AlienX: Seems that the Radio Station ID is just a menu identifier, this does not acctually change the radio station while in-game!

Another note... The opcode for switching players radio stations does not work in line with the station ID's, i have yet to figure out what station ID's are for the SCM code - Dont try to use the above ID's for the SCM Operation Code, it just wont work

Thanks to AlienX For the station names and ID's

Pedestrians

General

0xB7CD98 - Player pointer, direct offset to the ped pool start (CPed).

Following offsets are Floats, as positions of doors and other car parts that gets detached by damage. We need to recalculate and set their locations if we warp a car from one location to another. Otherwise the car spins uncontrollably:

+1828 Detachables1 Pos X
+1832 Detachables1 Pos Y
+1836 Detachables1 Pos Z
+1872 Detachables2 Pos X
+1876 Detachables2 Pos Y
+1880 Detachables2 Pos Z
+1916 Detachables3 Pos X
+1920 Detachables3 Pos Y
+1924 Detachables3 Pos Z
+1960 Detachables4 Pos X
+1964 Detachables4 Pos Y
+1968 Detachables4 Pos Z

The locations of the detachable objects are different for cars and bikes. This is merely because bike object is actually smaller than the car object. The car object is used for all vehicles (including heli) but the bikes.

Offsets for Detachables:

+1532 BikeDetachPosAdr(0)
+1632 BikeDetachPosAdr(1)
+1676 BikeDetachPosAdr(2)
+1720 BikeDetachPosAdr(3)
+1764 BikeDetachPosAdr(4)

+1828 CarDetachPosAdr(0)
+1872 CarDetachPosAdr(1)
+1916 CarDetachPosAdr(2)
+1960 CarDetachPosAdr(3)

The trailer of the tanker is handled the same way as the vehicles. Its pointer gets set at offset:

+0x4C8

To the car object start. When warping vehicles that has trailer, we need to warp this 'vehicle' as well. The same pointer is used also when you are towing other vehicles as well.

Rockets

The rocket pool contains info on launched rockets (for example, Hydra rockets).

0xC891A8 = Rocket pool start. Each slot has 36 bytes of data. There are 32 elements in the pool.

+0 [DWord] = Rocket type: 16 = None, 19 = Normal, 20 = Heatseeking, 58 = Flare
+4 [DWord] = Pointer to launching vehicle
+8 [DWord] = Pointer to target vehicle (when heatseeking), 0 otherwise
+16 [Byte] = Does rocket exist? 0 = Exploded / does not exist, 1 = Travelling
+20 [Float] = X-axis position
+24 [Float] = Y-axis position
+28 [Float] = Z-axis position

Race Checkpoints

The checkpoints block that are used in the "illegal street racing" mini-games.

0xC7F158 - Checkpoint block start. Each block is 38 bytes, but theres always only two at a time.

+0 [Byte] = Type of checkpoint
+2 [Byte] = RGBA color value
+4 [Float] = X-axis Position
+8 [Float] = Y-axis Position
+12 [Float] = Z-axis Position
+16 to +24 [All Floats] = Rotation Matrix (direction from this checkpoint to the next)
+32 [Float] = Checkpoint radius

Garages and Parking

Note, that the memory location of garages can vary depending on the scm script you use.

There are 50 Garages in the game. Each garage has:-

Position
Details
Usage information
Location in game
Location of door
Width
Depth
Height
Direction it looks
Coordinates of lower left corner
Coordinates of upper right corner,
Usable by the player
Which property (safe house) it belongs
Number of vehicles which can be parked inside
The door state (closed, opening, open and closing)

These are found in the garage object of 212 bytes. The memory locations where the garages start are:

0x96C048 (start of first garage)
+0xD4 (offset for second garage - offset this much again for third garage, again for fourth, etc.)
0x96C120 (start of final garage)

(Tested using non-patched original v1.0 German EXE with English language option selected, and original SCM file.)

Here is the known garage offsets:

0 [Float] X Coord of the Garage Lower Left corner
4 [Float] Y Coord of the Garage Lower Left corner
8 [Float] Z Coord of the Garage Lower Left corner
12 [Float] X Value of direction vector 1
16 [Float] Y Value of direction vector 1
20 [Float] X Value of direction vector 2
24 [Float] Y Value of direction vector 2
28 [Float] Top Z Coord. of the garage
32 [Float] Normalized Width of the garage
36 [Float] Normalized Depth of the garage
40 [Float] Left Border (X) corrdinate
44 [Float] Right Border (X) corrdinate
48 [Float] Front Border (Y) corrdinate
52 [Float] Back Border (Y) corrdinate
77 [Byte] Garage Door State values:
- 0 = Closed
- 1 = Open
- 2 = Opening
- 3 = Closing

The direction vector 3 is completely left out, I think because the garages are always even to the ground. I think that is also why the Z values of the direction vectors are also left-out.

Here are the static Adresses of the Garage Blocks, and to which garage they belong:

0x96C048 Commerce Region, Loading Bay Garage
0x96C120 Unknown Garage
0x96C1F8 Unknown Garage near El Corona

Threads

0xA8B42C pointer to the first active SCM thread

Weather Codes

0xC81318 [Word] = Weather lock (by AlienX)
0xC8131C [Word] = Upcoming weather
0xC81320 [Word] = Current weather

The following values tie up with the sections in data/timecycp.dat. There are several different kinds of weathers (including underwater), and the current weather affects viewing distance, sky colour, fog intensity, and other things like that. The appearance of each weather is time-dependent too.

Weather Values:

0 = EXTRASUNNY_LA
1 = SUNNY_LA
2 = EXTRASUNNY_SMOG_LA
3 = SUNNY_SMOG_LA
4 = CLOUDY_LA
5 = SUNNY_SF
6 = EXTRASUNNY_SF
7 = CLOUDY_SF
8 = RAINY_SF
9 = FOGGY_SF
10 = SUNNY_VEGAS
11 = EXTRASUNNY_VEGAS (heat waves)
12 = CLOUDY_VEGAS
13 = EXTRASUNNY_COUNTRYSIDE
14 = SUNNY_COUNTRYSIDE
15 = CLOUDY_COUNTRYSIDE
16 = RAINY_COUNTRYSIDE
17 = EXTRASUNNY_DESERT
18 = SUNNY_DESERT
19 = SANDSTORM_DESERT
20 = UNDERWATER (greenish, foggy)
21 = EXTRACOLOURS_1 (very dark, gradiented skyline, purple) Used for interiors?
22 = EXTRACOLOURS_2 (very dark, gradiented skyline, green) Used for interiors?

The following are not mentioned in that file, make of them what you will:

23 to 26 = variations of pale orange
27 to 29 = variations of fresh blue
30 to 32 = variations of dark, cloudy, teal
33 = dark, cloudy, brown
34 = blue/purple, regular
35 = dull brown
36 to 38 = bright, foggy, orange
39 = extremely bright
40 to 42 = blue/purple cloudy
43 = dark toxic clouds
44 = black/white sky
45 = black/purple sky

Warning: Setting these values to anything higher will result in things like black screen, flickering, really red, etc.

Dependencies

Car ptr = player ptr when on foot.

[Note: This depends on which address for the pointer is being used, if the car pointer appears to be the same as the player pointer on foot, then you may be using a camera-related target pointer.]

CPed block size = 0x7C4 bytes.
CVehicle block size = 0x0A18 bytes.
