Simulating boat drag

Help and Feedback Scripting Support
#1

i created a custom water system and a custom boat bouyancy system but cant figure out how to get the drag working correctly

the linear drag is fine but the angular drag isnt strong enough. i cant make it too strong because then the boat wont be able to turn and i cant make it too weak then the boat will spin out of control

local angularVelocity = -self.moverPart.AssemblyAngularVelocity * Vector3.yAxis
local angularDrag = 5
local angularDrag = (-angularVelocity * self.moverPart.AssemblyMass) * angularDrag
self.dragTorque.Torque = angularDrag

thats what im doing right now. no matter what i do, as soon as the boat starts to rotate it takes forever to stop it

Try squaring the angular velocity and lowering the drag constant. In drag equations, the velocity is often squared.

#3

its still taking a long time to stop spinning

local angularDrag = 50 -- no matter what i change this to the outcome is exactly the same
local angularVelocity = self.moverPart.AssemblyAngularVelocity * Vector3.yAxis
local angularDrag = (-(angularVelocity * angularVelocity) * self.moverPart.AssemblyMass) * angularDrag
self.dragTorque.Torque = angularDrag
