Is camera tweening a thing?

Please be aware that Interpolate currently doesn't work correctly in Studio and you should test this in game.

Firstly, :Interpolate takes three arguments: endPosition, endFocusand duration.

This code must be run in a LocalScript and the CameraType must have been set to scriptable.

The endPosition argument is where the camera will physically end up, for example:

local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable
camera:Interpolate(workspace.TestPart.CFrame, someFocusCFrame, 1)

The camera would smoothly tween to the middle of this part.

endFocus is a little different however, endFocus is the position the camera will face when it finishes tweening.

For example:

local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable
local focus = workspace.TestPart.CFrame + workspace.TestPart.CFrame.lookVector
camera:Interpolate(workspace.TestPart.CFrame, focus, 1)
-- this will cause the camera to smoothly tween into the middle of the part and also face the same way as the part.

It can be handy to store an array of parts/Positions to interpolate too, for example:

local targets = {PosOne, PosTwo, PosThree, endFocus}
local duration = 1

for i=1, #targets-1 do
	camera:Interpolate(CFrame.new(targets[i]), CFrame.new(targets[i], targets[i+1]), duration)
	wait(duration)
end

camera.CameraType = Enum.CameraType.Custom
