That actually keeps tripping me up, lately. I'm so used to variable and pointer being identical that it fields weird to have to explicitly declare them. The implicit creation of new stuff on assignment just feels odd.

I see what you did there.

Fantastic wall of text, Alway. I love reading stuff like that. All those links were awesome.


Anyway, I have yet another complex question about the basics of C++.

Code: [Select]
class Thing{

// stuff

};

Thing one;

int main(){

Thing two = Thing();

one = two; // this here

}

What exactly happens at the commented line? Does one reference the same thing as two? Or does it create a copy or something?

It's always annoyed me how the sound positioning in first-person games is always crap. If an NPC is two floors above me, I can somehow hear their footsteps perfectly clearly. If anyone fires a gun in Counter-Strike, I know exactly where they are. And yet people spend hundreds of dollars on surround sound setups.

That looks amazing. Hopefully this technique will eventually become standard for all FPSs. Wait, that video is from 2009... Damnit game developers, stop spending money on better graphics. The graphics equivalent of today's sound is like having unshaded, untextured models.

Thanks! You are all awesome people.

Also of note, the OS will typically clean up anything you forgot upon the program exiting; though relying on this is typically considered bad form.

Your use of the word "typically" frightens me. At times, I have not turned off my computer for months at a time. If I'm always launching and exiting a program that has lots of memory leaks, will the OS always clean up after the program, or...?

I've a question about C++ and dynamic memory: I've been thinking that whenever there is a "new" somewhere in the code, there should always, always be a "delete" or "delete[]" somewhere else. Is this a reasonable guideline?

Your first link got me going in the right direction. Thanks!

I think these two lines are basically the same:

Code: (C#) [Select]
if(Ball is T)

Code: (C++) [Select]
if(typeid(Ball) == typeid(T))

So apparently I can just do "new T", like this:

Code: (C++) [Select]
template<typename T>
T Instantiate(){
     
     return *(new T);
     
}

That's useful, but it's just part of what I'm doing. What if I want to compare if a variable is of a certain type? In C# it looks like this:

Code: (C#) [Select]
bool Test<T>(){
     
     Ball ball = new Ball();
     
     return ball is T;
     
}

I would like to instantiate an arbitrary class in C++. I know how to do this in C#:

Code: [Select]
T Instantiate<T>() where T : new(){
     
     T instance = new T();
     
     return instance;
     
}

The above code creates an instance of the type passed to it. If you wanted to make a Ball, it would work like this:

Code: [Select]
Ball b = Instantiate<Ball>();


How do I do this with C++? I am aware of templates, but there has to be a better way.

Life Advice / Re: The Computer Technical Thread:Thermal Compounds (throw that oem heatsink away!)

My comp makes weird loud grinding noises when I turn it on, they quiet down in about 20 mins but it's still pretty loud. Thinking the fan is loose or something, but I already cleaned the comp of dust (took it completely apart, cleaned fans + heatsink, etc) but the noise is still there. What do?

I recently had two 120mm fans start to do this to me. They would make noise like you describe, but I could fiddle with them to stop the noise. Really annoying. Luckily I had two recently purchased fans I was using, so they were replaced without a problem. I think it's a good idea to buy a bunch of cheap fans in case any of the ones you're using break.

Oh, Java, that must be where I heard it from; probably one of the programming threads on here. Also, with my forgetting the quotation marks, you can tell I rely on my F7 key too much...

Excellent tutorial!

One thing I don't understand (I've done suprising little with C++ strings) is this:

Code: [Select]
if(function == "add")
I thought you had to do
Code: [Select]
if(function.compare(add) == 0)or else it wouldn't work.

The next topic we should discuss is the practically application for one man fighters.

Drones are better. End of story.
- Humans can only take about 9 Gs before blacking out. Drones don't have this problem. They can accelerate at 1000 Gs if the ship allows it to.
- No need to make room for squishy living things. Smaller space, less mass.
- Copies can be made easily, while humans are irreplaceable. (Which makes me wonder how death in 0x10^c will work...)

The only problem would be developing an AI that is good enough (which, let's be honest, some expert AI programmer will develop within a day).
