PhysX Vehicle Demo

[crxdx88]

this game looks somewhat like forza motersports <:0

[thedmd86]

@crxdx88 Which release? : )

[crazynitroguy123]

silverstone

[12345samaniegos]

gta 4 drive is more reallistic

[thedmd86]

@12345samaniegos Yes, it is.

[vajuras25]

Wow this demo is actually quite nice. Feels pretty convincing too me. This is a great effort and has very nice potential

[thedmd86]

@vajuras25 Thanks! I give my best (at that time).

[FBSKlub]

very nice!

[kidadam1234]

Wtf Good debug =Good Game

[PhysixGames]

You can't steal my production name =O [As long as you don't name your stuff Physix and stuff it's okay]

[MrSqurk]

@PhysixGames PhysX is a physics engine not the name of his "game". I am sure you don't have it trademarked either so he would be free to call it Physix if he wanted.

[MakubexIsVik]

Cool debug console man!

[thedmd86]

@MakubexIsVik thanks!

[thedmd86]

You need to look for the SDK for Mac OS X. Browse nVidia site for that.

I'm using Unity3D and PhysiX is already integrated. Therefore I'm not in position to help you much.

[dagr8master]

how do I include physX in an Xcode project?

[fcxendan]

You have signs besides the road. The car stucks while passing under those speed signs. Needs fixing. But nice effort. Congratulations.

[thedmd86]

@fcxendan That's true. Thanks.

[RaYk1LL3r]

anybody noticed he wrote rear toruqe? l0l.

[beary443]

u need to fix the steering its 2 fast

[thedmd86]

@beary443 Yes, it is. Workaaround to this issue is to use pad (I'm using XBox 360 controller).

[beary443]

u need ti fux the steering its 2 fast

[yksnimus]

this is physx directly or accessed trough unreal engine? i have no idea how unreal engine works

[thedmd86]

@yksnimus PhysX directly, Unity3D does not have any relation to Unreal Engine.

[yksnimus]

@thedmd86 ROFL, my bad, I read it distracted

[supermansamuel]

At the start I felt like having a Fosters :D

[MechWarrior324]

I miss the days when racing games had car engines that sounded like this. lol

[psychobobek]

you suck at drivin :P'

[henriquegomesHD31]

Can you post the script or make a tutorial?

[thedmd86]

@henriquegomesHD31 I do not have such plans not time to do that. Sorry.

[henriquegomesHD31]

@thedmd86 Oh, i see. Thank you.

[thedmd86]

It's equivalent of --:--:---. Mean no lap time was done. This is developer stuff.

[riflemanxx]

left bottom corner... lap: 0, best lap: 99:59:999, last lap: 99:59:999 i!WTF!i

[FinshFlash]

the map looks like STCC XP

[imalwayswatchingu00]

NICE

[superjermi]

Physx??

[thedmd86]

@superjermi Right.

[pufixas]

@superjermi

um... yeah... Whats wrong with that?

[JTFLTV]

@superjermi Its the nvidia physics software within Unity 3d.

[thedmd86]

@PainlessTragedy Not really, they have more than 600 car models, I have one without ABS. : )

[lllllsp1d3rlllll]

ssj3mohan ur so funny acting like u know what ur talking about like u know game engines or somthing u noobs need to learn ur place and sit down and learn somthing the engine is great as u say PhysX u spelled it wrong.sound like u have just heard of what it is and play games all day cous its all u have to do the game is great the engine is great and easy to use the only flaw is it has a memorey leak do to bad dll's,ocx files

[ssj3mohan]

@lllllsp1d3rlllll ..Dude ,do you have the MoH 2010 ? i do and i dont understand why the single player have the PhysX , (we cant put that thing off ,like Mafia 2) and the multiplayer dont. A lot of user are saying again the ATI dont know how to make the Drivers ,but i have a GT240 ,and tested with my HD5870 ,and rungs pretty well. So on multiplers 80 to 110 FPS ,of singleplayer 20 to 50. The graphic inst better than Multipleys (with no PhysX acceleration) So what do you think about this?

[h0lyh4ck3r]

@ssj3mohan No he has a point if DMM (Digital Molecular Matter) can take the triangles out of models then render those triangles as separate objects and make them fall apart realistically without any help of PhysX then I say well done to LucasArts since TFU does not use PhysX instead it uses Havok which is the basic underlying physics engine with Euphoria which is Bio-Mechanical animation/physics system and then they use DMM. No PhysX in their at all and it's one of the most realistic physics.

[PEPPING4hardstyle]

Woah, nice use of PhysX! pretty impressive.

[thedmd86]

@PEPPING4hardstyle Thanks!

