Creating an Orbit Camera in Unity in under 5 minutes!

[@ahwendorf2]

This is great! One question, when I try to rotate underneath the gameobject, I get a weird behavior where the camera jitters and flips. Is there a way to fix this?

OH... good focus! that's actually a perfect example for a gimbal lock 😶‍🌫 idk why i never tested this... anyway, here is a script to avoid gimbal lock, using Quaternion for rotation, instead of Vector3 😃 using UnityEngine; public class OrbitCamera : MonoBehaviour { [SerializeField] private Transform target; [SerializeField] private float sensitivity = 5f; [SerializeField] private float orbitRadius = 5f; [SerializeField] private float minimumOrbitDistance = 2f; [SerializeField] private float maximumOrbitDistance = 10f; private float yaw; private float pitch; void Start() { yaw = transform.eulerAngles.y; pitch = transform.eulerAngles.x; } void Update() { if (Input.GetMouseButton(0)) { float mouseX = Input.GetAxis("Mouse X"); float mouseY = Input.GetAxis("Mouse Y"); yaw += mouseX * sensitivity; pitch -= mouseY * sensitivity; transform.rotation = Quaternion.Euler(pitch, yaw, 0); } orbitRadius -= Input.mouseScrollDelta.y / sensitivity; orbitRadius = Mathf.Clamp(orbitRadius, minimumOrbitDistance, maximumOrbitDistance); transform.position = target.position - transform.forward * orbitRadius; } }

@@firedragongamestudio Thank you very much for your prompt and helpful reply! I did not know about gimble lock. Now it rotates all the way around on the x-axis as desired! :D However, now it is doing something else odd. When it is on the "back" (x-rotation between -90 and 90) then the side-to-side rotation is reversed. Any idea how to fix that?

@@ahwendorf2 Just invert the raw X input, when in a certain range of rotation. Smth like this should work: using UnityEngine; public class OrbitCamera : MonoBehaviour { [SerializeField] private Transform target; [SerializeField] private float sensitivity = 5f; [SerializeField] private float orbitRadius = 5f; [SerializeField] private float minimumOrbitDistance = 2f; [SerializeField] private float maximumOrbitDistance = 10f; private float yaw; private float pitch; void Start() { yaw = transform.eulerAngles.y; pitch = transform.eulerAngles.x; } void Update() { if (Input.GetMouseButton(0)) { float mouseX = Input.GetAxis("Mouse X"); float mouseY = Input.GetAxis("Mouse Y"); pitch -= mouseY * sensitivity; bool isUpsideDown = pitch > 90f || pitch < -90f; // Invert yaw input if the camera is upside down if (isUpsideDown) { yaw -= mouseX * sensitivity; } else { yaw += mouseX * sensitivity; } transform.rotation = Quaternion.Euler(pitch, yaw, 0); } orbitRadius -= Input.mouseScrollDelta.y / sensitivity; orbitRadius = Mathf.Clamp(orbitRadius, minimumOrbitDistance, maximumOrbitDistance); transform.position = target.position - transform.forward * orbitRadius; } }

I signed up for the highest tier. Can I get the script?

[@firedragongamestudio]

Sure, check out the channel community tab. There is a post for posting Github usernames. I can share the code either directly in the comments there, or send you a link for a Repo. 🙂

[@firedragongamestudio]

Are you still interested? You haven't sent me your Github username, for code sharing yet.

[@anotherangle3dvisuals608]

And can you please provide us with the script? Thanks!

[@firedragongamestudio]

As mentioned in the video, direct source code access is only available for channel members, but you can pause the video and just type it from the screen :)

@@firedragongamestudioNo worries. Thanks. Are you perhaps available for custom c# Unity coding? Contact me, thanks.
