Movement Extension:Physics Platform Movement?

[Iwantmyrpg]

Since I recently got into a physics class, and a calculus class. I've been really itching to make a physics engine that works without glitches.
Something that's actually simple to use like the platform movement, except based on those real formulas of physics. I was thinking of making a movement extension that would almost mimic platform movement, except mass and forces would be accounted for. Or an extension that would automatically move objects by hand. But mass manipulation is a little difficult, and im thinking of making the extension easier than the chipmunks engine.
So I'm looking for a little help as to how a movement extension works/is coded.

I've also seen the Phyizix-Box2D extension at work, but I don't know how to use it. I'm thinking of something a little simpler which works well with MMF2's built-in collision dectection with backdrops and actives (the ones used for the platform movement), but realistic as possible in comparision to Phyizix-Box2D.

In addition to what I've said above, I'd like to know how to make those properties tabs. They'd be extremely useful so I wouldn't have to make conditions and actions to set every single thing while in runtime.

Great! I think one of the main reasons people have problems with the extensions is the lack of documentation for applying the events in real world scenarios. Lack of Help documentation and examples can be the difference between an extension being used properly or completely improperly or not at all :blush: .

I think there was some movement help/examples with the standard SDK but not for rSDK though. I definitely think more extension development tutorials/docs would be good articles for wiki though.

For learning box2d there is the main examples but also as it's based on the regular engine you could maybe try the main site -

http://www.box2d.org

There is a forum and manual etc but there is of course no MMF2 help. If you look at any code snippets or the manual you can get the general idea how to do the same thing with the MMF2 version though so i am sure it would help with that.

Alright thanks, I'll go ahead and try to find the SDK and those examples. I guess I'll have to stick with the examples cause I got an error with the help file included. "Navigation to the webpage was cancelled" That was unhelpful. This will take one heck of a while .

The links are on the left of the main Box2D page. I don't know what help docs you are looking at, you only really need the links that can be found directly from the main site though. But remember that is for the main Box2D engine and not for the MMF2 version, it would only help with Box2D and general concepts also so if you are doing a physics course anyway that might be better.

For building a actual MMF2 physics extension though there is not that much info available for this type of thing really. The best resource would be the help document that is included with the main MMF2 SDK.

I was refering to the help document included with the SDK. Thats the error I get. Is there a way to uncompress the html and view it as an actual file in IE? That seems to me like the only solution.

Oh ok, well it is a .chm help but I don't know of any conversion tools though but i am guessing there would be some.

I am guessing this was made a long time ago now so it could well be that any website links it has no longer work. If you mean just viewing it then it works fine here so i am not sure how to fix that if it doesn't open.

I can open it, its just every page I open has that error. If it works on yours can you make some form of copy in a file other than .chm? Like .txt or a word file? I'd appreciate it, cause I'm completely lost as to how the SDK works, I figured it'd be similar to the rSDK but I can't see the resemblance.
