The carrec.img
file stores a set of R3 files (files with an extension .rrr
). These files contain path information used by the mission script for Grand Theft Auto: San Andreas and Grand Theft Auto IV. The paths are predefined and look unnatural during gameplay because the movement of the vehicle is very rigid. The paths ignore many stuff in the game including gravity and obstacles.
Original San Andreas installation has 426 R3 paths. Maximum number of these paths is 475. GTA IV increases this limit. By default there are 1813 R3 paths. The limit appears to be located somewhere beyond 3000.
GTA IV does not use an image to store the carrec paths. They are located in the directory ...\common\data\paths\.
The RRR file structure
Each RRR file contains no header, only a binary data, being a set of structures of 32 bytes in length each, described separate path points. The data in a path point structure goes as the following:
Offset | Size (in bytes) | Type | Description | Notes |
---|---|---|---|---|
00 | 04 | INT32 | time | Timekey in milliseconds |
04 | 02 | INT16 | velocity in direction X | Divide by 16383.5 to get floating point values |
06 | 02 | INT16 | velocity in direction Y | Divide by 16383.5 to get floating point values |
08 | 02 | INT16 | velocity in direction Z | Divide by 16383.5 to get floating point values |
10 | 01 | INT8 | XYZ.right.x | Divide by 127.0 to get floating point values |
11 | 01 | INT8 | XYZ.right.y | Divide by 127.0 to get floating point values |
12 | 01 | INT8 | XYZ.right.z | Divide by 127.0 to get floating point values |
13 | 01 | INT8 | XYZ.top.x | Divide by 127.0 to get floating point values |
14 | 01 | INT8 | XYZ.top.y | Divide by 127.0 to get floating point values |
15 | 01 | INT8 | XYZ.top.z | Divide by 127.0 to get floating point values |
16 | 01 | INT8 | Steering Angle | Divide by 20.0 to get floating point values |
17 | 01 | INT8 | Gas Pedal Power | Divide by 100.0 to get floating point values |
18 | 01 | INT8 | Brake Pedal Power | Divide by 100.0 to get floating point values |
19 | 01 | INT8 | Handbrake used flag | Bool: 1 = true, 0 = false |
20 | 04 | FLOAT | XYZ.pos.x | Standard float |
24 | 04 | FLOAT | XYZ.pos.y | Standard float |
28 | 04 | FLOAT | XYZ.pos.z | Standard float |
When the vehicle is moving along the path, its XYZ structure is filled with the information from the proper fields of checkpoint data.
Mission Script
San Andreas
You can use the following opcodes to do stuff to your paths.
07C0 - Loads the path
07C1 - Checks if the path has been loaded
0873 - Releases the path from memory
05EB - Assigns a vehicle to the path
0705 - Assigns a vehicle to the path
085E - Assigns a vehicle to a looped path
05EC - Releases the vehicle from a path
05ED - Freezes the vehicle along the path
05EE - Unfreezes the vehicle along the path
06FD - Sets the speed multiplier of the vehicle along the path
0706 - Advances the vehicle along the path
060E - Checks if a path is assigned to the vehicle
If you load a non-existent path to a vehicle, path 1 will be loaded instead.
GTA 4
Use the following native functions:
REQUEST CAR RECORDING
HAS CAR RECORDING BEEN LOADED
REMOVE CAR RECORDING
FIND POSITION IN RECORDING
FIND TIME POSITION IN RECORDING
GET POSITION OF CAR RECORDING AT TIME
GET TOTAL DURATION OF CAR RECORDING
SET RECORDING TO POINT NEAREST TO COORS
SYNCH RECORDING WITH WATER
