How to have 2D set space in Unity

Questions & Answers
1

I want to have game space predefined depending on a platform, for example a rectangle space will be the game space, this will be the size of the display. User should be able to view the entire game space in birds eye view.

I am very new to Unity.

Wondering if this is set on camera level.

Please help

The camera would be a good place to limit how far the player can see in a direction. In a code I have used before the function that moves the camera has a Mathf.Clamp in it to keep the screen ‘clamped’ between the min and max positions of the board. A code like this was attached to the update section of the camera script.

Void Update(){
     float mouseX = Input.mousePosition.x;
		float mouseY = Input.mousePosition.y;

Vector3 cameraMouse = new Vector3 (mouseX, mouseY, currentCameraHeight);
				cameraMouse = new Vector3 (Mathf.Clamp(cameraMouse.x, -mapSize, mapSize), Mathf.Clamp(cameraMouse.y, -mapSize, mapSize), currentCameraHeight);
				mainCamera.transform.position = Vector3.Lerp (mainCamera.transform.position, cameraMouse * Time.deltaTime, (Time.deltaTime * smoothSpeed));
				mainCamera.transform.position = new Vector3(mainCamera.transform.position.x, mainCamera.transform.position.y, currentCameraHeight);

You would still have to define some of the variables to use it properly, but it is a place to start.
