General / sf::Text blurry

« on: October 15, 2011, 05:32:26 pm »

Hello all,

When i change the character size of my text, it gets blurry...
Is this a known issue?

Any work-arounds?

Thanks,
Xander

You don't understand, that means you can't pass the function...

I tried it, but it doesnt work:

Code: [Select]

error: ISO C++ forbids taking the address of an unqualified or parenthesized non-static member function to form a pointer to member function.  Say '&A::test'|

Yes, but then it should be called like this:

Code: [Select]

button.setOnClickCallback(bind(&A::test, &testclass));

Do you think that would be acceptable?
Or I could overload the function, one which takes just a function, and one which takes an object and a function (and call boost::bind() inside that function)

It's just that I don't know how to write a function that takes an object and an object's function...

I tried with boost::bind() but I couldn't get it to work. I mean, I should pass an object and one of his functions to setOnClickCallback() right?

I'm stuck! I can't figure out how to set a member function as a callback...
A normal function works perfectly:

I use typedef boost::function<void ()> callback.
But when I call my setCallback function with a member var it doesnt compile...

I don't see  a reason to start with 1.6 now. 2.0 is right around the corner

Wow thanks for the awesome input Nexus
I decided to store a sf::FloatRect in the class.
Drawing:

Code: [Select]

void Draw(sf::RenderWindow* window)
{
    window->Draw(sf::Shape::Rectangle(box, fillColor, 3, outlineColor);
}

I've never worked with callbacks before, but it looks good
How would they work?
I store a function pointer in the object, and when (in checkEvent(const sf::Event& event) ) it detects that the mouse hovers over it, it calls it. Right?

I feel I'm going to learn so much from this [/code]

Hey forum,

I'm playing around with the idea of making a GUI library.
I have some design decisions to make and I brainstormed a bit while I was at school. I have some questions though:

- Is using sf::Shape for drawing the boxes a good idea?

- And should I derive from sf::Drawable or make a

Code: [Select]

void draw(sf::RenderWindow* window) function?

- How could I stretch and shrink buttons if I'd use images. I know I could make one image part for the middle (which I can stretch) and one for the sides. Are there any other methods to do this?

- For event checking, what would be a better approach:

Code: [Select]

void checkEvent(const sf::Event& event) //which checks all the possibilites

Or

Code: [Select]

void onHover()
void onClick()

Which are to be called manually? I'm leaning more towards the first.

Thanks in advance.

PS: If it goes well, I'll ofcourse make it public so other users can benefit from it too [/code]

Graphics / SIGSEGV fault while using thor::FrameAnimation

« on: September 01, 2011, 09:18:57 am »

OMG!
I feel so stupid, 2 noob mistakes in 2 days
thanks, it works great now!

EDIT: How do I know when the animation finishes? Should I set my own sf::Clock for that? Because after it finishes I don't need to draw it anymore.

Graphics / SIGSEGV fault while using thor::FrameAnimation

It is stored...
Here's how I init:

Code: [Select]

void GameState::initAni()
{
    explosionSprite.SetTexture(im.getImage("explosion18.png"));
for(unsigned i = 0; i < 2050; i+=128)
        for(unsigned j = 0; j < 2050; j+= 128)
        {
            sf::IntRect temp(j, i, 128, 128);
            ani->AddFrame(1.f, temp);
        }
    ani->Apply(explosionSprite, 1.f);
    animator.AddAnimation("explosion", ani, 2);
}


Then I call:

Code: [Select]

void GameState::playExplosion(float x, float y)
{
    explosionSprite.SetPosition(x+50, y+50);
    animator.PlayAnimation("explosion");
    explosionCount++;
}[/quote]

Graphics / SIGSEGV fault while using thor::FrameAnimation

I succesfully tested FrameAnimation to make an explosion, but when I use it in my game, it gives me a runtime error.

Code: [Select]

Assertion failed: itr != mAnimationMap.end()
in animator class

??

Graphics / SIGSEGV fault while using thor::FrameAnimation

« on: August 30, 2011, 11:10:16 pm »

So I was checking out this awesome lib called Thor
This is my code snippet:

Code: [Select]

for(int i = 0; i < 701; i+=100)
        for(int j = 0; j < 701; j+= 100)
        {
            sf::IntRect temp(sf::Vector2i(i, j), sf::Vector2i(100, 100));
            ani->AddFrame(1, temp);
        }
    ani->Apply(spr, 50);
ani is a FrameAnimation ptr.

I really don't understand how that could happen...
The SIGSEGV points to a fault with a vector (probs the one that FrameAnimation class uses?)
