Title: Caterham Super Seven JPE
Post by: Zapper on March 23, 2021, 03:56:35 PM
Hello you all

A new car is being projected to join STUNTS, this time a track oriented car to a track oriented game.
The very special "Caterham Super Seven Jonathan Palmer Evolution" from 1992 (an evolution over "HPC" version from 1990).

For now, base information, performance and modeling of the showroom shape is on it's final touches:

I hope to complete it in a few days or weeks.

Hi,

Caterham Super Seven JPE has just being released. (already updated to v1.1)
Download here:    CaterhamSuperSevenJPE_v1.1.zip (http://forum.stunts.hu/index.php?action=dlattach;topic=3720.0;attach=7284)

While gathering all data from this car I had to make some compromise choices on colour schemes and dashboard layout, mainly because there is no oficial brochure and also because since this is a special limited version, where aproximatly 50 were made in which then "suffered" from customer personalization afterwards (http://www.thecaterhamregister.net/jpe.htm).

The performance figures were also trickie, because some exemplars have even more tweaked engine (+250HP) and a gearbox with 6 (short track oriented) ratios rather than other 5 gear "more standard" option.

But here it is, the car that in the time it came out, broke the 0-100-0MPH record when released in 1992 (relegating Ferrari F40).

Note: Careful with this feather weight, its prone to "flying carptets" and "fast landings" ;)

The steering wheel is just a composition of "lines" (but not possible on car0 since there were no much more vertices left) ;)

Nice work!  There is a lot of detail in the 3D model.  As you mentioned, it's unfortunate that you can't change the colour of the needles, as white on yellow is a bit hard to see.  Even so, it's a great car! :)
Title: Re: Caterham Super Seven JPE
Post by: Cas on April 09, 2021, 08:52:14 AM
Really beautiful choice of a car. And yes, Stunts limitations impact car development a lot. I wish I could say I'm almost ready with the engine, but nothing further from the truth.

Post by: dreadnaut on October 19, 2021, 12:03:01 AM
Oooh, this is a fun car! Haven't encountered any magic, but its handling is impressive, it feels so light :)

The white needle is a pain though. Do you think you could make the meter disc a bit darker, or make the green bar longer so the needle is visible against it?
Title: Re: Caterham Super Seven JPE
Post by: Zapper on October 19, 2021, 03:11:01 AM
Hi dreadnaut,

that tachometer has that "green line" in order to show the best power range of the engine like shown on this real example:

(https://www.motorlegend.com/images-voiture/med/caterham-super-seven-jpe-42339.jpg)

I can try to make a slightly darker yellow background of it.
Title: Re: Caterham Super Seven JPE
Post by: alanrotoi on October 19, 2021, 03:19:13 AM
I'll try it. Zapper is synonym of high quality custom cars.
Title: Re: Caterham Super Seven JPE
Post by: Zapper on October 19, 2021, 03:19:37 PM
Hi to everyone, after dreadnaut's suggestion here is a test with a less "lime yellow" color on all dial's background:

(test on left, original v1.1 dash on right)

What do you think about it?

The STDA file is attached if you want to try it out.
Title: Re: Caterham Super Seven JPE
Post by: KyLiE on October 19, 2021, 06:30:27 PM
What do you think about it?

It's a little easier to see the needles, but the different shade of yellow doesn't look as nice.  If it was me, I would take some artistic liberties due to the limitations of Stunts and change the colour scheme of the instruments entirely.

Although the natural customization applied in such car as the Lotus/Caterham Seven/Super 7 and all over the years by their owners/assemblers, every Caterham Super 7 in this "JPE" limited edition from 1992 that I found in the internet has that lime yellow color background, which it's also specific of this special version.
So I tried to replicate as much as possible (and as Stunts allows) on this car that matches Stunts era.
Title: Re: Caterham Super Seven JPE
Post by: Ryoma on October 19, 2021, 07:09:04 PM
I am agree with zapper and think that we can let it as is.
Title: Re: Caterham Super Seven JPE
Post by: alanrotoi on October 19, 2021, 07:43:44 PM
I like the cars when are the most close to the real car as possible but if it makes a difficulty of play maybe we should consider an artistic liberties. Also the needle in real car is dark so it's not a big deal if the background is darker because in stunts can't change.

PS: Zapper you have a private message ;D

Lime green is definitely more visible!
Title: Re: Caterham Super Seven JPE
Post by: Daniel3D on October 20, 2021, 08:03:53 AM
I've been thinking about it a bit. And the lime green looks good. quite close to the picture posted earlier.

I don't know if the contrast is good enough for competition though.

Can you try a version that's more like hill green?
With a darker green for the green line at the end of the gage.

Don't know if that will look good.. but I think green is better visible than yellow.

Post by: Ryoma on October 20, 2021, 08:15:00 AM
Sincerely as a car maker, I am not agree with you, guys. Every car has issue in the real life and in Stunts. It was the reason why automotive is so passionnate...

My opinion is : Zapper choose the color and we deal with. It will be a new challenge .

I like this car with the original color and I deal with it. If you are not happy as I said every time, "just do it".

Cas and other people made some wonderful tools to modify easily this.

Zapper raised the issue of the color himself so I'm just trying to help to make a great car even better.
I love the look of the lime green version.
Title: Re: Caterham Super Seven JPE
Post by: KyLiE on October 20, 2021, 09:22:18 AM
Zapper, I know that the lime yellow instruments are unique to the JPE edition and that you were trying to recreate it in Stunts as accurately as possible.  I don't mind the original colour scheme, but I admit that the needles are a little difficult to see.  My suggestion was based on the idea that if you're going to change the colour scheme to improve visibility, then simply use the most contrasting colours that also look appealing.  Otherwise, leave it as is in the name of accuracy.

In saying that, in the attached photo, the instruments look quite close to lime green anyway.

Post by: Cas on October 21, 2021, 07:49:19 AM
One of the ideas Daniel3D gave me that I'm still pending to work on is a method for easily changing the needle colour. For what I've been looking at, it shouldn't be hard. I would change a little piece of the game's code that maybe won't even require recompilation (could be just a patch in the binary file) and that would result in one of the currently useless parameters in the CAR*.RES file becoming the needle colour. If there is interest, I can work on this.

Cas, you are finding the lights here!
I had lost some hope (and time on testing like Ryoma did and described on http://forum.stunts.hu/index.php?topic=3810.0 (http://forum.stunts.hu/index.php?topic=3810.0)) on getting a customized needle colour for some time...
Title: Re: Caterham Super Seven JPE
Post by: Cas on October 22, 2021, 08:38:21 AM
Yeah!  I had posted there before. I'll make another post in that thread to push it up and to add some insight
Title: Re: Caterham Super Seven JPE
Post by: Zapper on November 04, 2021, 02:13:40 AM
Cas, with the recent "great" news from the "Color changing of the needle" post (http://forum.stunts.hu/index.php?topic=3810.msg82262#msg82262) I could finally get a black colored needles, maintaining the "original" lime yellow backgroud color!

So I edit the Caterham's RES file parameter 0D4h (one of the stated "Unknown parameter" in Stunts wiki page (http://wiki.stunts.hu/index.php?title=Car_parameters#Unknown_parameters)) from value "10h" to "00h" and using Stunts 1.1 mod 1.0 (http://forum.stunts.hu/index.php?action=dlattach;topic=3810.0;attach=8587)

Here are the results:
(http://forum.stunts.hu/index.php?action=dlattach;topic=3720.0;attach=8606;image)

I've also attached a preliminary release of the of "Caterham Super Seven JPE v1.1m" specifically for this mod.

Title: Re: Caterham Super Seven JPE
Post by: Daniel3D on November 04, 2021, 06:06:44 AM
The beauty of CAS solution is that for the old version of the game it doesn't change. So you don't have to make a special edition for the mod. Only an update.
It was Ryoma his post that made me look at the code and find the variable. It was CAS that saw the modification potential then.
But it was the Super 7 that made us look for ways to actually do it. CAS did all the programming and I could compile and test, and we just planned a moment to both be awake to do this together.
CAS started at around 8PM (my time zone) I posted our first partial success at 10PM. It was done at midnight. 14 loops of changing, compiling, testing and analysing.  8)

Post by: Cas on November 05, 2021, 01:52:08 AM
Yes!  I'm glad it worked well and it's great to see it in action on custom cars :D

After we achieved this with Daniel3D, I started trying a few options to make the needles separately configurable, but when I passed those to Daniƫl, it didn't seem to work well. I now have made a another, less intrusive version of that and we have to test it. Hopefully, it'll work well. If it does, it'll be compatible with the previous version of the patch, so no need to change the cars a second time.
Title: Re: Caterham Super Seven JPE
Post by: Zapper on November 05, 2021, 04:07:15 PM
The solution implemented by you, Cas and Daniel3D (and everyone involved) on this update "mod 1.0" seams to be simple and have low risk (or no risk at all), like all the best solutions! ;)
Congratulations for your excellent work!
 
Regarding the possibility to get a different needle color I think that it is a bit unusual in real cars, making this possible for me is not so useful as make a possibility to use a digital tachometer like it is actually possible on the speedometer. (sorry for another mod suggestion ;) it would be great to have it on KITT dashboard  ;D)
Title: Re: Caterham Super Seven JPE
Post by: Daniel3D on November 05, 2021, 05:15:15 PM
Some cars have a red tachometer and a white speedometer. And the solution is almost as noninvasive as the first.
It uses bites that are standard 16(White) and 00(black) for speed and tacho respectively.
Basically, if the second byte is 00, then both needles are the colour of the first byte. If the second byte is non-zero, then the speed-o-meter is the colour of the first byte and the tach-o-meter is the colour of the second byte.
What it means is that colour 00(black) is only available for the tach-o-meter if the speed-o-meter colour is also zero. All other colours can be configured separately.
Title: Re: Caterham Super Seven JPE
Post by: Daniel3D on November 05, 2021, 05:17:28 PM
Making a digital tachometer is more intrusive. But should be possible.
Title: Re: Caterham Super Seven JPE
Post by: Cas on November 06, 2021, 02:34:06 AM
Well, yes, now it works! :)  If we didn't do it, the high byte of Red #5 was not used for anything, so this kind of had to be done  ;D

About the digital tach-o-meter, yes, like Daniel3D says, that's more complex and more likely to destabilise the code, but I have thought of it and had mentioned it before. I think that, with some practice, it can be done. Because the code is already there and the information necessary uses the same fields, there's no reason to make it impossible.

Design: 10/10 (Zapper's quality)
Handling: 6/10 (way too fast in corners compared to its top speed, something is strange with shifting... I can't define the problem yet...)
Adventure: 4/10 (I find it rather boring to drive)
