Line Renderer component

Switch to Scripting

The Line Renderer component takes an array of ii or more than points in 3D space, and draws a direct line between each i. You tin use a Line Renderer to draw anything from a elementary direct line to a complex spiral.

The line is always continuous; if you need to draw two or more than completely divide lines, you should employ multiple GameObjects The fundamental object in Unity scenes, which tin can represent characters, props, scenery, cameras, waypoints, and more. A GameObject'south functionality is defined past the Components fastened to it. More info
Run across in Glossary , each with its own Line Renderer.

The Line Renderer does not render lines that have a width in pixels The smallest unit of measurement in a figurer image. Pixel size depends on your screen resolution. Pixel lighting is calculated at every screen pixel. More info
See in Glossary . It renders polygons that have a width in earth units. The Line Renderer uses the same algorithm for line rendering The procedure of drawing graphics to the screen (or to a return texture). By default, the master photographic camera in Unity renders its view to the screen. More info
See in Glossary as the Trail RendererA visual effect that lets you to make trails behind GameObjects in the Scene as they motion. More than info
See in Glossary .

Getting started

To create a Line Renderer:

1. In the Unity menu bar, get to GameObject > Furnishings > Line.
2. Select the Line Renderer GameObject.
3. Add points to the Line Renderer's Positions assortment, either by direct setting array values in the Inspector A Unity window that displays information nigh the currently selected GameObject, nugget or projection settings, assuasive you to inspect and edit the values. More info
   Meet in Glossary window or past using the Create Points Scene Editing Mode.
4. Utilise the Inspector window to configure the color, width, and other display settings of the line.

Instance Line Renderer configuration

Line Renderer Materials

By default, a Line Renderer uses the built-in Material, Default-Line. You can make many changes to the appearance of the line without irresolute this Cloth, such as editing the color gradient or width of the line.

For other effects, such equally applying a texture to the line, you will demand to use a different Fabric. If y'all exercise not desire to write your own Shader A program that runs on the GPU. More info
See in Glossary for the new Textile, Unity's congenital-in Standard Particle Shaders work well with Line Renderers.

See Creating and using Materials for more information.

Line Renderer Scene Editing Mode

You tin can use the Line Renderer's Inspector to change the Scene A Scene contains the environments and menus of your game. Think of each unique Scene file every bit a unique level. In each Scene, you identify your environments, obstacles, and decorations, substantially designing and building your game in pieces. More info
See in Glossary Editing Mode. Different Scene Editing Modes enable yous to utilize the Scene view An interactive view into the world y'all are creating. You use the Scene View to select and position scenery, characters, cameras, lights, and all other types of Game Object. More info
See in Glossary and the Inspector to edit the Line Renderer in different ways.

There are three Scene Editing Modes: None, Edit Points, and Create Points.

Setting the Scene Editing Style

Line Renderer Edit Points and Create Points buttons

Use the Edit Points and Create Points buttons at the superlative of the Inspector to gear up the current Scene Editing Mode.

Click the Edit Points button to set the Scene Editing Mode to Edit Points. Click information technology again to set the Scene Editing Manner to None.

Click the Create Points button to prepare the Scene Editing Mode to Create Points. Click information technology over again to set the Scene Editing Style to None.

Scene Editing Style: None

Line Renderer Simplify controls

When no Scene Editing Mode is selected, you can configure and perform a simplification operation that removes unnecessary points from the Positions array.

The following controls are visible in the Inspector:

Control	Description
Simplify Preview	Enable Simplify Preview to see a preview of the results of the simplification operation.
Tolerance	Set the amount by which the simplified line can deviate from the original line. A value of 0 results in no deviation, and therefore little or no simplification. College positive values event in more departure from the original line, and therefore more than simplification. The default value is 1.
Simplify	Click Simplify to reduce the number of elements in the Line Renderer'south Positions array. The simplification operation uses the Ramer-Douglas-Peucker algorithm to reduce the number of points, based on the Tolerance value.

Scene Editing Mode: Edit Points

Line Renderer in Edit Points Scene Editing Style

When the Scene Editing Mode is set to Edit Points, Unity represents each point in the Line Renderer's Positions assortment as a yellowish sphere in the Scene view. You lot can move the individual points using the Motion tool.

The following controls are visible in the Inspector:

Command	Description
Show Wireframe	When enabled, Unity draws a wireframe in the Scene view that visualizes the line.
Subdivide Selected	This button is enabled when you select two or more adjacent points. Pressing this button inserts a new point between the selected adjacent points.

Scene Editing Way: Create Points

Line Renderer in Create Points Scene Editing Mode

When the Scene Editing Fashion is set to Create Points, you lot tin click within the Scene view to add together new points to the end of the Line Renderer'southward Positions array.

