View and rectangle "hitbox" problem
« on: February 05, 2021, 10:12:26 am »
Hey, i have really confusing problem. i have just created a button class, and it work fine but when i use view move() method button is moving, but click hitbox is still staying in the same position. I am new at sfml and i have no idea how to solve it.

In the attachment are class .h, .cpp files and main.cpp file.

Help ;c

PS: Sorry for my English

sf::Mouse::getPosition returns coordinates relative to the window, not to the view. You need to translate these coordinates with window.mapPixelToCoords, before doing your click test.

Ye but how can i do that? when i am doing that:

sf::Vector2i pixelPos = sf::Mouse::getPosition(app);
sf::Vector2f worldPos = app.mapPixelToCoords(pixelPos);

nothing happen. I added that line:
button.setButtonPosition(worldPos.x,worldPos.y);
but now my button is always at cursor position

"worldPos" is the mouse position, translated to the same coordinates system as your button. It replaces "sf::Mouse::getPosition(window)" in Button::isButtonClicked.

If you don't understand what you're doing, take some time to think about it. And if you still don't get it, don't hesitate to ask for more explanations.
