我们底层库不支持某种数据类型

we want to share our shader code with both directX and openGL.
Right now, we have to write separate almost identical shader files for directX and openGL.

PhysX and bullet are both open source.

Integrate physics engine into our API

• add npl.bat and npls.bat as in ParaCraftSDK that reference the paraengineclient.exe.
• can we add an option in nsi UI to check if we want to install to ENV path (check by default)
• add two program file links for NPL: github wiki web link and npl.bat (which will start the local NPL code wiki site)
• display license file for NPL runtime in installer. Either one is fine.

  • [[https://github.com/LiXizhi/ParaCraftSDK/blob/master/LICENSE]]

optimize the BlockEngine:GetBlockFull(x,y,z) function.

We do the following:

• create a C++ function that returns block_id, block_userdata in one call, such as BlockRegion::GetBlockFullDataByIndex in BlockRegion.cpp
• create a C function and add it using ParaEngineFFI in NPL. When ffi is not available, it can fall back to two calls to standard functions.

this is how to return multiple values in ffi:

• 基础功能制作

• 制作Demo文件并更新WIKI文档

支持一个可以隐藏某类型方块的接口

只隐藏方块本身的显示，其余逻辑保持原本的样子

思路：
1.将BlockTemplate临时设置为transparent & invisible
2.rebuild all renderable chunks to take effect.
3.better remove aabb for mouse picking

请问我可以使用Canvas3D设计出类似3D设计器中三视图的功能吗？我们需要类似于3Dmax，maya或者unity中编辑器的三视图界面，3D坐标系显示和地上的网格功能，左侧显示俯视图，正视图和左视图，右侧显示3D视角，当主视角旋转时三视图中对应画面要联动。

NPL IPC debugger package for vs plugin will crash visual studio, if NPL web debugger is running simultanously.

通过使用python+clang分析c++代码， 自动化的生成Lua bing代码

实现目标

1. 开发人员实现功能的时候， 绝大部分情况下不需要考虑lua bind的事情（部分特殊优化例如ffi代码需要手工实现lua bind）
2. 减少模版的使用， 降低exe文件大小
3. 生成的lua bind代码完全基于luabind， 保持对现有的规则兼容
4. 透明化包装类， 甚至减少包装类用lightuserdata来实现各种功能
5. 更高效的转换c++ struct和各种std对象， 尽量避免userdata的使用

我调用ide\gui_helper.lua 中的_guihelper.SetUIFontFormat(uiobject, format) 设置了editbox的文本位置format=5，文本居中对齐了但光标却还是左对齐

使用 npl 或 npls 命令执行某个文件时，不应对文件扩展名有限制。

如：当有文件 bin/www 时（www是一个文件名，没有扩展名），会有以下这样的错误：

以前都没遇到过的，今天编译试了2台centos 7 都有如下错误？

compress block engine raw file when saving to disk
Must support old uncompressed file, use a different version number when saving compressed file.

It is too big(1-2MB) to upload to git cloud.

In paracraft, this method is wrong since some NPLRuntime version. Please fix it asap.

you can test with following command

/selectobj

例如：
local a = NPL.load('a');
有文件 npl_mod/a/a.npl
无法加载此文件。
如果将 a.npl 改为 a.lua，则正常。

Just moved movie codec here:

• https://github.com/tatfook/MovieCodecPlugin

Make this a mod project to be uploaded to mods site in keepwork.com
the mod should be an install once mod, meaning that it is loaded only on demand by the C++ engine.

I think it should be a special mod zip file like
Mod/MovieCodecPlugin.zip
Once loaded as an ordinary mod, it will deploy itself and then unload and disabled.

ModBase:SetEnabled(false)
ModBase:ExtractMod()
ModBase:CheckVersion()

使用 npl 或 npls 命令执行一个文件的时候，不要弹出新的窗口。

播放时，bmax模型方块的突然减少，会显得突兀

some xml movie entity file in paracraft can be as large as 1-4MB, which is too large for our git cloud.
The C++ version of ParaIO. read /write xml may optionally support (de)compressing the xml file into zip file without changing the extension.

