just make sure to move the gifs to your build directory, otherwise it won't work. It will compile+run without the gifs but there just won't be a derpy then.

really, that is awesome, i just looked at what qt creator sais it does, all that i need to do to compile is hit ctrl+r :P
And glad that you could compile it :D

EDIT: so Vogtinator, your fix doesn't work, it still stops running the new gifs after some time/some amount of gifs played, idk which one it is.

You can embed the .gifs as resource (e.g. /gifs/<name>.gif) and load them with ":/gifs/<name>.gif" as filename.

Better practice is to mkdir build, cd build, qmake .. and then make, so the source directory will be kept clean.
It's easier to exclude build in .gitignore than Makefile, *.o and the other output files.

ctrl+b = build and F5 = debug.
BTW: If you use qDebug() << "asdf" instead of std::cout << "asdf", debug output will only be printed in debug build.

F5 will help you ;)

Edit: Some more advice:
- Don't allocate a QMovie everytime you change the animation. Set the filename by using QMovie::setFileName instead.
- To get the screen size use
Code: [Select]
QRect screen = qApp()->desktop()->screenGeometry()- You can use the << operator instead of .append
Code: [Select]
possibleMoveActions.append("fly");
possibleMoveActions.append("flyupsidedown");
//Is the same as
possibleMoveActions << "fly" << "flyupsidedown";
-Use initialization lists:
Code: [Select]
//The contructor
derp() {
posx=500;
posy=500;
}
//does (almost) the same as
derp() : posx(500), posy(500)
{}
-You don't have to use an .ui file, you can add a QLabel as property of your MainWindow and add it using setCentralWidget(label)

thanks for all the tips! so what is the difference with
Code: [Select]
//The contructor
derp() {
posx=500;
posy=500;
}
//does (almost) the same as
derp() : posx(500), posy(500)
{}
as almost is not all the way :P

and that was how i append the lists, i didn't know how to use qlists :P

and a somehow wanne use a ui file, but this project is actually too simple to use one so i should step away from it, just lemme code a bit, maybe magically the bug with derpy vanishing will disappear :D

With initialization lists you can call the constructor of your parent classes and initialize const members.
http://www.cprogramming.com/tutorial/initialization-lists-c++.html
Actually, what happens in
Code: [Select]
class Foo {
private: int i;
public: Foo()
{
i = 1;
}
};
Is that i will be initialized to 0 first (default constructor) and later its value will be set.

That bug hasn't occured to me at all, but I noticed it's still invisible without .gifs.

I guess it is somehow filling up it's ram, i think that I fixed it, i'm testing it atm, i'll just run her for houres ^^

EDIT: All that I got around changing so far is
Quote
- Don't allocate a QMovie everytime you change the animation. Set the filename by using QMovie::setFileName instead.
and the bug seem to be fixed, i'll still do the other suggestions though :D
