This function creates an array of the given size. For each element in the new array, it calls the given callback function, and applies the return value to that element.
Using this function you can initialise the array with values that change depending on the array index.
Callback functionCallback function
The callback function supplied in the second argument should take 1 argument, which is the index of the current array element. It can return any type of value, which is stored in the array at that index.
function(index);
| Argument | Type | Description |
|---|---|---|
| index | Real | The current array index |
array_create_ext(size, function);
| Argument | Type | Description |
|---|---|---|
| size | Real | The size of the array |
| function | Function | The callback function used to initialise each entry |
var _f = function(_index)
{
return _index + 1;
}
array = array_create_ext(100, _f);
show_debug_message(array);
The above code first creates a temporary function _f that takes in an index as an argument, and returns that index with 1 added to it.
It then uses array_create_ext with the _f function which creates an array filled with the integer numbers from 1 to 100.
