Explore the properties you can use to configure how 2D Physics Core draws and edits physics objects in the Scene view. These properties apply to every project you open in the Unity Editor.
Note
This documentation is about using Pose, Area, and Constraint components. To use 2D physics in the Unity Editor using components like the Rigidbody 2D component, refer to 2D physics instead.
To open these properties, go to Edit > Preferences > 2D > Physics Core.
For more information about the tools these properties configure, refer to Visualize and edit 2D Physics Core scenes.
General
Property | Description |
|---|---|
| Confirm Scene Asset Edit | Displays a confirmation dialog when the Scene view tools edit geometry that a shared asset stores. |
| Edit on Selection | Enables Unity automatically entering the Physics Area or Physics Constraint editing tool when you select a component that has one. If a GameObject has both, Unity enters the Physics Area tool. |
| Hierarchy Selection | Determines which objects Unity selects when you select a GameObject in the Hierarchy window. The options are:
|
| Edit Shape Selection | Sets which layers to edit when you click on a shape. The options are:
|
| Play Mode Edit | Sets which components you can edit in Play mode, in the Inspector window and with the Scene view tools. |
| Local Geometry Target | Sets which values Unity updates when you drag the center handle of a component without a shared geometry asset. The options are:
|
| Asset Geometry Target | Sets which values Unity updates when you drag the center handle of a component that uses a shared geometry asset. The options are:
|
| Geometry Display | Sets how Unity displays the panel beneath a geometry asset in the Inspector window of a component. The options are:
|
| Definition Display | Sets how Unity displays the panel beneath a definition asset in the Inspector window of a component. The options are:
|
| Max Handles | Sets the maximum number of vertex handles Unity displays on a contour in the Scene view. Use a lower value to make editing a complex contour faster. |
| Handle Size | Scales the editing handles in the Scene view. Use a higher value to make handles easier to select. |
| Handle Edge Range | Sets how far from the edge of a selected shape the handles appear, as a multiple of the base handle size. |
| Editing Gizmo Scale | Scales the angle lines, arcs, and limit bands Unity draws when you edit a pose, an anchor, or a limit. This property doesn't affect the handle size. |
| Highlight | Sets the brightness of the selected shape. Set the value to 0 to leave the shape unhighlighted. |
| Dimming | Sets how strongly Unity fades a shape that you haven't selected or hovered over. Set the value to 1 to hide unselected layers. |
Labels
The settings in this section configure the labels Unity displays in the Scene view.
Property | Description |
|---|---|
| Show Labels | Sets when Unity displays coordinates and value labels. The options are:
|
| Label Space | Sets the space that label coordinates use. The options are:
|
| Label Precision | Sets the maximum number of decimal digits in a label. |
Colors
The settings in this section set the color of shapes, handles, labels, and lines in the Scene view.
Shape
Property | Description |
|---|---|
| Invalid Edit | Sets the color of invalid shapes. |
Handle
Property | Description |
|---|---|
| Handle Idle | Sets the color of a vertex, edge, size, or endpoint handle at rest. |
| Handle Hover | Sets the color of a handle when you hover over it. |
| Center | Sets the color of the center handle. |
| Anchor | Sets the color of the anchor handles of a constraint. By default, this color matches Handle Idle. |
| Add | Sets the color of the handles that add geometry. |
| Delete | Sets the color of the handles that delete geometry. |
| Lower Limit | Sets the color of the handle you drag to set a lower limit, such as the lower angle limit of a Physics Constraint Hinge component. |
| Upper Limit | Sets the color of the handle you drag to set an upper limit, such as the upper angle limit of a Physics Constraint Hinge component. |
Labels & Lines
Property | Description |
|---|---|
| Label | Sets the color of coordinate and value labels. |
| Label Background | Sets the color Unity fills behind a label. Set the alpha value to 0 to draw no background. |
| Line | Sets the color of the lines the tools draw between objects, such as the link between the two anchors of a constraint. |
| Zero Reference | Sets the color of the dashed line Unity measures an angle from. |
| Current Angle | Sets the color of the solid line Unity draws out to the handle of the current angle. |
| Edit Fill | Sets the color Unity fills the range with while you edit, such as a swept angle arc or a linear limit band. |
Reset Preferences
Property | Description |
|---|---|
| Reset Preferences | Restores all the properties in the Physics Core tab to their default values. |
