Move imported mesh

Questions
1

Hello.

When working on my game I have the fov of the camera zoomed in to “aim” the weapon. I also need to move the weapon in order to aim down iron sights. I have the weapon and the arms as a single .babylon file, and I have them as a child to a transform node. I am not able to change the position of the transform node after the model loads. It worked ONCE, but I changed the position of the transform node at the start and it stopped working. any help would be great.

Thanks, Givo.

PS: I am asking for help so much on these forums, I’m gonna credit the top 5 people who have helped me!:smiley:

We need a repro in the PG to help (as usual :))

I’ll try, but the playground doesn’t like my gitlab hosted models. Here is the link to the model: viewmodeltest.babylon

Check out my website giv0.gitlab.io/fpsg. The viewmodel looks good! Right click to “aim”!

Well here is a doc for that:Using External Assets - Babylon.js Documentation
It is clearly easier to help you if you can repro in the playground

5

I didn’t know about that. I’ll make the playground now :slight_smile:

Here

I followed the steps but it didn’t show up :frowning:

Well this link seems not to work

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmm…

could you try to modify the link? It was in my second post.

Not sure to get what you want me to do :smiley:

In your second post, you had the link to the using external assets page. In MY second post, i had the model’s link. I modified it and you showed that it didn’t work. I was wondering if you could try to change the link to work in the playground. I’ll try again, though.

11

wait a minute. it uses gitHUB. I use gitLAB. I wonder if that has something to do with it not working.

12

ok :slight_smile:

I don’t know for gitlab to be honest. But if your problem is not related to the mesh directly maybe you can just recreate your problem with spheres and boxes

13

I can’t recreate it. The sphere works fine. I had it working ONCE but then I changed the value of the position and it stopped working.

I use gitlab because I like it’s web ide.

14

ok so repro is mandatory :smiley:

15

Yes, I would say so too.

16

I could use the “dude” model to recreate it.

17

good idea

TA DAA

Here it is! On right click, the camera zooms in. Dude should move down. he doesn’t. YAY a repro!

wait… why am I happy about an issue?

Hi @Givo You’re declaring " vmtp " inside the sceneloader success callback, but try to access/change it on pointer down/up (out of scope).

you should instead do something like this:

var vmtp;
BABYLON.SceneLoader.ImportMesh("him", "/scenes/Dude/", "Dude.babylon", scene, function(newMeshes) {
    vmtp = new BABYLON.TransformNode();

Oh. I tried moving it outside, but not like that. I’ll try it. thanks!
