Improve ai using ai_hints.ini - Full list of variables and explanation?

I've been trying to modify some ai problem points on tracks e.g.
Modern Monza - first chicane - First lap crashes with Ferrari 312T or Lotus 49.

I've read several posts about using ai_hints.ini for the track. Unfortunately, I cannot find a full list of commands and variables, and how to use them. I've mostly just been using trial and error.

HEADERS
[HINT_0]
[DANGER_0]
[BRAKEHINT_0]

Do these have different effects or are they just titles?



START and END
START=0.145
END=0.175

The part of the track where the effects will happen.
The figures can be found by looking at NCP in the Car Physics app.
This app needs to be enabled:
ENABLE_DEV_APPS=1 in assetto_corsa.ini
Steam Library\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini



LEFT and RIGHT
LEFT=0.5
RIGHT=0.5
Do these "narrow" the track e.g. to funnel the cars into a chicane or to stop them crashing into barriers.
Is 0.99 (1.00) the maximum value?



VALUE
VALUE=0.7
70% of normal AI speed?



I would welcome any advice on how they can be used.
Are there any other variables that I've missed?

Thanks for your help.

 

Hello Richard,

two days to go. Then there is an update on AI. I think it makes sense to wait and see then

 

Good idea!
Thanks for your reply.

 

briefly

HINT_x multiply the radius of the corner seen by the AI. Useful when AI is too fast or too slow in a corner.. usually due to compression/decompressions but there could be other reasons such as hairpin with long straight after and where the AI is going in too hot loosing in exit speed.
BRAKEHINT_x changes the AI idea of how hard it can brake in that zone.. again some compression and,especially decompression area might need this
DANGER_x is an hint that kicks in when the AI is engaged and it's informing the AI to take it easy in that section if engaged.. it's used very rarely

 

Great!!!
Thanks for your help.

 

Hi,

thanks for your reply on this post!

Can you point to any further documentation on the ai hints file? Specifically, I´m not sure how to understand the "danger" type - how does it work with the left/right values, and when exactly is this hint-type used/triggered? You mention that the AI needs to be "engaged" for it to be triggered?

I also saw the use of a "Max Speed" hint in another - I assume it´s self explanatory, but made me wonder if there are other types of hints I don´t know about. Is there a full list somewhere?

Working on a better single-player experience for some mod-tracks, and very often need to improve lines and hints


Thanks!
