Shock absorbers have a strange behavior

How can I avoid this behavior?
 

Script Lua.


 

Script.rueda = nil --entity "Rueda"
Script.chassis = nil --entity "Chassis"




function Script:Start()
	
	
    self.posAmortiguador = self.entity:GetPosition()
	
	
	self.Amortiguador    = Joint:Slider(self.posAmortiguador.x, self.posAmortiguador.y, self.posAmortiguador.z, 0,1,0, self.entity, self.chassis)
	self.Amortiguador:SetSpring(200 )
	
	self.Amortiguador:EnableLimits()
	
	self.Amortiguador:SetLimits( 0, 0.01) 
	self.Amortiguador:EnableMotor()
	self.Amortiguador:SetTargetAngle(0)
	
	self.posMotor        = self.rueda:GetPosition()
	self.Motor           =  Joint:Hinge( self.posMotor.x, self.posMotor.y, self.posMotor.z, 0, 0, 1, self.rueda, self.entity ) 
	self.Motor:DisableLimits()
	
	self.rueda:SetPickMode( 0 )
	self.entity:SetPickMode( 0 ) 
	
	self.rueda:SetFriction(1, 1 ) 
	
end


local vel = 0
function Script:UpdateWorld()
	
	self.Motor:DisableMotor()
	if window:KeyDown(Key.W) then 
	
	  self.Motor:EnableMotor()
	  self.Motor:SetAngle( self.Motor:GetAngle() - 100 ) 
	
	  
		if vel <=500 then 
			vel = vel + 10 
	
		end 
	

	
	
	
	
	end 
	
	
	
  if window:KeyDown(Key.S) then 
	
	  self.Motor:EnableMotor()
	  self.Motor:SetAngle( self.Motor:GetAngle() + 100 ) 
	
	  
		if vel <=500 then 
			vel = vel + 10 
	
		end 
	

	
	
	
	
	end 


	self.Motor:SetMotorSpeed( vel ) 

	
end

  • Solution

You can see that since you are using a motor instead of a spring, the correction force is constant. A spring would increase the force as it gets further from the equilibrium point. I will be looking at the spring damper soon to see if we can minimize bouncing / harmonics.

My job is to make tools you love, with the features you want, and performance you can't live without.

I'm telling you that if he didn't activate the engine, he's still bouncing the tires a lot, even if he puts a value of 1 in the spring. 

I'm going to make a video to explain it better, the thing is that the translator doesn't help me much.

Here video. 

I believe you. Newton has three parameters for the spring. I only exposed one and automatically filled in the other two. Obviously I need to expose all three.

Thank you, the truth is that the translator is often a real problem.

Spring to Spanish equals "Primavera"

"Primavera" in Spanish I understand is a time of year, along with winter, fall and summer.  That's why I think the best way is to make the videos.

¿Elástico? ¿Eso tiene más sentido?

If perfect, I have understood it by force, try after try, a spring, the same happens with certain words, for example Handle tells me that it is a green tropical fruit. I suppose everything would be easier if he spoke English, but I think that with the persistence I already have a car system that I imagined impossible before, and it all started with your suggestion of springs, sliding joints and hinge joints.
