Create a particles helper library

[deltakosh]

Something like createFire or createSmoke

I can do that.
/src/Helpers is this the right place for that?
I will start this very soon.

I'm open for more create methods like that :)

[deltakosh]

The idea is to create one-liner for smoke, fire, etc...
I think we can have it in helpers folder with a static class named ParticleHelper or something along this line
Assets should default to ressources saved to assets.babylonjs.com (which is mapped to the /assets folder)
The idea is not to have particles setup hard written in the helper.
I suggest to set up a folder in /assets named particles where particles textures and a json file describing each setup should be

The json file could describe all parameters of each particle setup

From a user standpoint, I see it like that:

var system = ParticleHelper.Create("fire", true);

The first parameter will look for a configuration named fire in the central json. The second one indicates that I want a GPU system (if the configuration allows it)

I hope this makes sense:)
Thanks a lot for your appreciated help!

Ok, nice, but the third argument for the ParticleSystem constructor is the Scene, so, Is there a way to get the scene, or we have to pass it to the main create() method too?

[deltakosh]

Right:) we need a third one (optional as Engine.LastCreatedScene can be used)

[yovanoc]

Great, I'll make a first try. Then we can discuss around that

[deltakosh]

Wonderful!!

Also, how can I correctly read a .json file in the /assets/particles folder, knowing that it becomes the domain name you told me?

For now, I've already put that for basic textures that I will use but can I use it for the json file properly?

private static _baseAssetsUrl = "https://assets.babylonjs.com/particles/";

[deltakosh]

This is fine!

[yovanoc]

Where do you want I add a unit test for that?

[deltakosh]

in /tests/unit please :)

[yovanoc]

Yeah, of course, but i add a new file?

[deltakosh]

Sure thing!

[yovanoc]

But why there are no scripts in package.json to run tests? how do I launch these tests so?

[deltakosh]

just go to /tools/gulp and run gulp tests-unit
