The text hides because of the blue thing, what we call backdrop.
To turn it off, simply use
backdrop off. You will see that the blue thing is gone, but you'll also see that if you rotate the object, the screen doesn't get updated correctly.
(Like in this example)
make object cube 1, 1
backdrop off
print "hello"
for i = 1 to 360
rotate object 1, i, 0, 0
next i
wait key
Which is ofcourse not always handy.
If you want to avoid this... Well, then you don't have much choice but using loops.
Example:
make object cube 1, 1
do
set cursor 0, 0
print "hello"
loop
wait key
Beside this, we usually use
sync on and
sync, to make the program run smoothly.
sync on
make object cube 1, 1
do
set cursor 0, 0
print "hello"
sync
loop
wait key
(You only see the effect when you have lower fps)
It's the programmer's life:
Have a problem, solve the problem, and have a new problem to solve.
