Have you ever wanted to draw lines in your Unity game? Maybe you're creating a laser beam, a route, or even a spider's web. If so, the LineRenderer class is just the tool you need! The LineRenderer class in Unity enables developers to draw a series of connected segments in your scene directly from your scripts. LineRenderer is immensely versatile and can be used for almost anything that requires a dynamic line. You can customize the line's appearance using various properties like width, color, and texture. In addition, you can precisely control the line's shape by defining the points that the LineRenderer passes through. Want to create a glowing neon trail in a dark room? Or the trajectory of a projectile? The LineRenderer has got you covered. Unity's LineRenderer Documentation
Properties
The 'endColor' property modifies the color at the end of the line. Like 'startColor', this can help to create colorful gradients on your line. Unity's LineRenderer.endColor Documentation
The 'endWidth' property works similar to 'startWidth', but it controls the width at the end of the line, effectively determining the tapering of the line. Unity's LineRenderer.endWidth Documentation
The 'generateLightingData' property decides whether or not to generate lighting data for the line. Unity's LineRenderer.generateLightingData Documentation
The 'loop' property, when set to true, connects the start and end of the line, forming a continuous loop. Unity's LineRenderer.loop Documentation
The 'numCapVertices' property dictates how many vertices are used to form the end cap of the line, controlling how rounded the end of a line appears. Unity's LineRenderer.numCapVertices Documentation
The 'numCornerVertices' property influences how many vertices are created when the line bends at a corner. It comes in handy when designing smoother or sharper corners. Unity's LineRenderer.numCornerVertices Documentation
The 'positionCount' property is used to indicate how many vertices the line has, effectively defining the line's complexity. Unity's LineRenderer.positionCount Documentation
The 'shadowBias' helps in eliminating undesired lines by tweaking the rendering of shadows. Unity's LineRenderer.shadowBias Documentation
The 'startColor' property defines the color at the start of the line. You can achieve cool gradient effects by having different start and end colors. Unity's LineRenderer.startColor Documentation
The 'startWidth' property controls the width at the start of the line. Changing this value will make the beginning of the line wider or narrower. Unity's LineRenderer.startWidth Documentation
The 'textureScale' property affects how often a texture is repeated along the line. Unity's LineRenderer.textureScale Documentation
The 'useWorldSpace' property allows the line to move along with the GameObject if set to false, else the line will be drawn in the global space. Unity's LineRenderer.useWorldSpace Documentation
With 'widthCurve', you can apply a complex pattern to the variation of width along the line. It essentially provides you a powerful tool to craft the line's width to your desire. Unity's LineRenderer.widthCurve Documentation
The 'widthMultiplier' property multiplies the width of the line by a certain factor, effectively scaling the whole line's width. Unity's LineRenderer.widthMultiplier Documentation
Methods
The 'BakeMesh' method allows you to create a static Mesh from the line. This could be extremely useful for saving the state of a line, or for use in other Mesh-based systems. Unity's LineRenderer.BakeMesh Documentation

Parameters
mesh
useTransform
Returns
The 'GetPosition' method retrieves the position of a particular point along the line, helping in understanding and debugging the line's shape. Unity's LineRenderer.GetPosition Documentation
Parameters
index
The index of the position to retrieve.
Returns
Returns the current position of the specified point on the line.
The 'SetPosition' method allows you to manually set the position of any point along the line. This is important for defining the line's shape. Unity's LineRenderer.SetPosition Documentation
Parameters
index
The index of the position to be modified.
position
The new position for the specified point along the line.
Returns
Parameters
positions
Returns
The 'Simplify' method simplifies the shape of the line using the Ramer-Douglas-Peucker algorithm, reducing the number of vertices on the line. This can help to decrease rendering cost. Unity's LineRenderer.Simplify Documentation
Parameters
tolerance
The maximum allowed error when simplifying the line.
