[Solved] Linking a Model with code?

yaRnMcDonuts · May 15, 2019, 9:19pm

I am having trouble finding out how I can link a model with the assetManager. I know how to link a model in the SDK (and the differences between adding and linking), but now I am trying to link a model at run time for use in a level editor tool I’m working on, and I cannot figure out what code I need to use.

Context:
I need to add a radio box option for a model spawning tool, so that the user can decide if they want the models linked, batched, or added. I also need to know how to determine if a model is linked when initially loaded, so that I can flag it as a linked asset in the interface, and ensure it is saved as a link when the scene is re-saved.

Thanks

You can use AssetLinkNode

github.com

jMonkeyEngine/jmonkeyengine/blob/c4d2de1656680cf92a1ea1d16af4c57ee1275783/jme3-core/src/main/java/com/jme3/scene/AssetLinkNode.java#L56


import java.util.logging.Level;
import java.util.logging.Logger;
/**
 * The AssetLinkNode does not store its children when exported to file.
 * Instead, you can add a list of AssetKeys that will be loaded and attached
 * when the AssetLinkNode is restored.
 *
 * @author normenhansen
 */
public class AssetLinkNode extends Node {
    protected ArrayList<ModelKey> assetLoaderKeys = new ArrayList<ModelKey>();
    protected Map<ModelKey, Spatial> assetChildren = new HashMap<ModelKey, Spatial>();
    public AssetLinkNode() {
    }
    public AssetLinkNode(ModelKey key) {
        this(key.getName(), key);
    }

and here is the test:

Thanks, that’s exactly what I was looking for

And if you wonder how to do X or Y (especially how to find out if it’s AssetLinked or something), you can also always easily look into the SDK Code, which you can almost copy 1:1 for most cases
