Graphics / Collision Class

« on: July 31, 2011, 03:20:45 am »

SFML offers some function that might help you managing collisions. sf::Rect::Intersects() and sf::Rect::Contains(), for example.
But as said before, it's not a game engine.

For future reference I think this topic is one of the best for this subject:

Graphics / Movement Issue

« on: July 29, 2011, 08:46:32 pm »

Hi,
Since you're dealing with real-time input be sure to leave that part of the code out of the GetEvent() loop.
Don't know if that's the case here but here's an example if it is:

Code: [Select]

while(App.IsOpened())
{
               
sf::Event eventUI;

// THIS IS THE EVENT LOOP:
while(App.GetEvent(eventUI))
{
if(eventUI.Type == sf::Event::Closed)
App.Close();

if(eventUI.Type == sf::Event::MouseButtonPressed && eventUI.MouseButton.Button == sf::Mouse::Left)
Fire();
}

// THIS IS A REAL-TIME INPUT:
if(App.GetInput().IsKeyDown(sf::Key::Up))
GoUP();
}

General / Simple operator overloading question

I think that's exactly it.
Thank you!

General / Simple operator overloading question

« on: July 29, 2011, 06:18:00 am »

Hello, I was reading the following page from the wiki:
http://www.sfml-dev.org/wiki/en/sources/richtext

On the following function:

Code: [Select]

RichText & RichText::operator << (const sf::Color &color)
{
myCurrentColor = color;
return *this;
}

What is the "return *this" doing here exactly? Isn't the first line "myCurrentColor = color;" enough to set a new color value?

I know this is probably a simple matter but I came from a C programming background and I haven't mastered Operator Overloading too well yet.

Thanks in advance for the help,
Regards,
Alex.

Probably a silly question but what are the differences between local and global coordinates of a sprite?

General / Loading Resource

Yes, link to a static compilation of SFML (sfml-system-s.lib for example).
It will result in a bigger .exe file but that's pretty much it.

Don't forget the SFML_STATIC preprocessor in your project proprieties if you're using SFML 2.0.

General discussions / List of modifications from SFML 1.6 to 2.0

« on: July 16, 2011, 10:06:38 pm »

On SFML 1.6 sf::Image::SetSmooth() was set to true by default, on SFML 2.0 is set to false, right?
Is it worth adding it to the list?

General discussions / Can somebody help me understand this code?

« on: July 16, 2011, 05:25:20 am »

Hey there. It would be more simple if you pointed out which parts you don't understand.
Just copy-pasting a code makes it too vague and difficult to answer.

Also, warp your source codes with the code button on your post as it makes it easier to understand.
Like so:

Code: [Select]

struct WindowSettings
{
sf::VideoMode videomode;
};

Window / [Solved] How to adjust the delays involved in KeyRepeat?

« on: July 15, 2011, 01:00:32 am »

Maybe you're using SFML 2.0 and that's why you're having trouble understanding what's sf::Input. Read the following doc, it should help you:
http://www.sfml-dev.org/documentation/2.0/classsf_1_1Keyboard.php#details

If you're using SFML 1.6 read the "Getting real-time inputs" section here:

I'm a bit embarrassed to ask because it's probably really simple but,
What replaced the real-time input function GetInput()?

General discussions / Reusable Code and how you deem it reusable quality

« on: July 02, 2011, 11:57:08 pm »

Regarding threads, what can be said about them?
Should they be used often? For example, to separate a physics manager from a resource loader.

I usually keep my programming very linear (no threading), especially because I've never learnt much about thread programming.
But for for advanced situations, where for example I have to deal with a lot of objects, should I start considering that?

By the way I don't mean to thread hi-jack. I tend to take these tips to heart and get pretty interested.

Audio / Loading .ogg Issue

« on: July 01, 2011, 05:27:08 pm »

Are you linking with "sfml-audio.lib" on the additional dependencies?
Did you compile the correct configuration? Example: Compile SFML for "release" and use the "release" configuration when compiling your code.


If nothing works, try to replicate the problem with a minimal code programme.
