Camera.ViewportPointToRay

Unity Engine
1

hi!,i try to do a mouseclick walking for my pg,now two question…

i use Camera.ViewportPointToRay?

ok if yes,when i have found my point in 3d space,how can i say to my pg,go in that point?raycast?

what is the script or command i study for that? tnx!

2

anyone? ok,what command for mousex or mousey position?

for this…

var ray = camera.ViewportPointToRay (Vector3(MouseX,MouseY,0));

look for MouseX and MouseY…what is the right command please…

3

tnx,i found this…

Input.GetAxis (“Mouse X”);

is right?

4

this was a bit confusing for me. there an example of how to get the mouse positions and the screentoray function there.

5

TNX!!!only you respond me tnx very much!!! :smile:

6

ok i try this today,but for me when i click the button,generate a particle in 2d!i want transform the position of my click in 3d space…are complex i know…but tnx!

7

ok now i have my ray in space and if i click and found a collider he said me hit!and create a primitive,but the primitive i create at center of space,how can i say,create my Cube in the impact point of the ray?

this is the code…

var waypoint2 : GameObject;

function Update () {
if (Input.GetButtonDown(“Fire1”)){
var ray = camera.main.ScreenPointToRay (Input.mousePosition);
}
if (Physics.Raycast (ray, 1000)) {
print (“Hit something”);
waypoint2 = GameObject.CreatePrimitive(PrimitiveType.Cube);

}

Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);

}

i have solved,but now,when my player arrive at hit point,continue along the way…where is the error? please respond me…i love this community,but not response…please help me… :cry:

this is the code…

var speed : float;

function Update () {
if (Input.GetButtonDown("Fire1")){
    var ray = camera.main.ScreenPointToRay (Input.mousePosition);
	var hit : RaycastHit;
	if (Physics.Raycast (ray, hit,1000)) {
	var target : Vector3 = hit.point;
	var moveDirection : Vector3 = target - gameObject.Find("Personaggio").transform.position;
	var velocity = gameObject.Find("Personaggio").rigidbody.velocity;
	if(moveDirection.magnitude < 1.0){
	velocity = Vector3.zero;
	}
	else{
	velocity = moveDirection.normalized * speed;

	gameObject.Find("Personaggio").rigidbody.velocity = velocity;
	
		}
	}	
}
	
Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);
