List of loaders for RUBE scenes

[gOzaru]

Is rube can be implemented in Unity 5?
It is using C#.

[iforce2d]

What do you mean when you say "implement"? I think unity has its own 2d physics engine doesn't it?
In any case, if Unity can read in a .json file and do something useful with it, then I guess you could 'implement' something...

[gOzaru]

you are right.
I just found out about it.
it is called polygon collider 2D, rigid body 2D.
thank you.

I just wanted to share a simple loader. The UserData is just inherited from Dictionary<string,object> with no modifications (yet).

The RUBE Loader for Phaser Box2D doesn't seem to work when the simulation is compiled from Typescript. Is there any chance of getting Typescript support for RUBE Loader?

Let just me google "typescript"....
If you could be more descriptive than "doesn't work" you might find more help from others who know about it.

The Box2D plugin for Phaser just fails silently after I link the phaser-rube.min.js in my HTML file, even without any attempt to load a RUBE scene. If I remove phaser-rube.min.js, the game loads fine. My main.js file is compiled from Typescript into Javascript. I'm guessing it's a namespacing issue.

Code: Select all

<script src="js/phaser.2.4.7.min.js"></script>
<script src="js/box2d-plugin-full.min.js"></script>
<script src="js/phaser-rube.min.js"></script>

I'm having a similar issue with Phaser 2.4.7 and 2.4.8.
I created a thread in the "Bug reports" board you may want to follow.
