SFML projects / Drawable group class
« on: May 17, 2018, 03:26:36 pm »
I made a class that can store classes that is derived from drawables...I made two :
this one just makes it easier to draw multiple objects, it has a function that can make it so it won't draw one of them, or you can just make the group invisible, it is named ObserveGroup
https://github.com/Flaze07/useful-stuff/tree/master/for%20sfml/ObserveGroup
the second one has complete ownership over the objects, just like the ObserveGroup, this one can make one of the objects invisible, or itself invisible :

« on: May 14, 2018, 09:30:11 am »
wait, isn't it better to cast the windowSize rather than creating an object ? I mean
although I don't know very well.... I hope someone would clear me on this
camera.setSize( Vector2f{ window.getSize() } );
isn't this better ?camera.setSize( static_cast< Vector2f >( window.getSize() );

Hmm.. I wonder why obstacle.fall( 10 ) would give out an error "obstacle.fall( 10 ) is not of type Obstacle"...never got one of those...why not post Obstacle class too 
also to answer your question
you still need to call ( I am pretty sure )
I learnt C++ here : http://www.cplusplus.com/doc/tutorial/ although the site has bad reputation, it works for me
best way to learn C++ is through books
also to answer your question
Foo *foo = new Foo( "Foo", 4, 4);
you still need to call ( I am pretty sure )
delete foo;
if you use unique_ptr ( which is the correct way since C++11. Unless you really need raw pointer )std::unique_ptr< Foo > foo = std::make_unique( new Foo{ "Foo", 4, 4 } );
there is no need to call deleteI learnt C++ here : http://www.cplusplus.com/doc/tutorial/ although the site has bad reputation, it works for me

Audio / Re: Sometimes Audio not loading
« on: May 12, 2018, 04:52:21 am »
sometimes as in, there are times when it successfully worked, and there are times when it won't load ( I used two sf::SoundBuffer ), both of them fails to load.
I run it like this
i.e. my .exe is in C:\Program Files\game\game.exe
so my sound is in C:\Program Files\game\media\sound.wav

« on: May 11, 2018, 04:51:09 pm »
This has been bugging me for a while...sometimes, when I load my application, the sound won't load and by won't load I mean
sf::Sound::loadFromFile() return false;
why does this happen ?, also if code is needed, please tell me

Graphics / transforming on each vertex array
« on: May 01, 2018, 11:45:49 am »
for example :
each of the rect will have different rotations.
I know how to apply transform to vertex array, but if I want the vertex array to have different roations, how do I do that ?
std::vector< sf::RectangleShape > rect;
//stuffs
int i = 0;
for ( auto& a : rect )
{
++i;
rect.setRotation( 90 + i );
}
//stuffs
int i = 0;
for ( auto& a : rect )
{
++i;
rect.setRotation( 90 + i );
}
each of the rect will have different rotations.
I know how to apply transform to vertex array, but if I want the vertex array to have different roations, how do I do that ?
sf::VertexArray vert{ sf::Quads, 8 };
//stufs
sf::Transform t;
t.setRotation( 90 );
win.draw( vert, t ) // unable to set rotation for each 4 vertices
//stufs
sf::Transform t;
t.setRotation( 90 );
win.draw( vert, t ) // unable to set rotation for each 4 vertices

General / How do you make .DLLs with CMake ??
« on: April 07, 2018, 11:31:04 am »
Look, I know that CMake is not a compiler (because it says so in the tutorial to "compile" sfml) but, if I cannot make a .dlls how do I use the library that I built with CMake ?
(Also, this is a problem regarding thor, because I need to build it with CMake, with SFML, there is no problem with just using the pre-compiled ones)
Ok, just realized that I can actually use the .cbp to compile it with CodeBlocks, and it kinda works because it suddenly terminates after 1 minute and 18 seconds
NVM, it worked, it created one .dll and another of .dll.a
?
Edit : Nevermind it worked, and I can successfully integrate THOR into my Project, but why is it thorlib.dll.a instead of just .a
