Toboggan Possible?

MileHighGuy · Post by **MileHighGuy** » Sun Oct 19, 2014 4:55 pm

Remember in BF1 when you went prone you could slide down steep hills like you were sledding? Is it possible to recreate that with a vehicle? Or at all?

You know, that actually might be possible with a hover vehicle.

http://www.secretsociety.com/forum/down ... mented.txt

Specifically these parameters:

SetAltitude = 0.5 // Sets the default hover altitude
GravityScale = 4.0 // Sets the mass of the vehicle
LiftSpring = 4.0 // Sets the spring in the hover
LiftDamp = 3.0 // Sets the cushion of the spring on subsequent bounces

Acceleration = 5.25 // Sets the rate of acceleration m/s
Deceleration = 7.0 // Sets the rate of decelleration m/s
Traction = 20.0 // Sets the percent to decrease acceleration rate when starting from zero
ForwardSpeed = 12.0 // Sets the maxspeed m/s
ReverseSpeed = 10.0 // Sets the max reverse speed m/s
StrafeSpeed = 4.5 // Sets the max strafe speed m/s

cool! im making a proof of concept map now.. how do you suggest i change those?

EDIT: Also, how do you suggest i keep the vehicle perpendicular to the ground at all times? I thought it was levelspring and leveldamp but I'm not getting anywhere with those..

Probably lower GravityScale to around 1.0, Traction to 1.0 or 0.0 or something, Deceleration to 0.0, ReverseSpeed to 0.0, and...yeah, that should be a good starting point.

Would probably be best to use BARC or Speederbike ODF and model as template.

WOW.. something cool happened.. I will upload a video soon!

HAHAHAHA! That music is perfect.

Marth8880 · Post by **Marth8880** » Sun Oct 19, 2014 7:33 pm

Sweet! Hmm. You might actually wanna make the GravityScale higher then in that case... Try a value of 20.0 or so.

MileHighGuy · Post by **MileHighGuy** » Sun Oct 19, 2014 7:45 pm

thats better.. although the vehicle sinks in to the ground... and is horizontal the whole way down.. is there any way to make it tilt forward like a normal sled (and not bob back and forth?)

Marth8880 · Post by **Marth8880** » Sun Oct 19, 2014 7:46 pm

Try raising SetAltitude and GravityScale.

MileHighGuy · Post by **MileHighGuy** » Sun Oct 19, 2014 10:48 pm

can anyone define these?

VelocitySpring = 5
VelocityDamp = 2.5
OmegaXSpring = 3.0
OmegaXDamp = 2.5
OmegaZSpring = 5.0
OmegaZDamp = 1.8

EDIT: also this

BodyOmegaXSpringFactor

maybe a general definition of omega in this context would help

I'm still struggling to get the angle of the vehicle to NOT level out at certain inclines

This should help somewhat: viewtopic.php?p=483228#p483228
