Gizmo for Activity default 3D object
The Gizmo
Once you have selected an object in the window, it will appear with a three-axis (XYZ) device drawn through it. This device (called a Gizmo) is a tool for translation (movement), rotation, or scaling of the selected object.
Each axis arm has a different colored line: red (X), green (Y), and blue (Z). If you hover the mouse over one of the axis arms, it highlights in a yellow color. The object can then be moved in that direction.
Using the Gizmo to move and perform other tasks on objects is described in the chapter “3D Objects” that starts on
page 513.
☞ The axes of the Gizmo are expressed in terms of the object, not necessarily the E3D world. If an object is placed in the E3D window in its default orientation, the axes will be pointing in the same direction as the compass for the E3D window. However, if you rotate the object by 90 degrees, for example, the Gizmo’s axes will be 90 degrees out of sync with the E3D window’s compass.
Modifying object properties
You can change a selected object’s properties by editing values the block’s dialog (if the object corresponds to a block in the model), changing property values in the Inspector pane, or by using ModL code. If you make a change to one of the properties in the Inspector pane, you must click the Apply button at the upper left corner of the pane to apply the change to the object. You can also alter some properties (an object’s position, rotation, or scale) by physi- cally manipulating the object using the Gizmo. Changing object properties is described in the chapter “3D Objects” starting on page 513.
☞ If the 2D block position is linked to the 3D object position, changing the position of the object in the E3D window will change the position of the block in the 2D model.
E3D Editor modes
The E3D Editor has several editor modes that allow you to alter different aspects of the E3D animation area. You can select a mode by either choosing it in the Editor’s Window menu (shown at right) or by pressing the equivalent function key.
If you select a different mode in the Window menu, the panes on the right of the E3D window change and sometimes disappear. These changes are discussed where the respective modes are described.
Mode categories
There are three categories of modes for the E3D Editor:
Window menu: Editor modes
1) World.ThethreeWorldmodes(WorldEditor,WorldEditorInspector,andWorldEditor Creator) are used for inspecting and manipulating objects. They are discussed in “World modes” on page 508.
2) Terrain.ThetwoTerrainmodes(TerrainEditorandTerrainTexturePainter)areusefulfor modifying the contours and textures of the terrain. They described in “Terrain modes” on page 510.
