Okay, thanks!

PS: Even more off-topic: What is the word that includes both mouse buttons and keyboard keys? I need it for my inputManager class

Thank you so much for the elaborate answer!

I asked a friend of mine today the same question and he too replied that external libraries should not be in git.

When it comes to large files, couldn't you just use git LFS, though?

Oh right! On linux you install SFML globally! Well, I am now definately switching.

Would you put the name of the library into .gitignore or .git/info/exclude on other operating systems?

General discussions / How to use SFML on git

« on: January 22, 2017, 06:20:06 pm »

Hi,

this topic may be a bit SFML-unrelated, so please forgive me.

How should I use git in a cross-platform git project?

My 3 ideas

• Copy the download for the specific compiler into the repository
  Problems: The graph shows 22k additions on the first commit, which are not mine. The library is OS/Compiler-specific
• Create a separate repository for SFML and put the download in there and use it as a submodule in your actual repo
  This fixes Problem 1, but the second one still remains
• Use the official SFML repo as a submodule
  Problem: How do you use SFML in it's raw state? Do you have to add all necessary cpp files to the makefile?

It's outside, so 15 for anyone looking for the answer.

Let's say we have an

sf::CircleShape c(10)

If we now set

c.setOutlineThickness(5)

is the Radius of the Circle 10 or 15?

Thanks, Kim

Thanks! Makes sense

General / Re: Converting sf::Event::MouseMoveEvent to sf::Vector2i

Okay, thanks, but it is not possible to cast it all at once, you do have to make a new vector from the x and y values?

General / Converting sf::Event::MouseMoveEvent to sf::Vector2i

« on: November 14, 2016, 02:42:43 pm »

Let's say we have

sf::Vector2i v;

We get

error: conversion from 'sf::Event::MouseMoveEvent' to non-scalar type 'sf::Vector2i {aka sf::Vector2<int>}' requested

when doing

v = event.mouseMove;

The following works fine, but is ugly

v = sf::Vector2i(event.mouseMove.x, event.mouseMove.y)

There also is no explicit conversion.

Is there a nicer way of doing this?

Thanks,
Kim

PS: A bit off-topic, but why does Vector2 have no parenthesis overload?

Do the following code snippets do the exact same thing?

while (window.isOpen)
{
        sf::Event event;
        while (window.pollEvent(event))
        {
                if (event.type == sf::Event::mouseButtonPressed)
                {
                        // Do something here
                }
       
        } // Poll Events

} // Game Loop
 

bool bolean;

while (window.isOpen)
{
        bolean = false;

        sf::Event event;
        while (window.pollEvent(event))
        {
                if (event.type == sf::Event::mouseButtonPressed)
                {
                        boolean = true;
                }
       
        } // Poll Events

        if (boolean)
        {
                // Do the same thing here
        }

} // Gameloop
 

I am asking this, because you mentioned some sort of delay and timing in my last question and I want to know, if I am understanding this right, so sorry if this question seems stupid.

Thanks,
Kim

General / Re: Mouse::isButtonPressed(Mouse::Left) vs (event.mouseButton.button == Mouse::Left)

« on: November 05, 2016, 11:25:47 pm »

Sure it would:

std::optional<sf::Mouse::Button> button;
if (event.type == sf::Event::KeyReleased) button.reset();
if (event.type == sf::Event::KeyPressed) button = event.mouseButton.button

(Or whatever the button identifier is).

std::optional

would really help with this, but MinGW doesn't support it yet...

How do you get the state of the key, when no KeyPressed event is triggered, though? As I said, I need both options and I want to make them work the same way.

Okay, very interesting. But, so you would completely avoid events and just check if last frame the mouse button was pressed and if the state changed? Since I need both in my application and it needs to be consistent, in the sense that I have a handleInput function and I pass it whether it was called from inside the event handler or from the isButtonPressed Testing.
