Rakugo Variables Workaround

Problem

Now there is problem that you need to use GDScript to change those vars, as in RakuScript you can only overwrite them, but we working on it.

a = 10
a += 1 # and other mod operations doesn't work - error
a = 11 # works

Temporary Solution

It is temporary as we think that we fix this incontinence in near feature.

This example show solution on character variable eve.relationship but it can be used on any variable. For this to work first you crate script called Workarounds.gd extends from Node and add to singletons. To add it to singletons go to menu Project -> Project Settings, then to Autoload tab and add Workarounds.gd to them.

This is Workarounds.gd script:

extends Node

## This example singleton make you able to use line `eve.relationship++10` in RakuScript
## using this line will add 10 to eve.relationship

func _ready():
  Rakugo.parser_add_regex_at_runtime("AdvanceEveRelationship", "^eve.relationship++<value>{NUMERIC}$")
  Rakugo.sg_custom_regex.connect(_on_custom_regex) # I just notice this line is missing in our docs

func _on_custom_regex(key:String, result:RegExMatch):
  if key == "AdvanceEveRelationship":
    var eva_relationship = Rakugo.get_variable("eva.relationship")
    Rakugo.set_variable("eva.relationship", eva_relationship + float(result.get_string(value)))
