Single Marker (Flowgraph Node)

Overview

• Node Name: Single Marker
• Category: (default, no explicit category)
• File: extensions/flowgraph/nodes/scene/singleMarker.lua

Displays a single race-style marker at a given position. Must be manually reset when no longer needed. Supports multiple marker types and distance-based fading.

Available Marker Types

overhead, ringMarker, sideColumnMarker, sideMarker, cylinderMarker, attention, sideHologramMarker, singleHologramMarker

Behavior

• work() - Each frame:
  • On reset impulse, hides and destroys the marker.
  • On flow, creates the marker if needed using scenario/race_marker.createRaceMarker().
  • Updates position/radius when inputs change (optimized to skip unchanged frames).
  • Updates color and calls marker:update() each frame.
• fillFields() - Caches position/radius/color and applies z-offset. Returns whether values changed.
• onDrawOnMinimap() - Draws a simple circle on the minimap when the marker exists.

How It Works

1. On first flow, creates a race marker via scenario/race_marker.createRaceMarker(true, markerType).
2. Configures the marker as a checkpoint with position, radius, and optional fade distances.
3. Each frame, updates the marker's color and calls its update() method for animation.
4. The marker persists until reset is triggered or execution stops.

Key Dependencies

• require("scenario/race_marker").createRaceMarker() - marker factory
• marker:setToCheckpoint() - configures position and radius
• ui_apps_minimap_utils.simpleCircleWithEdgePointer() - minimap integration

Additional Methods

C:_afterTrigger()

Called after the node's trigger logic executes.

C:_executionStarted()

Called when graph execution starts. Used for initialization/reset.

C:_executionStopped()

Called when graph execution stops. Used for cleanup.

C:blend()

Node method.

C:hideMarker()

Node method.

C:init(mgr, ...)

Initializes the node, setting up pins and default properties.

Parameters:

• mgr
• ...

C:onClientEndMission()

Cleanup callback when the mission/level ends.

C:postInit()

Called after initialization is complete for additional setup.
