#The most efficient DOTS physics simulation of regular OnTriggerEnter/OnTriggerExit events

Hello everybody! I've recently started exploring DOTS Unity Physics package and I wonder if there's any recommended approach when I want to simulate OnTriggerEnter/OnTriggerExit from default MonoBehaviour physics?

I studied stateful examples from git Physics samples and it seems to me that the easiest way would be just copy stateful related systems and components to my project and using this solution.

My questions are:

  1. Is this considered as the recommended approach?
  2. Is that solution performant enough for larger amount of physical entities (in my case I will have between 500 to 2000 entities with capsule collider and physics enabled)?

Thanks in advance for your answers!

BovineLabs.Core library has a highly optimized stateful events of Unity. it works exactly same as ones from samples, but it's much more efficient under the hood

^ it's basically the same thing except I rewrote it to operate in parallel

The samples runs single thread for processing events so you'll definitely run into performance issues with large entity counts
