switch do block

Parameters:

switch: Switch Type

Return Value:

Anything

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"]

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.

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

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: switch (true) do { case (_boolVar): {someCode}; case (unit1 distance unit2 > 5): {someCode}; };

BEWARE:
Sometimes, and I'm unsure why, numbers are treated differently (A2OA 1.63) with quote-wraps that worked
in earlier code now not working unless quote-wraps are removed, with otherwise identical code.
_number1 = (floor random 10) switch (_number1) do { case "0": { _vehicle setobjecttexture[0,"\mymodpath\textures\num1.paa"]; }; //etc };

this one below works, and the one above stopped working with 1.63
switch (_number1) do { case 0: { _vehicle setobjecttexture[0,"\mymodpath\textures\num1.paa"]; }; //etc };
