It has the basic features expected of an IDE - it allows you to manage groups of files as a project, you can edit multiple files in a tabbed editor, the code is syntax-highlighted. Code completion, symbol browsing, and more. It also features a Lua debugger that allows you to debug your Lua code within any application that uses Lua and can load Lua packages. It is written using the multiplatform WxWidgets toolkit, and runs on multiple platforms, including Windows, Linux and MacOS.</p> + <p>Here's a screenshot of a default ZBS window with the debugger stepping through the code (scaled down):<br /> + <img src="Static/zbs_workspace.png" /></p> + <p>As you can see, you can set breakpoints in the code, inspect variables' values, view the Lua call-stacks.</p> + <p>ZBS is open-source, the sources are on GitHub: <a href="https://github.com/pkulchenko/ZeroBraneStudio">https://github.com/pkulchenko/ZeroBraneStudio</a>. The project's homepage is at <a href="http://studio.zerobrane.com/">http://studio.zerobrane.com/</a>. + + <h2><img src="Static/zbs_logo.png" /> First-time setup</h2> + <p>Since ZBS is a universal Lua IDE, you need to first set it up so that it is ready for MCS plugin development. For that, you need to download one file, <a href="https://raw.githubusercontent.com/pkulchenko/ZeroBranePackage/master/mcserver.lua">mcserver.lua</a> from the <a href="https://github.com/pkulchenko/ZeroBranePackage">ZBS's plugin repository</a>. Place that file in the "packages" folder inside your ZBS's folder. Note that there are other useful plugins in the repository and you may want to have a look there later on to further customize your ZBS. To install them, simply save them into the same folder.</p> + <p>Next you should install the code-completion support specific for MCServer. You should repeat this step from time to time, because the API evolves in time so new functions and classes are added to it quite often. You should have an APIDump plugin in your MCServer installation. Enable the APIDump plugin in the server settings, it's very cheap to keep it enabled and it doesn't cost any performance during normal gameplay. To generate the code-completion support file, enter the <code style="background: #ddd; border: 1px solid #aaa">api</code> command into the server console. This will create a new file, "mcserver_api.lua", next to the MCS executable. Move that file into the "api/lua" subfolder inside your ZBS's folder.</p> + <p>After you download the mcserver.lua file and install the completion support, you need to restart ZBS in order for the plugin to load. If there are no errors, you should see two new items in the Project -> Lua Interpreter submenu: "MCServer - debug mode" and "MCServer - release mode". The only difference between the two is which filename they use to launch MCServer - mcserver_debug(.exe) for the debug option and "mcserver(.exe)" for the release option. If you built your own MCServer executable and you built it in debug mode, you should select the debug mode option. In all other cases, including if you downloaded the already-compiled MCServer executable from the internet, you should select the release mode option.</p> + <p>For a first time user, it might be a bit overwhelming that there are no GUI settings in the ZBS, yet the IDE is very configurable. There are two files that you edit in order to change settings, either system-wide (all users of the computer share those settings) or user-wide (the settings are only for a specific user of the computer). Those files are regular Lua sources and you can quickly locate them and edit them from within the IDE itself, select Edit -> Preferences -> Settings: XYZ from the menu, with XYZ being either System or User.</p> + <p>There is a documentation on most of the settings on ZBS's webpage, have a look at <a href="http://studio.zerobrane.com/documentation.html">http://studio.zerobrane.com/documentation.html</a>, especially the Preferences section. Personally I recommend setting editor.usetabs to true and possibly adjusting the editor.tabwidth, turn off the editor.smartindent feature and for debugging the option debugger.alloweditting should be set to true unless you feel like punishing yourself.</p> + + <h2><img src="Static/zbs_logo.png" /> Project management</h2> + <p>ZBS works with projects, it considers all files and subfolder in a specific folder to be a project. There's no need for a special project file nor for adding individual files to the workspace, all files are added automatically. To open a MCS plugin as the project, click the triple-dot button in the Project pane, or select Project -> Project directory -> Choose... from the menu. Browse and select the MCS plugin's folder. ZBS will load all the files in the plugin's folder and you can start editting code.