Problem with hge and window 7
  • FraserFraser October 2009
    hello,

    I'm not sure if the problem I'm having is because I'm using windows 7 or not. Recently started to continue work on one of my projects with hge and when I load any textures I get the message "can't create texture" in the log.

    Has anyone experience this before or know what my problem is?


    Here's some code I wrote to test the problem, when I start the program I just get a white screen and the can't create texture message in the log.

    You can't call any graphics loading functions until after you call System_Initiate. The directx graphics device isn't created until that has been called.

    hmm... Just wondering, does HGE describe that anywhere? Like in the documentary? I can't remember reading it...

    Yes. Second paragraph in the Remarks section for HGE::System_Initiate.

    I'm using Visual C++ .NET2005 in developing this project, but the result is not like what i'm expect it just show a black screen with an orange box located in 100, 100 (probably), I also using Windows 7.

    i'm very confuse where did i do the wrong code, can you help me? htx in advanced :)

    Please edit your post and make sure to click the "Disable HTML in this post" checkbox. Otherwise, the forum tends to eat parts of your code. Right now, I can't tell what your code actually looks like.
  • jayaxidjayaxid July 2011
    hi prof,

    already clear after one night checking the whole code... just to add "\" in the filename...

    thx again prof...
  • ProfEclipseProfEclipse July 2011
    Glad you got it sorted out.

    As a tip for the future, you can use forward slashes instead of backslashes in file paths. That way you don't have to worry about double slashes. e.g.:

    "D:/menu.wav"

    instead of:

    "D:\\menu.wav"
