Line Renderer

The Line Renderer takes an array of two or more points in 3D space and draws a straight line between each one. A single Line Renderer Component can thus be used to draw anything from a simple straight line, to a complex spiral. The line is always continuous; if you need to draw two or more completely separate lines, you should use multiple GameObjects, each with its own Line Renderer.

The Line Renderer does not render one pixel thin lines. It renders billboard lines that have width and can be textured. It uses the same algorithm for line rendering as the Trail Renderer.

Properties

Materials	The first material from this list is used to render the lines.
Positions	Array of Vector3 points to connect.
Size	The number of segments in this line.
Parameters	List of parameters for each line:
StartWidth	Width at the first line position.
EndWidth	Width at the last line position.
Start Color	Color at the first line position.
End Color	Color at the last line position.
Use World Space	If enabled, the object's position is ignored, and the lines are rendered around world origin.

Details

To create a line renderer:

1. Choose GameObject->Create Empty
2. Choose Component->Miscellaneous->Line Renderer
3. Drag a texture or Material on the Line Renderer. It looks best if you use a particle shader in the Material.

Hints

• Line Renderers are good to use for effects when you need to lay out all the vertices in one frame.
• The lines may seem to rotate as you move the Camera. This is intentional.
• The Line Renderer should be the only Renderer on a GameObject.
