New game: Top down city


Recommended Posts

I've been working on this for ages, but recently i found some time to resurrect it and get it up to some useable standards. 


My own game.. Top down city! 


Youtube channel with some videos: 



Here's a really basic video that shows internet multiplayer (really basic) 



I hope that this appeals the classics gta community, and hopefully gives you something to chew in the future, because while similar in appearace there's simply no comparing gta1/gta2 engines to this. 

- Full physics engine - meaning all map block shapes behave correctly as you would expect, no strange behaviors of being stuck on partial blocks, engine also has and supports trucks with trailers. 
- No limit on sprite dimensions: delta sets will be probably scrapped in the future, but for now you can have any texture resolution for map tiles, objects, and vehicles, game looks great in high resolution. 
- Graphics: map shadows,sprite shadows, modern particle system.
- Client/server Networking - Not gta tick based sync which limits amout of max players and causes severe lag
- Editors: All editors will be released with the game once it's complete (texture packs, maps, vehicle deltas), if anyone wants to try, i will make a pre-release and can get your hands on some tools, but they are already shown how they work in youtube channel. 
- No real limit or penalty on amout of different vehicle, object, particle types that can be added, even map can be resized (the only limit is in amout of possible map tile textures - 4096 tiles max). 


Still in progress: scripting (integrating a modern javascript scripting engine) and more AI - police forces - once this is done, most of main tasks in engine are complete. 


I hope to have some helps from you guys, i'm welcoming if anyone wishes to join the project - map makers, ideas, story for single player.. i need help to make this happen.
And of course I will need testers, a lot of testing, i hope to make some pre-releases where we could also do a massive online test with more than just a few players. 


I've been doing sa-mp for past 10 years and top down city intermittently, but now that i quit sa-mp i have time to return back to my classical roots  
This is happening, the game will be made complete hopefully this or next year.

You could import gta maps and vehicles if you wanted with a suitable converter, it would be even possible to import multiple maps into one map as top down city supports any size maps without any hard limits

But the goal is to make a standalone game without any gta content with good file formats to have it as much future-proof as possible (high resolution sprites, massively extendable engine). 


But that's just the technical part, the main goal of the project is to have a really fun and competitive multiplayer and a really fast "pipeline" where anyone can very quickly create new maps, weapons and vehicles to buiild a online world.

Progress was good in past few weeks, i've added automatic damage modelling / deformations for vehicle collisions, fixed a dozen behaviors / internal problems in stuff like static map objects. 
I've also upgraded tools, and finally made the vehicle sprite editor not crash randomly, making it pretty stable, map editor still needs more work but is also good enough for now. 
A good new feature is working multiple seats on motorbikes, meaning 2 players can actually sit on motorbike, one driver and one passenger (nothing will not stop anyone making a 20-seats long motorbike). 
AI traffic and police ai had some minor updates and fixes aswell. 
I'm still working tirelessly on network synchronization of particles / bullets which is needed to release a working alpha version of the game, this needs to work first :)
Here's a video of automatic damage modelling in action:

Do you have a discord server? I'd love to follow your work from there. I'm really interested in this.

This is not using any code or assets from gta, so i can sell this game if i chose in any way, is steam banned in thailand? 


Here's a very new video, the game has a lot of object interactivity and i put in a lot of new map objects.

Yes, The GTA Games is banned since GTA 1 to EFLC but except GTA V is only available in Thailand.

Haha! Looks really quite impressive. But, about the screen space, instead of showing behind and in front of your vehicle 50/50, it would surely be more practical to have it like 70/30, so that whatever is coming up in front of you is more visible. You get me? Kudos though anyway!#


**edit: ive just checked your youtube videos and it seems youve kinda done that already. nice one!

I got a update for this! i released a new demo - it is now much more refined, and is much more closer to a proper release: 


Here is a offical 2020 demo: 



Give this a try, and report how the game works and if you find any issues. 


I've been playing this and happy to keep testing. I love the movement of the vehicles. I encountered no major problems on my first little play of it,

other than the cops do not seem to arrest you quick enough when pulling you from a vehicle, resulting in a sort of competition between you and the cop

and getting in and out of the car.


I at one point saw a pedestrian stuck inside the corner of a building around 3/4 layers up just clipping with the walls. other than that this looks smooth,

and feels very much like the original GTA experience. Very well done. I love the idea that you are making this game open to mod too, keeping with the GTA

philosophy that is too. I would consider a more stylized HUD in terms of weapons at the bottom instead of their game models (or close to) being displayed.

I'm sure you're already thinking about that though and this is just because of the test enviroment but overall this is awesome.

One other thing... the lights 'spread' on the police cars could be a little bigger, but also could do with being slightly more transparent.

Hello everyone! 


I can give an update of this finally, i've added lighting and this changes the game atmosphere greatly:

And here are all the changes from january when i last time posted, hopefully this shows that this is a stable and progressing project :)