The post-obit controls are visible in the Inspector:

Control		Clarification
Input		Gear up the input method you desire to utilise to create points.
	Mouse position	Create points based on the mouse position in the Scene view.
	Physics Raycast	Create points based on a raycast into the Scene. Unity creates the point at the position where the raycast hits.
Layer Mask A value defining which layers to include or exclude from an operation, such equally rendering, collision or your ain code. More info Meet in Glossary		The layer mask to use when performing a raycast. This holding is visible only when Input is set to Physics Raycast.
Min Vertex Altitude		When you drag the mouse to create points in the Scene view, the Line Renderer creates a new point when this distance from the last signal is exceeded.
Offset		The offset applied to created points. When Input is set to Mouse Position, Line Renderer applies the offset from the Scene camera A component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info Run into in Glossary . When Input is set up to Physics Raycast, Line Renderer applies the outset from the raycast normal.

Line Renderer Inspector reference

This section contains the following sub-sections:

• Line settings
• MaterialsAn asset that defines how a surface should exist rendered. More info
  See in Glossary
• Lighting
• Probes
• Boosted Settings

Line settings

Holding		Function
Loop		Enable this to connect the first and terminal positions of the line, and course a closed loop.
Positions		The assortment of Vector3 points to connect.
Width		Define a width value, and a curve value to control the width of your line along its length. The curve is sampled at each vertex, then its accurateness is limited by the number of vertices in your line. The overall width of the line is controlled by the width value.
Color		Define a gradient to command the color of the line forth its length. Unity samples colors from the Color gradient at each vertex. Between each vertex, Unity applies linear interpolation to colors. Adding more vertices to your line might give a closer approximation of a detailed gradient.
Corner Vertices		This property dictates how many extra vertices are used when drawing corners in a line. Increase this value to brand the line corners appear rounder.
End Cap Vertices		This property dictates how many actress vertices are used to create finish caps on the line. Increment this value to make the line caps appear rounder.
Alignment		Set the direction that the line faces.
	View	The line faces the Camera.
	TransformZ	The line faces the Z axis of its Transform component A Transform component determines the Position, Rotation, and Scale of each object in the scene. Every GameObject has a Transform. More info Encounter in Glossary .
Texture Manner		Control how the Texture is applied to the line.
	Stretch	Map the texture once forth the entire length of the line.
	Tile	Repeat the texture along the line, based on its length in world units. To set the tiling rate, apply Cloth.SetTextureScale.
	DistributePerSegment	Map the texture one time along the entire length of the line, assuming all vertices are evenly spaced.
	RepeatPerSegment	Repeat the texture along the line, repeating at a rate of once per line segment. To adjust the tiling rate, utilize Material.SetTextureScale.
Shadow Bias		Prepare the amount to move shadows away from the Calorie-free to remove shadowing artifacts cused by approximating a volume with billboarded geometry.
Generate Lighting Data		If enabled, Unity builds the line geometry with normals and tangents included. This allows it to apply Materials that use the Scene lighting.
Use World Space		If enabled, the points are considered as earth space coordinates. If disabled, they are local to the transform of the GameObject to which this component is attached.

Materials

The Materials section lists all the materials that this component uses.

Property	Clarification
Size	The number of elements in the material listing. If you decrease the number of elements, Unity deletes the elements at the end of the listing. If you increment the number of elements, Unity adds new elements to the terminate of the list. Unity populates new elements with the same cloth that the chemical element at the end of the list uses.
Element	The materials in the list. You can assign a material asset to each element. Past default, Unity orders the listing alphabetically based on the name of the materials. This list is reorderable, and Unity updates the number of the elements automatically as you lot change their society.

Lighting

The Lighting department contains properties that relate to lighting.

