Wire Builder v1.0.2 (Latest version)
An editor tool to create suspended electricity or telephone wires in a matter of seconds. Built around an intuitive click & drag scene-view editor.
Connectors can be added to GameObjects. In turn, wires can be connected between them. Multiple connectors can form a group, allowing multiple wires to be connected (eg. utility poles).
Features:
• Intuitive click & drag scene-view editor.
• Preset-based wire type settings
• Per-wire adjustable sagging
• Adjustable wire resolution per meter
• LineRenderer or MeshRenderer wire generation
• Animated wire shader (Standard/URP)
• Compatible with 2D scene view
• Vegetation Studio tree and object removal underneath wires
Notes:
• Wires have a centered pivot so will work with World Streamer or other grid systems
• Tag and Layer can be set for generated wires
• Includes Amplify Shader Editor and URP Shader Graph functions for the shader animation effect.
Limitations:
• Wires have no collision or physics interaction
• No editing cannot be done at runtime, this is an editor-only tool
