Math do not support writing var to item

[GuardianDll]

Is your feature request related to a problem? Please describe.

As title says, trying to write n_ value when beta talker is item, and then read the written value, result in returning null instead of the written value. It seems the functionality works only within u_add_var?

Solution you would like.

Being able to write val to item using math

Describe alternatives you have considered.

Gonna make an example eoc later

So my testing seems to show items can do vars. This json is what I used

{
    "id": "test",
    "type": "TOOL",
    "name": { "str": "test" },
    "description": "A generic inflatable abstract to use for specific items.",
    "weight": "3 kg",
    "volume": "5 L",
    "price": 5000,
    "material": [ "plastic" ],
    "symbol": "P",
    "color": "light_red",    
    "use_action": { "type": "cast_spell", "spell_id": "test", "no_fail": true, "level": 1 }
  },
  {
    "type": "effect_on_condition",
    "id": "EOC_TEST",
    "condition": { "math": [ "n_test", "<", "2" ] },
    "effect": { "math": [ "n_test", "++" ] },
    "false_effect": {
      "npc_spawn_npc": "portal_person",
      "hallucination_count": 2,
      "min_radius": 3,
      "max_radius": 5,
      "lifespan": [ "1 minutes", "3 minutes" ],
      "spawn_message": "A person steps nearby from somewhere else.",
      "spawn_message_plural": "Several identical people walk nearby from nowhere."
    }
  },
  {
    "type": "SPELL",
    "id": "test",
    "name": { "str": "Base characteristics of portal spells" },
    "description": "Base portal stats.",
    "valid_targets": [ "ground" ],
    "max_level": 1,
    "base_casting_time": 75,
    "min_range": 1,
    "max_range": 1,
    "shape": "blast",
    "effect": "effect_on_condition",
    "effect_str": "EOC_TEST"
  },

If you have an example of it failing I'm happy to take another look.

Needs an example where it fails. There's nothing special on math's side and the var-writing behaviour is handled by the talker implementation.

Are you perhaps trying to write a var with math and then access it in code, or the other way around? That will not work directly because dialogue variables are always pefixed by npctalk_var_, something that I intended to remove eventually.

apparently something was wrong with my previous setup - using this clearly shows that the value is stored and read properly

  {
    "id": "qwerty_test",
    "type": "TOOL",
    "name": { "str": "qwerty_test" },
    "description": "qwerty_test",
    "weight": "1 g",
    "volume": "1 ml",
    "symbol": "F",
    "use_action": [ { "type": "effect_on_conditions", "description": "Write value", "effect_on_conditions": [ "TEST_EOC_1" ] } ]
  },
  {
    "type": "effect_on_condition",
    "id": "TEST_EOC_1",
    "effect": [ { "math": [ "n_test_val", "=", "rand(100)" ] }, { "run_eocs": [ "TEST_EOC_2" ] } ]
  },
  {
    "type": "effect_on_condition",
    "id": "TEST_EOC_2",
    "effect": [ { "u_message": "Random value: <npc_val:test_val>", "type": "good" } ]
  }
