Which graph is best to use?

In my game all levels represent as platforms. Platform is not smooth (polygon). Platforms are connected by bridges (created dynamically). Could you tell me which graph is better to use for it and how to implement the dynamic addition of paths through bridges?

Hi

A grid graph would work I think.
When a bridge is added you could recalculate that part of the grid.
See documentation on dynamic graph updates.

Thanks for the answer
