Rather than injecting code, the Mono scripting backend uses platform specific signaling mechanism to handle these same runtime checks. These three runtime checks are all guarantees provided by the. The ArrayElementTypeCheck code will thrown an ArrayTypeMismatchException if the type of the element being added to the array is not correct.

The IL2CPP_ARRAY_BOUNDS_CHECK code will throw an IndexOutOfRangeException if the array index is not correct.The NullCheck code will throw a NullReferenceException if the value of the array is null.The three runtime checks are not present in the IL code, but are instead injected by il2cpp.exe. Store the boxed value in the array at index 0 Here are three important runtime checks Object_t * L_3 = Box(InitializedTypeInfo(&Single_t264_il2cpp_TypeInfo), &L_2) Box the float instance, since it is a value type. Throw new InvalidOperationException('Don't panic')

Public class HelloWorld : MonoBehaviour ', importantData.InstanceIdentifier) This time, it has the following contents: As in the first post in this series, I’ll start with an empty project and add one script file. I’ll use the latest version of Unity available, 5.0.1p1, for this example. Still, the concepts will remain the same. We will get into some very version-specific code that is certainly going to change in later versions of Unity. NET virtual machine, see how loops are generated and more! Along the way, we will see how managed types are represented in native code, take a look at runtime checks used to support the.

In this post, we will investigate the C++ code generated by il2cpp.exe. This is the second blog post in the IL2CPP Internals series.
