LL Functions

This category contains built-in LSL functions.

Mutability

All types in LSL are immutable (they can't be mutated by side effect), variables can only be changed by being overwritten. There is no way to modify a variable's value indirectly; the only way is through direct interaction with a storing operator (=, +=, -=, *=, /=, %=, ++, --).

• Built-in functions will never modify the variables used as parameters.
• User functions that change the values of parameters inside the function scope will not have those changes applied to the variables that supplied those parameters.
