Add colliders to screen edge.

Questions & Answers
1

I am building a simple single screen game (pong just to do a project without a tutorial) and i want it to work on multiple resolutions. Therefore i need to attatch colliders and paddles to the screen edges. Is there any simple way to do this?

void GenerateCollidersAcrossScreen()
{
Vector2 lDCorner = camera.ViewportToWorldPoint(new Vector3(0, 0f, camera.nearClipPlane));
Vector2 rUCorner = camera.ViewportToWorldPoint(new Vector3(1f, 1f, camera.nearClipPlane));
Vector2 colliderpoints;

    EdgeCollider2D upperEdge = new GameObject("upperEdge").AddComponent<EdgeCollider2D>();
    colliderpoints = upperEdge.points;
    colliderpoints[0] = new Vector2(lDCorner.x, rUCorner.y);
    colliderpoints[1] = new Vector2(rUCorner.x, rUCorner.y);
    upperEdge.points = colliderpoints;

    EdgeCollider2D lowerEdge = new GameObject("lowerEdge").AddComponent<EdgeCollider2D>();
    colliderpoints = lowerEdge.points;
    colliderpoints[0] = new Vector2(lDCorner.x, lDCorner.y);
    colliderpoints[1] = new Vector2(rUCorner.x, lDCorner.y);
    lowerEdge.points = colliderpoints;

    EdgeCollider2D leftEdge = new GameObject("leftEdge").AddComponent<EdgeCollider2D>();
    colliderpoints = leftEdge.points;
    colliderpoints[0] = new Vector2(lDCorner.x, lDCorner.y);
    colliderpoints[1] = new Vector2(lDCorner.x, rUCorner.y);
    leftEdge.points = colliderpoints;

    EdgeCollider2D rightEdge = new GameObject("rightEdge").AddComponent<EdgeCollider2D>();

    colliderpoints = rightEdge.points;
    colliderpoints[0] = new Vector2(rUCorner.x, rUCorner.y);
    colliderpoints[1] = new Vector2(rUCorner.x, lDCorner.y);
    rightEdge.points = colliderpoints;
