Library Models
The library model refers to the model example that we add by default. After selecting the model in the library model, you can directly click to insert the model at point 0. The following is an introduction to the use of the library model in two parts.
1. Add library model
Currently, the library model types in Wings Engine include buildings, vehicles, animals, people, roads, facilities, shapes, parametric models, etc. (It is worth noting that although vegetation is in the model library, it is not a library model. We will introduce the usage of vegetation models in a separate document.)
The library model location is as follows:
The position of the library model added to the scene can be modified by manually dragging the coordinate axis or entering the coordinates. It also supports rotating or scaling the model by switching the move/scale button after selecting the model.
The difference between a library model and a pack is that a library model can be copied directly in the scene by holding down “Alt” and dragging the model, while a pack does not support direct copying in the scene.
2. Basic settings
The library model filled in the scene does not support modification of material mapping effects, but supports some basic settings such as position, rotation, and scale.
The following are the settings:
| Configuration items | Description |
|---|---|
| Visible | The model is shown or hidden. |
| Show at night | This setting is disabled by default. You can enable it if you want a model to be displayed only at night. |
| Pickable | By default, all models are selectable in edit mode. When this setting is turned on, it determines whether the model can be selected when playing in full screen or sharing to the web. |
| Position | Select the move button in the upper left corner to move in the direction of the arrow. The position value will change with the movement. You can also adjust the position of the model by modifying the specific position value. |
| Rotation | Select the rotate button in the upper left corner, then select the model to rotate it. The rotation value will change with the rotation. You can also adjust the model by modifying the specific rotation value. |
| Scale | Select the zoom button in the upper left corner, then select the model to zoom in and out. The zoom value will change with the zoom. You can also adjust the model size by modifying the specific size value. |
3. Camera distance detection
It means calculating the distance between an object and the detected object in a 3D scene, and using this as a basis to trigger interaction. Here you can detect whether the object in the drop-down box is close to or far away from the object.
