Sprite.rotate uses z-rotation only, i need to rotate it also around the other axes (to achieve simple "3d" effect).

I have this code:
What do you actually mean by "transformation origin"?
#include <SFML/Graphics.hpp>
int main() {
sf::RenderWindow Window(sf::VideoMode(1024, 600), "Test");
sf::Texture Texture;
Texture.loadFromFile("A.png");
sf::Sprite Sprite(Texture);
Sprite.setOrigin(36.0f, 36.0f);
Sprite.setPosition(512.0f, 300.0f);
while (Window.isOpen()) {
sf::Event Event;
while (Window.pollEvent(Event)) {
switch (Event.type) {
case sf::Event::Closed:
Window.close();
break;
}
}
Window.clear(sf::Color::White);
sf::Transform B(std::cos(30.0f), 0.0f, std::sin(30.0f), 0.0f, 1.0f, 0.0f, -std::sin(30.0f), 0.0f, std::cos(30.0f));
Window.draw(Sprite, B);
Window.display();
}
}
int main() {
sf::RenderWindow Window(sf::VideoMode(1024, 600), "Test");
sf::Texture Texture;
Texture.loadFromFile("A.png");
sf::Sprite Sprite(Texture);
Sprite.setOrigin(36.0f, 36.0f);
Sprite.setPosition(512.0f, 300.0f);
while (Window.isOpen()) {
sf::Event Event;
while (Window.pollEvent(Event)) {
switch (Event.type) {
case sf::Event::Closed:
Window.close();
break;
}
}
Window.clear(sf::Color::White);
sf::Transform B(std::cos(30.0f), 0.0f, std::sin(30.0f), 0.0f, 1.0f, 0.0f, -std::sin(30.0f), 0.0f, std::cos(30.0f));
Window.draw(Sprite, B);
Window.display();
}
}

Graphics / xy rotation using transform?
« on: September 09, 2012, 03:44:32 pm »
Hi there!
I was trying to implement xy rotation for my sprite. Only way i could think of was to use transforms with 3x3 rotation matrix. However the image is no longer centered (its position was set to the center of view and the origin was set to half the texture size). The question is, how to rotate it using transforms without repositioning? Thanks

It's the same problem.

I'm having similar problem but my framerate (set with setFramerateLimit(60U)) is sometimes ~40 FPS while other games are running smoothly. Also, i tried using clock for custom framerate regulation but i had the same problem. Also when i was moving with mouse the framerate was bigger (with unlimited framerate), what can cause this? I tried everything, even without any drawing or updating game state the framerate was still low.
