Camera Clamp Setup

Questions & Answers
1

Hi, I’d like my camera to always stay/show within the borders of a background (made of multiple game objects).

The basic element of my game is a Unity Sprite of 64 x 64 pixels.

That said. I know the position of the bottom left element (that is a gameobject with 64x64 sprite) and the top right (same type of game Object is a 64x64 sprite).
Example:

The position of these elements may change depending on the scene level. But they will stay fixed for all the scene, so I need to adjust this just after each level loading.

How can I clamp the camera between these 2 gameobjects (to avoid showing outside elements in the view)?

Thank you very much in advance.

I am REALLY NOT sure if this is gonna work…

using...blah blah blah

public class Clamp : MonoBehaviour
{
    public GameObject bound_one; //assign in in the editor
    public GameObject bound_two; //assign in in the editor
    public Camera cam; // --

    private float BOposX;
    private float BOposY;
    private float BTposX;
    private float BTposY;
    
    void Update()
    {
        float xPos = Mathf.Clamp(xPos, BOposX, BTposX);
        float yPos = Mathf.Clamp(xPos, BOposY, BTposY);

        cam.transform.localPosition = new Vector3(xPos, yPos, 0);

        //if the localPosition line above does not work, try:
        cam.transform.position = new Vector3(cam.transform.position.x + xPos, cam.transform.position.y + yPos, 0);
    }
}

Sorry if this is totally wrong. Just place the Boundary GameObjects (you can create empty) in the needed places and it could somehow work. :slight_smile:
