(pattonsteel) How to script custom trial spawners? | Denizen and Citizens | Page 1

Hello, I'm scripting a small dungeon instance, and would like to make use of the new trial spawners. I have generated the custom NBT for it:
trial_spawner[block_entity_data={id:"minecraft:trial_spawner",required_player_range:14,target_cooldown_length:3600,normal_config:{spawn_range:4,total_mobs:20,simultaneous_mobs:10,ticks_between_spawn:1,spawn_potentials:[{data:{entity:{id:"minecraft:zombie"}},weight:3},{data:{entity:{id:"minecraft:husk"}},weight:1}]},spawn_potentials:[{data:{entity:{id:"minecraft:zombie"}},weight:3},{data:{entity:{id:"minecraft:husk"}},weight:1}]}]

And using the /minecraft:give command, obtain a functional block.

I would like to be able to reset the field with Denizen, but have been reading that NBT is not meant to be supported(?) and am scratching my head with the -adjustblock usage vs. NBT

A finger ponting in the right direction would be super helpful! Thank you!

#

More on this, I've simply used setblock, but now I am running into the issue of not being able to find when the trial spawner has been defeated

#

I'm trying to find the data:cooldown_ends_at

#

or alternatively, the state of the spawner would work just as well

#

#

I know I can get material from a location tag, but how can I get the NBT?

this?

or i think that only gets denizen attributes

#

im not sure if there is sa way to get NBT for location/material

calm nest Apr 28, 2025, 11:52 PM

I'm getting unfilled from location[].property_map, and an empty list from location[].material.property_map

yeah

#

is there a way to bring a block up to an entity?

calm nest is there a way to bring a block up to an entity?

uh id imagine you can use make a block display with the material but thats like getting to something super hacky i feel like, and there might be a solution i just missed

#

what are you trying to do with the NBT??

well as I've been looking up and down, I noticed that we're supposed to be using methods for spawners like spawner_count, spawner_player_range, etc. but the trial spawners aren't responding to these methods "close match", but error

Did you mean to search for item_type?

since nbt is no longer a thing technically

zealous ferry !Mechanism itemtag.components_patch'

Mechanism: components_patch

(Property) Sets the item's internal component patch. That is, the changes in components on top of the item type's default components.
The map is in !language Raw NBT Encoding format.
This is mainly intended for item data persistence, and scripts should prefer using proper item properties instead of setting raw data directly.
If you're trying to control custom data (such as data set by other plugins), use !property ItemTag.custom_data.

ughh

#

maybe try that?

calm nest Apr 28, 2025, 11:58 PM

#

zealous ferry what are you trying to do with the NBT??

yeah lemme backup adn give you a better picture

zealous ferry Apr 28, 2025, 11:59 PM

also i do wonder if the regular spawner mechs work with the trial spawner?

calm nest Apr 29, 2025, 12:01 AM

#

I'm setting up a dungeon run using the new trail chambers, using the /minecraft:setblock to create spawners with custom parameters (link if curious). I am setting up exit conditions, including: player death, player exit, and all trial spawners defeated

I want to check the state of the spawner to see if the player has defeated all the mobs

I've tried a couple, but I don't think so

here, upon changing to a normal spawner from a trial spawner

zealous ferry Apr 29, 2025, 12:06 AM

#

huh interesting, this might be a feature request or a components patch thing

#

you might want to hear from someone else on this

calm nest Apr 29, 2025, 12:07 AM

#

I wonder if I can use vanilla Minecraft commands as a workaround for now

zealous ferry you might want to hear from someone else on this

Should I set this as a Feature Request thread or something?

#

calm nest I wonder if I can use vanilla Minecraft commands as a workaround for now

give item components a try first

#

its basically nbt

calm nest Apr 29, 2025, 12:13 AM

#

its the new NBT right?

zealous ferry Apr 29, 2025, 12:14 AM

#

yes

calm nest Apr 29, 2025, 12:14 AM

#

Not sure how to use it, since it's drawing from an ItemTag and I only have a MaterialTag from <location[].material>?

#

yeah, how do I get an EntityTag from the location?

calm nest Apr 29, 2025, 5:40 AM

#

Do people compile custom versions of Denizen? I'm thinking that it'd be relatively straightforward to modify one of the existing spawner types to match my needs

fleet canyon Apr 29, 2025, 5:51 AM

#

At that point you may as well just make a PR.

calm nest Apr 29, 2025, 6:01 AM

#

If I can get it to work, I'll do that, I haven't messed with Java in a hot minute, it may also lack the scope that people would expect

fleet canyon Apr 29, 2025, 6:05 AM

#

I'm not sure if trial spawners have proper support yet, it'd be nice to have.

#

Check #denizen-contrib

#

I've made a request to modify spawners before, because they're kind of problematic with entitys.

calm nest Apr 29, 2025, 6:10 AM

#

Okay I'd love to give it a shot
