How does Draw.bas work?

[VGAGuy]

I am trying to make a game where you lay down bricks when you move forwards and pick them up when you move backwards.

I looked at the example program that almost does what I want but has a few problems:

 

1 It uses a playfield that is too big, I need the normal 31 X 11 playfield

 

2 I need it to draw behind the player not directly under the player

 

3 I need it to draw as fast as the player moves

 

I have tried to make the playfield smaller and disable the superchip, but if I do that I becomes a RAM editor.

 

 

 

Any Ideas on how to get this to work?

 

P.S. The code should come with the Bb compiler

I think the code for any game that anyone can think up should come with the bB compiler. batari was so lazy.

I meant draw.bas comes with Bb unless it is the newer version with 64k support as that did not have the file in the samples folder.

I wonder if there is anything here that you could adapt:

Double-click Draw: RT Version 01

Here's my bad attempt at adapting the code to my program.

At least it isn't a RAM editor like my previous attempts.

 

 

I am missing something but I can never figure out what.

 

 

EDIT: Got it working properly, thanks for the code.
