StuntGP - someone? something? (SGPRV)

[martin]

It is rather a accidental way how I get here but anyway, it is nice to see that a community is still active. I'm just wondering how many players here recognize or had played StuntGP from Team17 (Well I'm sure about the one player)? This product came out nearly in the same time, it wasn't as much technologically advanced comparing to Re-Volt, but differed in many other aspects. Personally I preferred SGP over RV and spend many hours playing it back in the old days.

The point: my intention here is simply to put the cars and track into RVGL. For now I have managed to accomplish the most 'dirty' part - reverse engineering and understanding of the significant parts of game models formats. There are finishing steps left in the whole pipeline like: fixing the models and applying the surfaces hierarchy, writing the configurations files, adding pick-ups to the tracks, and so on. For me time is a biggest obstacle , so any help is appreciated if this attempt has any interest worth continuation.







Tool set consists mainly of blender import script (without UI) for model files, textures decompresser and converter with its sources. Current Toolset ^{BTW: why attachments are disabled?}

I'm interested! Me and Marv have both wondered about porting some of this content over, but never quite managed to rip any models. I'm really curious how you figured it out.

The biggest obstacle I see would be the car antennas. @Huki: Any chance we might see a fix for the twitchy antenna tips in the near future?

Looking at the attachment settings, it should work. Maybe there's a mandatory requirement to post at least once before being allowed to upload. Check if it works now?

Woooooooow that's the best xmas present!
A while ago I tried to do the same and failed miserably: https://yethiel.wordpress.com/2017/04/2 ... ructure-1/

It's amazing you managed to figure out how the files work, I'll read through the sources soon, I'm really curious!

That is cool!

We decided to create a channel on the RV Workshop for this, since it can be more convenient when it comes to collaborative projects. If anyone would like to help with the conversion process, please join us!

I didn't knew this game before, but it looks very interesting. Good work, Martin!

Maybe you also know the game Ignition ("Bleifuss Fun" in german), from 1997? I tried to rip the cars from it last year, but I failed. I think also Jigebren tried one day, and he succeeded. But he didn't documented anywhere, how he had done it. And now he is not around anymore...

I think the cars from both Stunt GP and Ignition would fit perfectly in Re-Volt. I love this forklift from your picture!

Looking forward seeing some of the stuff inside RVGL.

I converted all textures and cars and put them in one .blend file so they can be cleaned from the lights and LoD models and exported to PRM
Links are on the Workshop Discord server. Should I make the files available here, too?

The alternate paint jobs are going to be great since RVGL supports them too

Wow what a quick feedback, slow down to avoid missed decisions . Note that some coordinates are screwed because of my attempt to convert a rotation matrix from left to right hand coordinate system (swapping a sign is not enough), it helps to just manually negate a sign in object position and rotation in object mode. Also objects are large scaled, some normalization in code would be beneficial on start if needed.

I'm really curious how you figured it out.

It is a question or a statement ? Maybe this will surprise you or satisfy your curiosity: for sure it is not my first "successful" attempt in such a job so a brief answer might be as usual: experience? 010 Hex Editor has a nice unique and helpful templates feature, I'm using top down approach by trying to cover 100% of the data and then divide it on smaller structured chunks by searching for repeating data. The purpose of information held by the file (this case 3D mesh representation) must be put on front. Experience in low level programming helps to think on what the programmer meant by putting this or that there. Finally the puzzle are solved and meaning of the most structures entries becomes clear. Sometimes you even need to be familiar with reading and debugging pure asm code as particular old games and most of new ones use a assets encryption, program executable is only one tip you have. Another approach is to just ask for source code or its part, rarely successful but sometimes... wait a year for permissions or find out that source is lost somewhere.

Yes, I read it and through this I have discovered that revolt works natively on linux kernels, also wondered why progress somehow stopped year ago, difficulties or thing not worth the effort. If you hit the wall just just wait for the problem to resolve for itself (not always work).

I know about that game but did not play more than a test launch. If I will find some time I may take a look into it, it is a big chance that it is a "two days quest" since game worked even on MS DOS and someone else succeed with analysis.

Wow, this is like a dream. This is amazing. I've had so many visions of other games being done like stunt racer 64, ridge racer 64, rush 2 and so forth but those are mainly n64 titles which i believe are much harder to re-imahine and build into re-vomt. I'm assuming this is pc?

@martin: I've heard of StuntGP, but never played it. It's a really interesting breakthrough...

What's the issue exactly? I suggest opening a thread in bug reports / suggestions.

The model can be replaced just fine, but it constantly rotates at 90° angles (depending on momentum?).

This video is pretty old, but as far as I'm aware it still behaves the same (the pink flag):

Nice work ... deeply it is finished to test it.

[Black-Revolt001]

Are the circuits finalized?

Are the circuits finalized?

Not yet.

Whew lad, i rarely use this account here, but, here we go.

Recently, i called some old Re-Volt players and parameter people / friends to help me get this thing revived again, and, here it is.

This includes the 20+1 cars from Stunt GP (the +1 is the Stunt-Bowl Hawk), all of them have carboxes, parameters, hulls, shadows, pretty graphics and whatnot. They lack currently their flags / antennas (aerial tops) and maybe minor tweaks.

Take note the parameters weren't meant to be a 100% copy of StuntGP (Most of the cars are more of the same there, and when fully-upgraded, they are all equal, there is no difference almost), but rather a "what if they were on Re-Volt". Take note of the CarSpecs.txt to know what to expect more or less of each vehicle.

Enjoy!
