Raycasting crashing Unity?

I've got a script that (while a player hasn't been sighted) sends out various raycasts. If one of these raycasts hits a player, the loop ends and the AI should begin to give chase. The chase portion of the script does nothing right now, but something is causing Unity to crash when I click "play".

Edit: Despite using the code format button, my code formatting gets destroyed. Any help with making that more readable would be appreciated, too. ;]

void Search(){ RaycastHit hit;

Vector3 rayPos = transform.Find ("rayPos").position;

Vector3 right15 = Quaternion.Euler(0, 15, 0) transform.forward; Vector3 right30 = Quaternion.Euler(0, 30, 0) transform.forward; Vector3 right45 = Quaternion.Euler(0, 45, 0) * transform.forward;

Vector3 left15 = Quaternion.Euler (0, -15, 0) transform.forward; Vector3 left30 = Quaternion.Euler (0, -30, 0) transform.forward; Vector3 left45 = Quaternion.Euler (0, -45, 0) * transform.forward;

// [LINE OF SIGHT CHECKS] // Forward

while(playerSighted != true){ // Forward if(Physics.Raycast(rayPos, transform.forward, out hit, 30.0f)){ Debug.Log("Hit: 0 Degrees"); Debug.DrawLine(rayPos, hit.point, Color.green); if(hit.collider.tag == "Player"){ playerSighted = true; } }

// 15 degrees right if(Physics.Raycast(rayPos, right15, out hit, 26.0f)){ Debug.Log ("Hit: 15 Degrees"); Debug.DrawLine(rayPos, hit.point, Color.green); if(hit.collider.tag == "Player"){ playerSighted = true; } }

// 30 Degrees right if(Physics.Raycast(rayPos, right30, out hit, 22.0f)){ Debug.Log ("Hit: 30 Degrees"); Debug.DrawLine(rayPos, hit.point, Color.green); if(hit.collider.tag == "Player"){ playerSighted = true; } }

// 45 Degrees right if(Physics.Raycast(rayPos, right45, out hit, 18.0f)){ Debug.Log ("Hit: 45 Degrees"); Debug.DrawLine(rayPos, hit.point, Color.green); if(hit.collider.tag == "Player"){ playerSighted = true; } }

// 15 degrees left if(Physics.Raycast(rayPos, left15, out hit, 26.0f)){ Debug.Log ("Hit: -15 Degrees"); Debug.DrawLine(rayPos, hit.point, Color.green); if(hit.collider.tag == "Player"){ playerSighted = true; } }

// 30 degrees left if(Physics.Raycast(rayPos, left30, out hit, 22.0f)){ Debug.Log ("Hit: -30 Degrees"); Debug.DrawLine(rayPos, hit.point, Color.green); if(hit.collider.tag == "Player"){ playerSighted = true; } }

// 45 degrees left if(Physics.Raycast(rayPos, left45, out hit, 18.0f)){ Debug.Log ("Hit: -45 Degrees"); Debug.DrawLine(rayPos, hit.point, Color.green); if(hit.collider.tag == "Player"){ playerSighted = true; } } }

if(playerSighted == true){ Chase(); }

}

Apologies for that being lengthy. Any ideas would be greatly appreciated. Thanks!
