Make your own buttons? There are two ways. The first is to check to see if the mouse is within a defined area by using greater and less than signs. The reason I don't say how to do that is because its: a)very hard, and b)never works. Instead, make your own cursor, like this:
load image "cursor.bmp",1
sprite 1,mousex(),mousey(),1
do
sprite 1,mousex(),mousey(),1
loop
Then, simply check for a mouseclick while the cursor sprite is overlapping the button sprite, like this:
load image "button.bmp",2
if mouseclick()=1 and sprite collision(1,2)=1
sleep 100
Hope that's what you wanted.
Gentlemen, your physics books were wrong. All of everything consists of two elements: me and the computer.
