A set of custom attributes for UdonSharp to automate usually time consuming references and repetitive tasks.
- Auto-set Singleton references
- Auto-set usually tedious references on UdonSharpBehaviours
- Run code any time a build is requested
In your Unity project, go to Window > Package Manager then click the top left +, click on Add package from git URL and paste this link:
https://github.com/LiveDimensions/VRRefAssist.git?path=/Packages/com.livedimensions.vrrefassist
Or download the latest package from the latest release
Requirements:
- UdonSharp
- Git (to install through Package Manager)
Some code is still WIP, but most of the desired functionality is already working.
One big note would be that at this moment there is no 'customization' options for which automations are run per scene this means that your console might get spammed a little bit if you change scenes and don't have the same RunOnBuild scene setup. Also, by default all field and method automations will execute when building but also when entering play mode, if you wish to change this go to VR RefAssist > Settings
[Singleton]
This class attribute marks an UdonSharpBehaviour as a singleton and means that any other classes with serialized references to the singleton class will be automatically set (if it is present in the scene).
[Singleton]
public class MySingleton : UdonSharpBehaviour
{
}
public class TestClass : UdonSharpBehaviour
{
[SerializedField] private MySingleton mySingleton; //This reference will be automatically set by VR RefAssist
}[RunOnBuild]
This attribute is supported on both static and instance methods! These methods will be run whenever a VRChat build is requested.
There is also an optional executionOrder parameter, values higher than 1000 will execute after field automation. Default value is 0 (Runs before any field automation).
public class BuildDate : UdonSharpBehaviour
{
//VR RefAssist field attributes are set before any RunOnBuild methods are executed.
[SerializedField, GetComponent] public TextMeshPro buildDateText;
//UpdateBuildText will be run when a build is requested and will set the TextMeshPro text to the build date.
#if UNITY_EDITOR && !COMPILER_UDONSHARP
[RunOnBuild]
private void UpdateBuildText()
{
buildDateText.text = "This world was built " + DateTime.Now;
}
#endif
}The following field attributes implement different functionality to automatically set any references on serialized fields, this means that public or private fields with [SerializeField] will work.
All fields have an optional bool parameter dontOverride which means that if a field already has a value, it will not attempt to set it again, useful if you want to override a specific field.
NOTE: Even though the names of the methods are not plural, they all support array references and will populate accordingly.
[GetComponent]
Will run GetComponent(<Field Type>) on it's UdonSharpBehaviour to set that reference.
[SerializedField, GetComponent] private Renderer myRenderer;[GetComponentInChildren]
Will run GetComponentInChildren(<Field Type>) on it's UdonSharpBehaviour to set that reference.
[SerializedField, GetComponentInChildren] private Renderer myRenderer;[GetComponentInParent]
Will run GetComponentInParent(<Field Type>) on it's UdonSharpBehaviour to set that reference.
[SerializedField, GetComponentInParent] private Renderer myRenderer;[GetComponentInDirectParent]
Will run transform.parent.GetComponent(<Field Type>) on it's UdonSharpBehaviour to set that reference. This is one of the few attributes that does not directly translate into a Unity method, but it is still useful in some cases.
[SerializedField, GetComponentInDirectParent] private Renderer myRenderer;[FindObjectOfType]
Will run FindObjectOfType(<Field Type>) on it's UdonSharpBehaviour to set that reference. Optionally, you can specify if you want to include disabled GameObjects when running the method. The default value is true for includeDisabled.
[SerializedField, FindObjectOfType] private Renderer myRenderer;
or
[SerializedField, FindObjectOfType(false)] private Renderer myRenderer; //Will not Find disabled Renderers[FindObjectWithTag("Tag")]
Will run GameObject.FindGameObjectWithTag(<Tag>).GetComponent(<Type>) on it's UdonSharpBehaviour to set that reference. If the field is an array, GetComponents is used to get all valid components on a GameObject. Optionally, you can specify if you want to include disabled GameObjects when running the method. By default, it will include disabled GameObjects. This will always include disabled components.
//Will grab all Transforms on each GameObject with the tag "PossibleItemSpawnPoint".
[SerializedField, FindObjectsWithTag("PossibleItemSpawnPoint")] private Transform[] allPossibleItemSpawnPoints;
or
//Will grab all UdonBehaviours on each GameObject with the tag "PuzzleUdons", even if multiple UdonBehaviours are on one object or if the GameObject or UdonBehaviour is disabled.
[SerializedField, FindObjectsWithTag("PuzzleUdons")] private UdonBehaviour[] allPuzzleUdons;
or
//The same as above, but will exclude disabled GameObjects.
[SerializedField, FindObjectsWithTag("PuzzleUdons", false)] private UdonBehaviour[] allPuzzleUdons;[Find("Search")]
Will run Find("Search").GetComponent(<Field Type>) on it's UdonSharpBehaviour to set that reference. This is one of the few attributes that does not directly translates into a Unity method as it runs GetComponent after using Find.
NOTE: Find does not currently support arrays.
[SerializedField, Find("My Renderer")] private Renderer myRenderer;[FindInChildren("Search")]
Will run transform.Find("Search").GetComponent(<Field Type>) on it's UdonSharpBehaviour to set that reference. This is one of the few attributes that does not directly translates into a Unity method as it runs GetComponent after using transform.Find.
NOTE: FindInChildren does not currently support arrays.
[SerializedField, Find("My Renderer")] private Renderer myRenderer;These methods are to be used in editor scripting only. These were implemented because as of Unity 2019.4.31f1 (Current VRChat version) Unitys' FindObjectOfType method does not include disabled GameObjects.

FullSetDirty(Object obj)
Simply runs
EditorUtility.SetDirty(obj);
if (PrefabUtility.IsPartOfAnyPrefab(obj))
{
PrefabUtility.RecordPrefabInstancePropertyModifications(obj);
}
