Some of our game's rooms will not be able to be fully encapsulated within one screen space. Therefore, we'll have need for a moving camera behavior that will pan to keep the character and a subsection of the room in frame.
Detail
This will involve creating a new script, CameraDolly.cs, which will move the GameObject it is attached to to the position of a target transform (The player position, in most circumstances).
For now, we will acquire the player GameObject by searching for it via a tag- using GameObject.FindGameObjectByTag("player").
Then, in the LateUpdate method, set the attached game object's transform position equal to the target's position.
Remarks:
Verify that the Player GameObject's tag is set to "Player", or else your FindGameObjectByTag method call will fail to find anything.
Be sure to validate the returned value from FindGameObjectByTag. If it returns null, log a warning and be sure to not try and run the code in LateUpdate (We cannot move towards a null target!).
We use LateUpdate rather than Update or FixedUpdate because LateUpdate will occur after all other update ticks. This generally helps reduce the amount of jitter experienced in moving camera systems. Read More
Tasks
[ ] Create a "CameraDolly" GameObject in the scene and make the main camera a child of it.
[ ] Create a CameraDolly.cs script and attach it to the created GameObject above.
[ ] On Start, find the player Transform by their tag and store it as a member variable
[ ] In LateUpdate, if the stored player transform is not null, move the GameObject's position to the player transform position.
