Box2D implmentation

[Paul Cheetham]

Hi there, 

First, great engine, makes things so much easier!

Now, on to my question. Raycasting in fantom, is it possible or is there a way to use the existing box2d in monkey as well as the fantom implementation?

Basically I'm trying to find objects around a central object and apply a force to the points where the ray hits.

Any ideas?

Thanks.

Paul.

I didn't implement Raycasting into the module right now, but with lowlevel Box2D calls it is doable.

The Box2D implementation is just a wrapper to make things more easier for you. Will add Raycasting soon.

Thanks for the swift reply. I'm sure you have higher priorities than raycasting but thanks for thinking about it.

cheers,

Paul.

I will have a look today. If i can implement it fast, the you might get it tonight.

That would be great if you could. Spent some time last night trying to implement existing box2d with the fantom engine box2d. Have to say I struggled quite a bit and didn't really achieve a great deal. :-(

Ok, it will take at least till tommorow. I have raycasting working but I want to give you also the response angle as a normal. Not only the normal of the face you hit. And that kind of math is a mistery for me at the moment.

Ok, got it. Now let me sleep a night over it. I need to wrap this nicely and then I can post an updated Box2D wrapper plus and example.
I have a lot of private stuff going tomorrow so It will be in around 24 hours too.

Hey, the fact that you have made time to do this is great.

Take all the time you need, it is very appreciated.

Oh, and the math, normals and such like. I'm not sure where I would start with that. Luckily there are people like you out there willing to give us folk a helping hand!!

Sorry Paul that it took so long, but I have now finally uploaded 1.52 which supports easy raycasting.
