Quick question.

How do I make a 2D camera follow a sprite without making the camera rotate?

 

After you move the sprite each frame, copy its position (with an appropriate offset) to the camera.

 

Can you give the code to that?

 

there is a great Unity Package called Cinemachine
you can find it by opening the Package Manager (Window/PackageManager) in the Unity Editor and installing it there

Cinemachine contains already premade scripts for cameras to follow an object, including some control parameters to define how it shall follow that object, like confinements, damping, dead zones etc:

 

I'm not using a plugin like that. Way to complicated for me. I just want a simpler approach that just makes the camera follow the player without rotation.

 

Really?

Code (csharp):

1. MyCameraTransform.position = MySpriteTransform.position + DesiredCameraOffset;

 

Is cinemachine TPP camera take into account colliders like walls and other occluders ?

 

not sure what TPP is, but yes it sorta has, there is an additional cinemachine Collider component, that if i remember correctly simply moves the camera forward closer to its look-at target up to a non-obstructed line of sight, if something gets in between the camera and the target

though i have never really used that component, just tested it once

it also has confinements where you pretty much define an area the camera (or rather the field of view of the camera) is not allowed to leave, which is super usefull when you have a limited map-size and want to assure that the camera does not see anything out of bounds (like a Top Down or Side scrolling perspective with clear borders)

 

Assuming "third person perspective".
