Examples

Example 1:

switch (_a) do { case 1 : { /*...code...*/ }; case 2 : { /*...code...*/ }; default { /*...code...*/ }; };

switch (_condition) do {
    case 1: { hint "1" };
    case 2: { hint "2" };
    default { hint "default" };
};

switch (_condition) do {
    case "string1";
    case "string2": { hint "string1 or string2" };
    case "string3";
    case "string4": { hint "string3 or string4" };
    default { hint "default" };
};

Example 2:

_color = switch (side player) do {
    case west: { "ColorGreen" };
    case east: { "ColorRed" };
};

Example 3:

_fn_moveForward = { /*...code...*/ };
_fn_moveBackward = { /*...code...*/ };
_fn_invalidKey = { /*...code...*/ };
switch true do {
    case (_dikCode in actionKeys "MoveForward"): _fn_moveForward;
    case (_dikCode in actionKeys "MoveBackward"): _fn_moveBackward;
    default _fn_invalidKey;
};

Example 4:

switch _var do {
    case "0";
    default { hint str ["default", _var] };
    case "3": { hint str ["3", _var] };
    case "1";
    case "4";
    case "2": { hint str ["2", _var] };
};

_var = "0"; //-> ["3", "0"]
_var = "1"; //-> ["2", "1"]
_var = "2"; //-> ["2", "2"]
_var = "3"; //-> ["3", "3"]
_var = "4"; //-> ["2", "4"]
_var = "5"; //-> ["default", "5"]

ColonelSandersLite: 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.; Posted on 06 Oct, 2009
Iva: 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: switch (true) do { case (_boolVar): {someCode}; case (unit1 distance unit2 > 5): {someCode}; };

Freddo3000: You are able to call code within the switch statements, such as: _myFunc = { systemChat "0"; case 1: {systemChat "1"}; systemChat "2"; }; _myParameter = 1; switch (_myParameter) do { _myParameter call _myFunc; case 1: {systemChat "4"}; systemChat "3"; default {systemChat "-1";}; }; However the order in which it is executed is difficult to make sense of, see the code comment.
