Playground

Test your NPCs directly in the browser before writing any code.

Overview

The Playground is a testing environment in the LoreMind dashboard. Use it to:

Test NPC personalities - See how Entity Minds respond to different prompts
Experiment with context - Try different locations, times, and situations
Test long-term memory - Verify NPCs remember past conversations
Iterate quickly - Refine personalities without touching code

Accessing the Playground

Go to the Playground in the dashboard

Playground main interface

Basic Testing

Selecting an Entity Mind

Choose an Entity Mind from the dropdown
Type a message in the input field
Click Send or press Enter

Entity Mind selector dropdown

The NPC responds based on its configured personality, speaking style, and available lore.

Conversation History

The Playground maintains conversation history within a session. This lets you test multi-turn conversations:


You: What's your name?
NPC: I'm Garrick, the innkeeper here at the Rusty Anvil.

You: How long have you worked here?
NPC: (Remembers they already introduced themselves as innkeeper)
     Twenty years now. Inherited the place from my father.

Click Clear Conversation to start fresh.

Adding Context

Context helps NPCs understand the situation. Click Show Context to expand the context panel.

Game Context panel

Location

Tell the NPC where the conversation is happening:

Field	Example	Effect
Location	”Town Square”	NPC knows their current location
Location Details	”Crowded market day”	Adds atmosphere

Environment

Set the time and weather:

Field	Values	Example Response
Time of Day	morning, afternoon, evening, night	”Good evening, traveler!”
Weather	clear, rainy, stormy	”Nasty weather out there, isn’t it?”
Atmosphere	peaceful, tense, festive	Affects NPC mood

Player Information

What does the NPC observe about the player?

Field	Example	Effect
Player Appearance	”Battle-worn, carrying broken sword”	NPC comments on what they see
Player Reputation	”Trusted ally”	Affects how friendly the NPC is

Recent Events

Add world events the NPC would know about:


- Dragon spotted near the village
- Merchant caravan attacked on the road
- King's birthday celebration this week

The NPC references these naturally in conversation.

Custom Context

For game-specific context, use the custom fields:


Key: active_quest
Value: Find the missing merchant

Key: faction_standing
Value: Allied with Silver Hawks

Testing Long-Term Memory

Memory lets NPCs remember players across conversations. To test:

Enable Memory

In the Playground, toggle Enable Memory
Enter a Test Player ID (e.g., “test_player_001”)

Test Player selector for memory testing

First Conversation

Tell the NPC something memorable:


You: My name is Alex. I'm searching for my lost sister.
NPC: A missing sister? That's terrible, Alex. What does she look like?

Test Recall

Click Clear Conversation (this clears session history, not memory).

Then start a new conversation:


You: Do you remember me?
NPC: Of course, Alex! Any luck finding your sister?

The NPC retrieved stored memories about Alex and the search.

Viewing Stored Memories

Click View Memories to see what the NPC has stored about this player:

Memory Inspector showing stored memories


Stored memories for test_player_001:
- Player's name is Alex
- Player is searching for their lost sister
- Player asked about strangers in town

Iterating on Entity Minds

The Playground is perfect for refining NPC personalities.

Testing Personality Changes

Talk to your NPC, note issues
Open Entity Minds in another tab
Adjust personality, hints, or restrictions
Return to Playground and test again

Example iteration:


Problem: NPC is too formal
Personality before: "Professional innkeeper who runs a clean establishment."
Personality after: "Friendly tavern keeper who loves gossip and treats regulars like family."

Testing Knowledge Filtering

If an NPC doesn’t know something they should:

Check their Knowledge Tags in Entity Minds
Verify lore documents have matching tags
Test again in Playground

If an NPC knows too much:

Remove broad tags, add specific ones
Test with questions about restricted topics

Testing Response Settings

Setting	Test By
Verbosity	Ask open-ended questions. Terse gives 1-2 sentences, Verbose gives paragraphs.
Temperature	Ask the same question multiple times. High temperature = more variation.

Tips for Effective Testing

Test Edge Cases

What if the player is rude?
What if they ask about something the NPC shouldn’t know?
What if they try to break character?

Test Consistency

Ask similar questions in different ways:


"What's your job?"
"What do you do here?"
"Are you the innkeeper?"

The NPC should respond consistently.

Test Context Awareness

Change context and ask the same question:


Context: morning, peaceful
"How's business?"
→ "Quiet morning so far. Gets busier around lunch."

Context: evening, festive
"How's business?"
→ "Packed house tonight! Festival brings everyone out."

Save Good Prompts

When you find questions that reveal personality well, save them for future testing:

“What’s the most interesting thing that happened today?”
“What do you think about [major NPC]?”
“Can you keep a secret?”

Troubleshooting

NPC gives generic responses

Cause: Too few lore documents or wrong tags
Fix: Add relevant lore, check tag assignments

NPC doesn’t remember

Cause: Memory not enabled or different player IDs
Fix: Toggle memory on, use consistent player ID

Responses are too long/short

Cause: Verbosity setting mismatch
Fix: Adjust in Entity Mind settings

NPC knows things it shouldn’t

Cause: Knowledge tags too broad
Fix: Use more specific tags, add restrictions
