Help with Skip Draw

[j00sebox]

Hi I have been reading some tutorials on 2600 programming and I am trying to make a simple tag game. Right now I'm trying to get it so the player can move vertically by implementing skip draw. Sometimes when I start the ROM there is no sprite on the screen but other times there is one that I can control but it doesn't look like the sprite I want. 

 

Here is what my scan loop looks like:

 

This is my sprite data:

 

This is how I'm making the pointer:

 

Any help would be appreciated.

 

Thanks!

I guess my first thought would be that there's no way the player sprite would require 186 zero bytes followed by the sprite data!!

Most likely scenario is that you're probably miscalculating the pointer offset in your kernel.

I don't know the reason for the 186 zero bytes at the beginning of the sprite data, but there is another mistake in your SkipDraw code: you should use bcc skipDraw instead of bcs skipDraw.
