Red police Box selection function

Red police box selection function, my idea here is to use unity inside the GL to achieve, and then put the soldiers in a list set, the soldier's coordinates into screen coordinates, and then determine whether in the range of the box, if within the range, move.

(1) Build a material, the color of the material determines the color of the box, and then the type of material is set to Ui/default.

(2) write the following code

usingUnityengine;usingSystem.Collections;/// <summary>///GL Frame, the script must be mounted on the camera./// </summary> Public classcameragl:monobehaviour{ PublicMaterial Mat; Put the first step on top of the material. Public BOOLShoulddrawrect;  PublicVector2 startpos;  PublicFrameselect FS; voidOnpostrender () {if(shoulddrawrect) {Vector2 Endpos=input.mouseposition; Gl.            Pushmatrix (); Mat. SetPass (0); Gl.            Loadpixelmatrix (); Gl. Begin (GL.            QUADS); Gl.            Vertex (startpos); Gl. Vertex (NewVector3 (Startpos.x, Endpos.y,0)); Gl.            Vertex (Endpos); Gl. Vertex (NewVector3 (Endpos.x, Startpos.y,0)); Gl.            End (); Gl.            Popmatrix ();            Fs.selectSoliders.Clear (); foreach(Solider Minchfs.allsoliders) {Vector3 pos=m.transform.position; Vector3 Temppos= Camera.main.WorldToScreenPoint (POS);//turn world coordinates into screen coordinatesVector3 P1 =startpos; Vector3 P2=Endpos; if(Startpos.x <endpos.x) {p1.x=endpos.x; p2.x=startpos.x; }                if(Startpos.y <endpos.y) {p1.y=Endpos.y; P2.y=Startpos.y; }                if(Temppos.x > p2.x && temppos.x < p1.x && temppos.y > P2.y && temppos.y <p1.y) {m.Select=true;                FS.SELECTSOLIDERS.ADD (m); }            }        }    }    voidUpdate () {if(Input.getmousebuttondown (0) ) {Shoulddrawrect=true; Startpos=input.mouseposition; }        if(Input.getmousebuttonup (0) ) {Shoulddrawrect=false; }    }}

3 Code Box selection control

usingUnityengine;usingSystem.Collections;usingSystem.Collections.Generic;usingUnityengine.ui;/// <summary>///Box Selection Control/// </summary> Public classframeselect:monobehaviour{ PublicList<solider>allsoliders;  PublicList<solider>selectsoliders; voidAwake () {selectsoliders=NewList<solider>(); }    voidUpdate () {if(Input.getkeydown (Keycode.escape)) {foreach(Solider Iteminchselectsoliders) {Item.Select=false;        } selectsoliders.clear (); }    }}

4 Soldier Class

usingUnityengine;usingSystem.Collections;/// <summary>///Each soldier mounts the class/// </summary> Public classsolider:monobehaviour{[Serializefield]Private BOOL_select; [Serializefield]Privatecolor color; voidAwake () {_select=false; Color= getcomponent<meshrenderer>(). Material.color; }     Public BOOL Select    {        Set{_select=value; if(_select) {getcomponent<MeshRenderer> (). Material.color =Color.green; }            Else{getcomponent<MeshRenderer> (). Material.color =color; }        }        Get        {            return_select; }    }}

Probably this is the case, the specific project documents, I hit the package at the address below, you can download, I use the Unity version is 5.1.2f, if the version is low will not open, the version of High may have problems
