Be careful of the parenthesis around the variable you're switching on.  If you accidentally use braces instead (ex: switch {_myVar} do{...), it won't error, but will always return default.<br>

Using [[switch]] with strings is case-sensitive, (unlike string comparisons).

<dt class="note">'''[[User:General_Barron|General Barron]]'''<dd class="note">
To be safe about the case sensitivity issue, use the [[toLower]] or [[toUpper]] command to force all strings to a certain case.

It's possible to use [[Boolean]] value as a switch and [[Code]] as case. One thing to take special care in such case is that code must be in parentheses. Example:
<code>
switch (true) do
{
case (_boolVar): {someCode};
case (unit1 distance unit2 > 5): {someCode};
};
</code>
