Figure this is worth a separate post, as it entails a question.
So, I finally knuckled down and learned how to improve AI lines. I have a strangely functional AI Line for
@RMi_wood 's Washington DC Street Circuit that I mentioned above. AI is 4-4.5 seconds quicker than stock in the RSS Lambo, and about ~3.5 seconds quicker in the TT Cup. Everything seems to be working well - I weaved in extra hints and incidents are now quite rare. A good thing, considering this circuit is a complete death trap.
I just have one problem - on first boot, the cars will not start when the lights go out. They'll just sit there at the start-finish line, slowly edging out of their starting box until they roll away slowly a half minute later. If I restart the event once, though - even if it's instant and I don't even see the lights go out - they roll away at lights out perfectly.
Is this a problem with my AI line, or perhaps an issue with the track? I don't see any major segmentation at the start-finish line in the purple fast_lane, as I was sure to overlap. The left and right boundaries are also as far left and right as they can be at the grid - so no cars are outside of the red boundaries at the start. Disabling the AI behavior in CSP does nothing, sadly.
I feel like it's my simple mistake - I'd appreciate someone in the know chiming in to point me in the right direction.
If I can get this start issue squared away, I'd be happy to give this line out for further testing. Cheers.
