vehicle_monstertruck.lua_tireOrder

[flachdrache]

I noticed that the tires of the leadwerks_monstertruck are called in a wrong order - assuming its left-left, right-right :

 

vehicle_monstertruck.lua

 

require("scripts/class")
require("scripts/loop")
require("scripts/math/math")

local class=CreateClass(...)

function class:CreateObject(model)
local object=self.super:CreateObject(model)	

function object:UpdateMatrix()
	self:UpdateTires()
end

function object:UpdateTires()
	local speed
	for n=0,3 do
		if self.tire[n]~=nil then
			self.tire[n]:SetMatrix( self.vehicle:GetTireMatrix(n) )
			if self.emitter[n]~=nil then
				self.emitter[n]:SetMatrix(self.vehicle:GetTireMatrix(n))
				self.emitter[n]:Pause()
				if self.vehicle:TireIsAirborne(n)==0 then
					speed = math.abs(self.model:GetVelocity(0).z)
					speed = (speed - 4) * 20.0
					speed = Clamp( speed, 0, 1 ) * 0.5
					if speed>0 then
						self.emitter[n]:Resume()
						self.emitter[n]:SetColorf(1,1,1,speed)
					end
				end
			end
		end
	end
end

local pivot
local suspensionlength=0.1
local springconstant=25.0
local springdamper=115.0

object.vehicle=CreateVehicle(object.model)
object.tire={}
object.emitter={}

pivot=object.model:FindChild("tireL1")
if pivot~=nil then
	tireradius=pivot.aabb.h/2.0
	object.vehicle:AddTire(TFormPoint(pivot.position,pivot.parent,model),tireradius,suspensionlength,springconstant,springdamper)
	object.tire[0]=LoadMesh("abstract::vehicle_monstertruck_tire_left.gmf",object.model)
	pivot:Hide()
end

pivot=object.model:FindChild("tireR1")
if pivot~=nil then
	tireradius=pivot.aabb.h/2.0
	object.vehicle:AddTire(TFormPoint(pivot.position,pivot.parent,model),tireradius,suspensionlength,springconstant,springdamper)
	object.tire[2]=LoadMesh("abstract::vehicle_monstertruck_tire_left.gmf",object.model)
	pivot:Hide()
end	

pivot=object.model:FindChild("tireL2")
if pivot~=nil then
	tireradius=pivot.aabb.h/2.0
	object.vehicle:AddTire(TFormPoint(pivot.position,pivot.parent,model),tireradius,suspensionlength,springconstant,springdamper)
	object.tire[1]=LoadMesh("abstract::vehicle_monstertruck_tire_right.gmf",object.model)
	pivot:Hide()
end


pivot=object.model:FindChild("tireR2")
if pivot~=nil then
	tireradius=pivot.aabb.h/2.0
	object.vehicle:AddTire(TFormPoint(pivot.position,pivot.parent,model),tireradius,suspensionlength,springconstant,springdamper)
	object.tire[3]=LoadMesh("abstract::vehicle_monstertruck_tire_right.gmf",object.model)
	pivot:Hide()
end	

object.emitter={}
object:UpdateTires()

if world_transparency~=nil then
	if world_main~=nil then
		SetWorld(world_transparency)
		for n=0,3 do
			if object.tire[n]~=nil then
				object.emitter[n]=CreateEmitter(50,2000,Vec3(0,1,0),0,object.tire[n])
				object.emitter[n]:SetPosition(Vec3(0,-object.tire[n].aabb.h/2.0,0))
				object.emitter[n]:SetParent(model,1)
				object.emitter[n]:SetRadius(1,6)
				object.emitter[n]:SetWaver(1.0)
				object.emitter[n]:Paint(LoadMaterial("abstract::roaddust.mat"))
				object.emitter[n]:SetRotationSpeed(0.1)
				object.emitter[n]:Pause()
			end
		end
		SetWorld(world_main)
	end
end

object.model.buoyant=0
object.model:SetKey("collisiontype",COLLISION_PROP)
object.model:SetKey("mass",1.2)
object:UpdateTires()
end

 

which makes the driver_Truck.lua :

PS: changed KEY_UP etc. to KEY_W etc. in this script.

Thank's for the info TLD, i knew something was mesed up in that script.

I just suck with lua scripting, so i never fixed it.

[Marleys Ghost]

Yep, thanks for the share TLD I am sure that is going to come in handy

[ZeroByte]

Since there is no LoadScript in c++ anymore, How could i get this to run in my c++ project?

 

I'm using LEO with support for Lua, from example Lummoja posted. Just plain project with character controller.

 

If i drag the monstertruck into my map, i see it's in there rolling around, but how do i load the "driver_truck.lua" script?

 

 

 

Thank's for any tips..

Page 21 talks about that

Thank's for the link VicToMeyeZR, i have my project setup like that.

 

I think i was confusing the "driver_truck.lua" script with the "vehicle_monstertruck.lua" script.
