Graphics / Re: Image.loadFromFile() not defined, other functions work fine. Linking problem?

« on: July 13, 2017, 02:39:51 pm »

Which IDE are you using?

It appears to be a linking problem. Can you show configuration of your project?

Which error message do you get? LoafFromFile error message looks like "failed to load image. Reason:

• ". Which 'reason' does it give to you?

Of if the main things, that you need to make, in order to have a good game, is story/lord/etc. (Well, until you're planning to make chess  )

Which functions are marked as undefined in particular?

No, SFML doesn't provide anything like that

First: don't remove event polling at any case, you may cause event queue overflow

Secondly: did you try to remove std::cout call? standard output operations may slow down your code a little bit. So, consider testing the code by using VS2015 debugger.

Window / Re: Failed to activate the window's context

« on: January 20, 2017, 05:55:51 pm »

I use visual studio 2015 community, so I won't have to compile SFML myself plus I get not bad user interface and it's free.

Well, window.create executes lots of commands, in short: window.create() is pretty expensive operation. Just looks at SFML/ source and you'll understand what I am taking about.

Try to build SFML yourself from source

Is your the compiler, with which SFML was built the exactly the same compiler as your? Did you install new drivers?

What do you mean under "detecting outside the window"?

Or! You can try to write a smiple one yourself...

Graphics / Re: how to apply antialiasingLevel to RenderTarget?

« on: November 24, 2016, 07:35:24 am »

The simplest solution to do this is writing the antialiasing shader and apply it on sf::Sprite, which uses sf::RenderTexture as its texture. Of course, if your rendering is simple and you render directly to the window, then you can set the antialising in context settings. To summarize, there is no way to apply default OpenGL antialising to any sf::RenderTarget(sf::Window and classes, which derive from or, are exceptions)

Graphics / Re: texture NOT updating from window

« on: November 05, 2016, 03:44:53 pm »

I know the reason why this happens:
 SFML window is always double buffered, what does it mean? You draw to the back buffer and then swap it with read buffer(window.display() does the swapping).

What is thiat code doing(rather fragment of code)? Let's imagine, that "a" the first buffer and "b" the second buffer. Then we can describe code's work with following list of actions:
1.) write some stuff to "a"
2.) swap "a" with "b". Now all operations such as "draw" and "read screen" are now operating on "b".
3.) try to read data from "b", which contains previous rendered frame.

You are probably linking debug libs(the ones -d suffix) in release or release libs in debug(without -d suffix).
