Hierarchical debug menu system for Unity that makes it easy to create intuitive and organized debug menus.
In general, many debug commands are created during game development, and the number of them increases as development progresses. As a result, it becomes difficult to find the desired command, which in turn leads to a decrease in development efficiency.
Unity Debug Sheet allows you to easily create a debug menu with a hierarchical structure. Its GUI can be easily and intuitively controlled by anyone, especially on mobile platforms.
Of course, it also supports vertical layout.
Adding debug commands is also easy.
// Label
AddLabel("Example Label");
// Button
AddButton("Example Button", clicked: () => { Debug.Log("Clicked"); });
// Switch
AddSwitch(false, "Example Switch", valueChanged: x => Debug.Log($"Changed: {x}"));
// Slider
AddSlider(0.5f, 0.0f, 1.0f, "Example Slider", valueChanged: x => Debug.Log($"Value Changed: {x}"));You can try the demo by cloning this repository itself and playing the demo scenes. The following demo scenes are available.
Character Viewer: CharacterViewerDemo.unity
This demo allows you to switch between character models, motions, etc. from the debug menu. It also include samples that integrate with other libraries such as Graphy and In-Game Debug Console to monitor performance.
Default Cells: DefaultCellsDemo.unity
This demo allows you to check the behavior of all the cells (generic name for items such as button, labels, and sliders, etc.) that are included in this library by default.
Custom Cells: CustomCellsDemo.unity
In addition to the default cells, you can create your own custom cells. This demo shows how to create custom cells.
Entry Scene: DemoEntry.unity The above three scenes can also be transitioned from the this scene. You can see how the debug sheet placed in each scene behaves as singleton.
This tool is compatible with the following environments.

}This section shows an easy way to set up and use the Unity Debug Sheet.
First, drag and drop the prefab named DebugSheetCanvas to Hierarchy window to place it in the scene. And if EventSystem not exists, create it.
Next, create a page for debugging.
Create the page by inheriting from DebugPageBase as shown below.
The following is an example page with a single button that logs Clicked when clicked.
using System.Collections;
using UnityDebugSheet.Runtime.Core.Scripts;
using UnityEngine;
public sealed class ExampleDebugPage : DebugPageBase
{
protected override string Title { get; } = "Example Debug Page";
public override IEnumerator Initialize()
{
// Add a button to this page.
AddButton("Example Button", clicked: () => { Debug.Log("Clicked"); });
// Shen you added any item, call Reload().
Reload();
yield break;
}
}Next, add a link to transition to the debug page created above.
Get the root page and add a link button to it as shown below.
using UnityDebugSheet.Runtime.Core.Scripts;
using UnityEngine;
public sealed class DebugSheetController : MonoBehaviour
{
private void Start()
{
// Get or create the root page.
var rootPage = DebugSheet.Instance.GetOrCreateInitialPage();
// Add a link transition to the ExampleDebugPage.
rootPage.AddPageLinkButton<ExampleDebugPage>(nameof(ExampleDebugPage));
// You must call Reload() after adding cells.
rootPage.Reload();
}
}NOTE If you want to use your own page as the root page instead of linking as above, use
Initialize<ExampleDebugPage>()instead ofGetOrCreateInitialPage().AddPageLinkButton<ExampleDebugPage().
The debug menu can be opened and closed by flicking up and down along the edge of the screen. On the actual device, the area extends from the edge of the screen to approximately 6mm within the safe area. In the demo scene, the red band is displayed in this area to visualize flickable range.
This behavior can be changed from the Global Control Mode on the Debug Sheet component.
You can enable only the left or right side of the screen, or disable flick operation.
Warning In the Unity editor, this range is not necessarily 6mm because it simulate the resolution of the actual device. It is recommended to also use the operation with keyboard shortcuts described below.
You can use keyboard shortcuts to open and close the debug menu. In default, Control (Command on Mac) + Shift + D toggles the debug menu. Shortcuts can be freely changed from Keyboard Shortcut on the Debug Sheet component.
And you can also open/close the debug menu from your script as below.
// These scripts are attached on the GameObject "DebugSheetCanvas > Drawer".
StatefulDrawer drawer;
StatefulDrawerController drawerController;
// Toggle debug sheet.
var isClosed = Mathf.Approximately(drawer.Progress, drawer.MinProgress);
var targetState = isClosed ? DrawerState.Max : DrawerState.Min;
drawerController.SetStateWithAnimation(targetState);With the implementation up to this point, you can confirm that the debug menu works as follows.
This section describes the basic usage of the Unity Debug Sheet. The Quick Start section is the prerequisite, so please read it first.
In default, you can use the following cells.
| Cell Name | Method Name to Add | Description |
|---|---|---|
| Label | AddLabel | Used to display strings. |
| Button | AddButton | Used to trigger actions when clicked. |
| Switch | AddSwitch | Used to switch ON and OFF. |
| Slider | AddSlider | Used to specify a numerical value within a range. |
| Picker | AddPicker | Used to select one of several options. |
| Enum Picker | AddEnumPicker | Used to select one of the elements of the enum. |
| Multi Picker | AddMultiPicker | Used to select more than one from multiple options. |
| Enum Multi Picker | AddEnumMultiPicker | Used to select more than one from the elements of the enum. |
| Page Link Button | AddPageLinkButton | Used to transition to the other debug pages when clicked. |
You can check the behavior of each cell by playing the Default Cells Demo Scene. You can also create your own cells. See the Custom Cells section for more information about this.
