From Unity to Babylon

[steffenk]

Hi everyone,

 

iam using Unity for a long time and im realy fine with it. But for my new project i choosed Babylon (because it works in mobile browsers ).

 

For the last weeks i read in the documentation and did some tutorials. But something is still a little unclear to me and the reason might be iam thinking to much in a unity way.

 

Her're some cases i just dont get:

 

User Interfaces - schould i just use html elements overlapping the canvas or is there a more 'elegent' way?

 

Inputs - Unity provides the huge Input class which abstracts keyboard events, controller inputs,  tochinputs and all the nice stuff which prevents me for reinventing the wheel all the time . whats best practice in Babylon?

 

Deltatime - usualy , when i do timerelevant stuff, i'm accustomed to use deltatime (the time passing between 2 frames) but i couldnt find something simular in Babylon

 

Constrains/locking movement - for example how can i preserve a physicaly obejct for rotation arround its Y-axis

 

thnaks for your answers

 

edit: is there any kind of 'whole project workshop' out there? Most tutorials, i found,  a very short and breaty beginnerish ^^

Hey there, 

 

User interface, you can use native HTML/CSS, or a custom extensions like bGUI or castorGUI (https://github.com/BabylonJS/Extensions)

Inputs : I'm not aware of any extensions for this.

Deltatime : you can use engine.getDeltaTime() https://github.com/BabylonJS/Babylon.js/blob/master/src/babylon.engine.js#L1891

Constraints: I'm not sure about this but I don't think something like this exists.

Tutorials: you can find a lot of tutorials in the doc (http://doc.babylonjs.com/) or on my website (http://pixelcodr.com/)

 

Good luck

ANd don't forget about the Unity Exporter:

Temechon, your tutorials are fantastic

 

In your last physics tutorial (http://pixelcodr.com/tutos/physics/physics.html) how would you preserve the green cube to rotate around the Y axis when it hits the wall not exatly straight?

Hi gang.  I've been looking-at http://www.zebkit.com/  Zebra Canvas-based GUI thing.  Smells kind of good.    Maybe I could use it to make this fake dashboard... into a REAL one...  http://playground.babylonjs.com/#1VXHZA

Maybe import Zebra into a playground with the Jerome Maneuver...

http://playground.babylonjs.com/#1VXHZA#5

...and start playing.    The bottom area is now a canvas and Zebra is on-board.

@Wingy:

 

Another couple of interesting demos. I just wish that all of these demos could be found in one place - there must be over a hundred by now that are scattered everywhere.

 

I'm no great coder - so I learn by looking at the code created by others.-then hacking it Learning by example? And you provide a lot of examples - but they can be hard to find.

 

Sorry, don't want to hack this thread- just wanted to comment on your efforts.

 

cheers, gryff

I second what gryff said. Could we have a list of all demos ever made? That would be awesome. Hours of fun clicking trough all of them and seeing what funky stuff people did there

Why not add a new page in the documentation ?

RE: Master playgrounds list... let's head over to Tutorial Talk, guys .  This Unity-to-Babylon subject is pretty fresh and important.

[steffenk]

Thanks for hijacking my thread, guys

@Temechon: how would you avoid the green cube, in your last physics tutorial, rotating arround its vertical axis?

[Temechon]

Steffenk, I don't know at all. I looked for it in Oimo but it doesn't seem to have axis constraint like you need.

I add this development to my backlog
