Description
- Description:
- Searches for an element within array for which the code evaluates to true.
Returns the zero-based index on success or -1 if not found.
Code on the right side of the command is evaluated for each element of the array, processed element can be referenced in code as _x. - Groups:
- Arrays
Syntax
- Syntax:
- array findIf code
- Parameters:
- array: Array - array to search in
- code: Code - code defining an element to find, processed element can be referenced within the code as _x
- Return Value:
- Number - Zero-based position of the first array element for which the code evaluate to true, -1 if not found
Examples
- Example 1:
[unit1, unit2, unit3] findIf {not alive _x}; // return index of the first dead unit)
- Example 2:
// two ways how to 'wait for all units to be dead': waitUntil { [unit1, unit2, unit3] findIf {alive _x} == -1 }; // fast, terminates as soon as it finds a living unit waitUntil { {alive _x} count [unit1, unit2, unit3] == 0 }; // slow, always goes through all array elements
