Rube Importer

toojee

Hi,

there is a chance to have somewhere a Rube importer in Citrus Engine?
https://www.iforce2d.net/rube/

Or a tutorial to do that?

Hey, Rube is really great for working with Box2D. However nothing is planned at the moment on my side.
As a paid third party tool, it isn't my priority.

I know it exports a scene into a json file. Taking a look on the ObjectMaakers you should be able to write your own!

Good luck!

Hi! I already started to code an importer to Citrus.
I can create body with multiple fixtures, circle etc...

But I have some issue like box2dflash not include rope, wheel and motor join, so it's gonna be incomplete...

I have another issue with bodies which sink into Citrus Platform, and I don't know why for the moment. I look around filters but even with default properties, same problem happen. And some bodies move through platform directly.

I create few class for citrus engine rube importer. You can find these here:
https://github.com/toojee/Citrus-Engine-RUBE/

For some reason I don't be able to upload all my folder like /bin et /obj...

You can import bodies with multiple fixture, circle, polygons etc...
You can import 5 types of joint revolute, distance, prismatic, weld, friction.

But I have a problem of upside down objects... I can't figured out what I have to do to change that.
If you do in ObjectMakerStarling2.as:
vVertices.push( new b2Vec2( aVerticesX[i], -aVerticesY[i] ) );
in place of
vVertices.push( new b2Vec2( aVerticesX[i], aVerticesY[i] ) );

(just - of vertices y)
It's look great but collision don't work...

Ok I find solution for my problem.
Now everything look right.

Next update, I will use custom properties to create Citrus Class like Hero, platform, sensor etc... with RUBE.

Great works!

Very exciting. I have been building complex objects in PhysicsEditor and trying to get them into Citrus and it doesn't work very well 🙂 Particularly skinning and getting things to rotate around a certain center point. So looking forward to this becuase I quite enjoyed using RUBE but there was no way to get it into citrus.

Please keep us updated!

Thx Aymeric and cynicmusic!
I try PhysicsEditor, but its pretty incomplete! My goal is to create the entire physic level with rube.

I have updated my github : https://github.com/toojee/Citrus-Engine-RUBE/
I take citrus braid example for the graphic assets.

Changes:

Creation auto of CitrusClass and CustomClass with custom properties in rube
Configuration of box2d world directly in rube

Issues:

the BraidHero have issue when run in slope (not Hero class)
when the hero jump, he moves left or right too fast
when hero jump next to platform : http://imageshack.us/photo/my-images/827/braidstuck.jpg/

I think issues are due to my unfamiliarity of box2d. Right now, I don't have any basis on friction, linear velocity, density and stuff like that.

But look at the rube file, you'll see rube importer works!
