SMILEBASIC

[Rabbit 2600]

Not sure if this is the right place, but I recently got my hands on Petite Computer for the 3DS an emulator for SMILEBASIC where you get to make your own software. I dabbled with BatariBasic so I figured somethings out but I need to ask a few questions to grasp somethings.

 

Anyway, my code so far allows for movement of an @ which is the player and an Z which would be a zombie.

 

My first question would be. How would I go about giving the zombie a random chance of moving towards the player if one of the buttons are pushed? I know how to make it move towards the player every time the buttons are pushed, I would need a random counter and I'm not sure on how to set them up. Like giving it a chance of 1 in 4.

X=5:Y=12

ZX=20:ZY=12

@LOOP

K=BUTTON(2)
IF K AND 1 THEN Y=Y-1
IF K AND 2 THEN Y=Y+1
IF K AND 4 THEN X=X-1
IF K AND 8 THEN X=X+1

LOCATE X,Y
?"@"

LOCATE ZX,ZY
?"Z"

VSYNC 1:CLS
GOTO @LOOP

Many thanks in advance =)
