We’ve been hard at work improving the updated scripting runtime since our last update. Unity 2018.2 ships with dozens of bug fixes related to the scripting runtime, thanks to all of the great feedback we have received since the .NET 4.x Equivalent scripting runtime became officia...

Unity 2018.1 beta now includes a fully-supported, modern .NET runtime. As the .NET ecosystem continues to evolve, Unity is committed to maintaining feature compatibility with the latest and greatest in the .NET world.

Like many programming languages, C# allows the memory for objects to be allocated on the stack (a small, “fast”, scope-specific, block of memory) or the heap (a large, “slow”, global block of memory). Usually allocating space for an object on the heap is much more expensive than ...

A virtual method call is a call that must be resolved at run time. The compiler does not know which method will be called when it compiles the code, so it builds an array of methods (called the virtual table, or vtable) for each class. When someone calls one of those methods, the...

Modern compilers are excellent at performing many optimizations to improve run time code performance. As developers, we can often help our compilers by making information we know about the code explicit to the compiler. Today we’ll explore one micro-optimization for IL2CPP in som...

The IL2CPP team has a strong test-first development mentality. Much of the code for IL2CPP is written using the practice of Test Driven Development (TDD), and very few pull requests are merged to the IL2CPP code without significant test coverage. Since IL2CPP has a finite (altho...
