Tag Issue

[freetoplay]

Hi, I am getting an error when I try to loop through checking for tags.

In my code, I have:

 let oldMesh = scene.meshes;
                    for (let i=1; i < oldMesh.length; i++) {
                        BABYLON.Tags.EnableFor(oldMesh[i]);
                    }
                    oldMesh[3].addTags("test");

Inside my importMesh function, I have:

BABYLON.SceneLoader.ImportMesh(null, "/assets/", "test.glb", scene, function (meshes, particleSystems, skeletons) {
                       meshes[0].position.y += 1;

                        for (let i=1; i < oldMesh.length; i++) {
                            console.log(oldMesh[i]); // this works fine
                            console.log(oldMesh[i].hasTags()); // this throws an error
                        }
               
                   });

 

Does anyone know know why the hasTags function is throwing an error in the loop?

Hi FTP.  Sorry to hear you are having problems.  Could you build a playground demo... that reproduces the error?  That would be great.

Also, it might help to tell us WHAT error was seen.  thx.

oldMesh refers to scene.meshes so will change during import and you are not enabling tag again on the new elements.

You need to create a new list if you want to keep track of some of them.
