Description:

The HoldRightSpell allows for the caster to continuously cast a spell at an entity or block location while holding down right click, even despite targeting and line of sight.

Note: For reset-time values under 500, targeting is not maintained and the spell does not continuously cast.

Configuration:

Since 4.0 Beta 13 some of these options support dynamic values through numeric or string expressions.

Option	Description	Type	Default	Supports expressions
spell	Sub-spell to cast when holding right click. This spell must implement TargetedEntitySpell or TargetedLocationSpell.	String		false
target-entity	Whether the spell should target an entity.	Boolean	true	true
target-location	Whether the spell should target a block location.	Boolean	false	true
reset-time	Time it takes in milliseconds for the caster to be able to target another entity or location with the spell after releasing right click.	Integer	250	true
max-duration	Maximum duration that the spell can target an entity or location in seconds.	Float	0	true
max-distance	Maximum distance the caster can be from the target while holding down right click for spell to cast.	Float	0	true
