Vettle gets #1, it's automatic. Everyone else get's to pick from 2 - 99.

Thank you kind Sir.

Can someone post a reply of a packed server, with as many people as possible (I'd like to see a full server, with every car racing that is possible.) So I can run benchmarks against the same data set.

The problem is speed of the algorithm. One car (C), on one track (T), on one node (N) using one point is one calculation, and that's what we offer with the MCI packets, with the official tracks, as we get node information (C * N). When we don't get node information, we have One car, on one track, times by the number of points on the track (C^N). Because now we have to test for each node within the pth file. Now when your talking about multiple cars, and multiple points the problem is compounded again. You have to check every car against every point. This quickly becomes an expensive operation for just one server, yet alone a few that PRISM could be installed on, effectively becoming multiple cars, on multiple tracks, using all of the nodes. It's a question of speed, what the fastest way to get this done without having the node information for each client.

To this end, I'm designing PRISM to be fast first. It's going thorough a whole redesign for PHP 5.5, and that upgrade with the same code base alone is a 20% - 40% speed improvement without any code changes (Cool, free performance.) Using SPL, on top of that it should be 25% faster then native arrays when writing data, and use 40% of the memory size, but there is hardly any difference in iteration speed. So my last hope is implementation of R* Trees. It would be odd if an SQLite query would be faster then native memory because of the underlying C structure, but who knows! It's worth a shot for speed.

Cargame has been poking and prodding me for literally years now over the LVS plugin. The plugin verifies that each player's vehicle is on the track at all times. It currently only supports official tracks, using Node information within the packet. The next step is to enhance it to use custom pth files. To make sure this is as fast as possible, as we are talking potentially about doing this over 250 times a second, I've been looking up some solutions. The slowest solution in theory should be the standard PHP array. Then comes SPL (Standard PHP Library) Fixed Arrays and R* Tree using SQLite databases. These two are what I'm going to be testing to see what is faster ... let the battle commence!

So, part of the rewrite that I'm doing for PHP 5.5, is the InSim, HTTP and Telnet interfaces are no longer going to be hard coded into the core of PRISM. I want to be able to implement any type of interface that uses sockets, simply by importing it with a configuration file.

This means a few things, for the core devs. Each interface has to promise to provide a checkTraffic() method and a getSelectableSockets() method. It can also implement a maintenance() method if the interface requires it (InSim Did).

The cool part about doing it this way, is that PRISM becomes quite a bit more general purpose and can be suited to interact with many different types of interfaces quite easily and because of the plugin system attached to it, it can cross pollinate the information from one interface (InSim for Example) with another (WebSockets, Telnet, Ect).

There is another thing, that I wanted to discuss. The deprecation of the HTTP module. I'd like to use the built in PHP server as it should in theory make it easier for people to program for ... if we give them some boilerplate WebSocket interface for them to use. Basically, I wanted to replace the HTTP module with a WebSocket module, and fork anything that we did for HTTP and move that into a separate (but equal) project.

Microsoft basically needs to do a "NT2", but actually make it a clean break. They never will, but they need to actually ditch the gigantic heap of legacy and look towards the future.

Well, NT was kinda like the hybrid of OS/2 and Win32. In fact, NT was built to be 32bit from the ground up, they kinda just bolted on Win16 just to keep everything running in the background. "Hey look, you can upgrade to this, and still use your old applications! When you want to move forward, the infrastructure will be there to support you." Some of OS/2 and some of NT came from Steve Jobs, because they licensed some tech from NeXTSTEP.

Quote from dawesdust_12 :

Apple never killed OS 9 in a day, but over the last 10 years they have switched from OS 9 to OS X, and PPC to Intel without much issue for most users.

And OS 9 was kinda killed in a day, because when Apple bought out NeXT, they pretty much knew that they where buying it because they wanted a new OS, and they wanted Steve back and this one company had both.

And Intel to PPC happend in the back room over many, many years because Macs have always been compatible with x86, and PPC, and ARM. iOS is OSX distilled and boiled down, and compiled for ARM chips.

Quote from dawesdust_12 :

The only users who have had issues are ones who rely on 10 year old software for their daily life, which is a bit crazy (and unbelievable) that something wouldn't exist that was better at that point.

Big Corporations are doing that every day, I still still "Patient Care Registration" running DOS emulators! It's INSANE, but that's because they spend money in the wrong areas.

From my understanding of the SMX and PTH files, there are 65536 units in 1 game meter, that's a pretty good level of fidelity already. That is millimeter precision in the game.

Quote from just2fast :

What about if the peripheral vision (outside red area) is simply rendered with a very very low resolution, and inside the red area with normal resolution?

Ok but why? If some can see it, then why throw away information?

