Checking collisions of the camera with the imported scene

[Dimitry]

Hello!

There is a small scene imported from 3dsmax: http://sitesman.com/3dcity/1/

There is a free camera there, what I am trying to achieve now is to disallow the camera to walk through the walls and objects. 

 

So the code goes like this: 

 

Scene.gravity = new BABYLON.Vector3(0, -9.81, 0);   Scene.collisionsEnabled = true;camera.checkCollisions = true;camera.applyGravity = true;camera.ellipsoid = new BABYLON.Vector3(1, 1, 1);Scene.checkCollisions = true;

Well and as you can see the camera goes through the walls. I feel something else should be done here, maybe I should create invisible meshes like squares and put them around the walls? Or what is the fastest method. Thanks!

Hi,

 

 Nice scene. You need also to create some colliders and enable the collisions on them for that. Most of the time, we're using invisble box/meshes colliders. You can read my article to have a better understanding of what you need to do: http://blogs.msdn.com/b/davrous/archive/2014/11/18/understanding-collisions-amp-physics-by-building-a-cool-webgl-babylon-js-demo-with-oimo-js.aspx

 

 Basically, in 3DS Max:

 

 - create some boxes to match the various areas of your scene

 - make them invisible

 - enable collisions on them

 

Bye,

Thanks David! My instincts were right then :-)
