Vector erase memory access error [duplicate]
When you call erase, you modify laserList. That makes it invalid, because it pointed into the previous value of laserList. But then you increment it. You can't increment an iterator to contents that no longer exist. That makes no sense.

First, basic Sprite usage from the tutorial. Taken from my own answer on Resizing in SFML 2.0 which, by the way, is the first google result when you search for "sfml sprite fill the screen". First, here's a way to scale the image to the current RenderWindow size. // assuming...
Cannot find module with tag 'sfml'
The experimental support of Android in SFML 2.2 and its examples can be build using cmake and make as described on this wiki page. To enable SFML samples, the SFML_BUILD_EXAMPLES flag has to be set to TRUE when configuring cmake. More build settings are available and presented in the official...
Unresolved Externals using Cmake and Visual Studio 2013
c++,visual-studio-2013,cmake,sfml,unresolved-external
This certainly looks like you've not actually linked any of the three SFML libs successfully. If the find_library calls in the CMakeLists.txt had failed to find the libraries, then CMake would output a fatal error which I'm sure you'd have mentioned. So my best guess is that you're trying to...
SFML - can't get the projectile shooting in the right direction
The problem is that sf::Mouse::getPosition returns the position of the curson in window coordinates while all the entities use world coordinates. You can fix this by using the mapPixelToCoords member function of your sf::RenderWindow object: ... case sf::Event::MouseButtonReleased: { projectile.setPosition(player.x,player.y); sf::Vector2f mousePosition = window.mapPixelToCoords(sf::Mouse::getPosition(window)); float angleShot = atan2(mousePosition.y - projectile.y,...
C++ sfml receives close event just after window opens
From what i have seen, do not use an if statement for checking events, use a switch statement. Also Use a while(window.isOpen()) when trying to poll events Have you read through the tutorials on http://www.sfml-dev.org ? Because i can guarantee that it is the best source for learning sfml. Use...
Tricky bugs in refacored pong from sfml examples
The first error tells you everything you need to know: In file included from /usr/include/SFML/System/Lock.hpp:32:0, from /usr/include/SFML/System.hpp:36, from /usr/include/SFML/Window.hpp:32, from /usr/include/SFML/Graphics.hpp:32, from main.cpp:5: /usr/include/SFML/System/NonCopyable.hpp: In copy constructor ‘sf::Window::Window(const sf::Window&)’: /usr/include/SFML/System/NonCopyable.hpp:67:5: error: ‘sf::NonCopyable::NonCopyable(const sf::NonCopyable&)’ is private NonCopyable(const NonCopyable&); A Window is,...
Issues Configuring CLion, Cmake, and SFML
Your question says the full path to the find module is /Users/Home/SFML-2.2-osx-clang-universal/cmake/Modules/FindSFML.cmake But you're adding ${CMAKE_SOURCE_DIR}/Users/Home/SFML-2.2-osx-clang-universal/cmake/Modules to your CMAKE_MODULE_PATH. ${CMAKE_SOURCE_DIR} is the absolute path to the directory containing the top-level CMakeLists.txt file. If you know the absolute path to the module file you want to include, you should most certainly...
