Serializing Dictionary with Vector3 keys

Questions & Answers
1

hello everyone that finds this question. i need help with saving some data for my game. i need to serialize and store a dictionairy with a vector3 as key. exept unity cant do this for some stupid reason. please help me.

This is the data i want to store:

[System.Serializable]
public class WorldData
{
	public string worldname;
	public int smoothing;
	public int noisetype;
	public float zoom;
	public int octaves;
	public int chunkrenderdistance;
	public int chunksize;

	public Dictionary<Vector3, WorldGenerator.TerrainChunk> WorldDataDictionairy = new 
    Dictionary<Vector3, WorldGenerator.TerrainChunk>();
}

This is the function i nuse to save this data:

    //worldgenerator -> worlddata -> file
    public void SaveWorld()
    {
        var worldgenerator = 
        GameObject.FindObjectOfType<WorldGenerator> 
        ().GetComponent<WorldGenerator>();

        WorldData worlddata = new WorldData();

        worlddata.worldname = worldgenerator.worldname;
        worlddata.chunksize = worldgenerator.chunksize;
        worlddata.chunkrenderdistance = 
        worldgenerator.chunkrenderdistance;
        worlddata.octaves = worldgenerator.octaves;
        worlddata.zoom = worldgenerator.zoom;
        worlddata.noisetype = worldgenerator.noisetype;
        worlddata.smoothing = worldgenerator.smoothing;
        worlddata.WorldDataDictionairy = 
        worldgenerator.currentWorldChunksGenerated;

        BinaryFormatter bf = new BinaryFormatter();
        FileStream file = File.Create(Application.persistentDataPath + "/" + 
        worlddata.worldname + ".world");
        bf.Serialize(file, worlddata);
        file.Close();
    }

this is the function i use to load this data:

    //file -> worlddata -> worldgenerator
    public void LoadWorld()
    {
        var worldgenerator = 
        GameObject.FindObjectOfType<WorldGenerator> 
        ().GetComponent<WorldGenerator>();

        WorldData worlddata = new WorldData();

        BinaryFormatter bf = new BinaryFormatter();
        if(System.IO.File.Exists(Application.persistentDataPath + "/" + 
        DropDownLabel.text + ".world"))
        {
            FileStream file = File.OpenRead(Application.persistentDataPath + 
            "/" + DropDownLabel.text + ".world");
            if(file != null)
            {
                worlddata = (WorldData)bf.Deserialize(file);
                file.Close();
            }
        }


        worldgenerator.worldname = worlddata.worldname;
        worldgenerator.chunksize = worlddata.chunksize;
        worldgenerator.chunkrenderdistance = 
        worlddata.chunkrenderdistance;
        worldgenerator.octaves = worlddata.octaves;
        worldgenerator.zoom = worlddata.zoom;
        worldgenerator.noisetype = worlddata.noisetype;
        worldgenerator.smoothing = worlddata.smoothing;
        worldgenerator.currentWorldChunksGenerated = 
        worlddata.WorldDataDictionairy;
    }

You need to save the information inside the dictionary individually (FALSE). However, your WorldTerrain data might also give you problems. Anyways… something like this:

    foreach(Vector3 key in MyData.Keys)
    {
        //do stuff with the data... 

    }

Is your world procedural? If it is I think it would be way simpler to use Random.Seed and save JUST the random seed. Then when you load the game you just load t hat key, send it to your generator, and then rebuild the world from that.
