c++ - Mirroring the Y axis in SFML -
hey i'm integrating box2d , sfml, , box2d has same odd, mirrored y-axis coordinate system sfml, meaning rendered upside down. there kind of function or short amount of code can put mirrors window's render contents?
i'm thinking can put in sf::view this...
how can flip y-axis easily, rendering purposes, not effecting bodies dimensions/locations?
i don't know box2d when wanted flip y axis using opengl, applied negative scaling factor projection matrix, like:
glmatrixmode(gl_projection); glloadidentity(); glscalef(1.0f, -1.0f, 1.0f); if want independent of opengl apply sf::view negative x value.
