isVehicleOnGround returning false for high vehicles

[guix]

Hello,

I have an small problem because isVehicleOnGround does'nt always work , for example with Dumper or Monster, it's most of the time returning false, only if for example I do a big jump and when landing the suspensions go down, so then it is true for a short time. I believe it's something to do with comparing distance from vehicle's mass center with ground.

What can I do?

What are you trying to do with this function?

I try to add a detection when vehicle is upside down, to make a "autoflip". I think I fixed it by replacing isVehicleOnGround by:

local fGroundZ = getGroundPosition ( fPositionX, fPositionY, fPositionZ )

if fPositionZ - fGroundZ < 3 then // vehicle is close to ground

Works very well but need to test more.

Use rotations?

How are rotations useful in my case?

Please read the first post, or just the topic title. I don't need this, I was just answering to his weird, indiscrete question...

Use

getElementDistanceFromCentreOfMassToBaseOfModel 

[Blaawee]

maybe :

getGroundPosition 

and check this :

Use

getElementDistanceFromCentreOfMassToBaseOfModel 

I have tried with this before but it doesn't work very well (especially when vehicle is upside down )

maybe :

getGroundPosition 

and check this :

It's what I used in 3rd post, It's what I use in my script for now, until I make a proper fix to be very accurate with all vehicle.

You can also check the speed of the z as.

speedx, speedy, speedz = getElementVelocity ( vehicle )

( outputDebugString(speedz) /debugscript 3 )