</p> + <p>Note that although ZBS allows you to work with subfolders in your plugins (and you should, especially with larger plugins), the current mcserver ZBS plugin will not be able to start debugging unless you have a file open in the editor that is at the root level of the MCS plugin's folder.</p> + + <h2><img src="Static/zbs_logo.png" /> Debugging</h2> + <p>You are now ready to debug your code. Before doing that, though, don't forget to save your project files. If you haven't done so already, enable your plugin in the settings.ini file. If you want the program to break at a certain line, it is best to set the breakpoint before starting the program. Set the cursor on the line and hit F9 (or use menu Project -> Toggle Breakpoint) to toggle a breakpoint on that line. Finally, hit F5, or select menu Project -> Start Debugging to launch MCServer under the debugger. The MCServer window comes up and loads your plugin. If the window doesn't come up, inspect the Output pane in ZBS, there are usually two reasons for failure:<ul> + <li>Your code in the currently open file has a hard syntax error. These are reported as "Compilation error" in the Output pane, double-click the line to go to the error</li> + <li>ZBS cannot find the MCServer executable. Make sure you are editting a file two levels down the folder hierarchy from the MCS executable and that the MCS executable is named properly (mcserver[.exe] or mcserver_debug[.exe]). Also make sure you have selected the right Interpreter (menu Project -> Lua Interpreter).</li> + </ul></p> + <p>Once running, if the execution hits a breakpoint, the ZBS window will come up and a green arrow is displayed next to the breakpoint line. You can step through the code using F10 (Step Into) and Shift+F10 (Step Over). You can also use the Watch window to inspect variable values, or simply hover your mouse over a variable to display its value in the tooltip. Use the Remote console pane to execute commands directly *inside* the MCServer's plugin context.</p> + <p>You can also use the Project -> Break menu item to break into the debugger as soon as possible. You can also set breakpoints while the MCS plugin is running. Note that due to the way in which the debugger is implemented, MCS may execute some more Lua code before the break / breakpoint comes into effect. If MCS is not executing any Lua code in your plugin, it will not break until the plugin code kicks in again. This may result in missed breakpoints and delays before the Break command becomes effective. Therefore it's best to set breakpoints before running the program, or while the program is waiting in another breakpoint.</p> + </div> + </body> +</html> diff --git a/MCServer/Plugins/APIDump/Static/zbs_logo.png b/MCServer/Plugins/APIDump/Static/zbs_logo.png Binary files differnew file mode 100644 index 000000000..c8d6d6278 --- /dev/null +++ b/MCServer/Plugins/APIDump/Static/zbs_logo.png diff --git a/MCServer/Plugins/APIDump/Static/zbs_workspace.png b/MCServer/Plugins/APIDump/Static/zbs_workspace.png Binary files differnew file mode 100644 index 000000000..9ce17e35a --- /dev/null +++ b/MCServer/Plugins/APIDump/Static/zbs_workspace.png diff --git a/MCServer/Plugins/APIDump/UsingChunkStays.html b/MCServer/Plugins/APIDump/UsingChunkStays.html new file mode 100644 index 000000000..d3ecc6674 --- /dev/null +++ b/MCServer/Plugins/APIDump/UsingChunkStays.html @@ -0,0 +1,167 @@ +<!DOCTYPE html> +<html> + <head> + <title>MCServer - Using ChunkStays</title> + <link rel="stylesheet" type="text/css" href="main.css" /> + <link rel="stylesheet" type="text/css" href="prettify.css" /> + <script src="prettify.js"></script> + <script src="lang-lua.js"></script> + <meta charset="UTF-8"> + </head> + <body> + <div id="content"> + <h1>Using ChunkStays</h1> + <p> + A plugin may need to manipulate data in arbitrary chunks, and it needs a way to make the server + guarantee that the chunks are available in memory.</p> + + <h2>The problem</h2> + <p> + Usually when plugins want to manipulate larger areas of world data, they need to make sure that the + server has the appropriate chunks loaded in the memory. When the data being manipulated can be further + away from the connected players, or the data is being manipulated from a console handler, there is a + real chance that the chunks are not loaded.