[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 theexpression, possesses a correspondingbodythat is executed if a match is made.default- If theexpressionfinds no matches within thecases, then thedefaultBodyis executed.
Notes
- the
caseanddefaultstatements are the only case-sensitive statements in MapTool, thusCASEorDefaultwill NOT work! - strings in the
caseMUST be surrounded by "double quotes" as 'single quotes' will generate an error. - do not put a
;after your last case.
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.
another example
[abort(input("number|0|enter a number"))]
[switch(number):
case 0: "you did not enter a number";
case 1: "you entered 1 as a number";
case 2: "you entered 2 as a number";
default: "you entered a number not equal to 1 or 2"
]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"]
}]
