play field Multi-sprite kernel play fields

[piders7]

The title speaks for itself. I'm having trouble creating a play field in a multi-sprite kernel.

I code in the first half of the field, but it compiles into a confusing mess of play field blocks - no apparent rhyme or reason to it.

Can you post your code and binary?

 set kernel multisprite

 rem play field setup

setup_room_1

 playfield:
 XXXXXXXXXXXXXXXXX
 X................
 X................
 X................
 X................
 X................
 X................
 X................
 X................
 X................
 XXXXXXXXXXXXX....
end

 COLUPF=14

 rem play field loop

loop_room_1

 drawscreen

 goto loop_room_1

This code isn't a game, but rather a small snippet of code meant to test out multi-sprite kernels.

Oh, yeah. In case you're wondering, the code compiles into this.

Your Playfield is 17 characters wide. It can only be 16. Remove the last column and your playfield should display correctly.

Also COLUPF=14 should be COLUPF=$14 to display the correct color.

The playfield's 16 characters wide now, and the playfield's color is deliberate. It's still not working as intended. I want the playfield to look like this. How am I supposed to achieve a playfield like this on a multisprite kernel?

Try adding "pfheight=7" somewhere in your code.

 

There's a section on it at RT's site for more info.

Aha! Excellent! That did the trick. Thank you!
