2D Physics example: Line Of Sight with Chipmunk4PB

[IceSoft]

It will be delivered like the MP3D engine.
A binary release with some demos (also binaries) and with lot of example codes.

That's unfortunate. I was hoping to be able to use this, but I suppose I'll have to put together my own solution.

Sorry I do not understand you. The Chipmunk4PB wrapper is a static libray written in C++ which wrap the whole C function from the Chipmunk physics engine. You can use the wrapped function like an original Chipmunk C function together with PureBasic.

Maybe you have to see some examples first before you be unhappy with my solution.

I'm trying to minimize the number of binary-only things I'm interacting with in my projects. At the moment, that list consists of only the PureBasic compiler. The Chipmunk physics engine itself is open source, so my long-term solution is almost certainly going to be to do my own PB bindings for Chipmunk.

Examples won't address my concerns, I'm afraid.

Yes that is a good idea. One more binding is an improvement for all (Chipmunk and PureBasic).

I'm pretty close to ready to publish my preliminary results with chipmunk 6.x so far. Not just the wrapper itself, but the methodology; it's been a heck of a learning experience.

I haven't tested it for sure yet on platforms aside from x86 windows, but I believe this will be usable on both windows and macOS, 32-bit and 64-bit. It's a mixture of PureBasic and plain C, with a heck of a lot of auto-generated stuff.

And oh, so many mistakes I've made along the way...

But as of this moment in time, I'm successfully getting the simulation going, able to add entities and collision callbacks.. It's hard to measure performance, since my test framework seems to be hitting on graphics performance quirks in PureBasic. (and anyway, the Chipmunk library itself is still compiled debug for now)

Thanks. I am very interest about your result.

If you want to see my posts on my struggles so far, you can find them here (part 1) and here (part 2).

Warning, strong opinions therein. :)

I want to get things to a more polished/validated state before posting anything for people to use, although I do have one of my test applications on dropbox here.

This is an x86 windows binary that does nothing special except put 8000 objects on the screen, and do some 'world wrapping' at screen edges. The circles do collide with each other, though it's hard to tell.

Hello void,
Can I get the PureBassic Source code for comparing the performance between your gcc and my VisualStudio compiler settings?
A PM is also welcome.

Thanks

I suppose so. My current testbed code is pretty hideous, though. I'll send both the .pb and the .pbi code in a PM.

@void,

I have adapt it and it works different.
My chipmunk wrapper creates a border. Your wrapper does it not.
Hope I can send the sources today afternoon.

Got another one? Or will you rebuild it?
