[SOLVED]Rotate the camera around the object

[swipis]

heya!

I trying to make a camera rotating around the player.

if window:MouseDown(Key.RButton) then
window:HideMouse()

self.currentMousePos = window:GetMousePosition()
self.currentMousePos.x = Math:Round(self.currentMousePos.x)
self.currentMousePos.y = Math:Round(self.currentMousePos.y)

self.mouseDifference.x = Math:Curve(self.currentMousePos.x - Math:Round(context:GetWidth()/2),self.mouseDifference.x,3)
self.mouseDifference.y = Math:Curve(self.currentMousePos.y - Math:Round(context:GetHeight()/2),self.mouseDifference.y,3)
self.camRotation.x = Math:Clamp(self.camRotation.x + self.mouseDifference.y / self.mouseSensitivity,-90,90)
self.camRotation.y = self.camRotation.y + (self.mouseDifference.x / self.mouseSensitivity)

--Set the camera angle
self.entity:SetRotation(self.camRotation + self.pivot:GetPosition())

else
window:ShowMouse()
end

this code taken from FPS script. what I should do to rotate around player?

thanks

My Leadwerks isn't working at the moment, so I can't test any code. I can only give you pseudo code.

 

You basically want to make the camera work like in the FPS example, but then move its position backwards in local space.

Basically, what you already have there, but add something like:

 

self.entity:SetPosition(self.pivot:GetPosition() + Vec3(0, 0, -10))

 

I'm assuming pivot is where the player is?

yes pivot is players child, what I want to do is make look around player like in the video below (this is my unity project)

 

and code line you gave not helping

 

I found this link but here is very outdated.

Here is a small example of an orbital camera around an object like in the video you posted:

window = Window:Create("Orbital Camera",0,0,800,600,Window.Titlebar+Window.Center)
context = Context:Create(window)
world = World:Create()
camera = Camera:Create()
camera:SetSkybox("Materials/Sky/skybox_texture.tex")
light = DirectionalLight:Create()
light:SetRotation(35,35,0)

player = Model:Load("Models/Characters/generic/generic.mdl")
player:SetColor(0,1,0,1)
pivot = Pivot:Create()
pivot:SetPosition(0,0.8,0)
camera:SetParent(pivot)
camera:Move(0,1,-3)

mx = 0
my = 0
prevmx = 0
prevmy = 0
toggle = 0

while window:KeyDown(Key.Escape)==false do
	if window:Closed() then break end
	if window:MouseHit(Key.RButton) then toggle = 1 end
	if window:MouseDown(Key.RButton) then
		mousepos = window:GetMousePosition()
		mx = pivot:GetRotation().x + (mousepos.y-prevmy)
		my = pivot:GetRotation().y + (mousepos.x-prevmx)
		if toggle==1 then
			toggle = 0
			mx = pivot:GetRotation().x
			my = pivot:GetRotation().y
		end
		pivot:SetRotation(mx,my,pivot:GetRotation().z)
		prevmx = mousepos.x
		prevmy = mousepos.y
	end

	Time:Update()
	world:Update()
	world:Render()
	context:SetBlendMode(Blend.Alpha)
	context:DrawText(string.format("FPS: %.1f",Time:UPS()), 2, 2)
	context:DrawText("Hold Right Mouse Button Down to Rotate", 2, 22)
	context:SetBlendMode(Blend.Solid)
	context:Sync(true)
end
