World/Udon Bugs & Feature Requests

Additional Array methods were added in https://docs.vrchat.com/v2021.4.1/docs/vrchat-202114#changes-improvements-and-fixes-1 with the accompanying canny post marked as complete https://feedback.vrchat.com/vrchat-udon-closed-alpha-feedback/p/add-more-array-methods-to-all-array-types but Array.Sort was mysteriously left out. This would be EXTREMELY useful for quickly making a deterministic list of players using GetPlayers()'s VRCPlayerApi array by playerId (and then sorting the VRCPlayerApis by playerID with Array.Sort(keys, items)). Currently in Udon that array is out of order for different clients, and individual playerIds represent their join order, rather than an autofilled sequence from players leaving and joining. It would also be useful for sorting VRCPlayerApis by a world's game score for a scoreboard. Array.Sort is extremely useful because, even though we don't have access to custom data structures or IComparable implementations in Udon, we can still sort things using associated arrays of intrinsic data types. And before you do the same thing that you did with the previous post, please just whitelist everything you can. Not just Array methods. Stringbuilders. Native Unity components like LODGroups. Although a rumor, I heard that ReflectionProbe endpoints weren't included for a YEAR after Udon's release because there was a blacklist for anything with 'reflection' in the name. Please consider going back through the whitelist and enabled anything and everything possible.

Physics simulations in VRChat are limited in realism because creators can't modify most of the variables in physics settings. For example, I'm working on a mini golf map and my golf balls stick to walls at low speeds rather than bouncing off realistically. I've gotten the editor's simulation to look nearly 1:1 with real golf balls by changing the "Bounce Threshold" in the PhysicsManager to 0. However, these changes do not carry over when I'm testing the map in VRChat. I can maybe understand restricting the solver iterations to prevent lag, but even then it should be up to creators to optimize their worlds. If the physics settings can be made changeable it would be very appreciated!

Right now OnInputMethodChanged only get called if well input method changed, but I think I would make sense to have it called once to let the world figure out the user input and switch any logic without having to manually do it with GetLastUsedInputMethod()

In a recent SDK update, the Scene Descriptor doesn't show the Network IDs list, making it quite difficult to manually tweak Network IDs. I believe this is unintentional as the Editor component for the Scene Descriptor still has code to build the inspector for the Network ID list. The problem is with the line propNetworkIDs = serializedObject.FindProperty(nameof(VRCSceneDescriptor.NetworkIDCollection)); because "NetworkIDCollection" is not the name of the serialized property for network IDs. The correct name is "NetworkIDs".

On the Quest platform, when clicking on a pre-filled VRCUrlInputField, the focus is set to the beginning of the URL. This behavior is inconsistent with the PC/PCVR version, where the focus is correctly set to the end of the string, allowing normal and more convenient typing behavior. Video of the issue: https://youtu.be/gSU8lyfVZMc Might be related to: https://feedback.vrchat.com/open-beta/p/1400-wrong-cursor-position-when-clicking-on-pre-filled-url-input-field

This would easily allow nicer looking dropdowns

TMPro.TextMeshPro and TMPro.TextMeshProUGUI both inherit from TMPRro.TMP_Text. Therefore, we can access both as common interface such as TMP_Text.text by using the TMPro.TMP_Text.

If an interactive UI canvas sets its Graphics Raycaster component's "Blocking Objects" to "ThreeD" or "All", users won't be able to interact with it. This is because of a change in Unity 2022.3.22f1.

See the screenshot below. These players can exist like that for up to an hour, if not longer. This causes issues when they are the master and you rely on them to handle important networking logic. They won't be able to send data to others, which can mess stuff up, like Cyan's Object Pool. In my case I rely quiet heavily on it and it renders the world completely unusable in the time the quest player is master and sleeping. Proposed Solution: kick the quest player get their master status revoked after some time add way to transfer master manually in udon

In the current version of VRChat, the bottom left of the screen seems to have a cursor which triggers the Pointer Enter and Pointer Exit events on Event Trigger components. Example video VR: (The pointer seems to be slightly outside of the FOV, so it's a bit difficult visualize) https://www.youtube.com/watch?v=nu8bcsVqj4E For reference, this also happens on desktop but will probably cause less issues. https://www.youtube.com/watch?v=cv1dVWzF_7Q The setup looks like the attached screenshot. This can be quite a problem for creating UIs that are attached to the left hand. I usually disable hand interactions if the hand pointer is over the UI. However, this issue causes that function to trigger whenever the hand is in the wrong position. Edit 16.5.2023: A test world is now available (reset button included) https://vrchat.com/home/world/wrld_0d0bd6a8-9508-44a0-a07c-66f121ad8347
