Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to get rid of vehicle/car sideways sliding/give it the movement limitations of a boat?

Hey all, I am in the process of making a boat from the basic vehicle template ('driving' on the water seemed simple enough), and I can't seem to get my car to stop sliding sideways or just straight up spinning out and coming to a dead stop. I've tried increasing the Lat Stiff value and, while that does seem to reduce sliding long distances, it results in more spin outs where my vehicle comes to a dead stop, and increasing it alot makes the vehicle super jittery. I've tried combinations of 4wd, front drive, rear drive, open and limited slip, nothing seems to make much of a difference. Pretty much, I just want to give my 'car' the limitations of movement a boat would have in the water.

Limitations being:

Absolutely 0 sideways sliding (boats don't sail sideways).

No spinning in place.

Turning would have a hard cap that it couldn't go beyond.

Ideally, would utilize rear wheel steering and no front wheel steering. Not certain how to make that work at all tho. (Maybe reverse the controls and the car mesh?)

So far, using wheel suspension to make my 'boat' bob up and down like it was in the water is a huge step forward (and boost in confidence) and I'd really appreciate some help pinning down these issues if anyone has any ideas they cared to share.

well I cant really help you with 0 sliding sideways but I have done rear wheel steering so I can help with that, all you need to do is open your front wheel blueprint and set the "steer angle" to 0 then open your rear wheel blueprint and set the "steer angle" to 45 or whatever you want and that's it.

hope that helps :)

Hey smokey, thanks for the tip. Did just what I was hoping for. I had totally thought that those numbers were just related to how it would show up on the anim blueprint, not actual steering. :D

Sorry if this answer is late, but if your making a boat, It would probably be better if you made a custom Boat movement. Not vehicle movement it would never look good. Try using Add force nodes and Lerps. Doing with vehicle. You would need to do some serious animation work for the boat's buoyancy effect.
