Jonathon,
I don't see anything wrong with this (except you don't show how you
display a new "grass" in your exitframe). But here's an alternative
behavior that rotates through 3 castmembers which must be in
consecutive positions in a castlib. It assumes that the first of the
3 is on stage at the beginning (which is what you are saying, I
think). This uses member numbers and offsets instead of names.
property pMemberBase
property pCurrentOffset
property spriteNum
on beginSprite me
pMemberBase = sprite(spriteNum).member.number
pCurrentOffset = 0
end
on exitframe
if sprite(spriteNum).locV <= 1890 then
return
end if
pCurrentOffset = pCurrentOffset + 1
if pCurrentOffset = 3 then
pCurrentOffset = 0
end if
sprite(spriteNum).member = pMemberBase + pCurrentOffset
end
