To do this we need the start width to be 0 and the end width to be a larger number. Let’s create a triangle with the renderer. Let’s now try do something a little more complicated. LineRenderer l = gameObject.AddComponent() Let us a construct a basic line renderer script. Creating a basic unity add line renderer by script using c#

Next create a new c# script and call it unity line renderer test. Right click in the hierarchy and create a empty game object like below. So that we can just get to the part of just drawing a basic line renderer.Ĭreate a empty game object. We want to start by just setting up some basic game objects.

Create a new 2d project called unity 2d line renderer. Creating our unity 2d line renderer project Let’s get started on this unity 2d line renderer tutorial, so to start I’m going to create a basic unity project which we can experiment with. We will also look at drawing a line renderer between two game objects.ĭotted lines is also something people are quite interested in and I will look at how we can draw a unity 2d line renderer which can give us a dotted line. Drawing a unity line renderer between a mouse / screen tap, dragging it and drawing it on your scene. In this tutorial I will be going over a few principles. The unity line renderer component can also be used in building basic drawing apps using the unity engine.Īll these applications make line renderers a really important thing to learn in unity. Line renderer can also help in targetting systems where you want to draw a raycast of where a bullet might shoot to in a first person game. Where a path is drawn by dragging on a mobile screen. Line renderers are useful for drawing paths in your games.įor example a application of line renderers are in the famous game Angry Birds. This will be rendered on run time using a line renderer component in unity. You can draw color lines in 2d to help you with raycasts or just draw laser beams between two points or objects. As well as some coordinate points in unity so that you can create any sort of curves. The unity line renderer, helps you render lines, circles, and other shapes using curves.
