Full AOT compilation is not supported by Mono on all platforms. Last time I investigated (years ago...) it was supported on amd64, but not x86. So you can perform these tests on 64-bit Intel-based...

Multiply the quaternion by an Euler rotation quaternion like this: transform.rotation = Quaternion.LookRotation(hit.normal) * Quaternion.Euler(0, 0, zAngle); You can also specify a custom "up" axis to...

Try using axis 9 and axis 10 to read the triggers. This has worked for me in the past, but I think I heard that it doesn't work properly when you have multiple Xbox360 pads connected to the same PC....

You can use the underlying iterators without creating the unnecessary garbage - essentially, you write what you would have liked the compiler to generate for you. The basic pattern is: var enumerator =...

Regarding interpolation and extrapolation, you're right, if the physics frame rate is high then you won't notice much difference. One time when you will particularly notice a difference is if you...

One rule of thumb for reusable, library-style classes is that private methods can make assumptions about internal state and/or the state of arguments, because their callers know everything, but public...

This is not great, but you could set each sprite renderer's "order in layer" property dynamically based on the Y coordinates, and reserve Z coordinate changes for sorting within a character. I don't...
