Merge (Flowgraph Node)

Overview

• Node Name: Merge
• Category: simple
• File: extensions/flowgraph/nodes/math/vector/merge.lua

Merges up to 4 individual number components into a single table (vec3, color, or quat).

Pin Schema

Input Pins

Output Pins

How It Works

1. Each frame, the node reads the four input pins (x, y, z, w).
2. It packs them into a Lua table: {x, y, z, w}.
3. Nil inputs remain nil in the table.
4. The output type is polymorphic - it can be connected to vec3, color, or quat pins.

This is the counterpart to the Split node.

Lua Example

-- Build a position from separate coordinates:
-- x = vehicle X position
-- y = vehicle Y position  
-- z = terrain height
-- value output → vec3 position for teleport

-- Build a color:
-- x = red (0-1), y = green, z = blue, w = alpha
-- value output → color for UI element

Key Dependencies

• _flowgraph_createNode() - standard flowgraph node registration

Additional Methods

C:init()

Initializes the node, setting up pins and default properties.

C:work()

Main work function called each frame/tick when the node is active.
