you need to detect all the entities in front of the player

then trace a line betwen the player eye position and where the ray trace vector hits

Vec3 vi = pe.getEyePosition();
Vec3 vo = pe.getLookAngle();//is a delta  
float dist = 6.0F;
Vec3 vh;
vh = new Vec3( (vi.x + (vo.x * dist) ), (vi.y + (vo.y * dist) ), (vi.z + (vo.z * dist) ) );

and check from the entites detected whitch one hitbox touch the line and then gets the closer to the player that one is the one you are looking at 
the code you need is inside the arrow entity you have to extract from it and make your thing
