Raycast from one mesh to another one

[rgalindox]

Hi, I'm trying to create a ray from one mesh to another one, but I have problems with the direction.

I'm using this one:

var ray = new BABYLON.Ray();

var rayHelper = new BABYLON.RayHelper(ray);

 

var localMeshDirection = new BABYLON.Vector3(-1, 0,0);

var localMeshOrigin = new BABYLON.Vector3(0, 0, 0);

var length = 20;

 

var door = scene.getMeshByName("shop08");

rayHelper.attachToMesh(door, localMeshDirection, localMeshOrigin, length);

rayHelper.show(scene);

 

In the above case I have a ray on the -x axis, but I need to use the direction of a specific mesh, basically when the user click on any mesh the ray will check for collisions in between. 

 

How can I get the direction of a specific mesh and include it on the rayHelper.attachToMesh ?

 

Thanks for your valuable help.

Hi, I figured out  :

 

now I need to see the collision

function myRay(){

var door = scene.getMeshByName("mesh1");

var punti= scene.getMeshByName("mesh2");

var origin = door.position;

    

var forward = punti.position;       

 

var direction = forward.subtract(origin);

direction = BABYLON.Vector3.Normalize(direction);

 

var length = 20;

 

var ray = new BABYLON.Ray(origin, direction, length);

 

let rayHelper = new BABYLON.RayHelper(ray);     

rayHelper.show(scene);  

}
