C#, Java, and Cpp Communication in Unity
This post covers four things: How C# calls Java functions in Unity. How Java calls C++ through JNI. How C++ under JNI calls Java. How Java calls Unity’s C#.

For example, in Java: package com.example.jni; public class ExampleJavaClass { // Function with no return value void TestFuncVoid(int a) { /* ... */ } // Function with a return value int TestFuncInt(int a) { /* ... */ } } In CSharp, write it like this: ...
