Graphics / Re: SFML Draw() won't draw sprite on Window

« on: October 15, 2020, 11:26:56 pm »

I'm wondering why I had to add that line (ship = Ship() Is it the same as ship.Ship() ?). I'm pretty new to c++ so I still have a lot to learn.

Because at the moment when global variable get values (i.e. constructor is called) your texture is not yet loaded (it's loading from file inside main function). No, it's not the same (I'm not even sure that ship.Ship() compiled)

About your bullet sprite problem...
Did you try to add setUp method also for bullet?

Well now it's obvious - (btw, code still doesn't compile), your texture load after initialization of global variable.
For quick fix add right after loading e.g:

    textureLoad();
    ship = Ship();

But I strongly recommend refactor all code.

In that case can you provide complete (minimal if possible) code for reproducing the behaviour?
Or maybe your project is on Github, Gitlab or something like that?

In examples folder (located inside main lib folder) or you can get it from Github - https://github.com/SFML/SFML/tree/master/examples/pong

If I define paths manually:

set(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "SFML-2.5.1\\extlibs\\headers")   
set(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "SFML-2.5.1\\extlibs\\libs-msvc\\x86")   

CMAKE generate project files.

Yes, I've also outputed the position and it says that is at y = 666.
However 5 / 6 != 0
The setPosition(WIDTH / 2, HEIGHT * 5 / 6) means to put the sprite at the 5 / 6 of the screen height, so in the lower part

It probably expected to be so, but because both operands are integer C++ will use integer operations.

#include <iostream>

int main() {
        std::cout<<5 / 6<<'\n';
}

Output: 0

Of course in your code HEIGHT * 5 part is evaluate first, so it won't be 0.

Looks promising, but why not use and contribute to some already existed project(for example SFGraphing)? Because there are a lots projects with basic chart support (line, scatter,...) but I didn't find any that has support for more advance charts (like time series or candlestick chart).

I want to use SFML with CMAKE but get error:

CMake Error at /SFML-2.5.1/build/SFMLConfig.cmake:139 (message):
  SFML found but some of its dependencies are missing ( FreeType OpenAL
  VorbisFile VorbisEnc Vorbis Ogg FLAC)
Call Stack (most recent call first):
  CMakeLists.txt:11 (find_package)


CMake Error at CMakeLists.txt:11 (find_package):
  Found package configuration file:

    /SFML-2.5.1/build/SFMLConfig.cmake

  but it set SFML_FOUND to FALSE so package "SFML" is considered to be NOT
  FOUND.


Configuring incomplete, errors occurred!

CMake file:

cmake_minimum_required(VERSION 3.1)

project(SFMLTest)

## If you want to link SFML statically
set(SFML_STATIC_LIBRARIES TRUE)

## In most cases better set in the CMake cache
set(SFML_DIR "SFML-2.5.1\\build")

find_package(SFML 2.5.1 COMPONENTS graphics audio REQUIRED)
add_executable(SFMLTest appl.cpp)
target_link_libraries(SFMLTest sfml-graphics)

I use static SFML 2.5.1 that built myself with CMAKE.

Are you sure that you built static version of SFML?
