How would I make a smoother first person camera?

So the current Roblox Camera code seems to skip tiny angles, this is really only noticable when reducing the field of view, or trying to move your camera in small increments.

I found one method was to simply change the camera from Pointing in the desired direction and instead lerping it towards its intended direction.

This smoothed the camera, but introduced roll. I used:

`1`	`workspace.CurrentCamera.CoordinateFrame` `=` `workspace.CurrentCamera.CoordinateFrame:lerp(this.cframe,script.Parent.Parent.Stats.Zoom.Value)`

this.CFrame is the new rotated camera CFrame. Zoom being how much the camera's field of view was divided by 20-30, to simulate lowering sensitivity.

While this works really well, it still jumps these small increments, and that is really annoying, ontop of also lagging behind the player.

I've read the wiki article, and tried to look about online to find a source on creating mouse movement, but sadly can't find anything. Does anyone know where I should start looking?

My personal way is using a custom lerp. (clerp) (Bit more advanced method)

1local function clerp(p1,p2,percent)
2            local p1x,p1y,p1z,p1R00,p1R01,p1R02,p1R10,p1R11,p1R12,p1R20,p1R21,p1R22 = p1:components()
3            local p2x,p2y,p2z,p2R00,p2R01,p2R02,p2R10,p2R11,p2R12,p2R20,p2R21,p2R22 = p2:components()
4            return
5                CFrame.new(p1x+percent*(p2x-p1x), p1y+percent*(p2y-p1y) ,p1z+percent*(p2z-p1z),
6                (p1R00+percent*(p2R00-p1R00)), (p1R01+percent*(p2R01-p1R01)) ,(p1R02+percent*(p2R02-p1R02)),
7                (p1R10+percent*(p2R10-p1R10)), (p1R11+percent*(p2R11-p1R11)) , (p1R12+percent*(p2R12-p1R12)),
8                (p1R20+percent*(p2R20-p1R20)), (p1R21+percent*(p2R21-p1R21)) ,(p1R22+percent*(p2R22-p1R22)))
9        end

http://wiki.roblox.com/index.php?title=Magnitude Example of my clerp.. (client)

01local cam = workspace.CurrentCamera
02local part1 = workspace.Part1
03local char = workspace:WaitForChild(game.Players.LocalPlayer.Name)
04local rs = game:GetService("RunService").RenderStepped
05 
06cam.CameraType="Scriptable" -- Make the camera scriptable
07 
08for i = 1, ((part1.Position - char.Torso.Position).magnitude), 1 do
09    cam.CoordinateFrame = clerp(
10        cam.CoordinateFrame,
11        part1.CFrame
12    ,.02)
13    rs:wait()
14end

-- HOW MY CLERP WORKS -- It runs all off of CFrame, thus to change the camera position. (VERY smoothly) http://wiki.roblox.com/index.php?title=CFrame http://prntscr.com/ajzsh1

Lets use CoordinateFrame because it runs on CFrame.

`1`	`camera.CoordinateFrame`

Now, since my clerp returns a CFrame, we need to do this..

`1`	`camera.CoordinateFrame` `=` `clerp( a, b, c )`

The first arg of my clerp needs to be a CFrame, the CFrame we will be using

`1`	`camera.CoordinateFrame` `=` `clerp( camera.CoordinateFrame , b, c )`

The second arg of my clerp need to be the CFrame YOU WANT

`1`	`camera.CoordinateFrame` `=` `clerp( a , CFrame.new(9,576,50) , c )`

The last bit of my clerp (#arg 3) needs to be a decimal. Such as .01 - 1 This last arg will determine how quick the (and smooth) the movement will be

`1`	`camera.CoordinateFrame` `=` `clerp( a , b , .02` `)`

I have already set up the correct camera interpolation decimal, but change it if you need. :)

Not really, clerps are MUCH faster then normal lerp. Plus its just smoother. The for i loop I made quickly because Im on tablet lol Im_Nick 30 — 9y

Least I took my own time and will into making a custom lerp. Im_Nick 30 — 9y

So what's the difference between clerping all the constructors of a CFrame rather than doing it with just the X,Y,Z Coords and eulear angles? LateralLace 297 — 9y

With a clerp you can pick and choose perfect angles while getting the smoothest usage possible. X.Y.Z could be used I would guess, but not as smooth as a custom clerp. Im_Nick 30 — 9y
