ord

This function takes a single character input string and returns the Unicode (UTF8) value for that character. Note that when used with the keyboard_check* functions, the input string can only be one character in length and can only be a number from 0 to 9 or a capitalised Roman character from A to Z.

Syntax:

ord(string);

Returns:

Real

Example:

if (keyboard_check(ord("W")))
{
    y -= 4;
}

This will move the calling instance four pixels upwards if the key W is held down.