Belongings		Description
Cast Shadows		Specify if and how this Renderer casts shadows when a suitable Light shines on it. This property corresponds to the Renderer.shadowCastingMode API.
	On	This Renderer casts a shadow when a shadow-casting Light shines on it.
	Off	This Renderer does not cast shadows.
	Two-sided	This Renderer casts two-sided shadows. This ways that single-sided objects like a plane or a quad tin cast shadows, even if the light source is behind the mesh. For Baked Global Illumination or Enlighten Realtime Global Illumination to support two-sided shadows, the material must support Double Sided Global Illumination.
	Shadows Only	This Renderer casts shadows, but the Renderer itself isn't visible.
Receive Shadows		Specify if Unity displays shadows cast onto this Renderer. This property only has an effect if y'all enable Broiled Global Illumination or Enlighten Realtime Global Illumination for this scene. This property corresponds to the Renderer.receiveShadows API.
Contribute Global Illumination		Include this Renderer in global illumination calculations, which accept place at bake fourth dimension. This property only has an effect if y'all enable Broiled Global Illumination or Enlighten Realtime Global Illumination for this scene. Enabling this property enables the Contribute GI flag in the GameObject's Static Editor Flags. It corresponds to the StaticEditorFlags.ContributeGI API.
Receive Global Illumination		Whether Unity provides global illumination data to this Renderer from baked lightmaps, or from runtime Light Probes. This belongings is but editable if you lot enable Contribute Global Illumination. It merely has an effect if you enable Baked Global Illumination or Enlighten Realtime Global Illumination for this scene. This belongings corresponds to the MeshRenderer.receiveGI API.
	Lightmaps	Unity provides global illumination information to this Renderer from lightmaps.
	Light Probes	Unity provides global illumination data to this Renderer from Light ProbesLite probes store data about how lite passes through infinite in your scene. A collection of calorie-free probes arranged within a given infinite can improve lighting on moving objects and static LOD scenery within that space. More info Come across in Glossary in the scene.
Prioritize Illumination		Enable this property to always include this Renderer in Enlighten Realtime Global Illumination calculations. This ensures that the Renderer is afflicted past distant emissives, even those which are normally excluded from Global Illumination calculations for performance reasons. This property is visible only if Contribute GI is enabled in the GameObject's Static Editor Flags, your projection uses the Congenital-in Render Pipeline, and Enlighten Realtime Global Illumination is enabled in your scene.

Probes

The Probes department contains backdrop relating to Light Probe and Reflection ProbesA rendering component that captures a spherical view of its environs in all directions, rather like a photographic camera. The captured epitome is then stored as a Cubemap that can be used by objects with reflective materials. More info
Run across in Glossary .

Property		Description
Low-cal Probes		Prepare how this Renderer receives calorie-free from the Calorie-free Probes system. This belongings corresponds to the Renderer.lightProbeUsage API.
	Off	The Renderer doesn't use any interpolated Calorie-free Probes.
	Blend Probes	The Renderer uses one interpolated Low-cal Probe. This is the default value.
	Employ Proxy Book	The Renderer uses a 3D grid of interpolated Low-cal Probes.
	Custom Provided	The Renderer extracts Calorie-free Probe shader uniform values from the MaterialPropertyBlock.
Proxy Book Override		Prepare a reference to another GameObject that has a Light Probe Proxy Volume component. This property is just visible when Light Probes is set to Utilise Proxy Book.
Reflection Probes		Set how the Renderer receives reflections from the Reflection Probe organisation. This holding corresponds to the Renderer.probeAnchor API.
	Off	Disables Reflection Probes. Unity uses a skybox for reflection.
	Blend Probes	Enables Reflection Probes. Blending occurs only between Reflection Probes. This is useful in indoor environments where the character may transition between areas with different lighting settings.
	Alloy Probes and Skybox	Enables Reflection Probes. Blending occurs between Reflection Probes, or between Reflection Probes and the default reflection. This is useful for outdoor environments.
	Elementary	Enables Reflection Probes, just no blending occurs between Reflection Probes when at that place are 2 overlapping volumes.
Anchor Override		Set the Transform that Unity uses to determine the interpolation position when using the Light Probe or Reflection Probe systems. By default, this is the centre of the bounding box of the Renderer's geometry. This property corresponds to the Renderer.probeAnchor API.

Boosted Settings

The Additional Settings section contains additional backdrop.

Belongings		Description
Motion Vectors		Set whether to employ motion vectors to runway this Renderer'due south per-pixel, screen-space motion from i frame to the next. You can use this information to apply mail service-processing effects such as motility blur. Note: not all platforms back up movement vectors. See SystemInfo.supportsMotionVectors for more information. This holding corresponds to the Renderer.motionVectorGenerationMode API.
	Photographic camera Motion Simply	Apply only Camera movement to track motion.
	Per Object Motion	Apply a specific pass to rail motion for this Renderer.
	Force No Motion	Do not track motion.
Dynamic Occlusion		When Dynamic Occlusion is enabled, Unity'southward apoplexy cullingA feature that disables rendering of objects when they are not currently seen by the camera because they are obscured (occluded) past other objects. More info Come across in Glossary organisation culls this Renderer when it is blocked from a Camera'south view past a Static Occluder. Otherwise, the system does non choose this Renderer when it is blocked from a Photographic camera's view by a Static Occluder. Dynamic Occlusion is enabled by default. Disable it for furnishings such as drawing the outline of a character behind a wall.
Sorting Layer		The name of this Renderer's Sorting Layer.
Society in Layer		This Renderer's order within a Sorting Layer.
