I’m using the latest verison of Unreal (4.9.1), and it appears the Collision Boxes are broken when using with a Wheeled Vehicle. Even with gravity and physics turned off the Collision Box, the functionality doesn’t appear to work. For example, if you place a collision box well above the vehicle (no overlap) the vehicles just flips out of control continuously. Again, it seems the vehicles need a lot of TLC in the near future.
Additionally, I may be using this part wrong, but Event Hit does not seem to be working with Wheeled Vehicles either. Hit Location, Hit Normal, Normal Impuse, Self Moved always report identical numbers between two colliding wheeled vehicles, even when one is stationary.
The Event Hit is still the same issue, but the collision box appears to only being affecting models we import. Do you know why this would be? Again, there is no overlap, so I’m not sure why it would spiral out of control.
For the collision issue could you try turning off “auto-weld”? As for the event hit issue. I will need more information to help narrow it down. Could you provide steps to reproduce this issue on our end?
Looks like Auto Weld did the trick! I could have sworn that I had toggled that off. As for the Event Hit, I’m simply outputting the Hit Location and Hit Impulse to a print string then hitting the cars together. Both cars always provide identical information, no matter which is moving or where it is hit. Given, it may just be my lack of understanding with Event Hits.
I was unable to reproduce this part of the issue on our end. Would it be possible for you to provide a zipped down copy of your project so that I could take a closer look. You can send it in a private message on the forums if needed. You can do so using dropbox or google drive.
Sure thing! I have the project zipped. How should I send it through a private message or share the project from Google Drive? We use Google Drive so that might be easiest to just share a copy of it with you.
The hit location is going to be the same for each vehicle in this case because it is returning the world location. This means that it will return the location of the impact between the two vehicles. I hope that this helps.
