Hi,
I've been having some problems with get_mouse() and if-then loops. =
It seems that at the begining I need the variable assinged to =
get_mouse() to be an atom, then to change to a sequence. Here's the =
prog:
object event
event=3D-1
procedure mouseaction()
while event=3D-1 do
event=3Dget_mouse()
if sequence(event) then
if and_bits(event[1], 2) then --2's left down
display_image({300,420},ufire2[2])
end if
end if
end while
end procedure
mouseaction()
Can you help me out? Also, what exactly does and_bits do here? I had =
to get it from the HTML documentation to get the mouse action to =
work----I understand the rest, just not this.
Thanks
Thomas
