Building my game removes all the object spawns

[NaishTech]

Hi when I build my game all the objects under "Gaia Game Object Spawns" which is a child of "Gaia Tools" is not included.

Works fine when playing in the editor.

What am I doing wrong?

Thanks

I will look into this and try to replicate this.

Thanks, I'm using Gaia (3.2.3-c5, Unity 2021.3.2f1)

Pretty much the default configuration (Desktop) with my own custom Biome.

Building windows 64 bit.

So one thing that is interesting is why the Gaia Game Object Spawns are under the Gaia Tools. 
Typically they should be under the Terrain. Which the parent object should be Gaia Terrains. 
Was this moved for any reason? 

It wouldn't show up under Gaia Tools due to the tag being Editor Only.

Hey thanks for the reply.

Sorry I should have mentioned that I did change the spawn target for each of my spawners.

I did this because I have a custom nav mesh agent that treats the terrain (and everything under it) as navigable. If trees are a child of terrain, well you see the problem.

So I figured if, under Spawn Rules, for each rule, if I set Spawner Target Mode to "Single Transform" and set the transform to be a parent GameObject in the root of the scene, then all the objects would spawn there instead.

But when I do that, Gaia seems to delete (or move) the root GameObject and put it under "Gaia Game Object Spawns" instead (which is a child of "Gaia Tools").

Hope this makes sense.

I have been able to replicate this I will send it to the team!

For those interested in a work around, I have created the following script that will intervene in builds and scene openings to unparent and reparent the object spawns respectively.

 

using UnityEditor;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;
using UnityEditor.SceneManagement;
using UnityEngine;
using UnityEngine.SceneManagement;

[InitializeOnLoad]
public class GaiaObjectVisibility : IPreprocessBuildWithReport
{
    public int callbackOrder => 0;

    static GaiaObjectVisibility()
    {
        if (!EditorApplication.isCompiling)
        {
            EditorSceneManager.sceneOpened += EditorSceneManager_sceneOpened;
        }
    }

    private static void EditorSceneManager_sceneOpened(Scene scene, OpenSceneMode mode)
    {
        if (BuildPipeline.isBuildingPlayer) { return; }

        GameObject objectSpawns = GameObject.Find("Gaia Game Object Spawns");

        if (objectSpawns == null) { return; }

        if (objectSpawns.transform.parent != null) { return; }

        objectSpawns.transform.parent = GameObject.Find("Gaia Tools").transform;

        EditorSceneManager.SaveScene(scene);
    }

    public void OnPreprocessBuild(BuildReport report)
    {

        EditorSceneManager.sceneOpened += EditorSceneManager_preProcessSceneOpened;

        UnparentGaiaObjectSpawns();
    }

    public static void EditorSceneManager_preProcessSceneOpened(Scene scene, OpenSceneMode mode)
    {
        UnparentGaiaObjectSpawns();
    }

    public static void UnparentGaiaObjectSpawns()
    {

        GameObject objectSpawns = GameObject.Find("Gaia Game Object Spawns");

        if (objectSpawns == null) { return; }

        objectSpawns.transform.parent = null;

        Scene scene = SceneManager.GetActiveScene();
        EditorSceneManager.SaveScene(scene);

    }


}

Note: that ^ needs to be put in the Editor folder.

Hi @NaishTech,

thanks for posting your solution to this issue! We reviewed the core cause of the objects disappearing, namely:

This was a bug in Gaia where it would clean up previous spawns before spawning again, and deleting the custom transform in that turn. This has been fixed in the latest Gaia update, it should now leave that transform in peace and spawn the objects underneath.