[lllllsp1d3rlllll]

that is very awsome job very realistic besides one thing the damper of the car and abs dont seem to be realistic the car dousnt slid in a corner like a should but i know uv put alot of work into what u have and admire ur for that as close to perfect as any one is going to get havent seen any one get as close to a realistic racing game as urs is.

[thedmd86]

@lllllsp1d3rlllll Thanks for positive!

I have bad news, there is not ABS implemented. :)

I know this car has a flaws, but still, it is nice to have one.

[ssj3mohan]

@lllllsp1d3rlllll You never played a simulation car game ,arent you ? Like GTR2 ,Rfactor ,and GT5. That´s why you dump asshole ,when buy a real car ,crash yourself on the road.

[EXdriver97]

Ok. Good Job :)

[EXdriver97]

Lang. C++? What compilator? Very good work ;)

[thedmd86]

@EXdriver97 Unity3D was used. Code was made using their JavaScript like language.

[KeehanProductions]

TUTORIAL PLEASE!!! :D

[thedmd86]

@KeehanProductions I don't have one. : )

[Carlocap11]

@KeehanProductions just download the file in unity 3d the car tutorial

[thedmd86]

You can play it for free. Link is in movie description.

Source code is not available at the moment. If something change in that matter I will put proper message on YouTube.

[TheDutchGamers]

is it possibble to get the game for free?

[linuxrobotdude]

If thats a comma in your speed indication you are travelling at 1/2 light speed. Thats a big track you got there.

[thedmd86]

@linuxrobotdude Unity scripts are executed using Mono -> number to string conversion is use current locale by default. Since in Poland comma separate integer and fractional part of the number there is nothing odd in the indication.

[linuxrobotdude]

@thedmd86 Hehe, sorry. Didn't think about that.

[thedmd86]

@linuxrobotdude OK. ; )

[Jestek100]

That was really great. It was smooth. Loved it, how do you get the car sound to loop like that, and make the pitch higher as the speed increases. Please help!

I could never figure that out.

[thedmd86]

@Jestek100 There are many samples on the net. This is one of those. It is not great but it is good enough.

Unity allow to modify pitch of the sound and this is the way how it is done.

[Jestek100]

@thedmd86  Thanks for the tip. Just downloaded Unity. Thanks for taking the time to get back to me. It Means alot. Ones again, Great job, I subscribed.

[ssj3mohan]

Not even close of GTR2 ......ahahah PhysX ahahahahh. Nvidia keep working on it, This is like the AMD/ATI says ,its only for sell more GPUs. Belive or not i got 1 GT240 only for PhycX .. And now i have ATI+Nvidia. 1 HD5870 + GT240 ... Big boost when we have PhycX in the game. Like the Batman. But the true is: the CPU can handle all physX .The CPU inst fast like GPU ,but the GPU can get 400FPS and a Good CPu can get 50-80 FPS.But the Cpu can Handle it.

[thedmd86]

@ssj3mohan Nice. I don't take benefit from GPU while using PhysX. I don't need it in fact. My CPU is able to handle all calculations well, mostly because I don't use complicated or very complicated scenes.

PhysX was not the choice. It is in the package with Unity (in fact Unity relies on it).

I know my vehicle don't behave well. It is far from my expectations, but it is much uh better than previous attempts to create vehicle.

[ssj3mohan]

@thedmd86 Plz dude ,i just was criticizing the PhysX engine ,and not your game . You are trying to make the best game as possible ,but this PhysX engine (now with Nvidia) only works to sell more Nvidia´s Gpus. ( check on the Net about the PhysX with X87) you will understand what i am talking about. Do you saw the new Medal of Honor on single player? That shit was with physx on ,and the graphics wasnt better than multiplayer without PhysX. So where is the benifit of PhysX engine?

[thedmd86]

@ssj3mohan Yeah, that's true. Unity make me use this library implicitly. I know about horrible performance on CPU, but I really don't care. In game above there is not that much physics at all.

I do not like PhysX either, but at the moment it have strong support from nVidia and they are pushing developers to use it. Take look at Newton Game Dynamics, is it under development but let you do all the stuff that you cannot do with PhysX. Custom joints, advanced material systems, really advanced.

[ssj3mohan]

@thedmd86 And as you should know,you was forced to use the PhysX even without a dedicate GPU. But there arent any game with a Great physc with PHYSX engine. like gtr2. And as you should to know. the NFS shit patch 1.0 was terrible to ATI GPUs ,all becouse some part of CPU process was optimized to GPU. My real point is ,you was showing a car game with PhysX ,and i dont like what i saw. For now ,the physX still not giving us anything. Even GTR2 is alot better the any physX games.

[thedmd86]

@ssj3mohan Sim games have usually dedicated physics engines, so developers are able to control everything to the ground without waiting for external support.

