Check to see if an entity can see another

EDIT:A function to see if an entity is in view of another in 3d

Function IsInRadarView(ent1,ent2,radiusx#,radiusy#,range#,fov#)

TFormPoint EntityX(ent2,1),EntityY(ent2,1)+15,EntityZ(ent2,1),0,ent1

		If (Abs(TFormedX())-radiusx)<=((TFormedZ()+1)*fov)
			;if EntityVisible(ent1,ent2)
				Return True
			;else
				;Return False
			;EndIf
		Else
			Return False
		EndIf
	Else
		Return False
	EndIf
