2D Camera boundaries C#
I'm making a 2D game that and the Y values for the camera need to be restricted to the edges of the map. I have looked at a lot of other questions regarding the 2D Orthographic camera restriction and I have NO idea what they are talking about. Please note I am new to C# and Unity, so please make an explanation as simple as possible.
If you want "boundaries" you can try Mathf.Clamp which is great for values limitting. Insert this code to Update function.
transform.position = new Vector3
(
Mathf.Clamp (transform.position.x, minimumBoundary.x, maximumBoundary.x),
Mathf.Clamp (transform.position.y, minimumBoundary.y, maximumBoundary.y),
transform.position.z
);
Minimum and maximum boundary are variables of type Vector2. You can declare them as public for easy adjustment while gameplay.
I would avoid clamping because it causes flickering, I would just check the next position and avoid moving it to that position if it leaves your bound. For example I used the follow target script and restricted the new position if it leaves the bounds as such:
if(newPos.x > minX && newPos.x <maxX && newPos.y>minY && newPos.y<maxY)
transform.position = newPos;
By doing that it causes no flickering because it doesn't update the position and then clamp it to a the boundary follow, it just prevents from updating the out of bound position entirely.
