Struggling to create a sprite in Batari basic

[Defender02]

Good afternoon,

I have recently downloaded Batari basic and Visual batari. I followed the tutorial by Tinkernut, among other tutorials. I know how to draw a background, change its color and so on, but I struggle with sprites. No matter which tutorial I follow, when I try to compile my code with sprites, it says "Syntax error". If I try to run it after that, it says "Could not locate default.bas.bin and couldn't recompile". I am really motivated to start programming Atari 2600 games, so I would really appreciate any help 

Kind regards

My code:

The error:

Get rid of the playerXXX:

 

It should be:

 player0:
 %00011000
 %00111100
 %01111110
 %01111110
 %01111110
 %11111111
 %01111110
 %00011000
end

[KevKelley]

Same for the player1. I assume the use of playerXXX was just to show an example of what to use without specifying player number.

Also be sure to visit this page:

And be sure to look at the Tinkernut World Deluxe example programs on this page:

I believe COLUPF=$212 is wrong, too. Try COLUPF=$21

 

You might use the attached and compare your code.

Goodmorning! Thank you to everyone for your answers  : )

Now it works and I created a simple game where an enemy comes from the left or the right and you have to shoot him. Nothing phenomenal obviously but I'm happy that it works
