Sounds good, I didn't thought about that. Nice trick, thanks!

You must still be using texture2d / texture function in the end to get index - you can use something like this (example is bicubic filtering) - but you'd need to adapt your shader to add palette lookup (i'm guessing you have that in another texture where you store palette clut and just replace ...

May i suggest an graphics option to use bilinear filtering?


Sure I will add filtering, but it is'nt trivial as one might expect since all graphics is stored in paletted format (single channel unsigned byte) and color gets generated in shaders - so it's not enough just to generate mipmaps and ...

Added live demo: https://codenamecpp.github.io/carnage3d ... _wasm.html
It works on webassembly now

One thing needing to be done is that you model each wheel on the car, so maybe next step is to figure out where tyres should be placed relative to center of body. also, does box2d support off-center mass for body?


The first thing which i've tried is was adding "true" wheels as separate rigid ...

does box2d have any kind of support for top down vehicles? can it get velocity at point on body and apply force on a point?


Yep, disabling gravity force along Y axis gives "top down" mode.
What I am implemented at this point is: each vehicle is single rigid body with dimensions in meters (1 map ...

JernejL , Thanks for reply!

I'm using box2d as physics engine, it is 2d only so I have to fake third dimension - though this is almost no problem. I have decided to try this approach instead of using true 3d physics engine because of simplicity.

I played around with gtacars tool a bit, but it ...

If anyone knows how vehicles physics works in gta1, please share that information.

I've got this message recently https://i.gyazo.com/a0dcd0c7b5f7d3e6d99 ... 9ae1ba.jpg

Are you intending physics as similar to original or just an reimplementation? gta1 ran 2 physicsal models (dummy car drivers) and live cars, player car always used live cars more exact model, and police also use that under some conditions. dummy car drivers use the live model only when they ...

It's been awhile since any significant progress, but project is still alive. Recent update - - implemented weapons and explosions.

Looks very awesome.

Btw, why are pedestrians (and player) are thrown out of car when it explodes? Is this a kinda limitation of the peds state machine - it cannot be in both 'dead' and 'sitting-in-car' states simultaneously?

Thanks, JernejL !
Pedestrians and cars traffic are on todo list of current milestone (Tier1). It is one of many thing to implement for the next test build.

Current progress:

Formats that's one thing, but I mean that gta2 game is more complex in implementation and requires far more time and effort then I can put into...

Thanks, JernejL!
It would be really great if you share that info! I would add it to project repository if you don't mind :)

I'm afraid that GTA2 is too much for me to handle - even both GTA1 and GTA2 has similarities - but it much more complex task to mix them into one. Maybe some day I'll get to ...

Now it open source on github: https://github.com/codenamecpp/carnage3d

Thanks!
Here little demonstration of how the box2d collision works, exe:
carnage3d_test01.zip

To run this you will need:
1) Microsoft Visual C++ 2015 Redistributable, https://www.microsoft.com/en-us/download/details.aspx?id=52685
2) Full version of GTA1 game for windows
3) Hardware that support ...

Hi!

I've started this project some time ago from scratch, just for fun, and working on it now in my spare time.
Here first progress, nothing special - walking (no physics now), simple collisions with map, debug ui:

My goal is to mimic original game (to ...

Welcome to the forum. Are you just curious or are you creating something? Why did you post in this topic?


Thanks :)
Actually i'm creating my own remake of gta1 entirely from scratch (but it currently on very very early stage) and now collecting some info which i believe might be helpful.
I didn ...
