How to free sf::Texture during runtime
« on: October 29, 2012, 03:51:45 pm »
Hello.
I am making a game, and at main menu i have allot of images, and i am wondering how to "free / empty" them to improve performance during game, i will reload them once menu is up.

I thought about reloading 1x1 image, that would work.
But id really prefer to empty it somehow.
What are ways to do this?

Sorry we have no idea what you're referring to. You either need to describe very detailed what you're doing, or waay better post a minimal example...

If you have different states (like menu, game, credits, etc) then it's best to use some kind of a state manager. There each state could be represented as class, then you can load stuff in the constructor and if the class gets removed the resource will be freed. As an example you could take a look at my SmallGameEngine. ;)

Why would you keep an empty sf::Texture instance? Just destroy it, and create a new one when you need to reload the texture.

Or, if you don't want to use dynamic allocation:
texture = sf::Texture();

And are you sure that you really need to do that? Unless your video memory is full, it won't make any difference.

That's what i am doing at the moment,

What i was asking, is there a function to clear it and keep the object.
"I don't know how to make a code box"
int main
{
sf::Texture a;
a.loadFromFile("somefile.png");
//Something happens
//Unload the image somehow
//Something happens
//Load the image again
}

I am currently loading it intro std::vector and freeing it when i don't need it.

The challenge is to make it as least memory requiring as possible.
