Graphics / Re: Drawing to a sf::RenderTexture on separate thread

« on: January 20, 2016, 05:40:32 pm »

I understand that it is difficult but I really want to use Qt for the menus since they are an important part of the game.

My solution is to start a new QThread with it's own sf::Window to show the game world and minimize the menu(-thread) while the game itself is active.

Graphics / [Solved] Drawing to a sf::RenderTexture on separate thread

« on: January 18, 2016, 10:54:31 pm »

Hey folks! I'm trying to create a game using sfml and Qt on Windows! I want to separate all the game logic and rendering to a separate QThread and draw the result on a canvas on the main gui-thread. I was hoping I could render the picture in a sf::RenderTexture and signal the texture using Qt:s signal/slot system to the gui-thread. However, the program always crashes with a segmentation fault when calling the sf::RenderTexture::getTexture() in the game-thread. Any ideas? Here's some debug-info:
