X-ray collision test sharing in Unity:

Physics.raycast: Ray projection

Parameters:

Origin: Ray start point

direction: Ray Direction

Distance: Ray length

Layermask: only The collider within the Layermask layer is selected, and the other in-layer collider is ignored.

Returns

Bool-true when the ray intersects any collider,otherwise false.

True if Ray casts intersect with any collider, otherwise false.

Here's a small example to experiment with: Click where you want to move

usingUnityengine;
usingSystem.Collections;

Public classCapsule:Monobehaviour {

     Public Charactercontrollercc;
     Public floatSpeed ;
     Public Cameracamera;
     Public Vector3targetposition;
    voidStart () {
targetposition= This. transform.position; // Assign the initial position to the current coordinates
cc= This.gameobject.getcomponent<Charactercontroller> ();
    }
To define a ray method:
    voidGethitpoint () {
        RayRay; // Create a new Ray ,
        RaycasthitHit ; // Ray casting clash Qi
        if(Input. Getmousebuttondown (0)){ // If I click on the screen to trigger the Ray
Ray=camera. Screenpointtoray (Input. mouseposition); // screen position turn Ray
            if(Physics. Raycast (Ray, outHit , -)){// Ray projection -- true when Ray casts intersect with any collider , the Ray Distance
//Debug.Log (hit.point);
                if(hit.collider.gameobject.name=="Terrain"){
Targetposition=hit.point;
                    //debug.log (targetposition);
                }
            }
        }
    }
    voidWalk () {
        Vector3v=Vector3. Normalize (targetposition- This. transform.position);
cc. Simplemove (v*speed* Time. deltatime);//simple Move method.
    }

    voidUpdate () {
//Vector3 v=new Vector3 (0,0,10*speed*time.deltatime);
if (Input.getkey (Keycode.a)) {
Cc. Simplemove (v);
//        }
walk ();
gethitpoint ();
    }
}
