[Q|SA] Traffic AI Question

[savidge]

Hello, I wanted to know if it's possible to make all land vehicles in San Andreas have the same traffic AI as the police department vehicles. For instance, in places like Mulholland, the vehicles' wheels "hover" off the ground sometimes because it's a hilly road on a slant, whereas if a police vehicle were to drive up the same hilly road, it would have all four wheels on the ground and it would behave the same way as if CJ was driving it himself. If anybody knows how to do this either via SCM editing or via CLEO, it'd be much appreciated. Thanks for reading

Didn't know that the AI behaves differently depending on the area. Well I noticed one change, the cars on highways were driving so f********g fast that one hispanic w***e just pushed me once with her Nebula, I had full health, and I died.

Yeah, that's another thing. I managed to find some script that edits the highway traffic nodes so that they slow down a fair bit, but what also bugs me is that they exit on the outside lane a lot. I've had too many car wrecks to recall because of this

Thanks man, this is just what I was looking for! I don't know what you mean by "problems" but I have only one flaw to point out -- some vehicles try to overtake others at red lights and end up waiting for the red light on the other side of the road. Other than that, this script is brilliant!

i just wanted to randomize AI )) anyway here's a small "lazy update". just ctrl+c ctrl+v all traffic part of CCarCtrl in each struct, i hope this one will fix all issues without crashes. also, if you know some unused addresses in carstruct, u can replace bomb address, what im using as mark

Wow, this is brilliant! Yep, it works fine without any crashing issues as well, you should release this on the Mod Showroom or something, I bet loads of people would want this. Thanks again, feel free to contribute more if you've found something worth mentioning
