Graphics / [SOLVED] Auto Movement

« on: July 27, 2013, 01:38:56 am »

First of all, I'm currently reading the SFML Game Development book, in the first chapter, when movement is introduced, I encountered some problems, I spawn a white circle in the centre of the window, now If i press any directional arrow, the circle keeps going in the other direction till I press it, and then it gets back to normal, and horizontal and vertical ones are seperate.

Example: I start "Game", press up, the circle keeps going down, i hold up, the circle stands still, I release, it keeps going down, I press down, it stops, now it responds normally to both keys, it will happen again with the right and left, it gets fixed after the initial error, but I wish to know how I can remove it

General / [SOLVED] Configuration Problem

« on: July 06, 2013, 07:34:02 am »

I'm using VS 11 and was just following the SFML configuration tutorial, and at the end when I compile I get

"error lnk1112 module machine type 'x64' conflicts with target machine type 'x86' sfml"

 and I even tried go to linker > advanced > and change target machine, but that just changed their order, this is my linker input (just incase they are wrong, they look a bit wrong to me)

"sfml-system-s.lib;sfml-window-s.lib;sfml-graphics-s.lib;sfml-network-s.lib;sfml-audio-s.lib;sfml-system-s-d.lib;sfml-window-s-d.lib;sfml-graphics-s-d.lib;sfml-network-s-d.lib;sfml-audio-s-d.lib;%(AdditionalDependencies)"

and this is my c++ preprocessor

"SFML_STATIC;WIN32;_DEBUG;_CONSOLE;%(PreprocessorDefinitions)"

Can someone help?