You can make nice arcade game with current PE, simulations is just different story.

[ssj3mohan]

@thedmd86 Cool you relly understood what i said. The Sim games have a dedicade Physics,but the PhysX of Nvidia ,is terrible ,and a simple core of CPU on the SIM games is enouth to make a great engine,or better saying a great SIM. I love the reality ,but where is it ? Not in batman or Mafia 2. That´s my point. And when someone say ts just to sell more GPU ,is a little hard to say that´s not true.

[thedmd86]

@ssj3mohan PhysX serve for visual effect enhancements, not for reality. Look at the basis, this is impulse based engine and use vague physics pseudo laws. Don't expect more.

[linuxrobotdude]

@ssj3mohan PhysX isn't a graphics renderer. It a physics engine. You can put whatever graphics in whatever detail you want on top of it.

[lllllsp1d3rlllll]

@ssj3mohan

ur a stupid dick his game isnt gtr u cant compare a game made by a company vs one made by a indavidual

[ssj3mohan]

@lllllsp1d3rlllll >no you are a stupid dick your asshole....you should understand ,the PhysX engine ,is to make the Physyc easier to delovepers with a real physical. I dont car if is make of by a indavidual person. The point is the PhysX ( PhysX engine) and this is a shit. I dont saw the lasted videos of him. And i am criticizing the PhysX Engine .and not his work. So be quiet man .

[ssj3mohan]

@lllllsp1d3rlllll No you are a stupid asshole. That guy was showing the stupid PhysX Engine on his game ,and was awfull . I am criticizing the PhysX engine ,Not the game itself. But on real ? The game dont have a Physcs better than NFS ,that is a ARCADE game ,even with PhysX ,that means ,the PhysX engine should make the game easy to creat a great game..So i know what is a real game with almost perfect physc. So before you talk to me go to lear more about the Physc.

[11Mantvis]

Wow the game is so AWESOME!

[thedmd86]

@11Mantvis Nice to hear that.

[yusolaifdfer]

hey please answer my question..

from where can i get car model and track.

and is unity 3d is free

and is this ur game is open source.. fast..

[thedmd86]

@yusolaifdfer First of all, there is no hurry.

If you dig on Internet you will find tons of models of vehicles and tracks.

Unity is free, you can download everything from their home page.

Finally, no. This is not open source project, but there is possibility that above demo will be somewhere around soon.

[coolio9651]

i figured out how to do a donut

!

[coolio9651]

wat do u mean waht does the web link thingy say i cant seem to find it

[thedmd86]

@coolio9651 You're right. Link was in description of Silverstone lap.

Check now. I updated movie description.

[coolio9651]

@thedmd86 thanks i love you!!!!!!!!!!!!!!!!!! i love the game!!!!! 1000000000000000000000000/10

[coolio9651]

can i play the game?

[thedmd86]

@coolio9651 Yes. Link to web player is available in description of the movie.

[ortzinator]

What is WheelShape?

[thedmd86]

@ortzinator NxWheelShape is a single driven wheel suspension model provided by PhysX. It is used to implement WheelCollider in Unity.

[AX53B60]

Really nice! Is there any weight transfering, suspensions and things like that? That would be really awesome :D

From where is the s13 model?

[thedmd86]

@AX53B60 Yes, there are.

Nissan model is from Google Warehouse. Track is from user tack of GTR game.

[thedmd86]

Yes, I had seen this thread. In fact I contribute this project.

[somavision]

Youtube soes not allow me to post the URL of the link here, but do a search for

New Unity Car Tutorial / GTA4 Vehicle Replica Project

You will find it.

[somavision]

Hey dmd86, have you seen this thread in the unity forums?

Maybe you should contact the author of this thread about entering this physx sim?

[konrad12xpl]

so awesome !

[thedmd86]

@konrad12xpl thanks

[somavision]

This is a great looking demo. It appears that the car handles much differently (read: better) from the recent official Extreme Car tutorial that Unity has released.

If you have looked at thier demo, can you comment on how your setup variables differ from the setup that they have built? i asume that you have avoided the wheel collider that unity provides and used raycasting instead.

[thedmd86]

@somavision Thanks. Behavior of car is dynamic because I don't stick to constant values. Maybe I should look at this new tutorial. I haven't seen it yet.

In my demo most of the vehicle properties are dynamically changed during driving. That's give me more control over physics. I also use build in wheel colliders, because they can be tunned well.

[somavision]

@thedmd86 There is a car sim project going on in te Unity forums now. Check it out. Youtube soes not allow me to post the URL of the link here, but do a search for

New Unity Car Tutorial / GTA4 Vehicle Replica Project

You will find it.

[DanEvPro]

The graphics of this demo are the same as a good ps2 game... very nice!

