Raycast from one mesh to another one

Recommended Posts

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);  
}
