The ConsoleSee game console
See in Glossary Window (menu: Window > General > Console) shows errors, warnings and other messages generated by Unity. To aid with debugging, you can also show your own messages in the Console using the Debug.Log, Debug.LogWarning and Debug.LogError functions.
The toolbarA row of buttons and basic controls at the top of the Unity Editor that allows you to interact with the Editor in various ways (e.g. scaling, translation). More info
See in Glossary of the console window has a number of options that affect how messages are displayed.
The Clear button removes any messages generated from your code but retains compiler errors. You can arrange for the console to be cleared automatically whenever you run the game by enabling the Clear On Play option.
You can also change the way messages are shown and updated in the console. The Collapse option shows only the first instance of an error message that keeps recurring. This is very useful for runtime errors, such as null references, that are sometimes generated identically on each frame update. The Error Pause option will cause playback to be paused whenever Debug.LogError is called from a script (but note that Debug.Log will not pause in this way). This can be handy when you want to freeze playback at a specific point in execution and inspect the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary.
Finally, there are two options for viewing additional information about errors. The Open Player Log and Open Editor Log items on the console tab menu access Unity’s log files which record details that may not be shown in the console. See the page about Log Files for further information.
Among other messages, Unity shows warnings about the usage of obsolete API calls in your code. For example, Unity once had “shortcuts” in MonoBehaviour and other classes to access common componentA functional part of a GameObject. A GameObject can contain any number of components. Unity has many built-in components, and you can create your own by writing scripts that inherit from MonoBehaviour. More info
See in Glossary types. So, for example, you could access a RigidbodyA component that allows a GameObject to be affected by simulated gravity and other forces. More info
See in Glossary on the object using code like:
// The "rigidbody" variable is part of the class and not declared in the user script. Vector3 v = rigidbody.velocity;
These shortcuts have been deprecated, so you should now use code like:
// Use GetComponent to access the component. Rigidbody rb = GetComponent<Rigidbody>(); Vector3 v = rb.velocity;
When obsolete API calls are detected, Unity will show a warning message about them. When you double-click this message, Unity will attempt to upgrade the deprecated usage to the recommended equivalent automatically.
To adjust the number of lines that a log entry displays in the list, click the exclamation button, go to Log Entry, and choose the number of lines.
This allows you to set the granularity you want for the window in terms of the amount of context versus how many entries fit in the window.
You can specify how accurate stack trace should be captured when log message is printed to the console or log file.
This is especially helpful when the error message is not very clear, by looking at the stack trace, you can deduct from what engine area the error appears. There are three options for logging stack trace:
You can also control stack trace logging via scripting API. See API reference documentation on Application.stackTraceLogType for more details.
