3rd person to first person camera

[Rick]

I'm trying to switch from 3rd person camera to first person camera which is really zoomed in over the should but I want it to behave like a first person.

 

The below code is attached to a camera object in the scene which isn't a child of anything else. My thought was for 3rd I move the camera to the player location, rotate it, then offset it with move. When I want to go to first person my thought was move the camera to the player location, offset it with move, THEN rotate it in hopes that it would be rotating in the new over the shoulder position and not like in 3rd person. This however isn't what is happening. These both seem to be giving the same results.

 

if self.zoomed == false then
   -- move the camera to the player
   self.entity:SetPosition(self.Character:GetPosition(true))

   -- set the rotation of the camera
   self.entity:SetRotation(Vec3(self.cameraPitch, self.cameraYaw, 0), true)

   -- offset the camera
   self.entity:Move(self.xDistance, self.yDistance, -self.zDistance)
else
   -- move the camera to the player
   self.entity:SetPosition(self.Character:GetPosition(true))

   -- offset the camera
   self.entity:Move(self.xDistance, self.yDistance, -self.zDistance)

[size=4]    -- set the rotation of the camera[/size]
   self.entity:SetRotation(Vec3(self.cameraPitch, self.cameraYaw, 0), false)
end

I got it. It was holding the pitch and yaw from the 3rd person view still. So I reset the rotation but keep the yaw because that keeps the camera over the shoulder but by resetting the pitch before moving the camera gives me a FPS style when looking up and down, which is what I wanted. Now I'll rotate the waist by the same pitch and it should give a nice effect when in first person. Final code is:

 

if self.zoomed == false then
   -- move the camera to the player
   self.entity:SetPosition(self.Character:GetPosition(true))

   -- set the rotation of the camera
   self.entity:SetRotation(Vec3(self.cameraPitch, self.cameraYaw, 0), true)

   -- offset the camera
   self.entity:Move(self.xDistance, self.yDistance, -self.zDistance)
else
   -- move the camera to the player
   self.entity:SetPosition(self.Character:GetPosition(true))
   self.entity:SetRotation(Vec3(0, self.cameraYaw, 0))

   local pos = self.entity:GetPosition(true)

   -- offset the camera
   self.entity:Move(self.xDistance, self.yDistance, -self.zDistance)

   -- set the rotation of the camera
   self.entity:SetRotation(Vec3(self.cameraPitch, self.cameraYaw, 0))
end
