How to take control over sprites

[aka]

Hi

I have been studying the source code for Galaxian and this small game made by RedAngel to get an idea of how to make simple games

topic and source code posted here
devster.proboards22.com/index.cgi?board=basiegaxorz&action=display&thread=1110995489

And I'm still alitte confused on how to move the ship sprite with my keyboard...............

Can someone explain the different ways that I can move my sprite [sprites] what I mean is in some games I what to use all dierctions and A,B and C buttons and in others I what to scroll left and right like in Galaxian and shot with the A button...............

Here's the source code

pallettes pallette1,0,0,15
loadtiles sprites,1,64
ship=addsprite(1,1)
propsprite ship,64,0
movesprite ship,128,128
joypad:
j=joypad()
if j.2 then shiftsprite ship,1,0
if j.3 then shiftsprite ship,-1,0
sprites:
DATALONG $00033000 '1:ship
DATALONG $00033000
DATALONG $00355300
DATALONG $30311303
DATALONG $30311303
DATALONG $33522533
DATALONG $35244253
DATALONG $00000000
pallette1: DATAINT $0000,$0E22,$0AAA,$0444,$0EA0,$0888,$0000,$0000
          DATAINT $0000,$0000,$0000,$0000,$0000,$0000,$0000,$0000



But this had no effect on the sprite

Any help is appreciated ;D ;D

Thanks

I figured it out here's the new code ;D

pallettes pallette1,0,0,15
loadtiles sprites,1,64
ship=addsprite(1,1)
propsprite ship,64,0
movesprite ship,286,340  
while 1
shiftsprite ship,0,0  
sleep 1
joypad:
j=joypad()
if j.2 then shiftsprite ship,-3,0
if j.3 then shiftsprite ship,3,0
if j.0 then shiftsprite ship,0,-3
if j.1 then shiftsprite ship,0,3

sprites:
DATALONG $00033000 '1:ship
DATALONG $00033000
DATALONG $00355300
DATALONG $30311303
DATALONG $30311303
DATALONG $33522533
DATALONG $35244253
DATALONG $00000000
pallette1: DATAINT $0000,$0E22,$0AAA,$0444,$0EA0,$0888,$0000,$0000
          DATAINT $0000,$0000,$0000,$0000,$0000,$0000,$0000,$0000

wend

I am very happy now ;D ;D ;D

Peace
