Hi. I have little problem in functions with ahk. In e.x i want to make function to store var data and be accesible on main script.
I.E:
| Code: | add(2, 2)
msgbox, %answer%
Add(x, y)
{
answer := x + y
} |
After this answer is still blank, i want that answer would be = 4.  |

the variable answer isn't global, meaning the variable doesn't exist out side of the function.
One option:
| Code: | msgbox, % add(2,2)
Add(x, y)
{
return x+y
} |
Or you could make the variable global
| Code: | add(2,2)
msgbox, %answer%
Add(2,2)
{
Global answer
answer := x+y
} |
