Please help me

Thanks in advance

bodyDef.userData = (__bridge void *)physicalView;

UIView *oneView = (__bridge UIView*)b -> GetUserData();

http://www.box2d.org/forum/viewtopic.php?f=7&t=7812

“UIView *oneView = (UIView *)b->GetUserData();” -> error
“bodyDef.userData = physicalView;” -> error

Thanks

A tutorial on how to make the bodies drag-gable will be very useful.

We’re all looking up to you.

I know you can do it! lol

Thank you once again for a great tutorial.

If you solved it, please let me know how. Thanks.

world = new b2World(gravity); // just tested and work fine for the newly v2.21 release

2) then, delete this line too.

bool doSleep = true; // because you don’t need this line anymore.

remark: I tested in XCode 3.25

I am new to IPhone programming but I know Box2D from Flash-Programming and would like to use that.
I have problems to find the “Header Search Paths” to change to ${PROJECT_DIR}.
Where is that – maybe it changed in XCode 4.2? Can’t find it.

I am also not quite sure about:
“Since the default project probably has an include of the our view controller’s header in the app delegate, you need to make the same adjustment for the app delegate’s .m file. Get Info on the those files and change the file type to “sourcecode.cpp.objcpp”.
So I have to change the file type of my ViewController (.m + .h?) and and of the AppDelegate (.m+.h) Cocoa Files? Nothing to be changed in the Box2D files, right?

Cheers,

Oliver

How did you get it to work with dragging the UIViews? I tried it, but the dragging is buggy and when released it just shows up instantly back to where it was.

Please help out if you can.

I’m getting the same and I don’t understand what you mean by “I just used ‘tags’ instead of the ‘Trunk’…”

Please explain it to me if you can. Thanks.

“The Project path must not contain any whitespace”
That’s all

How can i move the UIView objects with my finger ?
Do I need to implement touch methods ?

ex)
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

If the objects in the Box2D world can be moved by implementing the specific method of ‘Box2D’,
Please give the sample code. I hope that it’s going to be fine with adding a few code to Your Good Tutrial.

Thanks a lot.

> I can’t ‘world = new b2World(gravity, doSleep);’. The error is

I just used ‘tags’ instead of the ‘Trunk’…

Thanks.

I’ve just tried to make my Proj. with your post with xcode4, but i got some errors in createPhysicsWorld().

I can’t ‘world = new b2World(gravity, doSleep);’. The error is

/Users/myName/Documents/iOS/[S]ampleProg./Box2d/MyBox2dTest/MyBox2dTest/MyBox2dTestViewController.m:34: error: no matching function for call to ‘b2World::b2World(b2Vec2&, bool&)’

I set ${PROJECT_DIR} as ‘The Header Search Path’ , though…..

Any advice ?
