GTAMP

Thanks Tezur0 for finding bugs on Residential. I released a new version with bugfixes.

# Version 1.0.1

- The redneck yellow phones don't crash the game anymore.
- The scientist mission "Redneck Attack!" now clear the on_mission flags at the very end of cleanup. This means that if you start another ...

Hi!

After successfully convert the PSX maps to PC, I wondered if I can do that backwards, i.e. converting PC maps from DMA map editor into PSX readable maps. To achieve that goal, I needed to create my own GMP compressor, which was what I did.

...but is there anyway to turn off player display names?


I've found the address 0x5EAD76 in 9.6f or 11.44 which stores the boolean value (1 byte) for displaying names. Here is an example of toggling on/off displaying player names dynamically:



COUNTER show_player_name_add = 6204790
COUNTER ...

I've encountered another problem.
For Industrial map size a lot of objects required summary, approximately 2000-5000.
Tried to add 1000 trashcans with random XY-coords. Game can't start, crashes upon level loading.
Reduced amount of bins to 300, the game lasts 1 min 34 sec, then crashes.
The same ...

News!

- Now it contains the flipped versions of the main districts. Four new versions:
1 - Flipped x coordinates (right is left and vice-versa)
2 - Flipped y coordinates (top is bottom and vice-versa)
3 - Rotated 90° clockwise and flipped x coordinates (northeast is southwest and vice-versa)
4 ...

You managed to disable the rendering optimizations

GTA 2 in 3D is awesome!

Many thanks to the dude, you can’t imagine how I am grateful to you and I am waiting for other areas for a coop with my wife!


Thanks for playing it! I've released downtown coop a long time ago but I didn't continue to make residential coop because I was waiting for feedback, and making coop ...

This could be a problem with traffic lights.

If you change map 90 or 270 degrees, originally horisontal layout made for 4:3 screen ratio will fit closer horisontally, and could cause 2 traffic lights to be seen that were originally not.

Traffic light zones must be at least a screen away ...

News! I've finished a program which changes xyz parameters from gta2 script. It uses python as well. I've annexed on the first post the singleplayer maps rotated. I need to fix Industrial District weird crash though. It crashes after some ~20 seconds of gameplay for a unknown reason, even if I stand ...

The CMAP chunk of PSX gmp files written in C, if anyone is interested:


struct block_info
{
UInt16 left, right, top, bottom, lid;
UInt8 arrows;
UInt8 slope_type;
};

struct partial_block_info
{
UInt16 lid;
UInt8 arrows;
UInt8 slope_type;
};

struct psx_compressed_map
{
UInt16 base [256][256 ...

is there any difference in sty file format for ps2? do those style files not just open in my gta2 style editor?


All chunk headers (their positions in the file and their size) are missing in PSX sty file, but they can be found at another separated file called GAME.OVL. Their size do not include ...

All PSX maps:
Includes all PSX zones and animations.

I know the "blockd" param stores the block indexes of a column in DMAP and CMAP when compressing the map using map editor, but the "blockd" param in PSX gmp files seems to be different. My code now can read correctly CMAPs created by map editor, as well as DMAPs, but I'm struggling to read PSX maps ...

does gta2 map editor not load cmap and dmap?

So.. compressed cmap is basically 256 * 256 16 bit lookup table of columns (called base)
followed by 16 bit nuber of all columns structures
followed by column structures of varying lengths. and then table of blocks
base is lookup into columns and ...

You "stole" my idea valps.

I wanted to do this years ago but got stuck and left it. I guess im lazy.

Im just too busy with working on my Youtube channels.
Need to grow the income and stuff.

No time to code so much.

Compression / decompression is easy in GTA2.
If you use C++ then youre fine ...

Hi!

I'm developing a GMP rotator/flipper. It already rotates/flips:

- Block positions
- Block tile lids
- Block tile sides
- All types of slopes
- Road arrows (green & red) & field arrows (for trains)
- Light coordinates
- Zone coordinates

The source code is here: https://github.com/Valps/gta2 ...

Not just upside down but 90 and 270 anti-clockwise versions as well.

I'm making a program which rotates a gta2 map entirely.

For now I will just drop this here

I managed to restore the original palettes from the binaries using python. Here are the pages:

I will slice them into individual bmp tiles soon.

EDIT: I've finally extracted all PSX tiles individually.

EDIT2: I've embedded all PSX tiles into STY files. They are ready to use in map editor ...

I looked into GTA2.exe, it seems it always calls wasted.wav for dying or something. Its hardcoded.
I attached the screenshot. The nr 1 in red box is the wasted.wav

I havent yet digged so deeply into this, this function is choosing what audio is played:

Do you have the addresses of the functions you have found? Of course, if you want to share them. I can try to reverse them and make 100% match of these functions in C++.
