Memory Addresses (SA)

This article may need to be rewritten. Please help improve this article. The discussion page may contain suggestions.

Note that all offsets thus posted have been confirmed for GTA San Andreas (GTA_SA.EXE) version 1.0. This is not for function addresses, for these look into Function Memory Addresses (SA).

Note: None of the memory addresses below will work for GTA: San Andreas v2.0 or 3.0(steam). All addresses in v2.0 and above have been changed or moved. Thus inaccessible.

AlienX: Seems that the Radio Station ID is just a menu identifier, this does not actually 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

  • 0 = on-foot
  • >0 = in-car
• 0x969084 - First vehicle you got into

Note: To get the next vehicle, so the second one, you need to add +0x4 as many times you want. They are 0 if you haven't entered a first/second/third/etc car yet.

Each vehicle object is 2584 (0xA18) bytes. It starts at 0xC502AA0.

For each vehicle in the pool:

  Add these values, and write the sum into +66
  • 1 = n/a
  • 2 = n/a
  • 4 = bullet-proof
  • 8 = fire-proof

Let's say, the Car Position of this given car starts at 0xC5F5DB4:

• +0 = X Level to the ground
• +4 = Y Level to the ground
• +8 = Z Level to the ground
• +16 = X Where am I looking
• +20 = Y Where am I looking
• +24 = Z Where am I looking
• +32 = Dyn flight data
• +36 = Dyn flight data
• +40 = Dyn flight data
• +48 = CarPosX
• +52 = CarPosY
• +56 = CarPosZ

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:

• +1224

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.

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.)

(UZI-I Tested Player Garage and Pay'n'Spray using Hoodlum Crack EXE with an Blank SCM)

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.

Note: Direction Vectors marked above may be Quaternions.

Restart Locations

Also see: opcodes 016C and 016D / save file block 8
An unmodded game has 7 restart locations for "busted" and 8 for "wasted". The memory structure suggests a limit of 10 for both of these.

• 0xa43268: dword -- number of busted structures
• 0xa4326c: dword -- number of wasted structures
• 0xa43270: float[10] -- town numbers for busted structures (1 LS / 2 Country+SF / 3 Desert+LV)
• 0xa43298: float[10] -- angles for busted structures
• 0xa432c0: float[10] -- town numbers for wasted structures (1 LS / 2 Country+SF / 3 Desert+LV)
• 0xa432e8: float[10] -- angles for wasted structures
• 0xa43310: byte[8] -- unknown -- seems to be always the same: 0A D7 A3 39 00 00 00 00
• 0xa43318: float[3][10] -- x,y,z - respawn coords for wasted structures
• 0xa43390: float[3][10] -- x,y,z - respawn coords for busted structures
• 0xa43408: byte[12] -- unknown; matching 12 unknown bytes of save block 8, 0x01 after Busted structures
• 0xa43414: byte[12] -- unknown; matching 12 unknown bytes of save block 8, 0x0F after Busted structures
• 0xa43420: [end]

Notes:

• Town nos. and angles have the busted structures first but coords have the wasted structures first.
• I'm not sure about the end of this structure, but I couldn't recognize anything from the according save block 8 after 0xa43420.

Misc

0xA4892C - Start of the pool stored the flipped vehicles handles. There are 6 elements in there, with each of them:

• +0 = [dword] Vehicle handle to check if it flipped. Stored by opcode 0190.
• +4 = [dword] Time in ms passed from the moment a vehicle flipped. Used by opcode 018F

00A90850 - Start of the mission cleanup list. This list keeps the handles of any entities created during a mission. When the opcode 00D8 executed (normally it happens at the end of any mission), the game reads this list and destroys everything being stored there. Maximum items on the list is 75. Each item has the following structure:

• +0 = [byte] Entity type:
  • 1 - vehicle
  • 2 - actor
  • 3 - object
  • 4 - particle
  • 5 - group (062F)
  • 7 - AS_origin (061D)
  • 8 - action_sequence
  • 9 - decision maker
  • 11 - searchlight
  • 13 - txd_dictionary
• +4 = [dword] entity handle (an index in the proper pool)

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, but can be used anyway:

• 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.
