sloved Raycast - bug or not ?

[hulahula]

Hello

I found one bug I think. In this exampel https://www.babylonjs-playground.com/#KNE0O#4

I found this example o https://doc.babylonjs.com/babylon101/raycasts

ray.show(scene, new BABYLON.Color3(1, 1, 0.1));

When I tried this code, which was prepared in exampel then babylon.js stop worked.

Sorry for my poor english.

You must use a RayHelper now. I had reported it a long time ago, and this has never been corrected (Or it was forgotten). I will send the fix.

let rayHelper = new BABYLON.RayHelper(ray);       
rayHelper.show(scene);

@Dad72  I have one question for you 

I am making littel  "Space-RPG"  and question is : Can I   make  2 imported obj  in ma game like  for exampel player and door intersect with raycast (raycast is a part of the player )  if  i using this mathod : 

  if (rayCast.intersectsMesh(door, true)) {

    console.log("open");

  } else {

    console.log("closed");

  }

   I have littel problem whit it ? it  doesn't register intersection 

[Dad72]

IntersectMesh is for meshes that detects another one. Your code here will not work, I think.

You have to do something like

if (character.intersectsMesh(door, true)) {

    console.log("open");

  } else {

    console.log("closed");

  }

I understend @Dad72.. so raycast  can´t  pick only  specific  obj ? for exampel : only doors in  room with lot of other obj in it

[Dad72]

If you use RayCast you do not need IntersectMesh :

Your ray code ...

var hit = scene.pickWithRay(ray);

if (hit.pickedMesh){
       
      var mesh = hit.pickedMesh;

       console.log("open the door");

}

 

[Dad72]

You can also do in the condition

if (hit.pickedMesh.name == "door"){

console.log("open the door");

} else {

console.log("close the door");

}