The reader code can automatically detect if xml is compressed or not. So all we need to change is the npl writer code in Paracraft.

it may be related to wrong mouse x,y delta calculation in relation to windows message.

This is pretty urgent because remote control player's desktop is very common when solving problems on end users' computers or during a remote meeting.

高分辨率的手机或4K电脑，应该将3D渲染到底分辨率Buffer上，再拉伸到全屏。

@kkvskkkk 如题 @hetter 配合手机版测试。

对于高清4K显示器也同样试用。 不然对于Deferred Shading效率太低了。

应用buffer picking 返回的结果是一个整型数据集合。而常规拾取本身期望能获取鼠标当前选中的场景中的对象。

调用代码：
NPL.load("(gl)script/ide/System/Scene/BufferPicking.lua");
local BufferPicking = commonlib.gettable("System.Scene.BufferPicking");
local result = BufferPicking:Pick(nil, nil, 2, 2);

  NPL 支持在一个TCP上跑多个协议的。 @陈鎏 你如果感兴趣， 可以考虑用NPLRuntime C++ to support HTTP2's HPACK, Multiplexing, binary等几个重要功能. 其实NPL目前的协议已经部分实现了HPACK和binary zip compression.

see also :

• http://undertow.io/blog/2015/04/27/An-in-depth-overview-of-HTTP2.html
• https://http2.github.io/http2-spec/#StreamIdentifiers

这个是http2的设计：

• Client--》Server 用32位的奇数
• Server--》Client 用32位的偶数 = 奇数 + 1

这个设计主要是HTTP2 有一个设计是Server Push就是可以预测Client的请求， 主动将数据推送给Client。 比如你访问了index.html, Server预测你一定会需要index.css, 那么Server会主动Push数据给Client. 不需要Client发任何请求

在斜对角的Chunk，没有mark dirty.

最近发现越来越多的fbx文件 读取时有兼容问题， 升级一下assimp看能不能解决这些问题

// we expect all remote NPL runtime's public file list mapping to be identical
int file_id = m_msg_dispatcher.GetIDByPubFileName(file_name.sRelativePath);

这个设计感觉限制性很强啊
LiXizhi 9/27/2016 6:33:56 PM
嗯 这个我一直希望改改。 在建立连接时，同步一下这个表。
刘世峰 9/27/2016 6:34:03 PM
既然都用文件名作publicfile了，为什么不在远程机器上直接激活文件名呢
不需要同步啊 两边各自用各自的表就好了
LiXizhi 9/27/2016 6:34:32 PM
对 是可以做到的。
刘世峰 9/27/2016 6:34:44 PM
双方只需要知道自己关心的那个文件名就好了
相当于一个接口名
LiXizhi 9/27/2016 6:35:07 PM
是这样的， 为了节约带宽， 实际传的是ID。
发送方需要知道接收方的ID是什么
刘世峰 9/27/2016 6:36:03 PM
传id的限制太大了 两边的上层逻辑不一定一样 那么很可能id就对不上
LiXizhi 9/27/2016 6:36:56 PM
我在设计时， 是希望自动同步ID的。 但是后来一直没有做这里。
刘世峰 9/27/2016 6:37:09 PM
就直接传文件名，每次浪费几十个字节 应该影响不大吧
LiXizhi 9/27/2016 6:37:10 PM
所以NPL的代码中， 你是看不到ID的。
刘世峰 9/27/2016 6:38:02 PM
嗯 自动同步倒也是可以解决问题
LiXizhi 9/27/2016 6:38:52 PM
还是尽量省一点。
刘世峰 9/27/2016 6:39:27 PM
嗯 也是 毕竟每个message都有这部分

这个功能在聊天，复制链接时非常有用。 我们的默认模版应该支持
