DPC+ and pfpixel not working correctly?

[+Random Terrain]

I was using pfpixel to test something and I noticed that it didn't seem to be working right, so deleted everything I could to make this test program:

 

aa_dpc_test_2014y_02m_01d_0509t.bin

 

aa_dpc_test_2014y_02m_01d_0509t.bas

 

Move the guy around and when you move left or right, a loop should draw pfpixels on the screen about 32 high, but that's not what happens. On the lower part of the screen, only one is drawn, and higher up different heights are drawn depending on how high up you go.

 

Am I doing something wrong or is pfpixel messed up?

Your program has logic to skip the pfpixels loop if _Loop2>32, but you initialize _Loop2 as half of the player's Y.

 

Therefore when the playery>64, the pfpixels loop is skipped. Which is pretty much what you described as the problem.

 

Try doing something like this instead...

 

  _Loop1 = ((player0x-13)/4)-1
   _Loop2 = 0

__Right_Loop

   y=_Loop2+(player0y/2)
   pfpixel _Loop1 y on

I've also attached a pfpixels test, just for bonus points.

Damn, I'm dumb. I must have looked at my code 20 times but I couldn't see what was staring right at me. Thanks, it works now.
