Checking if the mouse is on a sprite

[Kladdy]

So in all of my SFML development, i've been doing manual checks to see if the mouse is currently hovering over a sprites area by comparing the current positions to the outer sides of the sprite. This is kind of annoying after a while if you have many buttons, and I'm just wondering if there was any function that I could use in order to get this result, some thing like mouseOnSprite(SpriteName);

Thanks

You can build such a function by combining sf::Sprite::getGlobalBounds() and sf::Rect::contains()

Thank you, this will help a lot!

I'm having a problem tho. The getGlobalBounds function returns a sf::Rect<float>. I have no idea how to convert it to a regular float, and there doesn't seem to be anything online.

Why do you want to convert sf::Rect<float> to simple float?

Just use

yourRect.contains(MousePosition) == bool

What do you mean? The sf::Rect class is fully documented here: http://www.sfml-dev.org/documentation/2.2/classsf_1_1Rect.php

I have almost the same question. I'm just learing SFML, and copying a code from youtube tutorial. I've did everything exactly the same as the tutorial creator, and his code was compiled my wasn't.

It's like that :

ivoid MainMenu::Update(FrameWork &frame, sf::RenderWindow &updatetarget, float frametime)
{
   if (button[0].getGlobalBounds().contains(sf::Mouse::getPosition(updatetarget).x, sf::Mouse::getPosition(updatetarget).y) &&
      (button[0].getColor() != sf::Color::Red))
   {
      button[0].setColor(sf::Color::Blue);
      playselect = true;
   }
   else if (!button[0].getGlobalBounds().contains(sf::Mouse::getPosition(updatetarget).x, sf::Mouse::getPosition(updatetarget).y)
      && (button[0].getColor() == sf::Color::White)
   {
      button[0].setColor(sf::Color::White);
      playselect = false;
   }
}

Where button is array of text. Error occures in place where i check if mouse position is on texture. lines :

if (button[0].getGlobalBounds().contains(sf::Mouse::getPosition(updatetarget).x, sf::Mouse::getPosition(updatetarget).y)

!button[0].getGlobalBounds().contains(sf::Mouse::getPosition(updatetarget).x, sf::Mouse::getPosition(updatetarget).y)

Type of error :

syntax error : '::'
'(' : illegal token on right side of '::'

Could anyone help me ? I'm new to programing.
Thanks a lot!

You should create your own thread unless it's really about exactly the same thing and use the [code=cpp][/code] tags.
Next you should gather more experience with C++ and compiler errors if you can't figure out what the error message means...

else if (!button[0].getGlobalBounds().contains(sf::Mouse::getPosition(updatetarget).x, sf::Mouse::getPosition(updatetarget).y)
      && (button[0].getColor() == sf::Color::White)

You never close the if( statement.
