QUESTION
I have a component that instantiates a few classes from the Tone.js library (e.g audio players and filters) and defines a few functions acting on these objects, which are used as callbacks in a set of UI-rendered buttons (see relevant code below).
Two of these buttons are supposed to toggle the boolean state is3D
using the useState hook (in the updateSpatial
function) in order to enable/disable one of these buttons. However, this update obviously causes the component to re-render entirely, thus re-instantiating my classes, which prevent the defined functions to work afterwards.
In contrast, I also tried the useRef hook, which allows for is3D
update without re-rendering, but the button's disabled state is not updated as the component does not re-render.
Is there a pattern that fits with this situation? My next attempts include using HOC, Context, or Redux, but I'm not sure this is the most straighforward. Thanks!
...ANSWER
Answered 2021-May-05 at 13:50I see two things wrong with your code. First, everything within the "normal" body of the function will be executed on on every render. Hence, the need for states and hooks. States allow you to keep data between renders, and hooks allow you to do a particular action upon a state change.
Second, useEffect(()=>console.log(hi))
does not have any dependencies, hence it will run on every render.
useEffect(()=>console.log(hi),[])
will execute only on the first render.
useEffect(()=>console.log(hi),[player1])
will execute when player1 changes.
useEffect(()=>console.log(hi),[player1, player2])
will execute when player1 OR player2 change.
Be careful with hooks with dependencies. If you set the state of one of the dependencies within the hook itself, it will create an infinite loop
Here is something closer to what you want:

QUESTION
I am currently building an online game with Photon Networking using Unity and I have a problem with Photon.Realtime.Player.SetCustomProperties() method. I've already googled it but I couldn't find anything like my issue.
About the projectThe matchmaking system is nothing very fancy: I have a first scene to login (without password for now), that will connect to Photon. When OnConnectedToMaster
event is raised I load the lobby scene that will display the rooms. And finally, when OnJoinedRoom
is called I load a 3rd scene for the room itself, it will display the players, set teams, game config, etc.
I've made an extension class both for Player and Room (RoomInfo) classes to make it easier and clean to get/set the Custom Properties.
The issueAs soon as I load the Room scene I want to get a few properties from the Player to display in the Room, like MMR (ranking), for example. So I made the following code:
...ANSWER
Answered 2021-Jan-08 at 07:16tl;dr
- never set
Player.CustomProperties
orRoom.CustomProperties
directly (use them as read-only), instead always useSetCustomProperties
methods. - wait for
OnPlayerPropertiesUpdate
callback before trying to access updated property value you just set.
By default, setting properties for actor or room properties will not take effect on the sender/setter client (actor that sets the properties) immediately when joined to an online room unlike what it used to be in PUN Classic. Now, instead, the sender/setter client (actor that sets the properties) will wait for the server event
PropertiesChanged
to apply/set changes locally. So you need to wait untilOnPlayerPropertiesUpdate
orOnRoomPropertiesUpdate
callbacks are triggered for the local client in order to access them. The new behaviour is due to the introduction of the new room option flagroomOptions.BroadcastPropsChangeToAll
which is set totrue
by default. The reason behind this is that properties can easily go out of synchronization if we set them locally first and then send the request to do so on the server and for other actors in the room. The latter might fail and we may end up with properties of the sender/setter client (actor that sets the properties) different locally from what's on the server or on other clients. If you want to have the old behaviour (set properties locally before sending the request to the server to synchronize them) setroomOptions.BroadcastPropsChangeToAll
tofalse
before creating rooms. But we highly recommend against doing this.

QUESTION
I am trying to achieve uploading an MP4 video to Azure Media services; making it available for streaming via a streaming URL, as well as more importantly and specifically to this question: upload .VTT captions to be shown within the video.
I have worked on integrating the code within this tutorial, more specifically the EncodeAndStreamFiles sample app (described in the document) as a DotNetCore API.
I have managed to retrieve a list of streaming URLs for the Video, and the stream works well (the video is playable).
The next step is uploading a .VTT caption (or subtitle). Unfortunately, I have not found any official documentation from Microsoft regarding this subject. This Stack Overflow question is the only useful information I found. Based on the answers to the question; I am uploading the caption within the same blob container as the video's output asset and referring to it by editing the video's streaming URL (replacing the last part).
So if the video's streaming URL is this:
Then the caption's streaming URL would be:
I am trying to display the video and the caption using the advanced options within this tool. The caption appears within the options, but the actual words don't appear on screen.
I have 2 questions -
Is the uploading of the Caption as part of the blob container, the correct way to upload captions? Or is there a better way (perhaps via the SDK) that I haven't run into yet?
If the answer to 1. is Yes, how should the streaming URL for the caption be generated? Is the example shown above correct?

QUESTION
I am trying to code an HTML5 video player. It will only ever be run locally, never on the web. I'm attempting to use Node and Express. I am new to Node. I have created an HTML player and a Node script, which I have used to get a player running in a Node server. I need to be able to browse video files on the local hard drive and load them into the player as one might do, for example, with VLC. I'm aware that Javascript substitutes a fakepath for security reasons. Is it possible to get a real path using Node/Express, and if so, how is best achieved? I'm stuck on how to use the file input button to get a filename and path for a locally held video, and then to load the video into the HTML5 player using Node/Express.
...ANSWER

Yes. You cannot use a file input to pick a file from your local disk for use with a web server. Not even if the server is running on the same computer.
Is it possible to get a real path using Node/Express, and if so, how is best achieved?
To read the file system with the fs
module and send that data from the server to the browser.
You might also want to look at Electron.js which is designed for building desktop applications using Node.js and an embedded browser. It extends the browser with APIs that allow you to read file paths.
