Cinemachine look ahead with mouse

I'm currently working on a twin stick shooter, and I want camera behavior similar to enter the gungeon's, where you can adjust the camera's position with the mouse, but always keep the player on screen. I'm wondering how I could achieve this effect with cinemachine2D. I know there's a lookahead feature in cinemachine, but I'm unsure how to manipulate this with anything other than the follow object. My only idea would be to create two virtual camera's and have one follow the player, and the other follow an empty with the mouse position, while somehow having the camera stay in between the two. I don't know if this is right, and if it is, i don't know how to do it. Any insight would help a lot!

 

Can't you create a vector between the mouse cursor and the player, and then focus Cinemachine on the midpoint of the vector? And then you could use the "between" vector to ensure that the player and the cursor isn't too far apart.

 

So I had this same question for a 2D game and this is how I implemented it (for anyone else who wants to know how to do this). Like what PGJ said, you find the midpoint (or quarter-point if you will) between your unit and mouse. Since Cinemachine requires a transform, you will probably need an empty GameObject for the Cinemachine to follow. As a result, set the empty GameObject's transform to the position that you want, and simply follow that GameObject instead of your unit. Here are some images of the code and end result.

 

I made a formula (on line 10):

Code (CSharp):

1. public class CameraTarget : MonoBehaviour
2. {
3.         [SerializeField] private Transform playerTransform;
4.         [SerializeField] private Camera mainCamera;
5.         [Range(2, 100)] [SerializeField] private float cameraTargetDivider;
6.  
7.         private void Update()
8.         {
9.             var mousePosition = mainCamera.ScreenToWorldPoint(Input.mousePosition);
10.             var cameraTargetPosition = (mousePosition + (cameraTargetDivider - 1) * playerTransform.position) / cameraTargetDivider;
11.             transform.position = cameraTargetPosition;
12.         }
13. }

 

thank you, I couldn't even get chatGPT to figure that out lol!