Quick notice for everyone. There is an change in PHP 5.5 that breaks some string parsing in the packets module. It's an interesting "gotcha" that you should all be aware of. I noticed this problem in the LVS plugin when parsing the AXI packets the LName was filled with white space at the end. For now you'll want to trim() any string you get from the PRISM packet system until a core patch is applied.

The parsing error that you are listing was fixed in the last patch that I applied to PRISM on github. Now if you use that link again it will give you a zip file with all of the patches that I've applied for this thread in it. So to make it easy, click here and download. After you've downloaded that, you can simply extract it to the C:/modas directory and it will replace what it needs and update all of the files.

As far as the startup procedure text, it should be lowercase only.

Your doing a direct connection, if its on your local machine. I don't know if you have a listen server or dedicated server. It's a listen server if you start the host and can play at the same time. It's a dedicated host, if you have to start the client to connect to your host, but one does not depend on the other. It's the same nomenclature of Half-Life servers. And it does not matter, PRISM works on Mac, Linux, Windows ... just answer the questions based on the type of server you are connecting too in the fashion you are connecting to it.

Thanks for the update T3, good luck and god speed.

Some say rendering too twice the size and then reducing the image by 50% is the best way to do AA.

Yes I know - and I appreciate that - and Scawen's conservatism (is this english ?!?) - very much... there are really more urgent things on the LFS Todo list than a revolution of the graphics engine :-)

One can dream right?

What are the problems?

Quote from Dajmin :

Right after I get a native Mac version

If only, if only. OpenGL seems like a good idea all around at this point. You decouple yourself from Micrsoft's upgrade cycle and you can lunch the game on Linux (SteamOS), Mac OSX, and Windows all at the same time. That in turns brings up your market share, you'll be one of the first true racing games to be cross platform that people really want to play.

Use that link above again and you'll get a working version of PRISM. I just did a quick run through with the patch that I just applied. From there you should click on the PRISM.bat script and it will start PRISM for you and you just have the answer questions to get it up and running.

Quote from cargame.nl :

You shouldn't edit php files, only the ones in the plugins folder. Unless you know exactly what you are doing better leave the core files alone.

Exactly this. You should redownload PRISM and start fresh.

This link includes that fix fr ... o you should use this one.

From there I would follow cargame's advice and extract it to a root directory in your C:/ drive.

Quote from MadCatX :

Really? How does the user write stuff into their "home" directory on Windows? Isn't the Desktop or My Documents folders there?

Yes you can write stuff to your home directory, and any sub-directory but that's not the point. The point is he just made a hard code articulation when he should of done it in the config file. Let's try to keep a good single to noise ratio please gentlemen.

That's because you should not be doing that at all.

Don't edit the code, it gets this information from the configuration file. You need to put that path in there.

Ok, simple fix for that one is ...


Change that line to that and it should work. I've also patched it on github.

You'll also want to fix the error it's reporting by making a log folder for PRISM to use.

What's the error? What environment are you trying to start PRISM in? MAC? Windows? Linux?

Quote from Whiskey :

I've never been on such a situation, and sure nobody wants to, so I can only wish they can recover from this experience without any further loss.

It's never a fun situation. I applaud their work to help out in the emergency shelters setup in the area. When Hurricane Sandy rolled in too NY last year we pretty much lost a few cities over night. 911 was swamped with calls, Long Beach Fire Department, who are all Volunteers were fighting fires with water up to their chests, and they had multiple building on fire from on the same block, and there were even more fires that they could not even get too. Nassau County has a whole did more calls in the 2 weeks following Sandy then we did all of last year combined. Working as a Captain in another department we covered their ALS (Advanced Life Support) for a while because they lost all of their apparatus. It looks to me, much like what is going on in IL right now.

Anyone who is able to walk should be helping really. This is an MCI (Mass Casualty Incident) Any help anyone can give really helps everyone. It helps the emergency responders, who are incredibly overworked in these situations. It helps the people you are helping because they are getting the help they want or need. And it helps you because you have something to do and you don't think about the devastation surrounding you.

Please everyone spare a moment for a thought for Zenware and T3charmy who both happened to be affected by the tornado that went through Illinios recently. For those that don't know they are both contributing programmers for this PRISM project.

The town of Washington, Ill., about 140 miles southwest of Chicago was particularly hard-hit as an EF-4 tornado touched down there. According to the Associated Press, Washington Mayor Gary Manier estimated that between 250 and 500 homes in the town of 16,000 residents were destroyed or seriously damaged Sunday.

zenware sent me a PM last night telling me that he and T3 were still alive and zenware is working in disaster centers and emergency shelters setup around the area.

Or it could be that the settings are only making the buttons local. I'm pretty sure it's a flag in the ISP_ISI packet.

If your running a host that is also the client in the game, you might be tripping over the ISF_LOCAL flag.
