Weird Vehicle Movement

Bug Reports Engine Bugs
#1

I have a tank that is mostly composed of Unions.

Everything is fine unless I weld the seat to the tank and sit, nothing is wrong unless I sit.

We can clearly see that this is caused by the character since when it’s flying, we can see that the center of mass is on character which shouldn’t have been the case.

The way I control the vehicle is I just add acceleration to the velocity.

Tank.EnginePart.Velocity = Tank.EnginePart.Velocity + Acceleration

There are no body objects in the tank.

Are you using a vehicle seat?

Have you tried to forcefully weld the character to a part (not a seat) then try to move?

#3

Velocity is ugleh. Try a BodyVelocity or a BodyThrust.

Vehicle seat or a normal seat doesn’t change anything. I tried them both. I’ll try your second suggestion.

They do not change the result.

Second didn’t work. Same result.

Just figured that you don’t necessarily have to have your character welded to the tank to get the same effect.

Another effect is this:

When the tank went flying in abnormal movement 2, were you holding any buttons down?

#7

Nope, even if I did, nothing different would happen. I’ve got 8 point rays checking if the wheels are touching the floor so that they can move, if so, to what percentage.

#8

To be honest, a few people tried changing the velocity of a part before, and it didn’t work out so well. I’m inclined to believe that changing velocity simply doesn’t work for vehicles.

#9

The first video shows that it can be done very nicely. The rest is just weird.

Try going here and using a car.
If it flings and jumps around, that means it’s a weird problem with your computer, otherwise it’s something else.

That place is inactive but I’m pretty sure that it isn’t a problem about my computer since the first video worked just fine.

Velocity-based vehicles are outside of my knowledge because I chose a less-difficult method that I could get farther with faster.