[thedmd86]

Thanks.

[hillarysucksass92]

like this would sell on ps3. no offense its just not that far in yet.

[thedmd86]

I don't get it. First sentence is quite magic for me.

I agree, this is not even a basis for real game.

[PivotMasterLoLeR]

can u sell this on ps3?

[thedmd86]

I'm afraid I cannot. This is just a simple demo, nothing more.

[PKreviewsnvideos]

DUDE this is awesome all you need are some more cars and tracks and you have a game :)

PS:did you make the models(car and track) or did you download them

[thedmd86]

As written in description: all assets are downloaded from Internet, edited to match game requirements and are used as placeholders. It is ok as long as game is freeware. Enjoy it. : )

[PKreviewsnvideos]

@thedmd86 ok but where did you download the car from?and is itfree?

[thedmd86]

3D Warehouse - Google SketchUp repository. Try it.

[ALC96]

great job. did you know you can get a lot of money? i sold my modded counterstrike around my neighbourhood and got at least fifty bucks :)

but you my friend, you made a game by yourself. try adding a multiplayer or something, and then sell it away.... :)))

[thedmd86]

I will think about that. ; )

[MAniAcMC1]

COOL!!!

[digimonworld123]

how did u make your trees

[thedmd86]

Those trees are billboards. They are made by the author of this Silverstone track.

[digimonworld123]

@thedmd86 k thanks

[kptinblk]

can u show us a tutorial on the scripting and stuff for that

[thedmd86]

All my scripting (in Unity) is based on their Wiki, my own ideas and quite simple vehicle model. Also PhysX documentation is handy.

[kptinblk]

@thedmd86 to tell the truth im really new to unity how did u learn all this cuz all i can do is ummm...

pretty much everything except giving controlls and stuff

[AlexanderLMEY]

how did you make everything? The car, i only make sirkles, how do you draw the car and stuff. PLZ anwser. It awsome what you have done.

[thedmd86]

I had used Unity3D Engine. Check it out. It is available for free now.

[badbii]

nice work :)

[tahirmehdi]

What about motor? Did you create it, or unity3d provides it?

[thedmd86]

What did you mean by 'motor'? Vehicle engine? I model one by myself.

Unity3D do not provide any vehicle engine model.

[tahirmehdi]

Yep, vehicle engine. I got it, thank you for reply ^_^

Good job :)

[RIVMASTAR]

Did you make the car and add the physics in unity or did you add them in PhysX?

[thedmd86]

Unity3D is using PhysX for rigid bodies and collistions.

[thedmd86]

I'm currently using Unity3D.

[Xarro92]

Ok i will try, and another question, what graphic engine are you using?

[Xarro92]

Hey, can you send me a PM, with your WheelShape Desc and the Tirefunction Desc? Please!

[thedmd86]

Well, I think I can, but which one? Since wheel setup is changed dynamically there is no gold values for which your cas will behave like real one.

[Xarro92]

please try to send something that can help me

[thedmd86]

Be specific. I will not do your homework and/or task in job. Show me where exacly your problem is and then I will try to help you.

Have you tried to setup your vehicle? What king of problems did you have?

[Xarro92]

I need the car a little drift, with my setup the car physics its to arcade... the friction seems infinte

[thedmd86]

So try to decrease stiffness. Not by one or two but for example one hundred. Keep changins until you got wanted behaviour. Keep in mind: to obrain reasonable behaviour you need to change this dynamically, in my case thiose values are dependent from speed.

[1amStudios]

wow, that looks very cool! I understand the amount of time you must have spent to tune physx to perform like that! Were there any particular parameters which really helped the realism? How about implementing some lateral slippage, especially on the rear wheels? :) Also playable demo?

[thedmd86]

The key to acheve reasonable behaviour of physx wheel is to dynamically modify stiffness. Of course it is not good enought but for now is sufficient.

Playable demo will be available soon, probably together with next movie.

I have a question. Had you done NFS1 remake, or that was somebody else?

[lanzer4]

Very nice,

[thedmd86]

Thanks.

[thedmd86]

It is great that someone else enjoy this demo except me. : )

This demo was created to learn details about engine. Release unfortunately is not planed. Propably game may be available by web (like casual games). Please keep in mind that this was not created for web deployment.

There is much more to do than adding AI and more assets. Mostly under the hood stuff. You can track progress of deveoping this demo, because I put there a new video after adding another major features.

[WessValor]

Damn, this brings me back to the Dreamcast and PS2/Xbox years.

All you gotta do is add AI, a few more maps, and an entertaining announcer and I'm playing games again 8D.... That graphics aren't a problem to me.

When are you releasing this (if you are)? I wanna make custom city maps for this, badly >_>...
