Title: problem with SetSubRect
Post by: stevend on August 11, 2009, 07:44:21 am

ok so here is my code:

(i am using the resource manager to manage images found in the wiki)

Code: [Select]


sf::Image* image = gImageManager.getResource( tilesetfilelocation );
if( image != NULL )
{
sf::Sprite sprite;
sprite.SetImage( *image );

sprite.SetSubRect(sf::IntRect(32, 32, 32, 32));
sprite.SetCenter(0,0);

sprite.SetPosition((float)32,(float)32);
map.push_back(sprite);
}
else
cout << "File not found! " << tilesetfilelocation << endl;


my problem is that when is when i comment out this, and draw all the sprites (map is a vector array of sprites)

Code: [Select]


sprite.SetSubRect(sf::IntRect(32, 32, 32, 32));


it draws the entire image fine. but when i attempt to draw one tile from this by leaving the above line UNcommented i get nothing.

i cant get SetSubRect to work for the life of me.

the image i am using is a tile set with 32x32 tiles in jpg format, one used by rpgmaker.

any ideas?

Sure :)

As you can see it's not (x, y, width, height) but (left, top, right, bottom).
