A way to make UE5 HotReload from vscode under Linux

Development Programming & Scripting C++

If you build your project within vscode under Linux, you should noticed that the UE5 does not Hot Reload the newly c++ code.

And after some researches, I found a solution to resolve this issue.

First, You need install the vscode extension.

Then, Generate vscode project file

And edit your .vscode/tasks.json file

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "MyProjectEditor Linux Development Build",
      "group": "build",
      "command": "Engine/Build/BatchFiles/Linux/Build.sh",
      "args": [
        "-ModuleWithSuffix=${workspaceFolderBasename},${input:randomNumber}", // Add this line
        "MyProjectEditor",
        "Linux",
        "Development",
        "/Ly/code/games/MyProject/MyProject.uproject",
        "-waitmutex"
      ],
      "problemMatcher": "$msCompile",
      "type": "shell",
      "options": {
        "cwd": "/Ly/apps/unreal-engine"
      }
    }
  ],
  "inputs": [ // And add this field
    {
      "id": "randomNumber",
      "type": "command",
      "command": "shellCommand.execute",
      "args": {
        "command": "echo $(( ( RANDOM % 1000 ) + 1000 ))"
      }
    }
  ]
}

After these steps, hot reload should works perfectly.
This works for me with UE_5.1.1 under Arch Linux
Let me know if you have any other issue.
Sorry, my English is not good.
