This tool can be used to spawn any SimObject that is mounted in the {{< glossterm >}}vfs{{< /glossterm >}}. The top of this window is taken up with the following filter options:



-   **Packages** - By default this is set to *All Packages*, but you can filter to any package that is used in the VFS from here.

 

-   **Objects** - This menu lets you select the SimObject to spawn. Depending on the SimObject selected, additional options may be visible.

        alt="Additional Object Menu" >}}
        
    -   **Simple Sim** - If this is checked, the object will be spawned with instructions to use the "simplified" simulation, which is what is used by passive aircraft.
    -   **Create WASM** - If this is checked, the SimObject will be spawned with a flag to use WebAssembly modules. It should always be checked if the SimObject contains any WASM.

 

Having selected an aircraft, you can then used the **spawn toolbar** to spawn it and position it:

    alt="The Spawn Options For The Window" >}}

 

-   {{< button "Spawn" />}}: Click this button to spawn the SimObject at the given position.

 

-   **Lock Position**: When this is checked, the current spawn position is "locked", such that moving the developer camera will not change the spawn position.

 

-   **Display Position Debug**: When this is checked, a debug sphere will be shown to indicate where the SimObject(s) will be spawned.

        alt="The Spawn Sphere Marking Where An Object Will Spawn" >}}
    
    Note that this position is always placed on the ground, and can only be moved by ensuring the Lock Position option is *unchecked* and moving the developer camera.

 

-   **Translation** / **Rotation**: When you select a spawned SimObject, you can select one of these options to show the translation/rotation gizmo, which allows you to change the position and orientation of the object in the world.

 

Finally the window shows a list of the SimObjects that have been spawned in the world. You can select each one in the list and it will be highlighted in the simulation with a wire-frame box (you can also click on the objects in the simulation to select them).

All objects will have the same three options:

 

-   {{< image-icon src="images/2_DevMode/menus/tools/simobject_spawner/icon_edit.png" alt="Edit SimObject Icon">}} **Edit In SimObject Editor** - This button will open the SimObject in [The SimObject Editor](../../../editors/simobject-editor/the-simobject-editor/), if the object can be edited (ie: the package is loaded in the project editor).

 

-   {{< image-icon src="images/2_DevMode/menus/tools/simobject_spawner/icon_view.png" alt="View SimObject Icon">}} **Center Camera on Object** - Clicking this will pan the camera to the SimObject (requires the [Developer Camera](../../camera/#dev_cam) to be enabled)

 

-   {{< image-icon src="images/2_DevMode/menus/tools/simobject_spawner/icon_delete.png" alt="Delete SimObject Icon">}} **Delete Sim** **Object** - Clicking this button will delete the SimObject from the world. Note that you can delete all spawned SimObjects using the {{< button "Remove All" />}} button at the bottom of the window.

 

Certain SimObjects will show an additional option:

 

-   **Play Animation** - Selecting this will list any animations that are available for playing, letting you view the SimObject animated in different ways.
