CreateGroundFromHeightMap and getHeightAtCoordinates

[destroyer]

Hi,

 

I created a ground using:

 

var ground = BABYLON.Mesh.CreateGroundFromHeightMap("", "textures/heightmap.png", 1000, 1000, 250, 0, 10, scene, false);

 

And created my player, which is a Box/Cube:

 

var player = BABYLON.Mesh.CreateBox("Box", 1.0, scene);

 

Now, I want to detect the collision between them.

 

However, when I call this function: 

 

ground.getHeightAtCoordinates(player.position.x, player.position.z);

 

I receive this error:

 

Uncaught TypeError: Cannot read property 'boundingBox' of undefined

 

Could somebody help me to solve this issue?

 

Thanks.

Hello and welcome!

 

To help you we need to be able to see it live

 

could you use www.babylonjs.com/playground to reproduce your bug?

Deltakosh, I separated the minimal necessary to run on your machine, please try the attached.

I couldn't run it on the babylonjs playground since I have a heightmap image to load.

 

Thanks in advance.

Delta, 

 

I reproduced the bug, please look:

Why can't I retrieve the Height?

 

Thanks!

Delta, I solved!

 

I checked the source and I noticed that I had to call: ground.refreshBoundingInfo(); before trying to retrieve the Height.

 

Is this right? Shouldn't it be called automatically at the instanciation?

 

Thanks

You're right. This is because refreshBoundingInfo() is called automatically during rendering process. Here you're trying to retrieve height before, this is why
