unity3d - Position wall of arrows in front of player -

i having difficulty positioning wall of objects(arrows) in front of player. want solid wall of arrows shot in front of player perpendicular view. far have spawning of objects correct , y-axis placement correct. need z , x-axis alignment correct. code follows:

void run() {     vector3 pos = transform.position;     quaternion angle = transform.rotation;     gameobject clone;      float startx = pos.x;      pos.y += 0.7f;     pos.z += 2f;      for(int y = 0; y < maxarrows; y++)     {         pos.y += 0.5f;          for(int x = 0; x < maxarrows; x++)         {             pos.x -= 0.5f;              clone = arrowpool.getarrowold();             if(clone != null)             {                 clone.transform.position = pos;                 clone.transform.rotation = angle;                 clone.rigidbody.velocity = clone.transform.forward*force;             }         }          pos.x = startx;     } } 

you're not taking account orientation of player when calculate positions of arrows. work in player's local coordinate space , transform world space.

first choose points in player's local coordinate space.

vector3[] points = {     vector3(-1, 1, 0), // upper-left     vector3(1, 1, 0), // upper-right     vector3(-1, -1, 0), // lower-left     vector3(1, 1, 0), // lower-right     vector3(0, 0, 0) // centre }; 

now need transform these points world space. can using unity's transform::transformpoint function, multiplies passed point transform's localtoworldmatrix:

for (int = 0; < 5; ++i) {     points[i] = transform.transformpoint(points[i]); } 

now have spawn positions arrows in world space.
