displaying and animating UDG's on the spectrum

Post by Crayon21 »

I can enter the binary data well enough but how do I display it? I'm not talking about poking the data for the small ones either. Commodore allows you to show the sprite, the C128 has a sprite command. How do I do this on the spectrum?

Data bin (numbers) then what?

Yes Crayon,

Code: Select all

10 CLS:LET u1=PEEK 23675+256*PEEK 23676
20 LET u2=10000:PRINT u2-INT(u2/256)*256
30 POKE 23675,u2-INT(u2/256)*256:POKE 23676,INT(u2/256)
40 PRINT AT 0,0;"\a\b\c\d\e\f\g\h\i\j\k\l\m\n\o\p\q\r\s\t\u";AT 5,5;u2
50 IF INKEY$="" THEN GO TO 50
60 LET u2=u2+8
70 GO TO 30
To enter UDG:

Code: Select all

9940 REM ***********************
9945 RESTORE 9940:FOR a=USR"a" TO USR"a"+7:READ b:POKE a,b:NEXT a:DATA 16,16,56,108,198,254,40,40
PRINT "\a"
Where \a = GRAPHICS +"a"

got the UDG on screen finally but what if I wanted to use a joystick (cursor keys in this case, I don't have an actual spectrum), how would I do that?

Hi Crayon,

Try to code a simple ZX81 like basic program based on the "PRIINT AT" command, it will work on the Spectrum.
Ever seen in your previous posts...

You only have to test for the keys 5678 and 0 for fire.
An external cursorjoystick works like that.
