Name calling, using bad words for one another, etc...

It probably doesn't need to be mentioned, but is important to get right from the start.

We can bash on the collision system's though

**/me promises not to put dirty words in the demo level** just joking

but about the little compo, who's gonna test our systems? what are the rules? who will make test levels? who wants to lose from me?

The community, us, everybody. I've got a feeling it's going to be on ongoing battle back and forth. Probably not a one-time event.

Quote: "what are the rules?"


Fight clean and win.

Quote: "who will make test levels?"


I think it would be fair that we each designed some levels to be tested in both systems. That gives us a chance to point out the weaknesses/strengths for both.

Quote: "who wants to lose from me?"


I didn't sign up on the "lose from Mussi" form. I think I saw someone filling it out though. Was it Exeat I saw?

I personally think that wouldn't work that well, what about if TheGameCreators tested our systems and posted the winner in the newsletter so the winner can take it all

Well, I've got news for you. If you become the "winner" over the systems you won't be there for long I'm not gonna take it laying down.

We just updated the DLL recently too.

To make it short, I don't think there can be a solid conclusion as to the "all-time winner" question when we're battling it out. A good example of this is: someone may win the competition then a month later the other person develops a hot new system that whomps last-month's winner into the ground.

If you want an official TGC comparison I'll be fine with that. The question then becomes "how long is their judgement valid?" They might have to re-compare the systems each month

true, but can you make the wheel any rounder? sometimes you can but I don't think that would happen in less than 1 month, maybe if TGC comes with new upgrades which allowes us to do more, maybe we could make it faster but I don't think there would be a great speed difference, however you may be holding some cards back, I know I am .

lol I'm in a whole different league. That isn't to say my system's worse, it's just that I'm not trying to have the best collision system. I'm simply giving something to the community that they can all work on and contribute to and for those that have no idea about collision, can learn from.

I hope to see some great things from you two though, it should be interesting.

you can return two values.
EG: 1273 can be broken into 12 and 73 with some math.
Check out the multiplayer tutorial in the help file that Vice wrote.

it's really one value with a trick applied. Return a memblock, or if in the DLL, use a class... if possible, then convert to memblock. That would theoretically return two values within the same object.

Mine I presume. I said it's not possible to return more then one value, my solution was to use some Checklist commands like has been done in the past. His post was saying you could do it with Math but I think that's a bit far-fetched and unprofessional IMHO.

it depends on speed of dividing the value up vs. using trig, and how complicated the numbers are already. 2 double/float values wouldn't work well.

Professional in this thread means fast, right?

Actually, I'd also like to know if I can get the Normals of the polygon that's been hit, currently I'm having to do 2 runs of the command to grab 2 points of intersection on the same polygon and then mathematically find the gradient of it. Quite cumbersome and even has some errors. Also, how are you going to return more then one value? We had a discussion about this a while ago and I thought maybe the checklist commands would be used?

Sounds great so far, now I can delete about 200 lines out of my OpenSource collision engine as soon as it's released. Thanks."


I quoted this from Exeat from another thread.

I don't know if finishing my .DLL would be any good to me as TGC are creating these new collision commands and stuff. so Exeat, what do you think about this offer:

we're gonna co-operate to make the best free collision system EVA!!

so what do you need me for? well I van give you acces to what you're looking for pre-proccesed polygon normals and my own raycast system which returns poly normals and world positions etc. and some optimizations, ALL CODED IN DBP!!!

so what do you say ?

Woah! The great Mussi offers to join forces! It sounds good to me but I'm kind of in a bind now since that quoted post. I'm not sure if I should put the system on hold until Upgrade 6 where we'll get a much simpler way to do what I've already done or to just continue now, finish it off and then when U6 comes out rewrite it with the updated Intersect Command. I guess it all depends on how long it will take for them to finish U6, if it's months away then hell, we may as well just finish what we've got but at the moment no one seems to know.

On another note, "pre-proccesed polygon normals", wow, I have no idea how you're using that in your system. With the interesect command I can get real world coordinates and then even if I pre-processed the normals I wouldn't know where to begin with matching up which Normals represents the point I just found. Sounds interesting.

yeah it is , I'd like to show you a demo of this intersect command I made so you can see it for yourself , but how do we contact eachother? msn? forum? I can make a hidden forum for the two of us on apollostudio if you want.

oh and I think we should start right away instead of waiting for update6, when that one is done the only thing we would have to do is update our code a bit

Agreed. My MSN is Exeat@Designex.net - It's probably best you make a forum as well though because the huge difference in timezones might mean I'm never on when you are.

@Exeat and Mussi

I think you'll want to take a look at our homepage.

http://www.nuclearglory.com

We're selling the full C++ source of our collision system. This could give you a serious jump-start on your collision project. Furthermore, I can aide in providing tech. support for the code and we would no longer be working against each other.

How's that sound?

Hey nuclearglory, still up for that challange? incase you are, here's something to boost your confidence of wining up (J/K). I managed to create my own intersect command which returns way more data and probably is about 20 times faster than the original intersect command (find it very unbeliefable myself to but it's true ).

hey Mussi if I sent you an e-mail, could you give me a little help with accessing object data in VC++? I'm interested in trying something similar to what you have done, but I'm not sure how I'd access the vertex information in a DLL, without using memblocks.

I know it's possible but I don't think it's been documented yet, as far as I know, NuclearGlory (and I assume Mussi does too) parse the loaded object to the compiler as a memblock and use that info, or something along those lines.

hmmm... that sounds interesting. if either of those 2 would like to elaborate that would be great... I was also thinking about using the (unofficial) v6 vertex commands in conjunction with IanM's C++ interface to get at the vertex data for the objects... might work... If I could write a faster, and more detailed intersect object command on my own, I would be very proud of myself

I'll probably go back to my old code and give it out open source again. I may have a try at creating my own intersect command (only because Mussi had so much luck ) but I'll wait until U6 to see which is faster.

I've been following this topic and have been pretty excited to see that you're all working towards building a great collision system.

At this point, what's the public allowed to know on the progess?

cool, i just found this thread and it looks like you guys are going to end up with one hell of a collision system, i mean so far they all sound amazing but if you help each other then this could be, well, i don't know, i'm lost for words. i've never really thought about collision much, had too much work for school to do so i used some simple matrix get ground height and bsp stuff for collision, (and ng for latest game) so this should be really interesting for me, not to mention useful.

keep up the work guys

The DLL will be delayed, cuz my friend, which was doing the C++ part can't do it anymore due to personal reasons . This means I'll have to do it, I don't have that much experience in coding with c++ but I'm sure I'll be able handle it. hope to be able to show my first function soon, the raycast function
