Array

An array is one of the types of TRIK Studio language that stores a set of values ​​(array elements) identified by index. The numbering of indices in the array starts at 0.

Arrays can be created explicitly using the following expressions (the next lines are equivalent):

a = {1; 2; 3; 4};
a = {1, 2, 3, 4};

Or with explicit indices:

a = {[0] = 1, [10] = 2, [20] = 3};

You can use arrays without creating them. For example, like this:

a[1] = 1;
a[2] = 2;

In this case, "empty spaces" in the array (indices that did not have an explicit assignment) will be filled with default values:

  • 0 — for real and integer;

  • false for boolean;

  • empty lines for arrays of strings.

Array values ​​can also be used without curly braces if used as the return value. For example, this expression will return an array of numbers 1 and 2:

a = 1;
b = 2;
a, b

This is implemented in order to interpret the enumerations of values ​​(for example, the ports of motors in the block "Motors forward") as arrays. Therefore, wherever you use a comma-separated value notation, you can use an array.
