I'm looking for an example of how to implement 2D terrain destruction that you see in games like scorched earth or on the iphone iShoot .
I'm looking to implement a game that needs to do destructible terrain and render it using OpenGL (LWJGL in Java) ...

If you actually want the terrain to collapse like it did in Tank Wars, you'll need... .
Hit detection is always done on the mask.
As I recall, in Worms they used two images; The "pretty" terrain with colour, and a mask terrain that is pure black and white .

Does ISO C++ standard mandate any sort of destruction order of objects inside STL containers?
Are std::list / std::vector / std::map elements destroyed starting from the beginning or the end of the container? Can I rely on std::map storing its elements...

Yes, but this means ....
Unspecified in the standard.
Unspecified Yes, you can depend on std::map storing it's elements in std::pairs, but I don't see anything which specifies the Key portion of a std::pair being destructed before a Value portion.

Scenario is that I am subclassing a dialog and application can launch many instances of that dialog.
Is it necessary to add unsubclassing code to all the dialogs in thier destruction...

If you're using instance subclassing (SetWindowLongPtr), then since when....
Though be aware that if you've any resources you're managing manually, you must have tidied them up in the WM_CLOSE message .
Assuming you're talking straight Win32 API, then yes.

Does InputStreams and OutputStreams in Java close() on destruction? I fully understand that this may be bad form (esp in C and C++ world), but I'm curious.
Also, suppose I have the following code:
private void foo() { final string file = "bar.txt"; Properties...

There's only the Garbage Collector, which.
There's no such thing as "destruction" (in the C++ sense) in Java.

Hi, is the following code safe (it works in DEBUG) :
void takesPointer(const Type* v);//this function does read from v, it doesn't alter v in any way Type getValue(); ... takesPointer(&getValue());//gives warning while compiling "not an lvalue" ... Type...

And no, the optimzier can't destruct the result of getValue() before calling.
It to a const pointer lvalue.

It's been at least 5 years since I worked with Java, and back then, any time you wanted to allocate an object that needed cleaning up (e.g. sockets, DB handles), you had to remember to add a finally block and call the cleanup method in there.
By contrast...

Deterministic destruction hasn't been implemented in Java and .NET, by the way - it tends to involve reference.

I’m trying to create a simple Win32 DLL. As interface between DLL and EXE I use C functions, but inside of DLL i use C++ singleton object. Following is an example of my DLL implementation:
// MyDLLInterface.cpp file
#include "stdafx.h" #include <memory...

Is it possible to force.
It looks like the destruction off MySingleton happens after EXEs exit.

I have made the following little Program: (basically a class that couts if it gets created, copied or destroyed and a main that does some of that)
class Foo { public: Foo(string name): _name(name) { cout << "Instance " << _name << " ...

Try adding this function to Foo:
Foo& operator = (const Foo& rval) { cout << _name << " = " <&... .
At that point one of the "albert" instances becomes "bert" .
When you do v1 = v2 that operator is used .
There is an auto generated = operator.

Can I control the order static objects are being destructed? Is there any way to enforce my desired order? For example to specify in some way that I would like a certain object to be destroyed last, or at least after another static onject?

Answer Snippets (Read the full thread at stackoverflow):
You can always use a singleton to control the order of construction/destruction of your global in a single translation-unit the initialization....
You should never rely on the other of construction/destruction of static objects.
No, you can't.

I have 2 static objects in 2 different dlls :
An object Resources (which is a singleton), and an object User . Object User in its destructor has to access object Resources.
How can I force object Resources not to be destructed before object User?

But this one.
I don't think you can change order of destruction of globals a new issue: global variable destruction order is not garanteed by the c++ language.
Code in destructors.
