General / Rotating a drawing from its center

« on: January 14, 2024, 04:51:24 pm »

I've tried looking for someone having a similar issue to me, and could not find anything close.
I am trying to create a basic geometry dash copy, and I am having a lot of issues rotating my player square. I am able to rotate it in mid air, just like in geometry dash, but it is rotating with the origin being the top left of the square. This causes a couple of issues for me, but I am only looking to find a solution as to how I can get the origin of rotation to be the center of the square, allowing me to jump and rotate in place. Here is the code and a short gif of the behaviour:

if (!onGround) {
    // Set the origin to the center of the player for rotation
    squarePlayer.setOrigin(0.5f * squarePlayer.getSize());

   float rotationFactor = 180.f * velocityY / sqrt(2.f * jumpHeight * gravity);
    squarePlayer.setRotation(rotationFactor);

    // Draw the player square
    window.draw(squarePlayer);

   // Reset the origin back to the top-left corner after rotation
    squarePlayer.setOrigin(sf::Vector2f(0, 0));
}
else {
    // Draw the player square without rotation
    window.draw(squarePlayer);
}
