texture and sprite
« on: May 09, 2015, 06:15:07 pm »
Can i load more than one image to texture and set texture to sprite?

example:
sf::Texture texture;
texture.loadFromFile("image1.png");
texture.loadFromFile("image2.png");

does the image1 get destroyed? if not how can i choose which image i want to render.
example:
sprite.setTexture(texture.choosewhatiwanttoset("image1.png"));
sprite.setTexture(texture.choosewhatiwanttoset("image2.png"));
...
same question for sprite,
window.draw(sprite.choosewhatiwanttorender("image1.png"));

thanks

Short: No, yes.
Long: No you cannot load multiple "images" intro one sf::Texture, You can use/set sprite to draw a sf::Texture

does the image1 get destroyed? if not how can i choose which image i want to render.
Short: yes, ?
Long: The image1.png will be released/destroyed, and image2.png will be loaded.

Global answer: You probably want to make two sf::Texture and load each one with different image.
Then you can use sf::Sprite to chose which one you want to draw via sf::Sprite spr1; spr1.setTexture(...) function. That's how you can go around switching around what you want to draw.

i mean can i set more then one texture to sprite without the previous texture getting destroyed,
but you already answered it in global answer.

thanks :)

@BaneTrapper

by the way, would you recommend having one sprite object for each tetxture object? so you will only load 1 time per texture, instead of one sprite for more than one texture

Sprites setTexture(...) function is cheap, you can use only one sprite, and change texture which you want to display/draw.

In the end it depends on what you want to do, there shouldn't be any noticeable difference doing it ether way.
