Box boundary 2D Unity3D 4.3

Questions & Answers
1

I’m developing snooker like game. So I want to develop Boundary box.One Idea that’s in my mind is creating 4 GameObjects and use theme for each side.
If you have any other good solution please share it.
Thanks in advance

I am not sure but the edge collider might help here (Although I have not used it yet).

Alternatively you could have an image for your bounding area make the center area transparent and apply a polygon collider and edit its verticies so that the center area is not part of the collider.

I have found best code for it.

public class GameSetup : MonoBehaviour
{
	public Camera mainCam = new Camera();

	//Reference the colliders we are going to adjust
	public BoxCollider2D topWall = new BoxCollider2D();
	public BoxCollider2D bottomWall = new BoxCollider2D();
	public BoxCollider2D leftWall = new BoxCollider2D();
	public BoxCollider2D rightWall = new BoxCollider2D();

		// Use this for initialization
		void Start ()
		{
		//Move each wall to its edge location:
		topWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f, 0f)).x, 1f);
		topWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3 ( 0f, Screen.height, 0f)).y + 0.5f);
		
		bottomWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f, 0f)).x, 1f);
		bottomWall.center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3( 0f, 0f, 0f)).y - 0.5f);
		
		leftWall.size = new Vector2(1f, mainCam.ScreenToWorldPoint(new Vector3(0f, Screen.height*2f, 0f)).y);;
		leftWall.center = new Vector2(mainCam.ScreenToWorldPoint(new Vector3(0f, 0f, 0f)).x - 0.5f, 0f);
		
		rightWall.size = new Vector2(1f, mainCam.ScreenToWorldPoint(new Vector3(0f, Screen.height*2f, 0f)).y);
		rightWall.center = new Vector2(mainCam.ScreenToWorldPoint(new Vector3(Screen.width, 0f, 0f)).x + 0.5f, 0f);

	
		}
	
}

Thanks Brackeys :wink:
