Hi !

Context: A real-time 1-on-1 Multiplayer game, imagine Golf.

Player 1 hits, both players see the ball projectile at the same time. So, ball is synced. I'm using Photon, so I'm doing the syncing manually. Player 1 sees the actual motion, and Player 2, as long as both connections are decent, I could sync the ball nicely, and even interpolate x,y and add velocities to smooth out the motion near-perfectly.

Problem: Often, players lag a little too much and it starts to glitch/skip. I want to get rid of lag-based problems completely by showing Player 2 an imitation (a projectile) of what Player 1 has hit.

Although it's a real-time turn-by-turn game, but there could be a couple of seconds delay, which is fine as long as it looks smooth!

Question: How can I re-create the exact same projectile of the Ball on the other end? There are many factors, especially after it lands and rolls on grass (the decrease in velocities, etc.). I assume there is no way to make the ball stop at the exact same position, twice, despite the same initial impulse/location.

I was thinking is there any other way to improvise? e.g. I would do an Object-time scale and see exactly what happens in the future (within just 1 second). But how to re-create that on the other end?

Or any other ideas?

Thanks!

Is that true that there is no way to transfer the host to another peer using the multiplayer plugin if the host disconnect?

Ribis Jase00 Yes. That's right. Unless you're willing to keep a separate PC/device running 24/7 acting as a Host of each Room, essentially creating a Master Server yourself, then it is possible to achieve Among Us style game. But then again.. Considering the connectivity issues, you'll also need a paid dedicated Cloud based server on top of that to let everyone be able to connect.

Too much hassle really, which is why I'd not recommend C3 Multiplayer plugin for such games.

By the way, Photon does allow sending messages to only selected / Targeted people. eleanorjmorel hasn't explored it enough.

Cascade Games

There are multiple. The free one allows 20 players at a time. The next one is $95 for 3 months that allows up to 100 simultaneous players playing. And after that is $95 per month that allows 500+ players at a time.

Note: Imagine having up to 20 players playing SIMULATENOUSLY in your Multiplayer game, not all the time but regularly, every day. What it means is before you'll require upgrading (or paying), you'd already be earning $100+ per month easily. So for a $95 for three months that allows 100 players, you wouldn't even think twice.

Jase00 Yes. Massive difference. My advice: Switch to Photon, Scirra's Multiplayer will drive you crazy sooner or later.

Main differences:

1. Scirra's Multiplayer is simply a Peer-to-Peer connection, where one of the peers is hosting the server. If that "host" leaves, the game basically ends! No more communication possible between peers, whereas, Photon has a Master server which is hosting the room on Cloud (not at any players' end), so if any player leaves, or even all of them leave, they can join back and continue. Game continues.
2. Second main difference: Scirra's Multiplayer has Firewall/NAT connectivity issues. So basically, you'll be reaching out to 50% to 60% of the audience, rest won't be able to connect. (I made a really cool game, and found out, I could not connect myself when I changed my network provider). And many other players complained they cannot connect. Photon connects literally 100% of the time! Very stable and reliable.
3. Third main difference: Photon is far easier to use, set-up, and understand (even as a complete beginner) than C3 Multiplayer. No need to "Sync" objects beforehand. Just "Connect to server" and "Connect to a Room", then start communicating/send messages/data. etc.

The only con of Photon, the Free version allows maximum 20 simultaneous connections (players) to be connected at a time. For more CCUs, there are paid packages.

But ! I'll tell you what, if you're getting 20 players at a time regularly in your game (that has Ads/inApps), that means you're definitely earning enough to cover for the paid package that allows 100+ simultaneous players. So that's also not really a drawback.

AnConstructerBro Among Us style game can easily be made through Photon, but as Sebastien said, I agree, first learn C3 (non-Multiplayer games) thoroughly before jumping into making a Multiplayer game.

I agree with —

What annoys me is that if the Founder is least bothered or motivated to solve a bug, then why/how should we be?

Ashley not knowing a bug was fine, but NOW he knows. — posted a minimal example of a Behaviour clearly NOT working, and Ashley did see that. An expected response from Ashley would have been: "Oh. Yeah, that doesn't seem right at all, Let me forward this to my team, they'll have a look!"

I mean, what would he do to file a Bug Report? Post the exact same thing there? It's already clearly narrowed down! So technically, even Ashley or developer can file a bug report now. But would they?

It's exactly the same nonsense as when you Rate/Review an app/game reporting a problem, no matter how clear you are, and yet you get a copy-pasted response saying: "We're sorry, can you please email our support team to describe your issue.." bla bla.. Oh well, by that time the user has already uninstalled their app/game, and don't give a S. Similarly, if the developers of C3 are not keen on listening here on the Forum, then soon we won't give a S either, especially if we're paying Annually.
