The bB kernel automatically changes COLUP0 and COLUP1 to the scorecolor when it draws the score at the bottom of each frame.

 

Therefore you need to set COLUP0 and COLUP1 inside your loop so they get (re)set for each new frame.

 

If you haven't set the scorecolor, it will be black.

  COLUBK = $06 : rem * gray

if you're using player0color and player1color, you should be able to do the following and have it work:

 

player0color:
 66 
 66
 66
 66
end

 

te number of colors you put in player0color is how many pixels high your character is.

SeaGtGruff already gave the proper answer but I'd like to add it's a good idea to create your own draw event section to take care of this kind of stuff.

 

In my Nitebear on Sleepystreet game I've got the housekeeping in my own draw event section as such:

 

draw_event
rem If scrolling variable is set to true and the first bit of the counter is 1 then scroll the screen down
if scrolling && counter{0} then pfscroll down
rem If the march counter is toggled then flip the sprites around to look like they're animated
if march then REFP0 = 8 : REFP1 = 8
rem Since I change Nitebears color depending on his hit points I've got that wrapped up in a separate subroutine
gosub paint_nitebear
rem BatariBASIC forgets the sprite colors every drawsceen so set them to the current enemy size and color variables 
COLUP1 = enemycolor
NUSIZ1 = enemysize
rem Now that everything is set draw that screen![/color]
drawscreen

paint_nitebear
rem Depending on how low the hit points are set the player color via constants to make color codes more understandable
if nitebearhp > 50 then COLUP0 = c_tan : return
if nitebearhp > 25 then COLUP0 = c_orange : return
if nitebearhp > 10 then COLUP0 = c_red
return

here is my code, can someone just tell me what to put in it to add color to it?

oops, i also forgot to delete the line "if collision(player1,ball) then score=score+0:player1x=rand/2:player1y=0:bally=255" so don't mind that, i was experimenting, and figured out how to drop an item when you fire

One problem is the "scorecolor" statement, which has nothing after the "=" sign.

 

You need to add a "COLUP0" and a "COLUP1" statement to set the player colors. You could put them anywhere between the "sprites" label and the "drawscreen" statement, since the "sprites" label is the beginning of the main screen display loop.

 

Note that if you aren't going to be updating the player graphics, you can move the "player0:" and "player1:" statements out of the loop, above the "sprites" label, because the pointers to the player graphics will retain their values until you set them to something else, so you don't need to keep redefining the player graphics every time you go through the loop.

 

Likewise, you can move the "playfield:" statement above the "titlescreen" label, because you don't need to keep redefining the playfield each time through the loop.

 

Another issue I just noticed is the "drawscreen" statement in the "titlescreen" routine needs to be indented.

and one more question, how do i get the playfield in the titlescreen loop to display what it shows? it just gives me a black screen instead of the big "DJ!" in there

[esplonky]

nevermind, i figured it out!
