Getting the Wheel SEnt to move(Spawned by my own SEnt)

[Ronon Dex]

Hi, i'm making an entity which needs wheels so it can move. But for some reason the wheels won't move at all. Here's my code:
[lua]
function ENT:SpawnWheels()

local model = "models/madjawa/malp/malpwheel.mdl"
local pos = {}
pos[1] = self:GetPos()+self:GetRight()*-25+self:GetUp()*-5+self:GetForward()*5
pos[2] = self:GetPos()+self:GetRight()*25+self:GetUp()*-5+self:GetForward()*5
pos[3] = self:GetPos()+self:GetRight()*25+self:GetForward()*40+self:GetUp()*-5
pos[4] = self:GetPos()+self:GetRight()*-25+self:GetForward()*40+self:GetUp()*-5
pos[5] = self:GetPos()+self:GetRight()*25+self:GetForward()*-30+self:GetUp()*-5
pos[6] = self:GetPos()+self:GetRight()*-25+self:GetForward()*-30+self:GetUp()*-5

local ang = {}
ang[1] = self:GetAngles()+Angle(90,0,0)
ang[2] = self:GetAngles()+Angle(-90,180,0)
ang[3] = self:GetAngles()+Angle(-90,180,0)
ang[4] = self:GetAngles()+Angle(90,0,0)
ang[5] = self:GetAngles()+Angle(-90,180,0)
ang[6] = self:GetAngles()+Angle(90,0,0)

for i=1,6 do
local e = ents.Create("gmod_wheel")
e:SetModel(model)
e:SetPos(pos[i])
e:SetAngles(ang[i])
e:Spawn()
e:Activate()
e:SetOwner(self)
e.Motor=self
e.Motor.forcescale=1
--e:SetParent(self)
constraint.Weld(e,self,0,0,0,true)
self.MalpWheels[i]=e
end
end

function ENT:OnRemove()
for i=1,6 do
self.MalpWheels[i]:Remove()
end
end

function ENT:Think()

if(self.Control) then
if(self.Controler:KeyDown(IN_FORWARD)) then
print("See i told you so")
for i=1,6 do
self.MalpWheels[i].Motor.direction=1
self.MalpWheels[i]:SetTorque(10000)
self.MalpWheels[i].Toggle=true
self.MalpWheels[i].ToggleState=true
end
self:MoveForward()
print("bah humbug")
end

if(self.Controler:KeyDown(IN_MOVELEFT)) then
self:TurnLeft()
elseif(self.Controler:KeyReleased(IN_MOVELEFT)) then
self.Rotated=false
end

if(self.Controler:KeyDown(IN_MOVERIGHT)) then
self:TurnRight(plus)
end
end
end

function ENT:MoveForward()

if(ValidEntity(self)) then
for i=1,6 do
self.MalpWheels[i]:Forward(true,1)
end
end
end
[/lua]

Any ideas?

You could just spawn the wheel as a prop_physics and then use AddAngleVelocity.

[lua]
local phys = wheel:GetPhysicsObject()
local dir = wheel:GetForward() --Angle or vector
phys:AddAngleVelocity( dir * Torque )
[/lua]

I'll try that thanks

It doesn't move my entity for some reason. I see dust from the wheel prop as if it's trying to move and the whole thing wobbles about but nothing else happens. Here's my code again:

Wheel SEnt:
[lua]

include("shared.lua")
AddCSLuaFile("shared.lua")
AddCSLuaFile("cl_init.lua")

function ENT:SpawnFunction(pl,tr)
if (!tr.HitWorld) then return end;
local e = ents.Create("malp_wheel");
e:Spawn();
e:Activate();
return e;
end

function ENT:Initialize()

self:SetModel("models/madjawa/malp/malpwheel.mdl")
self:PhysicsInit( SOLID_VPHYSICS )
self:SetMoveType( MOVETYPE_VPHYSICS )
self:SetSolid( SOLID_VPHYSICS )

self.Phys = self:GetPhysicsObject()

end

function ENT:MoveForward(b)

if(ValidEntity(self)) then
if(b) then
local phys = self:GetPhysicsObject()
local dir = self:GetForward()
phys:AddAngleVelocity(dir*10000)
end
end
end
[/lua]

