trim even more. You'd then decide how you want to handle pair generation and pair processing. The CollisionBatcher<T> would be the way you generate contacts from the pairs found by Tree tests. You can see examples of its use in the NarrowPhase, or in a simpler context, the CollisionQueryDemo.
