What to do if vscode lua breakpoint fails

What should I do if the lua breakpoint fails in vscode?

Using VSCode breakpoints to debug Lua tutorial

1. Install Visual Studio Code (vscode) and search and install luaide in the Plug-in Center

2. Configure luach.json

1. Drag the project folder directly into vscode

2. Debug icon in the left column->Settings-> ;Select LuaDebug, and the launch.json file will appear

3. Find the exePath field in the launch.json file and modify it to the simulator path

For example : "exePath": "D:/xxx/player-3.x/player3.exe",

Just configure the default in other places.

三.lua breakpoint debugging configuration

1. Download the file LuaDebug.lua

Address: https://github.com/k0204/LuaIde

2. Place the LuaDebug.lua file in the project src directory

3. Add debugging code

Add the following code in the main.lua file:

        local breakInfoFun,xpcallFun = require("LuaDebug")("localhost", 7003)
           
            --3.x
            --1.断点定时器添加
            cc.Director:getInstance():getScheduler():scheduleScriptFunc(breakInfoFun, 0.3, false)
            --2.程序异常监听
            function G__TRACKBACK(errorMessage)
            debugXpCall();
            print("----------------------------------------")
            local msg = debug.traceback(errorMessage, 3)
            print(msg)
            print("----------------------------------------")
            end
            local status, msg = xpcall(main, G__TRACKBACK)
            --如果是2.x
            CCDirector:sharedDirector():getScheduler():scheduleScriptFunc(breakInfoFun, 0.3, false)
            function G__TRACKBACK(errorMessage)
            debugXpCall();
            print("----------------------------------------")
            local msg = debug.traceback(errorMessage, 3)
            print(msg)
            print("----------------------------------------")
            end
            local status, msg = xpcall(main, G__TRACKBACK)

##4. Debugging:

1. Press F5 to start debugging

Debugging Once started, the debug command bar will be displayed at the top of the editor

Continue/Pause F5

Skip F10

Enter F11

Exit Shift F11

Restart unassigned

Stop debugging Shift F5

2. Click the debug icon in the left view bar of VS Code to open debugging view.

3. Some debugging tips

1 The variable area can not only visually see the value, but also directly edit the variable value for debugging, or hover the mouse Edit on the source code in the editor.

2 If you want to keep tracking a certain variable, you can edit that variable into the monitor.

3 Using the call stack, you can know who made the error when the error function was called. By looking at it layer by layer, you can sometimes guess the cause of the error.

4 When the source code is not available but the function name is known, you can create a breakpoint function by pressing at the head of the breakpoint area.

5. Edit user code snippets (Snippets)

Menu bar->File->Preferences->User code snippets-> lua

Parameter explanation:

prefix : This parameter is a quick entry to use the code segment. For example, the log here will have intelligent perception when inputting the log during use. .

body : This is the main body of the code segment. The code that needs to be set is placed here. If there are line breaks between strings, use \r\n newline characters to separate them. Note that if the value contains special characters, they need to be escaped. .

Multi-line statements are separated by,.

$1 : This is the position of the cursor.

$2 : After using this parameter, a new line will start at the next position of the cursor. Press the tab key to quickly switch. You can also have $3,$4,$5....
