I have a camera. Script puzzle, whee vector programming!

Brand spanking new hobbyist. Not the best programmer; understanding of OOD, not so much vector math. Learning though, and it’s fun! I have a camera.

I position it, transform.position.

I rotate, transform.rotation.

I move it behind and above, .translate(0, 3, -5);

Now it’s in the position I want,the heading I want, matching a “parent” transform. A player. All is good. So far just transform → transform 1:1 matching, displaced. Simple, awesome.

Now rotate camera again - ignoring all previous transformations. How would I do this? Currently I can make a pretty neat 3rd-person camera - by multiplying a quaternion.euler derived from mouse input by the player’s rotation.

cameraTransform.rotation = (playerTransform.rotation * Quaternion.Euler (camRotX, camRotY, 0));

Result: A camera which rotates with the player, and can be rotated around the player by the mouse.

Desired: A camera which rotates with the player, and can be rotated in place at that position.

I’m really drunk right now, so I will probably figure it out some time tomorrow and share my implementation. In the mean time, anyone more experienced - who is not afraid of pseudo-code - your input is welcome warmly. Unfortunately this evening I have pass the point of coder-augmentation-inebriation.

Known hypothetical workaround: Child camera to objectT. Position, rotate, displace objectT camera is attached. Now rotate camera independently. ObjectT is child of player, camera child of objectT; Player motor drives player, objectT follows, camera can rotate. No conflicts.

However this is hamfisted and seems amateur (which I am, so- heh) particularly considering the player will never be separated from these camera conditions.

P.S. where do article adjectives go?
