Why does unity not have a main thread?
Because Unity uses a somewhat older subset of .NET, there are some newer threading features and libraries we can’t use out of the box, but the basics are all there. As Almo notes in a comment above, many Unity types are not threadsafe, and will throw exceptions if you try to construct, use, or even compare them off the main thread.
How to not freeze the main thread in..?
I have a level generation algorithm that is computationally heavy. As such, calling it always results in the game screen freezing. How can I place the function on a second thread while the game still continues to render a loading screen to indicate the game is not frozen?
How can I place the function on a second thread?
How can I place the function on a second thread while the game still continues to render a loading screen to indicate the game is not frozen? Update: In 2018, Unity is rolling out a C# Job System as a way to offload work and make use of multiple CPU cores. The answer below predates this system.
Is there a way to use multiple CPU cores in Unity?
Update: In 2018, Unity is rolling out a C# Job System as a way to offload work and make use of multiple CPU cores. The answer below predates this system. It will still work, but there may be better options available in modern Unity, depending on your needs.
Can you use system.random per thread in Unity?
Because Unity use an older version of .NET you can’t use newer features and libraries of threading too. What is more Random and Time static members are not available, so you should use instance of System.Random per thread if you need randomness, and System.Diagnostics.Stopwatch if you need timing info.
How are threads used in multithreading in games?
Multithreading is an ability of processor to execute multiple threads concurently. Each thread execute sequence of programming instructions. So in theory you can achieve better performace of your game by divide more complex operations to smaller pieces and run them in separate threads.