My Entity:
[lua]

function ENT:SpawnWheels()

local model = "models/madjawa/malp/malpwheel.mdl"
local pos = {}
pos[1] = self:GetPos()+self:GetRight()*-25+self:GetUp()*-5+self:GetForward()*5
pos[2] = self:GetPos()+self:GetRight()*25+self:GetUp()*-5+self:GetForward()*5
pos[3] = self:GetPos()+self:GetRight()*25+self:GetForward()*40+self:GetUp()*-5
pos[4] = self:GetPos()+self:GetRight()*-25+self:GetForward()*40+self:GetUp()*-5
pos[5] = self:GetPos()+self:GetRight()*25+self:GetForward()*-30+self:GetUp()*-5
pos[6] = self:GetPos()+self:GetRight()*-25+self:GetForward()*-30+self:GetUp()*-5

local ang = {}
ang[1] = self:GetAngles()+Angle(90,0,0)
ang[2] = self:GetAngles()+Angle(-90,180,0)
ang[3] = self:GetAngles()+Angle(-90,180,0)
ang[4] = self:GetAngles()+Angle(90,0,0)
ang[5] = self:GetAngles()+Angle(-90,180,0)
ang[6] = self:GetAngles()+Angle(90,0,0)

for i=1,6 do
local e = ents.Create("malp_wheel")
e:SetPos(pos[i])
e:SetAngles(ang[i])
e:Spawn()
e:Activate()
-- e:SetOwner(self)
-- e:SetParent(self)
constraint.Weld(e,self,0,0,0,true)
self.MalpWheels[i]=e
end
end

function ENT:OnRemove()
for i=1,6 do
self.MalpWheels[i]:Remove()
end
end

function ENT:Think()

if(self.Control) then
if(ValidEntity(self.Controler)) then
for i=1,6 do
if(self.Controler:KeyDown(IN_FORWARD)) then
self.MalpWheels[i]:MoveForward(true)
else
self.MalpWheels[i]:MoveForward(false)
end
end

if(self.Controler:KeyDown(IN_MOVELEFT)) then
self:TurnLeft()
elseif(self.Controler:KeyReleased(IN_MOVELEFT)) then
self.Rotated=false
end

if(self.Controler:KeyDown(IN_MOVERIGHT)) then
self:TurnRight()
end
end
end
end
[/lua]

This is getting quite annoying now

I have figured out that the reason it's not moving is because the wheels are welded(Duh im soo stupid) to the entity. Problem is if i use [lua]e:SetParent(self)[/lua] the wheel's lose collision. what else can i do?

It seems like you are just not using enough force to make it move.

Applying physical forces in the think function can make the movement a bit choppy since it only runs about 5 times per second (at least on my computer it's a 0.22 sec delay). You can solve this by changing how often the think function should run or you can do it in another function that runs more often.

You can also help the vehicle move by applying force on it or you could just use the physics simulate func.

[lua]
--0 is neutral, -1 is backwards and 1 is forward
ENT.LeftWheelRow = 0
ENT.RightWheelRow = 0

function ENT:PhysicsUpdate( physics )

if self.LeftWheelRow != 0 then
local dir = some kind of direction
for i = 1, NrOfLeftWheels do
local phys = self.LefWheels[i]:GetPhysicsObject()
local dir = self:GetForward()
phys:AddAngleVelocity(dir * Torq * self.LeftWheelRow )
end
end

if self.RightWheelRow != 0 then
local dir = some kind of direction
for i = 1, NrOfRightWheels do
local phys = self.LefWheels[i]:GetPhysicsObject()
local dir = self:GetForward()
phys:AddAngleVelocity(dir * Torq * self.RightWheelRow )
end
end

end

function ENT:Think()

if(self.Control) then
if(ValidEntity(self.Controler)) then
if(self.Controler:KeyDown(IN_FORWARD)) then
self.LeftWheelRow = 1
self.RightWheelRow = 1
elseif(self.Controler:KeyDown(IN_BACK)) then
self.LeftWheelRow = -1
self.RightWheelRow = -1
else
self.LeftWheelRow = 0
self.RightWheelRow = 0
end

if(self.Controler:KeyDown(IN_MOVELEFT)) then
self.LeftWheelRow = -1
self.RightWheelRow = 1
elseif(self.Controler:KeyReleased(IN_MOVERIGHT)) then
self.LeftWheelRow = 1
self.RightWheelRow = -1
end
end
end
end
[/lua]

It just sort of wobbles on the spot if i do that, and the torque is at 100000000000000000000 and still doesnt go forward
