Syntax

• copyarray <destination array>, <source array>, <amount of elements to copy>;

Description

This command copies a range of values from given source array to given destination array. If you specify an index for either or both, the data will be copied string from or to the given index.

If copying would add more than 128 elements to the destination array, the remaining elements are cut off. If a combination of index and amount of elements to copy go beyond the 127th element, empty values, 0 or "" depending on array type, are assumed.

Note, that destination array and source array can point to the same variable, where the indexes differ.

Avoid use of script command getarraysize for the third parameter, if the array in question contains empty values, otherwise copyarray might not copy as many elements, as intended.

Examples

cleararray @arrayl[0], 100, 6;  // { 100, 100, 100, 100, 100, 100 }
setarray @arrays[0], 200, 300, 400, 500;
copyarray @arrayl[2], @arrays, 4;

Copies the first 3 elements of @arrays to @arrayl starting at index 2, resulting in @arrayl being { 100, 100, 200, 300, 400, 100 }.

copyarray @array[0], @array[1], 99;  // assuming @array has 100 elements
set @array[99], 0;  // wipe last element

This shifts all elements inside @array by one towards index 0, effectively removing the first element.

setarray @array[0], 100, 200, 0, 300, 400, 500, 600;
copyarray @array[0], @array[1], getarraysize(@array)-1;  // hidden bug

Will result in @array being { 200, 0, 300, 400, 500, 500, 600 } rather than intended { 200, 0, 300, 400, 500, 600, 600 }, because getarraysize returns 6, instead of 7.
