Native通信
Unity调用iOS
https://docs.unity3d.com/Manual/PluginsForIOS.html
- Unity：
using System.Runtime.InteropServices;
// DllImport这个方法相当于是告诉Unity，有一个CallObjCFunc函数在外部会实现。
// 使用这个方法必须要导入System.Runtime.InteropServices;
[DllImport("__Internal")]
private static extern void CallObjCFunc(string funcName);
- iOS
14 extern "C" {
15 void CallObjCFunc(const char* methodName)
16 {
17 SEL selector = NSSelectorFromString([NSString stringWithUTF8String:methodName]);
18
19 if ([Plugin respondsToSelector:selector]) {
20 [Plugin performSelector:selector];
21 }
22 }
23 }
Unity调用Anroid
https://docs.unity3d.com/Manual/PluginsForAndroid.html
https://docs.unity3d.com/cn/2021.1/Manual/AndroidJARPlugins.html
- Unity
//实例化AndroidJavaClass,传入Java类路径
AndroidJavaClass jc = new AndroidJavaClass("ccom.devnn.demo.MyJavaClass")
//如果找不到Java类,返回null
if(jc == null) return;
//调用Java类的getInstance方法获取实例
AndroidJavaObject jo = jc.CallStatic<AndroidJavaObject>("getInstance");
//如果找不到Java方法,返回null
if (jo == null) return;
string param = "Hello,Android!";
string result = jo.Call<string>("test", param); //调用test方法,返回值是字符串。
- Android
package com.devnn.demo;
public class MyJavaClass{
private static MyJavaClass instance=new MyJavaClas();
public static getInstance() {
return instance;
}
public String test(String param) {
return "This message is from Android!";
}
}
iOS调用Unity
//第一个参数：消息的接受者，或者说谁来执行方法
//第二个参数：函数名
//第三个参数：需要传的值
UnitySendMessage(const char * GameObjectName, const char *methodName, const char *msg);//注意，三个参数都是C语言字符串，没有'@'
Android调用Unity
// objectName: Unity 对象的名称
// methodName: Unity 对象绑定的脚本方法名
// message: 自定义消息
UnityPlayer.UnitySendMessage(String objectName, String methodName, String message);
该方法有一个弊端，就是发送消息的方法对应的类，必须要挂载在一个 game object 上。
该方法有一点需要注意，就是在原生触发回调接口的时候，可能跟 Unity 的主线程并不是一个线程，此时需要通知 Unity 主线程执行回调。
