Local rotation and world rotation

[timber owl]

Can you please help me understand why we use local for the second one and also why not use local for the first one
rotation = Vector3.zero;
rotation.y = lookAngle; // rotation around y axis
targetRotation = Quaternion.Euler(rotation); // Quaternion.Euler(0,lookAngle,0)
transform.rotation = targetRotation; // transform.rotation = Quaternion.Euler(0,lookAngle,0)

rotation = Vector3.zero;
rotation.x = pivotAngle;
targetRotation = Quaternion.Euler(rotation); // Quaternion.Euler(pivotAngle, 0, 0)
cameraPivot.localRotation = targetRotation

also, is there a way to see rotations of both camera manager and camera pivot like this? it would greatly help me understand

wait so tell me if im wrong but what i understood is, if i use rotation, it will rotate around worlds x axis, but when i say local, it rotates around its own x axis

parents own x axis i meant

well i didn't mean that but i changed my mind xD

Hey! I just wanted to say that's exactly what it means. You can probably understand this in a more visual way by changing from local to global (or vice versa) in the scene window by pressing X or changing it manually from the toolbar. If you rotate a game object, you will see that its transform arrows are also rotated while having local selected, but in world space, the arrows will appear always the same.

In this case, you use world space rotation on the Y axis because you want to, regardless its rotation component, turn the camera around the character. But when it comes to the X axis, you probably want to rotate the camera to its sides, but worldspace will be wrong because it will not use your current camera X axis, but the world's one, so if your camera is facing to the ground, the X axis of the world will actually be like the Z axis of the cam, so it will rotate in a unwanted way

i tried changing cameraPivot.localRotation to cameraPivot.rotation and what happens is, when camera manager rotates, camera pivot doesn't rotate even though its parent rotates

so when i say rotation, does it not care about its parents rotation at all?
