Performance with continuous collision detection

Unity Engine

I’m debating enabling continuous collision detection on some obects. I’m just not sure if doing so will have a big impact on performance on the device. I’m having an issue with an object passing through others when its not supposed to, but it doesn’t happen to often so maybe its not worht it. I would have one obect set to continuous dynamic and the rest to just continuous. My only concern is that I sometimes have a lot of these objects on screen at a time. Sometimes up to a hundred.

Is it a bad idea to enable continuous collision on these obectsif there’s going to be that many? Also, right now only the object that would be dynamic has a rigid body. The rest do not. I would have to add a rigid body to all of them as well. Would that also be a big performance hit even if the are kinimatic?

Thanks for any insight on the topic

Using continous collision detection on iOS with a 100 objects is probably very much overkill.

Best profile the worst case and see if it makes a big difference. But i would think that it’s not a good idea performance wise.

well, I tried it out and I actually didnt see much decrease in performance at all, but It did create a big problem. I’m going to create a different post about it.
