object list not serializing
i have an editor window that modifies variable of scene gameobject. the variable was List and it was working fine, but then i changed modified the code and i needed it to be List. and now it's not serializing (it's cleared when entering play mode).
//Before
[SerializeField]
public List<GameObject> returnValues;
//After
[SerializeField]
public List<object> returnValues;
You can't serialize object. Make a List of a serializable object type instead e.g. Vector3, int, float, ... check this.
If you want to hold custom classes e.g. MyData make sure you mark the class as Serializable i.e.:
[System.Serializable]
public class MyData {
public int intValue;
public UnityEngine.Object objectValue;
public float floatValue;
public string stringValue;
...
}
[SerializeField]
List<MyData> returnValues;
but i need a list that will hold different values (string, int or GameObject in my case). why object can't be serialized?
Unity won't be able to render object to disk, there's no serialized representation for it.
You can't hold different values there unless all of them are inherit from a common serializable class e.g. UnityEngine.Object, where you can hold Texture2D, GameObject, Component...
Also, worth mentioning polymorphic serialization (not officially supported by Unity yet AFAI$$anonymous$$, but you can make it work)
I've changed the code snippet so that $$anonymous$$yData can hold the values you want to store. You just need to know which type is each $$anonymous$$yData instance to retrieve it property (as SerializedProperty does, for example)
