Description

Description:
A non-existing Script or script that has finished (scriptDone). To compare non-existent scripts use isNull or isEqualTo:
scriptNull == scriptNull; // ERROR! == cannot be used with script object isNull scriptNull; // true scriptNull isEqualTo scriptNull; // true
Groups:
Variables

Syntax

Syntax:
scriptNull
Return Value:
Script - NULL script

Examples

Example 1:
Wait until previous script is finished before starting a new one:
[] spawn { _script = scriptNull; for "_i" from 1 to 10 do { waitUntil { isNull _script }; _script = _i spawn { hint format ["script %1 started", _this]; sleep 1; hint format ["script %1 finished", _this]; sleep 0.2; }; }; };
Example 2:
if (scriptDone (_obj getVariable ["objScript", scriptNull])) then { _obj setVariable ["objScript", _obj spawn { waitUntil { damage _this > 0.9 }; hint "Critical Damage!"; }]; };
Example 3:
str scriptNull; // <NULL-script>
