Unity Console In Unity

The Console window displays messages from Unity and your scripts. It helps you find errors, track variable values and understand what your game is doing.

• Errors (red): Game-breaking issues that stop something from working.
• Warnings (yellow): Potential problems that might cause issues.
• Logs (white): Information you print with Debug.Log().

Opening the Console

• Method 1: Window -> General -> Console.
• Method 2: Ctrl + Shift + C (Windows) or Cmd + Shift + C (Mac).

The Console usually docks at the bottom of Unity by default.

Console Toolbar Buttons

The top of the Console has several important buttons:

• Clear: Removes all messages.
• Collapse: Groups identical messages and shows count.
• Clear on Play: Clears Console when Play mode starts.
• Error Pause: Pauses the game automatically on errors.
• Filter by Type: Show/hide Logs, Warnings, or Errors.

Clicking on Messages

Click any message in the Console. Unity automatically opens the script at the exact line that created it.

• Double-click: Opens script at that line.
• Right-click: Copy message text or open full stack trace.

Filtering Messages

Use the filter buttons to focus on specific message types:

• Logs: Your debug messages.
• Warnings: Potential issues.
• Errors: Actual problems.

Toggle off Logs to hide them. Only see Errors and Warnings.

Clearing Console from Script

Example:

using UnityEngine;

public class ClearConsole : MonoBehaviour
{
    public void Clear()
    {
        // This only works in Editor
        var logEntries = System.Type.GetType("UnityEditor.LogEntries, UnityEditor");
        var clearMethod = logEntries.GetMethod("Clear");
        clearMethod.Invoke(null, null);
    }
}

Attach to a button for a "Clear Console" button in your game.
