+Random Terrain Posted July 20, 2017 Share Posted July 20, 2017 What is player0x? It's not a register. Is it a keyword? A variable? Or is it called something else? I'd like to know the official name for things like player0x, player1x, player0y, player1y, missile0x, missile1x, missile0y, and missile1y. Thanks.

RevEng Posted July 20, 2017 Share Posted July 20, 2017 It's a variable. If you want to differentiate them from the game's own variables, you could call them kernel variables. 1 Quote Link to comment Share on other sites More sharing options...

gauauu Posted July 28, 2017 Share Posted July 28, 2017 Is there a doc somewhere that explains how bb's special variables are laid out in memory? (Are player0x and player1x consecutive so I can access them as an array?) Quote Link to comment Share on other sites More sharing options...

(Are player0x and player1x consecutive so I can access them as an array?) it depends on the kernel they're defined in the header files see eg 2600basic.h 1 Quote Link to comment Share on other sites More sharing options...
