[4.6] Sliding Door Script Start Open (With Fix)

[reepblue]

Simple script issue where the stock Sliding Door script no longer starts open when told to do so out of the box. This is my Start function fix. If you think of anything better, let me know.

function Script:Start()
	self.entity:SetGravityMode(false)
	if self.entity:GetMass()==0 then
		Debug:Error("Entity mass must be greater than 0.")
	end

	self.sound={}

	if self.opensoundfile~="" then self.sound.open = Sound:Load(self.opensoundfile) end
	if self.loopsoundfile~="" then self.sound.loop = Sound:Load(self.loopsoundfile) end
	if self.closesoundfile~="" then self.sound.close = Sound:Load(self.closesoundfile) end
	
	if self.sound.loop~=nil then
		self.loopsource = Source:Create()
		self.loopsource:SetSound(self.sound.loop)
		self.loopsource:SetLoopMode(true)
		self.loopsource:SetRange(50)
	end

	if self.manualactivation==false then self.Use=nil end

	self.opentime=0
	
	--Create a motorized slider joint
	local position=self.entity:GetPosition(true)
	local pin=self.distance:Normalize()
	self.joint=Joint:Slider(position.x,position.y,position.z,pin.x,pin.y,pin.z,self.entity,nil)
	self.openangle=self.distance:Length()
	self.closedangle=0

	if self.openstate then
		self.entity:SetPosition(position+self.distance)
		self.joint:SetAngle(self.openangle)
	end

	self.joint:EnableMotor()
	self.joint:SetMotorSpeed(self.movespeed)
end

It looks good on first try but I want to think about this some more and decide what the correct behavior should be.

For what it's worth.  We have begun some further work on Forth Project (in game projects).  We found some oddities with physics where platforms were floating up that previously were stationary.  It isn't code I wrote, haven't looked closely at it, and I'm focusing on some modelling at the minute so I don't have any info on what the cause is.  I am sticking with 4.5 for this project.

I am just reporting it to inform that there do seem to be some differences physics between 4.5 and 4.6.  If I get to investigating that I'll update or if there are changes in 4.6 we can probably check against our know problem area in Forth as an extra test bed.
