I am programming a small game for my school assignment, the game is a simple 2D game with monsters, items and bullets. Basically you run around and tries to collect all the item coins, the monsters tries to prevent you and you can shoot them down with the bullets that you collect. Very simple. The question is, i have added the monsters,...

What I want to do is change the baseclass so that it works like class AutoComplete(PriceCtrl): .....

I'm always tempted to extend the Sprite class just so my object can be part of the display list (and also have EventDispatcher functions), even though it has nothing to display. It will, however, contain things to be displayed. It's convenient because those contained objects need only reference their container for display list access. H...
For example, suppose I do this: >>> class foo(object): ... pass ... >>> class bar(foo): ... pass ... >>> some_dict = { foo : 'foo', ... bar : 'bar'} >>> >>> some_dict[bar] 'bar' >>> some_dict[foo] 'foo' >>> hash(bar) 165007700 >>> id(bar) 165007700 Based on that, it looks like the class is getting hashed as its id number. T...
Recently I was asked in an interview that, can an Interface be considered as a class in C#? I.e. is an interface is a class in C#? I was confused. What can be the answer? ...
I am trying to derive a class from a python primitive, the float, for the purpose of printing a different repr string when it's printed out. How do I access the underlying data from the derived class when I do this? Here's a simplified example of what I am trying to do: class efloat(float): def __repr__(self): return "here...
I'm using the Prototype.js (from www.prototypejs.org) library to create classes which are extended by subclasses. I'm having trouble using arrays within instances of these classes though. I've made an example to illustrate this: var SuperClass = Class.create({ initialize: function(id) { this.id = id; } }); var SubClass = C...
Hi, my questions pertain to class objects defined for mysql/php interface: Which of the following method is best from a design point and why (relative advantages/disadvantages to each other): To use a single class like ezSQL towards abstracting the mysql/php interface? To use a combination of a DB Connection Class and a Results Class...
I'm working on learning the basics of AS3 and have been working through a tutorial book. We just made a class that, when linked to movie clips (or conceivably any sprite) would enlarge them when rolling the mouse over them. To make sure I remembered all the principles, I tried to make a class that would make the sprite spin when moused...
How do you access Library items from classes other than the document class? For example, if I create a movie clip in Flash and Export it for Actionscript with the name Foo, I can do this in the document class: var f = new Foo(); this.addChild(f); And it appears on the stage, as it should. But I need to be able to create other instanc...
I am wondering why Qt uses Q before every class name rather than putting everything in a namespace. Is there any particular reason, such as making the names easy to search for, or is it just about brand names? ...
Basically what I want to do is get a start button to initiate a method running in another class and acting on another object.

If I have a java class which is package-private (declared with "class", not "public class"), there is really no difference if the methods inside are declared public or protected or package-private, right? So which should I use, or when should I use which? I'm a bit confused. ...
class Foo { public: void bar(); }; void Foo::bar() { static int n = 0; printf("%d\n", n++); } int main(int argc, char **argv) { Foo *f = new Foo(); f->bar(); delete f; f = new Foo(); f->bar(); delete f; return 0; } Does n reset to 0 after delete'ing and new'ing the class over again? Or is n e...
I am writing a class in Python 2.6.2 that contains a lookup table. Most cases are simple enough that the table contains data. Some of the cases are more complex and I want to be able call a function. However, I'm running into some trouble referencing the function. Here's some sample code: class a: lut = [1, 3, ...
Hello, I gave up on this finally. I am developing something on WordPress 2.8.4.

I would like to be able to do something like (psuedo-code): if (classAvailable) { // do a thing } else { // do a different thing } What would be even better is if I could extend a class from ClassA if it's available or ClassB, if it isn't. I suspect this isn't possible though. ...
