Descripción

Custom 3D GUI controls and drawing in the scene view.

Handles are the 3D controls that Unity uses to manipulate items in the scene view. There are a number of built-in Handle GUIs, such as the familiar tools to position, scale and rotate an object via the Transform component. However, it is also possible to define your own Handle GUIs to use with custom component editors. Such GUIs can be a very useful way to edit procedurally-generated scene content, "invisible" items and groups of related objects, such as waypoints and location markers.

You can also supplement the 3D Handle GUI in the scene with 2D buttons and other controls overlaid on the scene view. This is done by enclosing standard Unity GUI calls in a Handles.BeginGUI / EndGUI pair within the //OnSceneGUI// function. You can use HandleUtility.GUIPointToWorldRay and HandleUtility.WorldToGUIPoint to convert coordinates between 2D GUI and 3D world coordinates.

lightingAre handles lit?
matrixMatrix for all handle operations.
secondaryColorSoft color to use for for general things.
selectedColorColor to use for the currently active handle.
xAxisColorColor to use for handles that manipulates the X coordinate of something.
yAxisColorColor to use for handles that manipulates the Y coordinate of something.
zAxisColorColor to use for handles that manipulates the Z coordinate of something.

Variables

currentCameraSetup viewport and stuff for a current camera.

Funciones Estáticas

ArrowCapDraw an arrow like those used by the move tool.
BeginGUIBegin a 2D GUI block inside the 3D handle GUI.
ButtonMake a 3D Button.
CircleCapDraw a camera-facing Circle. Pass this into handle functions.
ClearCameraClears the camera.
ConeCapDraw a Cone. Pass this into handle functions.
CubeCapDraw a cube. Pass this into handle functions.
CylinderCapDraw a Cylinder. Pass this into handle functions.
DiscMake a 3D disc that can be dragged with the mouse. Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
