Lightning Talk: Wasmcloud + Bevy ECS: Solution to Woe of Indie Game Developers - Alan, Poon Yong Quan, Shopee

With the rise of independent content creators in social platforms, there is also a growing market for independent software or game creators. Independent game creators should be able to upload game servers as easily as youtubers uploading videos. Very often indie game developers will shutdown their AWS instances, because the losses due to server cost cannot be recuperated. The presentation will demonstrate the maturity of the Wasm ecosystem in providing low cost cloud platforms for game servers.

A

Hello, everybody, my name, is ellen. Welcome to my talk on western cloud with birvi ecs. How this combination could potentially be the solution to solving role of indie game developers.

A

One of the greatest role of creating multiple player game is usually they will deploy in amazon ec2. Usually the container costs money, so amazon also has a cheaper alternative. Using servers, technology called aws lambda.

A

Let's talk about content creation, let's compare with creating a video and uploading versus creating a game and uploading the game for youtube. It's very simple user can just upload a video and usually the platform best, of course, how about creating a game?

A

It's pretty difficult and a gate developer usually bears the cost.

A

Let's talk talk about burvey burvey is a game engine written in rust and is data driven? So it's quite promising.

A

Let's look at how traditionally people write above you have a server code, you wrote you write app new and you add some plugins and you can add plugins like network plugins and then you can add system, and this is the game logic which is shared between the server side and the client side.

A

And finally, you end up with run, and this will run the game.

A

Let's look at using serverless way and using resin cloud. It's also quite similar. You can just write app new, but you can declare it as a static variable and then you can make use of the actors in western cloud to create something called game logic: actor.

A

You can implement functions like start track in the actor and you can just put in the same logic as previously like the adding the system, which is the game logic, but you can run with uh you can't write and off with run, because this will run infinity loop and you cause error all right, so how you can solve the problem. Is you can right tick? You can register a take command, so within this state command you can mutate the bervi ecs world, which is the entity component system, and you can update the app by itself.

A

This does not work because nobody is calling this stick command.

A

So what I can do is to tell the capability provider to start ticking. So here's the piece of code where you can tell the capital provider to ping this actor with a fixed time interval.

A

Next I'll talk about some of the challenges that I face and if you are very zealous about resin, be prepared of what lies ahead.

A

uh You probably have to consider patching cargo torment, some of the crates here and where exam cloud capability provider needed by the game is not official yet so what do I mean?

A

It means that there's no capability provider that actually gives the actor the timestamp he needs to run the game. So you have to consider writing it yourself, and one of the important trick is to use weather cloud host call without acing await.

A

Finally, some of the useful tools out there is razor snake tool.

A

Okay, how it works first resemble establish a lattice connection with the next communication and then what you have is the nest is able to expose the red socket traffic to the birvi and in bervie I wrote nest protocols to handle the websocket complication. Hence a multiplayer game can be established.

A

All right: here's the demo.

A

So what I'm doing now is I'm going to start chat.

A

Okay, so you can see the the the game is running, but what you see here is uh the western cloud, uh creating an actor and it's healthy and it's it's ready to for a player to join the game. Okay, let's start the game.

A

All right, you can see the chicken and I can move left and right, let's create new game and let's run it side by side.

A

Okay, let's run it side by side.

A

Yeah, you can see that uh this motion the chicken uh moves accordingly. Okay, that's all for the demo.

A

Let's go back to the slides.

A

All right, so one of the good thing about wasm is it's flexible and it's extendable not limited to just birvi. You can consider any game engine that supports web assembly.

A

It's also not emitted the western cloud as the host, while you can consider perhaps ews lambda or resin age.

A

All right, some of the potential benefit to the host is you can you can have a new business plan which is pay per traffic rather than the user has to pay fixed time? A fixed amount by subscription?

A

Well reset is a smaller containerization and with smaller containerization you maximize utility game server. Logic is also can be easily uploaded and downloaded.

A

Some of the potential benefits to get developer is well. You can nft the game server right. You can let the user play for free and sell the nft tokens to those people who are interested in the game.

A

You can ipfs the game. Server binary together with the some of the manifest file. Nft holders can be given special privileges.

A

Finally, I'd like to say that it's quite good for this cloud initiative, because it's open source and there's a streamless attachment to the cloud host provider, it's a pretty easy switch between the game. The cloud host provider just need the club host providers to have the same capability provided needed for the game.

A

That's all bye.
