Description:

Modifiers allow an action to take place when a condition is met upon a spell being cast. For example, spells can require a condition to pass to be cast successfully.

Source Code

Configuration:

There are two types of modifier configurations:

Single - Action done based on one condition.
Modifier collections - Action to do based on multiple conditions. A pass condition can be specified where you can decide if the collection passes when ALL conditions pass or if ANY of the listed conditions passing is enough for the whole collection to pass. XOR defines that the collection can pass only if one of the listed conditions passes.

You can take a closer look at modifier collections on this guide, but on this page, we will only cover modifiers that are paired with a condition and an action for the condition.

Modifiers are a general spell option that contains a list of strings. Each of these strings contains a modifier, a pair with one condition and one action. The format for a modifier can be seen below. What's specified in round brackets is always required, what's specified in square brackets is only required if the condition or action expects a var value - more about these variables will be covered on the Modifier Conditions and Modifier Actions pages.

`(condition) [condition var] (action) [action var]`

You can specify a string to be sent to the caster of the spell if all modifiers fail to cast using the option str-modifier-failed. You can also send a string if a specific modifier fails by separating the message from the modifier with $$. Here's an example:

modifiers:
    - onground require$$You must be on the ground to cast this spell!
    # Color code supported
    - day required$$&4It must be &6day &4for this spell to cast successfully.

If you prepend the character ! (and surround the modifier string in quotes because YAML will screech at you), the condition outcome would be inverted. Say your modifier is day require. An inverted version, a condition that would only pass if it's nighttime, could be day deny and night require, but it can also be "!day require".

You might ask what the point of this is. There is a modifier action castinstead (spell) that will cast a different specified spell if the condition passes. So you could have something like day castinstead setNight.

Some conditions do not have a dualistic sibling (e.g. night and day), an inverted version of the condition. Say you configured the modifier facing to cast a spell if you're facing west - you would use facing west castinstead (spell). Now, if you want this other spell to only be cast if the caster is not facing west but some other direction, you can use "!facing west castinstead (spell)".

Conditions:

Some conditions don't require a condition variable. If they do it will be specified throughout this documentation as "ConditionVar".

Condition	Description	ConditionVar	Has Entity Target	Has Location Target
