Clamp Y Axis For Camera

[SlipperyBrick]

I have a custom character controller script and I want to clamp the Y axis for my character controller. Right now I can move my mouse down on the Y axis and the camera will let me go completely around on the Y axis, I need to clamp the camera movement to a certain angle.

function Script:Start()
local window = Window:GetCurrent()

--self.camera = players camera
--self.entity = temporary box to use for player movement
--creates a camera in the scene and parents to the entity
self.camera = Camera:Create(self.entity)

--sets the type of the object to player
self.entity:SetKeyValue("type", "player")
local mass = self.entity:GetMass()
if self.entity:GetMass() == 0 then
Debug:Error("Player mass should be greater than 0.")
end

--gets the entity position
local entpos = self.entity:GetPosition(true)

--sets the camera height
self.camera:SetPosition(entpos.x, entpos.y + 1.9, entpos.z, true)

--sets the camera rotation variable
self.camrotation = self.entity:GetRotation(true)
self.camera:SetRotation(self.camrotation.x, self.camrotation.y, 0, true)
mousex = Math:Round(window:GetWidth()/2)
mousey = Math:Round(window:GetHeight()/2)

--sets the camera post processing effects
self.camera:SetFOV(70)
self.camera:AddPostEffect("Shaders/PostEffects/ssao.lua")
self.camera:SetMultisampleMode(4)

end

function Script:UpdateWorld()

local window = Window:GetCurrent()

--gets the position of the mouse
local mouseposition = window:GetMousePosition()
window:SetMousePosition(mousex, mousey)
local dx = mouseposition.x - mousex
local dy = mouseposition.y - mousey
self.camrotation.x = self.camrotation.x + dy / 10
self.camrotation.y = self.camrotation.y + dx / 10
self.camera:SetRotation(self.camrotation.x, self.camrotation.y, 0, true)
end

function Script:UpdatePhysics()
local window = Window:GetCurrent()

--xmove = left/right speed
--zmove = forward/backwards speed
local xmove = 0
local zmove = 0

--key bindings for movement
if window:KeyDown(Key.W) then
zmove = 1
end

if window:KeyDown(Key.S) then
zmove = -1
end

if window:KeyDown(Key.A) then
xmove = -1
end

if window:KeyDown(Key.D) then
xmove = 1
end

self.entity:SetInput(self.camera:GetRotation(true).y, zmove, xmove)
end

 

Here is the script at the moment. Any help is appreciated.

I think you mean clamp the rotation around the X-axis.

Ah perfect, thanks macklebee!

 

Is there a way to stop it from getting all jittery?

 

When I drag my mouse down it hits the value I've put for the clamp but if I continue to drag down the screen goes all jittery, like it's fighting against my mouse to not go past the value I've put in to clamp the camera.

I don't ever remember having that issue. If you run my example shown do you have the same issue? If not, then i would suggest you set your code like my example - most noticeable difference is i set the mouse's position after setting the camera's rotation, not right after getting the mouse's position.

All fixed. I was setting my camera rotation for X axis after the clamping
