General / Re: Undefined Reference Error

« on: October 03, 2023, 10:18:20 pm »

Yes, I have linked sfml and defined SFML_STATIC. It was actually gcc version problem, I think. When I used prebuilt library of 2.6, it compiled without any error but when I run the app I get:- "libgcc_s_seh-1.dll not found" error. When I compiled sfml with tdm-gcc 10 I got this undefined reference error. So I removed tdm-gcc and downloaded codeblock with compiler and downloaded sfml 2.5. Now it is working without error.

General / Undefined Reference Error

I just compiled SFML using cmake. And it only build static lib I think. I have attached the image of the build. Now when I try to compile hello world it says -

(click to show/hide)

undefined reference to `sf::VideoMode::VideoMode

Prebuild SFML is also showing same error. Version 2.6.

General / Re: Entity Selection box using zoom

« on: January 11, 2020, 09:22:41 am »

I am doing like this

setView(mainView)
sprite.draw(*this);
selection.draw(*this);

setView(overlayView);
sf::Vector2f position = selection.getPosition();
sf::Vector2f scale = selection.getScale();
mapPixelToCoords( mapCoordsToPixel( position, mainView), overlayView);
mapPixelToCoords( mapCoordsToPixel( scale, mainView), overlayView);
 

It is not mapping the pixel. I am getting the same result like image 2.

Thanks for reply.

Yes, it works if I draw it in same view, but than the rectangle also get zoomed in.
I have attached an image.
Image 1 is 100%, but when I zoom it, its pixel size increases like image 2. I want to keep the pixel size of the rectangle same pixel like image 3, bottom.

Thanks for reply.

General / Entity Selection box using zoom

« on: January 09, 2020, 08:27:26 pm »

Hi,
   Need a little help to draw a rectangle shape after zooming an entity(image).
   I am using view class to zoom an image. I have two view -
   1/ that draws the images, main view
   2/ to draw the rectangle, overlay view
Everything is working fine. But the problem comes when I zoom an image using main.zoom(200%), normal is 100%. The image size increases, My question is, how do I make the overlay rectangle zoom with main view, without changing its pixel size. I have attached an image. This is a selection rectangle that every application uses to show the user that an image is selected.

The right side(100%) and left side(200%) image is what I am getting. What I actually want to make is the third(bottom) image.

I am using SFML and wxWidgets.

Thanks in advance.

Hi,
   There is a method RenderWindow::capture which save all window as an image. Is it possible to save just those images which are inside a rectangleShape?
   I have attached an image, I just want to save the inner area. Which is a rectangleShape.

Thank you

This is how I am using my mouse pick,

Code: [Select]

mMousePos = sf::Mouse::getPosition(*this);
mWorldPos = mapPixelToCoords(static_cast<sf::Vector2i>(mMousePos));
And the picking function,

Code: [Select]

bool Entity::isPointInside(const sf::Vector2f& point)
{
    if(mSprite.getGlobalBounds().contains(point))
        return true;

    return false;
}

Thank you.

General / Double view and mouse position[SOLVED]

« on: August 11, 2015, 04:00:34 pm »

Hi,
   

   window.clear();

   //Render the sprites
   window.setView(MainView);
   window.draw(Hero);

   //Render others
   window.setView(GuiView);
   if(_dragging)
      window.draw(Box);

   window.display();
   

   The problem is, if I zoom the MainView, the mouse picking no longer works. But if I remove the GuiView, mouse picking works. How do I update the bounds of the Hero sprite after zooming out the MainView, so that I can pick it with mouse?

Thanks in advance.

That mean I have to call view.setView continuously in loop. Is it ok?

Hi,
   When view is zoom in/out everything zoom in/out with it. Now I have some gui onscreen, which I don't want to zoom with map. How do I do it?

Thank you.

Graphics / Re: View zoom and mouse coordinate?

« on: June 15, 2014, 05:56:51 pm »

damn me, there was a zoom variable I used to zoom the viewport, which I was using to subdivide the rect of the view. I have so many files that I totally forgot about that variable. Just found it, and everything is working correctly .

Thank you for your reply.

I mean calling the isPointInside() function.
I just print out all the values and found that everything is working fine except this -

Code: [Select]

MousePos = window.mapPixelToCoords(PixelPos, view);It always returns the Dimension of my window( also view), which is 1024x768. Even PixelPos is returning the correct mouse position, relative to my window.

EDIT: and when I set the zoom of view to 2 it returns - 1536x1050.

Here is what I tried -
Getting the mouse position -

Code: [Select]

sf::Vector2i PixelPos = sf::Mouse::getPosition(window);
MousePos = window.mapPixelToCoords(PixelPos, view);
Here is the checking -

Code: [Select]

bool Entity::isPointInside(sf::Vector2i input)
{
    if(boundRect.contains(input))
    {
        return true;
    }

    return false;
}
Then I just check the MousePos, it is inside or not.
