View File Array manipulation functions This script provides various array manipulation functions, and more might be added in the future. All of those functions (except the arithmetic ones) work with both integer and string arrays. The start of the array is always implicitly index 0, unless an index is specified, ie @array[index] array_pad(<array>, <size>, <value>) pads the array left or right with <value> until it reaches <size> size. If <size> is negative it will pad left. > returns the number of added entries setarray(.@foo, 1, 2, 3, 4, 5); // initialize the array array_pad(.@foo, 8, 69); // => 3 // array is now: 1, 2, 3, 4, 5, 69, 69, 69 setarray(.@foo, 1, 2, 3, 4, 5);

Hello, I want to set a permanent character variable that calls from an array. For example, my variable set up: setarray(variable$[0], "value_1", "value_2", "value_3" ); And then call array to set the variable: variable$[2] = 1; It seems to work okay...but when scripts reload, values are cleared. Any help? Thanks.

Example Array = 1,2,3,4,5; if(Class == Swordman) Add value: 6,7,8; if(Baselevel > 90) Add value: 9,10; Final Array: 1,2,3,4,5,6,7,8,9,10;
