Routine: Switch

Collects large batches of if routines into one simple switch routine.

== Syntax

- 'switch[all] {first part of conditional}':
    - '{second part}':
        - 'your routines here'
    - '{different second part}':
        - 'more routines here'
    etc.

== Explanation The switch routine can be used to replace many nearly-identical if routines in a row with just one switch. The benefits of doing this are a little bit less repetition, and a small speed gain. To show why this happens, let's say you have the following switch:

- 'switch attacker.wielding':
    - 'WOOD_SWORD': '+3'
    - 'STONE_SWORD': '+5'
    - 'IRON_SWORD': '+7'
    - 'DIAMOND_SWORD': '+10'
    - 'GOLD_SWORD': '+10'
    - 'WOOD_AXE': '+2'
    - 'STONE_AXE': '+4'
    - 'IRON_AXE': '+8'
    - 'DIAMOND_AXE': '+11'
    - 'GOLD_AXE': '+7'
    - 'BOW': '+10'                                                     
    - 'AIR': '+1'
    - 'SAND': '+1'
    - 'CACTUS': '+1'
    - 'GRAVEL': '+1'
    - 'WOOD': '+1'
    - 'SANDSTONE': '+1'
    - 'WHEAT': '+1'
    - 'APPLE': '+1'
    - 'RAW_FISH': '+1'
    - 'STRING': '+1'
    - 'COAL': '+1'
    - 'STICK': '+1'
    - 'WOOD_SWORD': '+1'
    - 'STONE_SWORD': '+2'
    - 'IRON_SWORD': '+3'
    - 'DIAMOND_SWORD': '+6'
    - 'GOLD_SWORD': '+15'
    - 'WOOD_AXE': '+3'
    - 'STONE_AXE': '+4'
    - 'IRON_AXE': '+6'
    - 'DIAMOND_AXE': '+11'
    - 'GOLD_AXE': '+28'

This has a whopping 34 different items it checks for. If this were a bunch of if statements, MD would have to go through, one by one and check each one. If you were wielding a wooden sword for instance, it would match the first one, then still have to go through all 33 remaining routines essentially wasting its time. A switch statement, however, stops checking after the first one it found. This isn't a huge improvement, but it might be noticeable and worth it if your config is 1.1 MB large and full of these situations.

== Examples Say you have something like this in your Damage event:

Since no entity can ever be wielding two things at once, only one of the attacker.wielding groups will be fired at once. This will be much better as a few switch routines:
