Midtown Madness 3: Unofficial PC porting project

[SuperSecret]

Just using the original game assets is a copyright infringement, so I don't think the sites in question would accept it. On the other hand, it could be shared on torrent sites without problems.

Anyway, I managed to avoid the loss of control of the cars at high speeds using a mix of increased tire friction and angular drag applied according to the speed (Probably MM3 used something similar, since in the car tuning files there are some parameters related to "AntiSpin"). Now the next step is add proper tuning and sound to the cars.

Good work so far! Im looking forward to it.

[Kunal2045]

Sounds good.

OK, I discovered the real secret of MM3 cars stability: in MM3 the gravity is 3 times the Earth's gravity (Earth's gravity is 9.81 m/s^2, in MM3 it is roughly 30 m/s^2), I increased the gravity in Unity and now the cars behave much more like in MM3, without artificial aids such as anti-roll and variable tire friction (angular drag is still needed, but probably MM3 used it as well), and also the jumps are the same as in MM3 (just an example: in MM3 you need to go at about 200 km/h to jump over the Seine, this can happen only if the gravity is roughly 30 m/s^2)

Awesome !

Quick question, is the game really playable now in Paris already ? Or I misunderstood ?

Thanks !

[SuperSecret]

As of Build 3 you can pick a car and roam around any of the two cities, just no sound, objects or traffic yet.

Feel free to upload a new build to try the updated physics when you can.

[Cariboost]

The city has no texture and everything is black for now

But awesome project !!!

EDIT : somehow I reextract, changed my resolution, put full screen and it worked !!

Really incredible man, you ported a huge part of MM3 in less than a month ??

Question, my lengh of vision is really short ! is there a way to improve this ?

[sajmon14]

Very nice work

Question, my lengh of vision is really short ! is there a way to improve this ?

If you mean the draw distance, it depends on what you mean by "really short", if it's like this: then it's as intended (I set a short draw distance for better performance EDIT: the draw distance in the screenshot is more or less the same as in the original MM3, if not greater, but I can add a slider in the settings menu later), if it's shorter, then it's a bug.

Anyway, Build 4 is available, you can download it here. (it requires the Data folder from Build 1) Here's the changelog:

• Loading screen modified, now it's rendered with proper size and aspect ratio (the selected car's loading screen now is also used)
  The car color/skin selected in the menu now is also loaded ingame
  Car tuning and stability improved - now cars behave much more like in the original MM3 (even if still not in the same way)
  Added a small temporary km/h speedometer in the upper left corner of the screen
  Car cameras fixed
  Ingame camera FOV changed from 60

Looks good, remember to add fog into it, that helps the draw distance thing, and having culling helps performance. You don't even need to do it mm3's way, there are other ways to do it which are probably simpler and faster to implement.

Also, after playing, I noticed this:



The textures need mipmaps. And also, round that km/h speed!

Mathf.Round(variable);

That'll do it!

[SuperSecret]

The artifacts are caused by antialiasing, mipmaps are already implemented, but I had to cap them in the shaders (Unity wants all the mipmaps down to 1x1, while in MM3 they are provided only to a certain level), probably the bug is related to that. The speedometer is only temporary, I will add the proper GUI speedometer later. (both analog and digital, and both km/h and mph)

[Diatosta]

Are cars in MM3 able to climb stairs? Because in this build they can't :/
I never played MM3 so I dunno

[SuperSecret]

In the original MM3 they can, this because the collider is not the same as the visual mesh (while I'm using the visual mesh also as mesh collider), I have to decode the actual collider to fix this.

[Diatosta]

Ah I see.
Also, the cars turn quite well when at low speeds, but when at higher speeds they get a lot of understeer. Dunno if it's that way either :/
