The best solution for drawing vector-based lines in Unity! Vectrosity has much more control and flexibility than the LineRenderer component. Draw all sorts of vectors, grids, graphs, and just plain lines, fast and easy, in 2D or 3D. Get Vectrosity now Version 5.6 now available!

How it works

---

Vectrosity lines can be drawn on a canvas, or as 3D meshes drawn directly in the scene. Once the lines are drawn, they only have to be updated when needed, which makes them very fast.

To make a simple line, just call the VectorLine.SetLine function with a color and at least two points:

VectorLine.SetLine (Color.white, Vector2(100, 50), Vector2(250, 120));

If you want more options, you can make a VectorLine object. First create some points in a Vector2 or Vector3 list, which can be any size up to around 16,000 elements (Vectrosity uses screen space for 2D coordinates and world space for 3D coordinates):

var linePoints = new List.<Vector2>([Vector2(0, 0), Vector2(Screen.width-1, Screen.height-1)]);

Then make a VectorLine object, giving it a name, the points, a texture, and the line width in pixels (there are more optional parameters, but these are the basics):

var myLine = new VectorLine ("Line", linePoints, lineTexture, 2);

Then draw the line:

myLine.Draw();

Presto, you have a 2-pixel-thick line that extends from one corner of the screen to the other. You can update the points and call VectorLine.Draw again whenever you like. You can also use the transform of another object in order to move or rotate lines without having to recompute them.

This is just the start...there are lots more options and functions available to make things easy and to accomplish various effects. Vectrosity is written in C#, but you don’t have to know C# to use it, and the complete functionality is available in any language.

More demos

Try Tank Zone — it’s a retro Battle Zone remake, with increasing numbers of tanks that’ll keep you on your toes! The complete project is included when you buy Vectrosity.

Check out the line drawing demo. Lines can be any number of pixels thick, and there’s an option to fill in corners or weld joins.

Try the scribblecube demo, which fills the screen with hundreds of rotating, glowing line segments.

There's also the trail demo. This shows a ball that leaves a dotted line trail behind as it bounces around.

Grid example

---

Click for another complete script example of a dynamic grid using Vectrosity, where a GUI slider controls the pixel size of each grid square.

See the documentation for more details about how Vectrosity is used. The package also contains a guide to creating lines in the editor, and a complete reference guide to all functions.

Customer quotes

“I bought it myself and while it is super-cheap, its much, much better than what I feel like doing. I have over 20 years of game development code experience and yet buying a vector line solution was the smartest move I've made for a long time.”

“Great product and GREAT support! It has saved hours even days of my time.”

“20 minutes in and I already have my GPS route lines working. It "Just Works", my mind is blown. It's people like you who make me want to come home after a 12 hour day, and spend 6 more playing with Unity.”
