It's true. Here I'll make some code up real fast:
sync on
sync rate 0
make object sphere 1,25
do
yrotate camera wrapvalue(camera angle y()+mousemovex() )
if mouseclick() then move camera 10
x= object screen x(1):y=object screen y(1)
text x,y,"Here's the object?"
sync
loop
You'll notice the text at what should be the x and y coords of the object also appear if you turn around 180 degrees. It makes it less useful than it would be if it didn't wrap like that.
What's even worse is that if you say
sync on
sync rate 0
make object sphere 1,25
do
yrotate camera wrapvalue(camera angle y()+mousemovex() )
if mouseclick() then move camera 10
x= object screen x(1):y=object screen y(1)
if object in screen(1) then text x,y,"Here's the object?"
sync
loop
The words still appear for a moment even though the object is long gone from the screen. This makes it tough for me to do a perfect lense flare function.
