 ====== Ternary operator in ACS ======
-[[ACC]] doesn't support the ternary operator '?:', but [[BCC]] and [[GDCC]] do.
+[[ACC]] doesn't support the ternary operator '?:', but [[BCC]] and [[GDCC]] do. To emulate it in ACC, ACSUtils implements the following trivial function:
-To emulate it in ACC, ACSUtils implements the following trivial function:
+''any cond(bool condition, any a, any b)''
-''any cond(bool condition, any whentrue, any whenfalse)''
+If ''condition'' is true, it returns a, otherwise it returns b.
-If ''condition'' is true, function returns ''whentrue'', otherwise it retuns ''whenfalse''.
 The only difference is that all arguments are evaluated before the function is called. This means that ''cond(x, f(), g())'' will call both ''f()'' and ''g()'', while ''x ? f() : g()'' will call only one of them.
+===== Examples =====
+Without ''cond()'':
+<code>
+int color = CR_RED;
+if (PlayerTeam() == TEAM_BLUE)
+    color = CR_BLUE;
+DrawSomething(color);
+</code>
+With ''cond()'':
+<code>
+DrawSomething(cond(PlayerTeam() == TEAM_BLUE, CR_BLUE, CR_RED));
+</code>
