having trouble with key states

17 November 2012 - 01:01 PM

how do you input VK with two characters for example VK_LEFT_UP or something like that.

Direct x9 virtual key not working

30 September 2012 - 04:12 PM

This program is supposed to make a sonic sprite go left, right, up, down, and vertical but when i press the left to does no do anything then when i press right it does not go right but after i press them times ican go left and right then icant move until i press them again and it just repeats over and over. then when i press up it goes up it works but then if I press down it gose up and it just repeats and it just gose vertical at random i use an engine that i include that has a lot of files that it includes.Posted Image
