Function Syntax
Halts all queued functions and the entire script it is called from. Often used for error-handling.
Code Sample
This code will abort the script if run by the "wrong" character.
if (my_name() != "MrPicky") {
abort("I don't want you to run this script, mister!");
}
An example of abort() used for error-handling.
float mass = 5.0;
float volume = some_function(); //where some_function() returns 0.0
float density;
if (volume_cf == 0) {
abort("Error: Division by zero requested.");
} else {
density = mass / volume;
}
CLI Equivalent
Also available as the CLI command "abort," which will not be queued (similarly stops execution of all remaining commands when parsed).
