Updating the sprite and show it works for few seconds
« on: May 28, 2019, 07:42:31 pm »
Hi everyone!
i'm a very newbie with SFML, in trying to learn how to display my pixels array and refreshing window when needed. I've make this very basic program, it works, make me change the intesity of blue (whitch fill the window) based on my input but it works just for 2 or 3 seconds! Then the window doesn't not respond and freeze.

I'm using CodeBlocks

(click to show/hide)

You need an event handler to process the events given to the window.

See the SFML examples.
This one in particular is a pretty good skeleton example:

And this one is a good example of how your event loop will probably look:

Thank you!! Does anyone have a "practical and fast" solution for the code i proposed?
I have to study a bit of SFML but for now the code i proposed is really the only (core) thing i need for my projects and games (the console prompt is coming a bit dull  ;D)
