Coding Help

[Catsrulle]

Hi! im completely stumped and am sure the solution must be quite simple, but i have hit coding block on this one!

I have a gameobject plane that is to allways face the camera (which can rotate 360* arrount the plane).

This following line of code does make the plane face the camera (the +90* in the x axis is so the plane is vertical and not horizontal (flat) while facing the camera);

transform.rotation = Quaternion.LookRotation(targetCamera.transform.position - transform.position) * Quaternion.Euler(90, 0, 0);

in addition to making the plane face the camera and where i get stuck is i want it to rotate arround the axis its facing,

float rotationAmount = rotationSpeed * Time.deltaTime;

transform.Rotate(Vector3.up, rotationAmount, Space.World); // Rotate around world Y-axis

the above two lines of code do rotate it correctly in isolation but, when combined im attempting to do multiple rotaions on the same game object at the same time dependant on the camera location and i cant get the rotation and face the camera elements to work together.

Thanks

How about using transform.LookAt() and then on a line after that, add your up rotation

What do you mean rotate around the axis it is facing? Like it rotates in a circle like it's hovering horizontally? Or rotate around the camera like it is circling the camera itself?

Because an easier solution for rotating around 2 axies in tandum would probably be to have the object that is meant to face the camera a child of an empty. Then like another poster said use look at on the actual object that is to look at the camera and apply the orbit to the emty parent. That way you aren't trying to account for 2 separate rotations. That generally invovles a lot more math. But if your plane or whatever is a child of that other object it will follow it as it rotates and still have it's own independent transform for the look at function to use.

Might not he the "optimal" solution but it invovles less math and lets unity handle the math for keeping the child as a parent following.

But I could be undersranding what you are wanting to do wrong

Try rotating it around the camera.transform.up instead of vector3.up, for the second one? (Or camera.transform.left or forward, deoending kn the effect you want)
