Spectator camera

[Josh]

Attach this to any camera in the editor and you can fly around and look at things::

Script.movespeed=5.0--float "Move speed"
Script.movementsmoothing = 0.3--float "Move smoothness"
Script.radius = 0.5--float "Radius"
Script.lookspeed = 0.1--float "Look speed"
Script.looksmoothing = 0.5--float "Look smoothness"

function Script:Start()
local window = Window:GetCurrent()
self.mousepos = window:GetMousePosition()
self.camerarotation = self.entity:GetRotation()
if (self.entity:GetMass()==0) then
	self.entity:SetMass(1)
end
self.entity:SetGravityMode(false)
if type(self.entity.SetElasticity)=="SetBuoyancyMode" then
	self.entity:SetBuoyancyMode(false)
end
self.entity:SetCollisionType(Collision.Projectile)
if self.entity:GetShape()==nil then
	local shape = Shape:Sphere(0,0,0, 0,0,0, self.radius*2,self.radius*2,self.radius*2)
	self.entity:SetShape(shape)
	shape:Release()
end
self.entity:SetFriction(0,0)
if type(self.entity.SetElasticity)=="function" then
	self.entity:SetElasticity(0)
end
self.entity:SetSweptCollisionMode(true)
end

function Script:UpdateWorld()
local window = Window:GetCurrent()
local cx = Math:Round(context:GetWidth()/2)
local cy = Math:Round(context:GetHeight()/2)
local mpos = window:GetMousePosition()
window:SetMousePosition(cx,cy)
if self.started then
	mpos = mpos * self.looksmoothing + self.mousepos * (1-self.looksmoothing)
	local dx = (mpos.x - cx) * self.lookspeed
	local dy = (mpos.y - cy) * self.lookspeed		
	self.camerarotation.x = self.camerarotation.x + dy
	self.camerarotation.y = self.camerarotation.y + dx
	self.mousepos = mpos
else
	self.mousepos = Vec3(cx,cy,0)
	self.started=true
end
end

function Script:UpdatePhysics()
local move=0
local strafe=0
local ascension=0
local window = Window:GetCurrent()
if window:KeyDown(Key.W) or window:KeyDown(Key.Up) then move = move + self.movespeed end
if window:KeyDown(Key.S) or window:KeyDown(Key.Down) then move = move - self.movespeed end
if window:KeyDown(Key.D) or window:KeyDown(Key.Right) then strafe = strafe + self.movespeed end
if window:KeyDown(Key.A) or window:KeyDown(Key.Left) then strafe = strafe - self.movespeed end
if window:KeyDown(Key.Q) or window:KeyDown(Key.PageDown) then ascension = ascension - self.movespeed end
if window:KeyDown(Key.E) or window:KeyDown(Key.PageUp) then ascension = ascension + self.movespeed end
local currentvelocity = self.entity:GetVelocity(false)
local desiredvelocity = Vec3(strafe,0,move) + Transform:Vector(0,ascension,0,nil,self.entity)
local velocity = currentvelocity * self.movementsmoothing + desiredvelocity * (1.0-self.movementsmoothing)
self.entity:AddForce((desiredvelocity - currentvelocity) * self.entity:GetMass() / self.movementsmoothing,false)
self.entity:PhysicsSetRotation(self.camerarotation.x,self.camerarotation.y,self.camerarotation.z)
end

Gonna convert this to C++, thanks. Mine acted like a editor camera so this should be better.
