171.100.59.30: /* The JSON Data Format */

The long-term goal of Hack/Mine is to be thoroughly customizable, such that users can create their own content and share it with the community. As of version 0.6.4, this is starting to become a reality, as users can create their own spells via [[Spellscript]] and create their own classes and skill-sets through a configuration file (''hsmConfig.JSON'') located in the ''<.minecraft>/spells/'' directory. This information propagates over the network automatically, meaning each Hack/Mine server can offer its own unique RPG experience.

You'll definitely want to use a syntax-highlighted text editor like [http://www.sublimetext.com/ Sublime Text] when customizing Hack/Mine. A Sublime package for [[Spellscript]] is also available [http://www.mediafire.com/download.php?foak1j6b381huzz here].

This web site really has all the information and facts I wanted about this subject and didn't know who to ask. cacadeaafkgfcddd

==hsmConfig Layout==
At the highest level, ''hsmConfig'' is an object with several expected objects within it, including "classes" and "spells". Every object within the "classes" object will be added to Hack/Mine as a selectable class, whereas every object within "spells" will be added to the set of all possible spells that classes may have assigned to them. A description of all possible pairs for objects contained by ''classes'' and ''spells'' is now given.

Note: "LString" and "Script" refer to a strings that, if beginning '@', will be used to retrieve a value from the user's selected language files, or a script from the ''spells'' directory, respectively. Also, "Number" refers to any real number, whereas "Integer" refers to an integer. "Boolean" refers to values of either ''true'' or ''false''. "Map" refers to an object. And finally, note that block and item IDs should be [[Block and Item IDs|display IDs]], which are consistent with the vanilla Minecraft IDs but differ from the ones you'd be using within [[Spellscript]].

===Class===
To add a class to H/M, add a pair ''<className> : <classObject>'' to the classes object. <classObject> may consist of the following pairs:
{| class="wikitable"
! Key || Type || Description
|-
| "climbableBlocks" || Array of Integers || A list of block IDs that the player may freely climb, much like a ladder.
|-
| "description" || LString || The flavor-text presented on the character-rolling GUI when the class is moused over.
|-
| "displayColor" || String || The hexcode for the class's color, used through various GUIs for flavor. Should be formatted ''RRGGBB''.
|-
| "healthPerFortitude" || Integer || How much health the player receives per point of fortitude (default is 10).
|-
| "relativeIndex" || Number || Must be non-negative. Used to decide in what order to present the classes on GUIs.
|-
| "startingItems" || Array of Integers or Strings || A list of itemIDs that the player receives when the class is selected. A stack of multiple items may be specified by appending a ':' followed by the desired stack size (e.g. "20:64" is a stack of 64 glass).
|-
| "startingSpells" || Array of Strings || A list of spells, referenced from the ''spells'' object by name, that the player begins with.
|}

===Spell===
To add a spell to H/M, add a pair ''<spellName> : <spellObject>'' to the spells object. You'll also need to reference it from a class under the classes object via the "startingSpells" key (Additional methods of incorporating spells, such as in a talent tree, are planned.) <spellObject> may consist of the following pairs:
{| class="wikitable"
! Key || Type || Description
|-
| "activeManaCost" || Number || The base mana required each tick the spell is cast.
|-
| "activeManaCostPerStat" || Number || The additional mana required per stat each tick the spell is cast (see "stat").
|-
| "activeScript" || Script || The script to execute each tick the spell is being cast.
|-
| "activeScriptParams" || Map of Strings || Supplies custom parameters to the activeScript (see Custom Parameters below).
|-
| "coolDown" || Integer || The number of ticks before the spell may be cast again.
|-
| "delayCast" || Boolean || If true, does not expend the initial mana cost or begin the cool down when initially cast, on the assumption the Spellscript method ''SpellInstance.delayedCast'' will be called from within "effectScript" later.
|-
| "description" || LString || The description of the spell provided in its mouseover tooltip.
|-
| "displayName" || LString || The name of the spell as presented throughout various GUIs.
|-
| "effectScript" || Script || The script to execute when the spell is first cast.
|-
| "effectScriptParams" || Map of Strings || Supplies custom parameters to the effectScript (see Custom Parameters below).
|-
| "manaCost" || Number || The base mana required to initially cast the spell.
|-
| "manaCostPerStat" || Number || The additional mana required per stat to initially cast the spell (see "stat").
|-
| "stat" || String || The stat used to calculate additional initial or active mana cost. Case-insensitive, may be "str", "strength", "dex", etc.
|-
| "textureID" || Integer || The texture index of the icon to use for the spell in various GUIs (calculated as ''x + y * 16'')
|}

==Script Files==
Script files can be placed in and referenced from the ''spells'' directory, and are interpreted as [[Spellscript]] scripts. For both "activeScript" and "effectScript", a return type of ''bool'' is expected, indicating whether the spell is successfully cast. The scripts also have the following variables in scope:
{|class="wikitable"
! Type || Name || Description
|-
| World || world || The world (e.g. the Surface, the Nether, the End) in which the spell is being cast.
|-
| SpellInstance || spellInstance || The instance of the spell being cast.
|-
| Living || caster || The Living casting the spell (most likely a Player)
|-
| Entity || targetEntity || ("effectScript" only) The Entity the spell is cast on, if any.
|-
| Block || targetBlock || ("effectScript" only) The Block the spell is cast on, if any.
|}

===Custom Parameters===
Custom parameters are a way of making your script files easily configurable and reusable. Rather than hard-coding particular values into your script files (for example, the strength of a jump technique), you can insert identifiers surrounded by double exclamation marks in their place (for example, !!JUMP_STRENGTH!!). Then, whenever one of those scripts is referenced in ''hsmConfig'', you would also define an object of custom parameters, like:
<nowiki>"mySpell": {
"effectScript": "@spell_jump.ss",
"effectScriptParams": { "JUMP_STRENGTH": "3.2" }
}</nowiki>

Now for the spell mySpell, !!JUMP_STRENGTH!! will be replaced by the string specified in ''hsmConfig''! Pretty cool, eh?

Since it's simple string replacement, you can replace custom parameters with whatever snippets of code you desire. Suppose you wanted JUMP_STRENGTH to depend on strength in one spell, and dexterity in another-- you could do something like this:
<nowiki>"mySpell": {
"effectScript": "@spell_jump.ss",
"effectScriptParams": { "JUMP_STRENGTH": "3 + caster.getStr() * .02" }
},
"anotherSpell": {
"effectScript": "@spell_jump.ss",
"effectScriptParams": { "JUMP_STRENGTH": "3 + caster.getDex() * .02" }
}</nowiki>

Don't get too crazy though-- you want to be able to glance at a custom parameter's name and value and know exactly what it does, and depending on variables defined in another file can detract from this.
