What is the best method you have for making LP lines? I generally follow fortine's advice from nrtracks, however I felt like I couldn't make a line like the original papy team. Messing around, I've found that using chassis type 0 for the track I'm trying to edit/create gets me the closest. Here's my general method:
- 1. dial in the grip level. (most of the tracks I'm working on are community made tracks where the grip level is too high. it's really an unfortunate trend and results in bad racing both in terms of ai and player experience.)
- 2. dial in a setup. part of this includes some back and forth with the track_tire_heat, as well as with the grip level. i look at lap times for around the era i'm working in and try to get my fastest lap close to or below the record
- 3. change the chassis type to 0
- 4. make your race lp AS IF you were driving with the normal chassis (e.g. lift where you would normally lift, gas where you normally gas, just like how you had to when you ran good laps with your setup)
- 5. make all other lines as necessary
- 6. change chassis type back to original value
- 7. test with the AI (set ai_accel_modifier, ai_decel_modifier, ai_grip_modifier, ai_drag_modifier, ai_line_modifier to 1). if you don't like the race lp, go back to step 3 and repeat
- 8. once you found a good race lp, start driving with the AI and adjust the values listed in 7 so that they become competitive around 97-100% difficulty. if i find myself having to raise the ai_grip_modifier much above 1.05, i'll leave it be and just race the AI at a higher percent. NOTE there should generally be an inverse relationship between track surface grip and ai_grip_modifier. if both are high (> 1.05), then something's wrong with your race lp and go back to step 3.
- 9. when you get the AI to race well with you for the first 10 or so laps, dial in track_tire_wear, track_tire_wear_loss, and track_tire_wear_exp along with the ai_tire_wear and ai_fuel_use so that they have parity and are appropriate for a full pit cycle. this is where some research/judgement comes in and i'll watch old races on youtube from the era i'm working with to hear how the commenters are describing track conditions, pit windows, etc.
- 10. tweak remaining ai_track values as necessary
