Movement, Paths, and Terrains
Terrains
Changing the color of a path changes how it displays in the E3D window when it is set to be visible. To cause a visible path to have a color:
Select the path in the WEI Tree In the WEI Inspector pane:
Enter a 1 (true) or a 0 (false) for the Red, Green, and/or Blue color properties Click Apply
Save the environment file
If you create or modify a path in the E3D Editor, and you want that path available for the model, you must save the environment file as discussed in “Saving changes” on page 532.
To store the path (optional)
Notice that, by default, a path does not have a representation in the animation area, but it is listed in the Tree pane at the top right of the window. To store all paths in one location:
In the Tree pane, click and drag the path to within the SimGroup - Paths folder.
Save the environment file.
☞ Paths do not have to be stored in the SimGroup - Paths folder, but it is a good collection point if
you have a lot of paths.
To set the item or moveable entity on the path
There are several ways to set items on a path:
• UsingaTransportorConveyItemblock(Itemlibrary).Anexampleofthis,usingaTrans- port block, is shown in “Select the path” on page 501.
• Animate 3D block (This is an advanced method; see page 558.)
• Usinganequationblock,orprogramwithModLcodeasdescribedintheDeveloperRefer- ence.
Terrains
By default, the Extend3D.mis environment file has only one texture painted on the entire ter- rain floor – the Grid texture. Furthermore, the default terrain is a flat surface. However, terrains can be customized to have contours as well as multiple textures (color and patterns). As intro- duced on page 510, terrains are created and modified using the E3D Editor in Terrain mode.
☞ If there is no texture associate with the terrain, or if the texture cannot be located, the terrain will appear white.
The commands in the Action menu are used in conjunction with the commands in the Brush menu to modify or create custom terrains. As an example, if you select the Add Dirt command, move the cursor to the center of the viewing area, and click the left mouse button, you will be “adding dirt” to the terrain. This will have the effect of creating a small mound under the brushed area. How long you hold down the mouse button effects how much dirt is piled up. Each Action has a different behavior and between them all you have a lot of editing control over the terrain.
To do this, choose the Select command and click the terrain with the left mouse button, select- ing the terrain under the brush. The selection area is indicated by squares (nodes) that are drawn at each point where the brush touches the terrain, turning from outlined to solid. Click-
