Godot 4 源码分析 - 增加管道通信

news2024/11/24 8:41:02

学习研究Godot 4，很爽，虽然很庞杂，但相对于自己的水平来说，很强大，尤其是vulkan这块直接打包可用，省得自己从头琢磨。

一点一点地消化、优化与完善，最终才能成为自己的。

这段时间就在Godot的基础上，增加管道通信，实现Godot与本机已有程序进行通信，以备后续的无缝集成整合。

其实，Godot支持各种网络通信，支持UDP、TCP等。为什么非要实现管道通信，本质上还是想看看改造效果。最终目标是实现Godot软件与自己的DrGraph软件的管道通信

DrGraph端处理

为实现管道通信，根据Windows命名管道通信原理进行相应模块化实现。

}

实现过程没费劲，就是编译费劲。一直提示相应功能没有实现。原来godot是用scons什么工具编译的，需要配置路径什么的。为省事，避免琢磨scons，我把CbwPipe两个文件放在已有目录下就OK了。

GDScript支持

在源码中增加了功能，肯定是希望在godot项目中使用，比如用GDScript编写脚本时可用

在CharGPT指导下，完成这个功能还算顺利。核心是与ClassDB打交道

class DllStream : public Object {
	GDCLASS(DllStream, Object);
	TDllStream stream;

public:
	DllStream();

	DllStream *rewind();
	DllStream * write(const Variant **p_args, int p_argcount, Callable::CallError &r_error);
	void send_pipe();
};


DllStream::DllStream() {
	ClassDB::bind_vararg_method(METHOD_FLAGS_DEFAULT, "write", &DllStream::write, MethodInfo("write"));
	ClassDB::bind_method(D_METHOD("rewind"), &DllStream::rewind);
	ClassDB::bind_method(D_METHOD("send_pipe"), &DllStream::send_pipe);
}

DllStream * DllStream::write(const Variant **p_args, int p_argcount, Callable::CallError &r_error) {
	for (int i = 0; i < p_argcount; ++i) {
		print_line("DllStream::write(", i + 1, "/", p_argcount, ": type = ", p_args[i]->get_type_name(p_args[i]->get_type()), ", value = ", *p_args[i]);
		switch (p_args[i]->get_type()) {
			case Variant::BOOL:
				stream << bool(p_args[i]);
				break;
			case Variant::INT:
				stream << int(*p_args[i]);
				break;
			case Variant::FLOAT:
				stream << float(*p_args[i]);
				break;
			case Variant::STRING:
				stream << String(*p_args[i]).ptr();		// todo: char32_t的处理
				break;
		}
	}
	return this;
}

DllStream* DllStream::rewind() {
	stream.Rewind();
	return this;
}

void DllStream::send_pipe() {
	TCbwPipe::get_singleton()->WriteDllStream(stream);
}

在godot启动过程中，直接自动发一些管道信息：

std::string pipeName = String2std(p);
OS::get_singleton()->is_pipe_allowed = TCbwPipe::get_singleton()->ConnectToServer(pipeName);
TDllStream dsSet, dsGet;
dsSet << DRSTREAM_FUNCTION_SET
	  << "MainForm"
	  << "Caption"
	  << "godot 标题 Command by DrGraph"
	  << ioFinish;
dsGet << DRSTREAM_FUNCTION_GET
	  << "CurrentForm"
	  << "Caption" << ioFinish;
TCbwPipe::get_singleton()->WriteDllStream(dsSet);
TCbwPipe::get_singleton()->WriteDllStream(dsGet);

在DrGraph软件中接收到管道数据：

 GDScript注册

为了在GDScript中使用，还需要注册类名

GDREGISTER_CLASS(DllStream);

在Script编辑器中，就可以出现代码提示了

相应功能调用

 Godot工程运行后，在界面中操作以触发相应代码功能

 使用触发后，在Godot软件中可看到输出

 DrGraph软件中同步收到管道信息

 达到效果。还有一点小问题，中文乱码，应该是编解码问题，有空再处理一下。
