Print/Debug.Log is not showing output on Unity Console

Question

I am trying to print a simple statement using C# on Unity Console but i don't know why it is not printing.

Solution 1

If print does not work, Debug.Log will not work either so that's not the problem.

These are the possible reasons why print is not showing in the console:

1.Script is not attached to a GameObject.

2.The GameObject the script is attached to is not Active. Activate it from the Editor.

3.The NumberWizard script is not enabled. Enable the script.

4.The log toggle is not checked.

From your screenshot, both Debug, Warning and Error messages are enabled, so we can exclude what's in 4.

Solution 2

Pressing "Play"

According to this link, print() or Debug.Log, only will work with the following conditions

It seems that the key piece of information I was missing was that Debug.Log writes to the console only when you run the game from within unity by pressing the "play" button above the game view.

I was running my game by pressing Ctrl-B, or pressing "Build & Run" in the Build Settings window. In that case, it will only output to the log file

So you have to hit the play button above the game view, not by using the "Build & Run".

No. This is Unity3D

If print and Debug.Log don't work, probably, your code isn't getting called.

Debug.Log and Print both are not printing on Console. @mindOfAi

[Ahmed Abbas]

System.Console.WriteLine("your string here"); is also not working @Svek

Can you add a breakpoint on your Start() method? Make sure it's getting called.

@Programmer solution works... script is not attached to the object

Yeah, I stated it in my answer that you should make sure the script's attached.

Thanks a lot, it worked. I had to delete the script I created and used the add component to create a new script.

I'm in build 2019.2.17f1 on Win10 Pro and saw that my log toggle (in your step 4) was accumulating messages as the number indicating how many messages are present was increasing, but they were not actually displaying in the console. The same messages would successfully display in my custom in-game console. Restarting Unity fixed the issue. I might report this as a bug to Unity later if I have time, but just an FYI for posterity

Which log file? Player.log? Can't find it there either
