pre-task

• double click any CSharp script in the project on Unity editor
  • then, Visual Studio with the project gonna be open
• now, you have Unity editor and Visual Studio open

start-debug

• there are two ways to starting to debug Unity with Visual Studio

• way #1
  • click Attach to Unity in Visual Studio
  • click Play in Unity editor

• way #2
  • change from Attach to Unity to Attach to Unity and Play
  • click Attach to Unity and Play
• when you follow either of the ways, Unity and Visual Studio are connected
  • and you are ready to debug the game in Visual Studio

break-point

• it is possible to use breakpoints as usual debugging in Visual Studio

• I put a breakpoint in the statement for checking whether the if statement works
• and started debugging as following some way above

• when player gets an item, game gets paused
  • and the breakpoint in Visual Studio is activated
• in this situation, you can find which variable has some value from Visual Studio
  • as usual debugging with breakpoint

• when you wanna resume the game, click Continue in Visual Studio
  • then, the game in Unity editor gets resumed

• even you can add or remove breakpoint during debugging the game
  • I've removed first breakpoint and added second breakpoint in the statement
  • when player gathers all item, the breakpoint would be activated

precaution

• when you start debugging following way #2, there is one caution you should be care
  • if you edit some CSharp script in Visual Studio, you should click Unity editor
  • then, Unity detects the changes and compiles your CSharp script into some dlls such as Assembly-CSharp.dll
    (when Unity editor doesn't respond, it does the compilation)
• in other way, way #1, you will have to click Unity editor
  • so automatically this problem gets solved
