What is HOFxLap
HOFxLap is a program that dumps details from a GP3/GP3-2000/GP4 hotlap or saved game
to the console.
HOFxLap should currently work with all versions of GP3, GP3-2000 and GP4. If you have
trouble getting it to work with your version then please let me know.
There is no installation procedure. Simply copy all files to anywhere you'd like.
hofxlap.exe [-v<verbosity>] <file> [<file> ...]
Wildcards are allowed to specify multiple files. The default verbosity is 3.
Alternatively, you can use a GUI version of HOFxLap, which shows
the same output in notepad-like frames. Add files by either opening
them or by dragging and dropping them onto the HOFxLapW window.
Currently, HOFxLap outputs the following info:
- GPx version.
- If the file is a hotlap or saved game.
- Track name.
- Opposition level.
- Opposition standard.
- -: all the same.
- /: normal performance levels.
- ~: random.
- Race type.
- Session mode.
- Race percentage and total number of laps (if session mode is a race).
- Number of minutes and number of minutes left (if session mode is qualify or limited practise session).
- Weather type and actual chance of rain (if weather type is custom).
- Car number.
- Driver, team and engine name.
- Car power (BHP). By default, the maximum power is 800 BHP for GP3, 810 BHP for GP3-2000, and 855 BHP for GP4.
- Car weight (kg). By default, the dry weight is 605 kg. For hotlaps, this value is from the start of the hotlap.
- Fuel laps (as shown in the cockpit). For hotlaps, this value is from the start of the hotlap.
- Frame rate.
- Lap time for a hotlap; Fastest lap time for a saved game.
- For a race session in a saved game:
- Number of laps done.
- Race time (at the last cross of the s/f line) and race position.
- Qualify lap time and grid position.
- Fastest lap time and fastlap position.
- Driving aids F1 to F8. The state is shown as it was at the start of the hotlap for a hotlap,
and the moment of saving the game for saved game.
The aids are represented as follows:
This is optionally followed by a * if the aid was toggled
during the hotlap.
- --- if the aid is masked away due to opposition level.
- off if the aid was off at the end of the hotlap.
- on if the aid was on at the end of the hotlap.
- Clutch, brake, throttle, and steering device, mode, and low
- Steering help percentage, max. lock, and reduce with car speed
- Setup: front/rear wing, brake balance, gear ratios, differential, front/rear antiroll-bar, and tyre type.
Wheel settings (order LF, RF, LR, RR): packers, dampers
(fast bump / fast rebound / slow bump / slow rebound), springs, ride height, and plank wear.
Pitstop strategy (race only): number of pitstops, pitstop percentages.
- Extended GPxLap data: checksums, custom track names, pitlane speed limit, and specific data for each lap
like lap times, split times, processor occupancy, toggling of driving help, position, fuel, and tyre wear.
