# NPC Influence System
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
Every NPC in Break Escape tracks an **influence** variable representing the player's relationship with them. Influence changes trigger visual feedback to show the player when they've improved or damaged a relationship.
|
||
|
|
|
||
|
|
## Ink Implementation
|
||
|
|
|
||
|
|
### Variable Declaration
|
||
|
|
|
||
|
|
In your Ink story, declare an `influence` variable for each NPC:
|
||
|
|
|
||
|
|
```ink
|
||
|
|
VAR influence = 0
|
||
|
|
VAR npc_name = "Agent Smith"
|
||
|
|
```
|
||
|
|
|
||
|
|
### Triggering Influence Changes
|
||
|
|
|
||
|
|
When the player does something that changes the relationship, modify the `influence` variable and add the corresponding tag:
|
||
|
|
|
||
|
|
#### Increasing Influence
|
||
|
|
|
||
|
|
```ink
|
||
|
|
=== helpful_choice ===
|
||
|
|
You helped me out. I won't forget that.
|
||
|
|
~ influence += 1
|
||
|
|
# influence_increased
|
||
|
|
-> hub
|
||
|
|
```
|
||
|
|
|
||
|
|
This displays: **"+ Influence: Agent Smith"** (green)
|
||
|
|
|
||
|
|
#### Decreasing Influence
|
||
|
|
|
||
|
|
```ink
|
||
|
|
=== rude_choice ===
|
||
|
|
That was uncalled for. I expected better from you.
|
||
|
|
~ influence -= 1
|
||
|
|
# influence_decreased
|
||
|
|
-> hub
|
||
|
|
```
|
||
|
|
|
||
|
|
This displays: **"- Influence: Agent Smith"** (red)
|
||
|
|
|
||
|
|
## Visual Feedback
|
||
|
|
|
||
|
|
The influence system automatically shows a popup notification:
|
||
|
|
|
||
|
|
- **Position**: Top center of screen
|
||
|
|
- **Duration**: 2 seconds
|
||
|
|
- **Appearance**: Pixel-art styled with sharp borders (no border-radius)
|
||
|
|
- **Colors**:
|
||
|
|
- Green (#27ae60) for increases
|
||
|
|
- Red (#e74c3c) for decreases
|
||
|
|
|
||
|
|
## Example Usage
|
||
|
|
|
||
|
|
```ink
|
||
|
|
VAR influence = 0
|
||
|
|
VAR trust_level = "stranger"
|
||
|
|
|
||
|
|
=== hub ===
|
||
|
|
{influence >= 5: ~ trust_level = "friend"}
|
||
|
|
{influence >= 10: ~ trust_level = "trusted ally"}
|
||
|
|
{influence <= -5: ~ trust_level = "suspicious"}
|
||
|
|
|
||
|
|
Hey there, {trust_level}.
|
||
|
|
|
||
|
|
+ [Ask for help]
|
||
|
|
-> ask_help
|
||
|
|
|
||
|
|
+ [Be rude]
|
||
|
|
-> be_rude
|
||
|
|
|
||
|
|
=== ask_help ===
|
||
|
|
Sure, I can help with that.
|
||
|
|
~ influence += 1
|
||
|
|
# influence_increased
|
||
|
|
-> hub
|
||
|
|
|
||
|
|
=== be_rude ===
|
||
|
|
Wow, okay. Forget I asked.
|
||
|
|
~ influence -= 2
|
||
|
|
# influence_decreased
|
||
|
|
-> hub
|
||
|
|
```
|
||
|
|
|
||
|
|
## Technical Details
|
||
|
|
|
||
|
|
- **Tags processed**: `# influence_increased` and `# influence_decreased`
|
||
|
|
- **Implementation**: `js/minigames/helpers/chat-helpers.js`
|
||
|
|
- **Popup function**: `showInfluencePopup(npcName, direction)`
|
||
|
|
- **NPC name source**: Uses `displayName` → `name` → `npcId` fallback
|
||
|
|
|
||
|
|
## Best Practices
|
||
|
|
|
||
|
|
1. **Use meaningful increments**: ±1 for small actions, ±2-3 for significant choices
|
||
|
|
2. **Track thresholds**: Use influence levels to unlock new dialogue options
|
||
|
|
3. **Show consequences**: Let NPCs react differently based on influence
|
||
|
|
4. **Balance carefully**: Avoid making influence too easy to maximize or minimize
|
||
|
|
5. **Be consistent**: Similar actions should have similar influence impacts
