Vehicles in UE4 , a constructive debate

Wtf? i readed everything before posting, Zireael07. and i saw people saying that its needed IA Vehicle class (or IA Vehicle controller) then i said i could achieve this without any class or hard coding.

1st. I said AI Cars, (not Cars only), cars possesed by computer with paths and physics, cars by themselves are so easy to achieve in this Engine.

2nd. I have no problems with bumps or things like that, vehicles launch in the air if u hop so much but cause the physics…

3rd. For who needs to know, if ur vehicle launch in the air like crazy, is cause ur root model is not well rotated, so later u will have problems with physics and normals. In Maya change root to -90 0 0, C4d 0 -90 0. That solved me the problems with wheels and jigging, weird moves etc.

I have even a Client Side prediction System (no lag notice when multiplayer driving) and more than 5 vehicles with tires, with no problems.

Could u explain me, Zireael ur problem with vehicles? I could help u.

Bye bye.

I am using the default car, default model, default settings, so it’s not a matter of wrong root. It’s that, the way PhysX works, cars can get launched in the air on small bumps.

and that hasn’t been fixed to these days

I’ve seen a lot of the problems in this thread, but my problem is somewhat different.

The vehicles are rock-solid when it comes to collision. If I collide with another (same setup) vehicle at full-speed, it won’t even budge. It literally just sits there. Maybe, maybe they move a little when hit @ 200 mph.

It’s a simple vehicle setup, weighing about 1500 kg. Any clues?

PS: I might be able to upload a video later showing this behavior.

**EDIT: ** Nevermind, this is a known issue: UE-21990

I know this is an old thread now but I’d really like some vehicle AI to be able use “out the box”, simple things like RVO avoidance, overtaking, not getting stuck etc
