Unary

Unary operators take one argument. In LSL these arguments are normally integers.


Operator Type Meaning Return Value Effect
variable++ Arithmetic post-increment variable variable is set to variable + 1
++variable Arithmetic pre-increment variable + 1 variable is set to variable + 1
variable-- Arithmetic post-decrement variable variable is set to variable - 1
--variable Arithmetic pre-decrement variable - 1 variable is set to variable - 1
!variable Logical Logical NOT 1 if variable is 0, otherwise 0 None
-variable Arithmetic Unary negation negative value of variable None
~variable Bitwise Bitwise NOT flips each bit of variable None

Examples:

integer x = 5;
llSay(0, (string)(x++));
//Says "5" and x is set to 6
integer x = 5;
llSay(0, (string)(++x));
//Says "6" and x is set to 6
