I’m working on a project prototype where I would love to push entities into separate physics worlds so they can be simulated in groups I’m interested in without interacting with other groups.
Obviously that can be easily achieved by just changing the value of PhysicsWorldIndex component but I need to create the physics worlds first. Documentation link
I found this in the documentation but it’s a solution that allows me only to create physics worlds before compilation/building/running/whatever.
In my project I would need to create these physics worlds dynamically because due to it’s nature at one point in time I might need just one physics world and at some different time 50 of them. Is it possible to create and destroy these Physics Worlds / Simulation Groups dynamically at runtime?
One obvious solution would be to create all the worlds I assume I would need in the way shown in the linked documentation, have them running in the background and just use them when I need them but I just feel like it doesn’t sound like ideal solution and idk what it would do to performance if I were to have 100 Physics Groups running in the background at all times even if empty.
I think you will run into performance issues with that many worlds. I am not sure what you are trying to do but think about using layers or putting all your predictive physics into a second world. If you want to run your sim in real time 50 worlds is probably too many.
