#5226495 Random Number Generation

Posted by Lactose! on 30 April 2015 - 07:22 AM


samoth made a suggestion for 512-bit encryption.  Why not 1024- or 2048- or 4096-bit?

Because using 512 is already using a nuke to kill a fly trapped in a tiny box.

At some point you're going to have to realize that more firepower won't make the fly any deader.

As far as the actual numbers, I guess I never really did the math - I just know that ...

I do know quite a bit about security, especially cryptography

This just reeks of the Dunning–Kruger effect.

 

Do you honestly believe that whatever data you're transmitting needs to be more secure than (for example) the entire world's financial systems, military secrets or government branches who specialize in this stuff?

If you answer yes, you are either deluded, or you are trolling.

#5225025 sfml player doesnt seem to move

Posted by Lactose! on 23 April 2015 - 07:45 AM


I put it like that because I wasnt able to load the game with it in the .h file

As I said, you need to use a player that's inside Game somewhere (since we don't want to use filthy globals). This can be either a pointer/reference, or an instance.

If you tried doing that, but got errors with it, you need to post that code, so we can see what you did wrong.

I was using Player player inside the game.h file. It runs once and then i get a weird error which doesn't make sence:

Image doesn't load, but you are incorrect.

 

void Game::OnKeyDown(){
	Player player; //This creates a new instance of the player
	player.OnKeyDown(); //This uses the newly created instance of the player
} //The new instance of the player goes out of scope and is destroyed.


void Game::Draw(sf::RenderWindow &window){
	Player player; //Same as above
	player.Draw(window);
}

You create a new player every time you enter the OnKeyDown function.

Your Game class needs to contain an instance/reference/pointer to a Player.

Currently, you create a new player in both Game::OnKeyDown and Game::Draw, and in both cases your player instance is destroyed upon leaving the function (out of scope).




#5224478 sfml sprite wont draw

Posted by Lactose! on 20 April 2015 - 07:03 AM

You draw in game.Update().

Then you clear the window, probably erasing the stuff you drew inside game.Update().

Then you display the cleared window.

 

As an aside, I would recommend splitting updates from draws, to prevent this kind of thing.




#5223767 Rate my Game Loop

Posted by Lactose! on 16 April 2015 - 01:00 PM

What you want to do is fix your timestep. This ensures your game's simulation behaves identically given the same input, even if frame rates differ. For example, a person with a slow computer vs a person with a super high-end computer.

#5219811 How do you motivate yourself for game design?

Posted by Lactose! on 28 March 2015 - 07:56 AM


The person who asks how to be motivated in the first place will never be the person who stays up all night to explore to its fullest his or her algorithm.
End.

The person who mistakes personal opinion and belief with absolute fact will have 17% less purple dreams than other people.

Bus stop.

 

 

Slightly more on topic: your post is falsifiable, since you posit it in absolutes. It is also false. I've had motivational issues and sought assistance with it, while later on sitting up all night with the very same subject.




#5219797 How do you motivate yourself for game design?

Unfortunately, your following text doesn’t change my mind.
 

dreamer1986, on 28 Mar 2015 - 08:11 AM, said:
every one of you was highly motivated from the start, and kept their motivation high at all times? I find that very hard to believe

This lack of belief is exactly why I got my first impression of you.
If I wasn’t highly motivated from the start, why would I have started?

Your response seems to ignore the AND part of that question. [EDIT: Selective Quote messed up the formatting of the nested quotes, I tried adjusting it after for it to make some sense.]

---

Motivation can and will have periods of ups and downs. There are times you'll feel so motivated you'll stay up all night (even when you know you probably shouldn't), just to continue working on something because you enjoy it so much in the moment you can't stop.

But on the flip-side, there can and will be moments where even sitting down for 5 minutes might feel like a nuisance. This can be caused by a whole myriad of things, not all of which are in your control.

 

Like most people here have said already, you should figure out if this is something you really want to do. Does the thought of doing this kind of work for years and years sound like what you really want to do? The book suggested might help you figure this out.

 

Just be aware that motivation isn't a constant state. It will falter and it will rise, regardless of what profession or activity you're engaged in. It doesn't matter if it's work, a hobby, exercise or what have you. What I've found for myself, is that if you truly enjoy the profession or activity, motivation (on average) will remain high, even though there might be days where it's not like that at all.

It might also simply be because you enjoy doing it yourself.

 

Doing what you enjoy can be a huge boost in morale/productivity.