Using CellModel, you can update the contents of the cell that has been generated. The following is an example of renaming a generated button each time the Space key is pressed. Please refer to the comments for details.
using System.Collections;
using UnityDebugSheet.Runtime.Core.Scripts;
using UnityDebugSheet.Runtime.Core.Scripts.DefaultImpl.Cells;
using UnityEngine;
public sealed class ExampleDebugPage : DebugPageBase
{
private int _buttonCellIndex;
private ButtonCellModel _buttonCellModel;
private int _counter;
protected override string Title => "Example Debug Page";
public override IEnumerator Initialize()
{
// Create the CellModel and set data and events.
var buttonCellModel = new ButtonCellModel(false);
buttonCellModel.CellTexts.Text = GetButtonName();
buttonCellModel.Clicked += () => { Debug.Log("Clicked"); };
// Keep the index of the cell and the CellModel.
_buttonCellIndex = AddButton(buttonCellModel);
_buttonCellModel = buttonCellModel;
Reload();
yield break;
}
private void Update()
{
if (Input.GetKeyDown(KeyCode.Space))
{
// Update the cell data
_counter++;
_buttonCellModel.CellTexts.Text = GetButtonName();
// Refresh the target cell.
RefreshDataAt(_buttonCellIndex);
// You can also refresh all data by calling RefreshData().
//RefreshData();
}
}
private string GetButtonName()
{
return $"Example Button {_counter}";
}
}In default, DebugSheetCanvas is used as a singleton. That is, if DebugSheetCanvas is placed in two scenes, the one instantiated first will be used and the one loaded later will be destroyed.
In this case, initialization should be only be done on the first DebugSheet.
If the order of scene loading is not guaranteed, you can use DebugSheet.GetOrCreateInitializePage() to get a page that has already been initialized, if any, and initialize it.
Please refer to the DemoEntry scene for the workflow in multiple scenes.
Note that if you do not want to use it as singleton, you can do it by unchecking Singleton in the DebugSheet component.
You should exclude GameObject, script files, and resources files related to the debug menu from the release builds.
You can exclude all scripts of the Unity Debug Sheet by adding EXCLUDE_UNITY_DEBUG_SHEET to the Scripting Define Symbols in the Player Settings.
Thus, if you enclose all your own code that accesses the Unity Debug Sheet with #if EXCLUDE_UNITY_DEBUG_SHEET, you can exclude all the code from the release builds.
It may also be a good idea to combine your own scripts that accesses the Unity Debug Sheet into a single assembly and set Define Constraints in the asmdef.
In addition, you can completely exclude the debug menu from your build by doing the following.
- Delete the Resources folder containing the debug menu resources if you have created.
- Delete the GameObject containing the DebugSheet component in your scenes.
To create your own cell, first create a component that inherits from Cell and a model that inherits from CellModel to set data to it.
using UnityDebugSheet.Runtime.Core.Scripts;
using UnityEngine;
using UnityEngine.UI;
public sealed class CustomTextCell : Cell<CustomTextCellModel>
{
[SerializeField] private Text _text;
[SerializeField] private LayoutElement _layoutElement;
private const int Padding = 36;
protected override void SetModel(CustomTextCellModel model)
{
_text.text = model.Text;
_text.color = model.Color;
_layoutElement.preferredHeight = _text.preferredHeight + Padding;
}
}
public sealed class CustomTextCellModel : CellModel
{
public string Text { get; set; }
public Color Color { get; set; } = Color.black;
}Then, create a GUI, attach this component to it, and make it a prefab. Due to the implementation of the cell recycling system, the following points should be taken into account when implementing the cell.
- Attach a Layout Element to the root GameObject and input a height in the Preferred Height property.
- Set the width of the cell to a fixed value.
Next, set this cell to Cell Prefabs on the Debug Sheet.
All that remains is to add this cell to the page. Please refer to the demo scene of the custom cells for the actual implementation.
In default, the black GUI is displayed as the backdrop of the debug menu. You can hide it if you want by deactivating the GameObject of DebugSheetCanvas > Backdrop.
In default, the debug menu is closed when the backdrop is clicked. You can disable this behavior by unchecking Close When Backdrop Clicked in the Stateful Drawer Backdrop Controller component attached to the DebugSheetCanvas > Drawer.
You can change the Show/Hide animations by changing the AnimationDuration and AnimationCurve properties in the Stateful Drawer component attached to the DebugSheetCanvas > Drawer.
By default, the debug menu appears from outside the screen, and is placed outside the screen when it is hidden. You can work it within the safe area by checking Move Inside Safe Area property in the Debug Sheet Drawer component attached to the DebugSheetCanvas > Drawer.
You can also change the min/max size of the debug menu. If you changed this, it can always be displayed at the bottom of the screen, even when minimized, as shown below, for example.
To change the size of each state, edit the properties of the Debug Sheet Drawer attached to Debug Sheet Canvas > Drawer. Adjust the Min's Progress to change the size shen minimized and Size to change the size when maximized. Middle is the middle size applied when held vertically.
You can apply and check the size of each state by clicking Set State button in Debug area.
Unity Debug Sheet consists of uGUI, so you can freely customize the look by adjusting the properties.
- Color of the back and close buttons
- Color of the backdrop
- Text color of the title
The design of each cell can be freely customized by creating a custom cell. See the Custom Cells section for more information on this.
