Sets a local or global variable to a specified value. This value can be a number or an expression.
Arithmetic Operators:
| Operator | Description |
|---|---|
| + | Addition |
| - | Subtraction |
| * | Multiplication |
| / | Division |
| % | Modulus (do integer division and return remainder) |
In integer divisions the remainder is truncated at the end of the operation:
set a to 9/5 will set a to 1
set a to 10*9/5 will set a to 18
Examples:
set a to 2
set b to a*a
set c to (b - a)*b - a
set d to ((3* -b+a) - c)/ -2
message "a=%.0f, b=%.0f, c=%.0f, d=%.0f" a b c d ; ("a=2, b=4, c=6, d=8")
set stage to getstage quest1 + 10
As you see, when you put a minus right in front of a variable the variable will be negated. To acomplish this, the parser needs you to put spaces around all minuses that are operators and not algebraic signs. If you use "b-a" in the above example, the script doesn't compile; it needs to be "b - a".
