Suggestions for Game Rules

[BenCheung0422]

A new system of Game Rules has been proposed in #57. This discussion is opened for collecting the ideas and suggestions of Game Rules to be added to TerraModulus.

Scopes & Criteria

There are several criteria and constrains for setting a Game Rule:

• Should not overlap the roles and characteristics of a Resource Pack or a Data Pack.
• Are not a setting of World Generation.
• Should not modify the attributes of an Item, a Tile or an Entity, but
• Are allowed to affect the functionalities or effectiveness of the particular attributes.
• Could be but either a Boolean, a Numeric (ranged or not), or an Enum option.

Naming

The names of the Game Rules must be either an imperative sentence (starting with a bare infinitive) of an action or a noun of the name of the feature (may come from a verb), so to be concise, precise and descriptive enough about a particular Rule. In addition, using adverb would be preferentially avoided if possible. The Rules decorated with "do" in their names are preferentially Boolean while Boolean Rules preferentially use an imperative sentence; otherwise nouns are preferred.

Presets

There are several built-in presets serving as the default values for the Rules:

• Peaceful
• Easy
• Normal
• Hard
• Hardcore
• Ultra Hardcore
