can't place the sprites

[mehguy]

I tried writing the sprite x and y coordination, it wouldn't let me run it.

 

playfield:

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

................................

................................

................................

................................

................................

................................

................................

................................

................................

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

end

COLUBK = $9C

COLUPF = $58

player0x=50:player0y=50

NUSIZ0 = 16

sprites

player0:

%00101000

%00101000

%01111100

%01111100

%01111100

%00111000

%00101000

%00010000

end

loop

drawscreen

goto loop

It looks like this line:

 

player0x=50:player0y=50

 

Might be missing its leading space?

 

Alternately, try including all those declarations within the loop and see if that helps. Some kernels can be finicky about not putting declarations in the drawing loop.

The forum mangles code formatting but it's worth mentioning..

 

Always double check that the ONLY lines that have no spaces at the beginning are labels and "end" (as in, ending playfield or sprite data).

not sure what your problem is

this works

 playfield:
 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
 ................................
 ................................
 ................................
 ................................
 ................................
 ................................
 ................................
 ................................
 ................................
 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
end
 
 COLUBK = $9C
 COLUPF = $58
 player0x=50:player0y=50
 
 NUSIZ0 = 16
 
sprites

 player0:
 %00101000
 %00101000
 %01111100
 %01111100
 %01111100
 %00111000
 %00101000
 %00010000
end
 
 
 
loop
 drawscreen
 goto loop

sprites

Thanks. I forgot the space before the line.

Also, how would I go about making sprites not only a single color.

That website I linked to is a must. After I fire up VisualbB the VERY next thing I do is go there.

Ok it's either multicolored sprites or the missle...

Or you can use the DPC+ kernel and everything changes:

(Meaning you get multicolored sprites and you get to keep the missiles.)

I'm sure this is for the X value, but it's not specified so it might confuse newbies:

Player Graphics (DPC+)

...

Player1 only wraps because values larger than 165 cannot be supported, so to prevent crashes, DPC+ wraps automatically. It is up to the programmer to wrap player0, and the missiles and ball.

EDIT: nevermind, i figured it out
