switch (roll option)

[switch():] Roll Option

* Introduced in version 1.3b46

Chooses among several options and executes code based on the expression.

Usage

[switch(expression):
   case case1: body1;
   case case2: body2;
   default: defaultBody
]

Parameters

• expression - The regular expression that determines which case is executed. Since this is a regular expression, metacharacters such as * and () will need to have backslashes in front of them if you want to match them literally.
• case - A potential match for the expression, possesses a corresponding body that is executed if a match is made.
• default - If the expression finds no matches within the cases, then the defaultBody is executed.

Notes

• the case and default statements are the only case-sensitive statements in MapTool, thus CASE or Default will NOT work!
• strings in the case MUST be surrounded by "double quotes" as 'single quotes' will generate an error.

Examples

[h:powerType="at-will"]
[switch(powerType):
case "at-will": "You may use this power as much as you like";
case "encounter": "You may only use this power once per encounter";
case "daily": "You may only use this power once per day"]

Outputs:

You may use this power as much as you like

[h:powerType=".*sword.*"]
[switch(powerType):
case "flail": "one-handed weapon; two-handed does Str*2 damage";
case "shortsword": "used for jabs, so is a puncturing weapon";
case "longsword": "a slashing weapon"]

Outputs:

used for jabs, so is a puncturing weapon

Notice that the first matching clause was the one that the [switch():] option found.

When using the [code():] option with a switch option, each case body has its own set of braces, like so:

[h,switch(class),code:
case "Warrior": {
  [Armor = 6]
  [beginningPowers = "Sword, Shield Bash, Bow, Shield, Torch"]
};
case "Rogue": {
  [Armor = 2]
  [beginningPowers = "Dagger, Hide, Backstab, Pick Lock, Torch"]
};
case "Wizard": {
  [Armor = 1]
  [beginningPowers = "Dagger, Staff, Light, Lightning Bolt, Fire Ball"]
};
case "Priest": {
  [Armor = 4]
  [beginningPowers = "Mace, Heal, Protect, Banish Undead, Torch"]
};
default: {
  [Armor = 0]
  [beginningPowers = "Fists, Feet"]
}]
