Lesson 20 help

[Renthal97]

So I've been on this lesson for a good 4 hours about. Everything works perfectly aside aside from the fact that there is no animation occurring. It compiles and displays a still image on the screen as if there were no animation coding at all. I've watched the animation portion of the video countless times and I can't seem to figure out what I did wrong. It's not letting me attach any files though... It's not letting me attach a folder and it's giving me errors when I try to attach an individual file.

Got the zip file up.

For some reason after you increment the frame number you've used the bitwise AND assignment operator on it with DUDENFRAMES, this resets it to 0 every frame.

Code: Select all

void Game::Go()
{
	frameNumber++;
	frameNumber &= DUDENFRAMES; <--------HERE
	gfx.BeginFrame();
	ComposeFrame();
	gfx.EndFrame();
}

You should be testing if its greater than or equal to the total number of frames and then reset to 0 if it is.

Code: Select all

void Game::Go()
{
	frameNumber++;
	if( frameNumber >= DUDENFRAMES )
	{
		frameNumber = 0;
	}
	gfx.BeginFrame();
	ComposeFrame();
	gfx.EndFrame();
}

Thank you very much Musi for pointing that out for me. Really appreciate the help!
