Managing pointers in cpp target about haxebullet

[Ohmnivore]

At this point I'm thinking either hxcpp manages pointers automatically, or if it doesn't maybe this will help: http://api.haxe.org/cpp/vm/Gc.html#setFinalizer

There's maybe other ways to do this, but this is the most obvious one to me:

#if js
typedef BTDiscreteDynamicsWorld = BtDiscreteDynamicsWorld;
#elseif cpp
typedef BTDiscreteDynamicsWorld = Pointer<BtDiscreteDynamicsWorld>;
#end

JS's create() and CPP's create() would both return a BTDiscreteDynamicsWorld, and in the user's classes fields would be defined as BTDiscreteDynamicsWorld too. Unless I'm overlooking something this would allow us to treat instances exactly the same in both targets, granted we're calling .value() first.

BTDiscreteDynamicsWorld instead of BtDiscreteDynamicsWorld is just an example, we would need a much more different typedef naming scheme to avoid confusion.

[Ohmnivore]

Even better:

typedef BulletDiscreteDynamicsWorld = 
#if js
BtDiscreteDynamicsWorld;
#elseif cpp
Pointer<BtDiscreteDynamicsWorld>;
#end

[Ohmnivore]

Betterer?

typedef BulletDiscreteDynamicsWorld = 
#if cpp
Pointer<
#end
BtDiscreteDynamicsWorld
#if cpp
>
#end
;

[Ohmnivore]

Hmm only way that stays fully compatible with FlashDevelop's autocomplete is

#if cpp
typedef BulletDiscreteDynamicsWorld = Pointer<BtDiscreteDynamicsWorld>;
#end
#if js
typedef BulletDiscreteDynamicsWorld = BtDiscreteDynamicsWorld;
#end

for (i in 0...9000) {ctrlc();ctrlv();};

Hey,

Is it not the same like the thing already included?

I went with 'Pointer' indication but it is easy to use your own typedefs as you do.

Ammo.js used to require calling destroy() too, but not sure if that is still the case. Ideally we get rid of that if possible:)

[Ohmnivore]

Oops. Didn't realize you had typedefs already.

I honestly have no idea what the .destroy() usage should be on cpp/js, i guess i'll figure it out when i find memory leaks.

Cleaning up, if someone needs to take care of .destroy() usage urgently feel free to open another issue.
