Spherecast or Raycast diagonally?

Unity Engine

I want to do 4 raycasts diagonally, one between forward and left, left and backward, etc… I have this code right now:

var adjustedPoint : Vector3 = Vector3(hit.point.x, hit.point.y + .5, hit.point.z);
			
			//If building placement location is inside of (or on top of) another obstacle, don't place it
			if (Physics.Raycast (ray, hit, 100, (1 << 10))) {
				obstacleInWay = true;
				Debug.Log("Obstacle in path, building cannot be placed");
			}
			
			//If other buildings are located nearby, don't place the building
			//parameters for spherecast are:  (origin, radius, direction, hitinfo, distance, layerMask)
			//check against positive x
			if (Physics.SphereCast (adjustedPoint, .2, Vector3(1,0,0), hit, 3, (1 << 10))) {        
			 	obstacleInWay = true;
			 	Debug.Log("Obstacle in path, building cannot be placed");    
			}
			//check against negative x
			if (Physics.SphereCast (adjustedPoint, .2, Vector3(-1,0,0), hit, 3, (1 << 10))) {        
			 	obstacleInWay = true;
			 	Debug.Log("Obstacle in path, building cannot be placed");    
			}
			//check against positive z
			if (Physics.SphereCast (adjustedPoint, .2, Vector3(0,0,1), hit, 3, (1 << 10))) {        
			 	obstacleInWay = true;
			 	Debug.Log("Obstacle in path, building cannot be placed");    
			}
			//check against negative z
			if (Physics.SphereCast (adjustedPoint, .2, Vector3(0,0,-1), hit, 3, (1 << 10))) {        
			 	obstacleInWay = true;
			 	Debug.Log("Obstacle in path, building cannot be placed");    
			}

How can I get a diagonal vector between say “Vector3(1,0,0)” and “Vector3(0,0,1)”, the positive x and z direction vectors.

Thanks for any help or ideas.

Nevermind I think I solved it.

It’s just Vector3(1,0,1) for a diagonal direction, or Vector3(-1,0,1)…etc.

Well at least it wasn’t too hard lol.
