The first part of this format details what the function returns; this value may be stored in an appropriate [[:Category:Variables|variable]] or used as a condition in an <tt>if</tt> statement or similar. If the function does not return any value, <tt>(void)</tt> is used; otherwise, the return value is split into two halves, separated by a colon (<tt>:</tt>). The first half is what the value signifies (often a game statistic, sometimes other things), while the second half is the type of the value: | The first part of this format details what the function returns; this value may be stored in an appropriate [[:Category:Variables|variable]] or used as a condition in an <tt>if</tt> statement or similar.
