4 Could you show us your code? The Unity Job System allows you to write multithreaded code easily and safely. i am using java . Language ...

If you’re buying a new machine to use Unity, hopefully this provides you a bit more information about whether you should spend a bit extra for those extra couple of cores. By design, Unity strongly discourages the use a threads. 1 Unity ID. Thread Pool and Task Parallel Library . My second attempt was to use the BackgroundWorker system, which pools threads to avoid the setup time. Threads are dangerous, so you have to be very careful when synchronizing things back.

Unity automatically splits the work into chunks of no less than the provided batchSize, and schedules an appropriate number of jobs based on the number of worker threads, the length of the array and the batch size. So if you want to use Threading anyway it normally works to make a copy of the data that your Thread should work on do your thing with it and afterwards copy the data back to unity.
