Player Camera - is a flexible component that can follow the player’s position and rotation on different axes.
Target - reference to the target the camera will follow.
Offset - camera offset to target or pivot.
Pivot - point around which the camera will rotate.
Movement Speed - position change speed.
Follow Position X\Y\Z - turn on and off position following on certain axis.
Rotation Speed - rotation change speed.
Follow Rotation X\Y\Z - turn on and off rotation following on certain axis.
Try Find Player - will itself find a link to the target if the player has a tag Player.
Try Find Pivot - will itself find a pivot reference if the pivot is the only parent of the camera.
ADVICE: Arcade idle games often use camera position following on X and Z, without rotation following.
NOTICE: Pivot is needed when you need to follow the player rotation Y. For example, first video without pivot, second with pivot.
