Thread-safe any_ptr: Is this code actually thread-safe?
|
It's been quite some time since this article has been posted on GameDev, and recently I got to thinking if a thread-safe version was possible without having to use any (platform specific, or library dependent) synchronization mechanism.
I hap... |

Article on simple Serialization for C++
|
In my spare time, I'm writing a Serialization utility for my game engine, and was wondering if an article about it would be of use to someone.
The reader is almost complete (the writer is still in the works); to be released under the MIT license.

STL List question

Hello everyone,
When I remove an element from an STL List, are all iterators (other than the ones related to the removed element) valid?
As far as Google goes, they're supposed to be valid for a List and not necessarily valid for a Vector,... |

Hi,
I'm not sure where to post this, but I'd sent an article (sweet snippet actually) about 1.5 months back, and it never got published, nor have I received any feedback.
I know that you guys receive lots of such articles, but I was just a bit... |

Verlet Physics: Help!

Greeting all,
I've been trying to implement some Verlet physics stuff, as described in the "Advanced Character Physics" article.
The problem I've come across is this:

Physics frequency

Greetings,
I implemented some rigid body physics from the paper Non-convex rigid bodies with stacking (but I didn't implement everything in it such as shock propulsion). At the moment, there are no joints, just a simple rigid body with gravity/use... |

Thread-safe any_ptr: Is this code actually thread-safe?

Neat idea.
You could do a simmilar thing with the RTTI structures, though it might suffer the same issue that Antheus noted:
*** Source Snippet Removed ***
Or you could replace int with a new type based on th... |

Thread-safe any_ptr: Is this code actually thread-safe?

It's not reliably unique. It's perfectly possible for typeid<Foo>() != typeid<Foo>().
It's the same issue as with allocators across DLLs or member function pointer signatures across compilation units and... |

A Type-safe Generic Pointer

Using a typed NULL pointer as a cast error has a side effect. What if the original pointer was NULL? When cast to type how would a user known what the NULL pointer after the cast indicates ie is it a bad cast or was the... |

A Type-safe Generic Pointer

And again: why not just use boost::any to simply store the pointer? ;)If you're using boost::any to store pointers:
* boost::any allocates memory on the heap to store the object (via new/delete). This happens durin... |

A Type-safe Generic Pointer

Few questions
1. Why are you saying that void* is a popular way for generic pointer in C++? AFAIK it is more C way of doing things?Correct me if I'm wrong, but I think void pointers are used in C++ when the... |

Enum Name
|
While I agree that it's a little error prone, the methods mentioned are not without use. There are plenty of cases where string support is required for existing enumerations from libraries. (like some enum from SDL, for example).

Enum Name

Using Daabli, some pseudocode with your example:
#include "Daabli.h"
#include <iostream> // For cout
enum Color
{
Red,
Green,
Blue
};
// String conversion support
Daabli_Begin_Enum( Color )
{
Daabli_Enum( Red )... |

Enum Name

You could try the following two methods (the second evolved from the first):
1.) Specifically for enumerations: Stringizing C++ Enums
2.) A generic approach: Daabli - String conversion support
(See the section "String conversion support", an e... |
