Title: Help My Project Builds....but
Post by: JbOnE on September 10, 2005, 03:36:00 PM

from a quick glance it looks like it should be showing on screen - i myself never really went with using pretransformed matrices, but just cuz you don't see it - doesn't mean it's not there try using xray debug tool (it's in 5933), play with modes and see if the invisible triangle doesn't just miraculously appear after altering a setting. it's a really nice tool to use for just such a debug problem

add

CODE

g_pD3DDevice->Present(NULL, NULL, NULL, NULL);

to end of loop

ok please dont hurt me since i made this topic yesterday i figured i'd post my current problem

ok when i add those audio functions in my main loop it goes to a black screen when i launch my xbe and yes i know the includes above are for XACT but i've been experimenting all night with a way to play music and it seems my Direct Music isnt working i know somewhere i made a stupid mistake and the one who corrects my code will think im retarded but it's been a long night and im leaving this code to a proffesional to fix so i can learn from my mistakes
