Issue with Ammo?

Questions
1

Hi! I transformed a cart game but failed to embed it using the attached code. Am I missing something in the html portion? I suspect there is something that it didn’t like with the Ammo.js.

FYI, The portion from /******* Add the create scene function / to /* End of the create scene function ******/ loads fine inside Babylon.js.

Thanks

So what is the problem you are having ???

I get a blank screen. I want to upload the entire code here, so you can take a look at it in detail. But how?

Try uploading your source to Github and then post the link here.

Here it is! Any ideas why it would give me a blank white screen would be much appreciated. Thanks everyone.

I’m not sure if you checked the console at all, but there are a couple of issues.

  • You made your createScene async so at the end where you call var scene = createScene() you’re actually defining scene as a Promise. So you actually have to do this:
		createScene().then(scene => {
			// Register a render loop to repeatedly render the scene
			engine.runRenderLoop(function () {
				scene.render();
			});

			// Watch for browser/canvas resize events
			window.addEventListener("resize", function () {
				engine.resize();
			});
		});
  • keydown and keyup are not defined when you are adding the window event listeners, either define those functions or remove those lines.

After those are fixed it renders.

Sorry to bother you again, but I have another example that has a similar situation. The screen is blank. Maybe you can take a quick look. The code is copied from one of BabylonJS examples:

What’s the error in the console?

When I load it in jsfiddle, I get a blank white screen.

JSFiddle should still have console errors, from what I can tell it looks like something to do with the GUI instantiation which I’m not terribly familiar with.

You are absolutely correct. I deleted the dat.gui part and it loads okay. Thanks for the clue!
