This is a very simple question, and I have no idea why it doesn't work. Could someone please help, because I am probably being really stupid?!

I have the following code in my program:

down_angle#=mousey()/screen height()
print down_angle#

This should give a decimal number between 0 and 1, depending on where the mouse is on the screen (I think), but all it returns from the print command is 0, wherever the mouse is.

Thanks, David

Try this code, it seems to work for me.



I believe it must be some issue with it being an interger divison with a fractional answer rounding down to zero.

Thanks for that, it works fine now. Maybe it is a bug, and I wonder whether it will get fixed.

It's not a bug - it's integer arithmetic at work again
