On Bigmap Poi (Flowgraph Node)

Overview

• Node Name: On Bigmap Poi
• Category: repeat_instant
• File: extensions/flowgraph/nodes/ui/onBigmapPoiSelected.lua

Detects when a POI (Point of Interest) is selected or navigated to on the bigmap. Provides impulse outputs for selection/deselection and navigation events.

Pin Schema

Output Pins

Internals

How It Works

1. work() - Called every frame:
   • Resets all impulse outputs to false.
   • Applies any pending flags from self.flags to the output pins.
   • Outputs the current poiId and navPos (as table via toTable()).
   • Clears the flags table.
2. onPoiSelectedFromBigmap(poiId) - Hook callback:
   • If poiId is truthy, sets selected flag; otherwise sets deselected flag.
   • Stores the POI ID.
3. onSetBigmapNavFocus(pos) - Hook callback:
   • If pos is truthy, sets navigated flag; otherwise sets denavigated flag.
   • Stores the position (defaults to vec3() if nil).

The node uses a flags-based pattern: hooks set flags, and the next work() call converts them to output pin values, ensuring impulse outputs fire for exactly one frame.

Lua Code Example

-- These are the hooks the node listens to:
-- Called when user selects a POI on the bigmap:
extensions.hook("onPoiSelectedFromBigmap", "poi_gasStation_01")

-- Called when user sets navigation target:
extensions.hook("onSetBigmapNavFocus", vec3(100, 200, 50))

-- Called when navigation is cleared:
extensions.hook("onSetBigmapNavFocus", nil)

Key Dependencies

• onPoiSelectedFromBigmap hook - Fired by the bigmap UI on POI selection
• onSetBigmapNavFocus hook - Fired by the bigmap UI on navigation target change