</p> + <p> + This gets even more important when using the <a href="cBlockArea.html">cBlockArea</a> class for reading + and writing. Those functions will fail when any of the required chunks aren't valid. This means that + either the block area has incomplete data (Read() failed) or incomplete data has been written to the + world (Write() failed). Recovery from this is near impossible - you can't simply read or write again + later, because the world may have changed in the meantime.</p> + + <h2>The solution</h2> + <p> + The naive solution would be to monitor chunk loads and unloads, and postpone the operations until all + the chunks are available. This would be quite ineffective and also very soon it would become very + difficult to maintain, if there were multiple code paths requiring this handling.</p> + <p> + An alternate approach has been implemented, accessible through a single (somewhat hidden) function + call: <a href="cWorld.html">cWorld:ChunkStay()</a>. All that this call basically does is, it tells the + server "Load these chunks for me, and call this callback function once you have them all." And the + server does exactly that - it remembers the callback and asks the world loader / generator to provide + the chunks. Once the chunks become available, it calls the callback function for the plugin.</p> + <p> + There are a few gotcha-s, though. If the code that was requesting the read or write had access to some + of the volatile objects, such as <a href="cPlayer.html">cPlayer</a> or + <a href="cEntity.html">cEntity</a> objects, those cannot be accessed by the callback anymore, because + they may have become invalid in the meantime - the player may have disconnected, the entity may have + despawned. So the callback must use the longer way to access such objects, such as calling + <a href="cWorld.html">cWorld:DoWithEntityByID()</a> or + <a href="cWorld.html">cWorld:DoWithPlayer()</a>.</p> + + <h2>The example</h2> + <p> + As a simple example, consider a theoretical plugin that allows a player to save the immediate + surroundings of the spawn into a schematic file. The player issues a command to initiate the save, and + the plugin reads a 50 x 50 x 50 block area around the spawn into a cBlockArea and saves it on the disk + as "<PlayerName>_spawn.schematic". When it's done with the saving, it wants to send a message to the + player to let them know the command has succeeded.</p> + <p> + The first attempt shows the naive approach. It simply reads the block area and saves it, then sends the + message. I'll repeat once more, this code is <b>the wrong way</b> to do it!</p> +<pre class="prettyprint lang-lua"> +function HandleCommandSaveSpawn(a_Split, a_Player) + -- Get the coords for the spawn: + local SpawnX = a_Player:GetWorld():GetSpawnX() + local SpawnY = a_Player:GetWorld():GetSpawnY() + local SpawnZ = a_Player:GetWorld():GetSpawnZ() + local Bounds = cCuboid(SpawnX - 25, SpawnY - 25, SpawnZ - 25, SpawnX + 25, SpawnY + 25, SpawnZ + 25) + Bounds:ClampY(0, 255) + + -- Read the area around spawn into a cBlockArea, save to file: + local Area = cBlockArea() + local FileName = a_Player:GetName() ..

Note that the plugin fails to + do any error checking and if the area isn't read from the world, it happily saves the incomplete data + and says "hey, everything's right", althought it has just trashed any previous backup of the spawn + schematic with nonsense data.</p> + <hr/> + <p> + The following script uses the ChunkStay method to alleviate chunk-related problems.

If you're wondering how the reading could fail + when we've got the chunks loaded, there's still the issue of free RAM - if the memory for the area + cannot be allocated, it cannot be read even with all the chunks present. So we still do need that + check.</p> + + <h2>The conclusion</h2> + <p> + Although it makes the code a little bit longer and is a bit more difficult to grasp at first, the + ChunkStay is a useful technique to add to your repertoire. It is to be used whenever you need access to + chunks that may potentially be inaccessible, and you really need the data.</p> + <p>Possibly the biggest hurdle in using the ChunkStay is the fact that it does its work in the + background, thus invalidating all cPlayer and cEntity objects your function may hold, so you need to + re-acquire them from their IDs and names. This is the penalty for using multi-threaded code.</p> + <script> + prettyPrint(); + </script> + </div> + </body> +</html> diff --git a/MCServer/Plugins/APIDump/WebWorldThreads.html b/MCServer/Plugins/APIDump/WebWorldThreads.html index fc80a6178..ee0b172e6 100644 --- a/MCServer/Plugins/APIDump/WebWorldThreads.html +++ b/MCServer/Plugins/APIDump/WebWorldThreads.html @@ -39,31 +39,31 @@ <h2>Example</h2> The Core has the facility to kick players using the web interface.
