So I'm currently trying to make a little game that features some fish being generated in a random spot in a pond, then swimming back and forth. As a start I've just been trying to generate the fish and have them point in the direction they will be going first. The random location generation worked fine, but when I tried to add the fx to flip the fish in the direction it's heading, I get the error 'unexpected symbol near '='' But I've been looking for a while and can't see where the issue is. The error is flagging the 'o.x+=1 and o.fx=true' and 'o.x-=1 and o.fx=false' lines

This is the offending chunk of code, thank you for any guidance!

function initfish()

fish1={
sp=6,
x=40+rnd(60),
y=40+rnd(60),
fx=false
}

end

function fishmove(o)
waypicker=rnd(2)
if waypicker==1 then
direction="left"
elseif waypicker==2 then
direction="right"
end

if direction=="left" then
o.x-=1 and o.fx=false
elseif direction=="right" then
o.x+=1 and o.fx=true
end
end
end

function updatefish()
fishmove(fish1)

end

Why do you have the "and" in there? I would think it should be:

if direction=="left" then
  o.x-=1
  o.fx=false
elseif direction=="right" then
  o.x+=1
  o.fx=true
end

Thank you! this has resolved the error alongside removing some unneeded 'end's, but my flip still isn't working so I'll have to investigate further

My guess is that the problem is your rnd(2) call. That will do two things you probably don't want: return a non-integer number and return a value between 0 and 1.9999 (so never 2). To make that work, try this:

-- use flr() to get an int value, and add one to get 1 or 2 instead of 0 or 1
waypicker=flr(rnd(2)) + 1
