Lightning Bolt 2D is a geometry-based electric charge or lightning effect for your 2D Unity projects.


How to use?

After you've imported this asset, to start using it click Game Object > Effects > Lightning Bolt 2D in Unity's main menu. Or do the same by right-clicking the Hierarchy panel. This will add a new Lightning Bolt 2D object to your scene.

After this you can hit play and see it in action right away.


Arc count sets how many lines will be drawn.

Point count sets how many points each line has.

Line color, line width, glow color and glow width determine line and glow thickness and colors.

Distort sets the value that will randomly offset points of the line.

Jitter is basically the same but per-frame. It's only visible when effect is playing.

Bend amount sets how hard the line will be initially curved when it's generated.

Bend speed sets how much it will curve during playback.

There's also an FPS Limit if you only want to limit how many times per second this object is allowed to be recalculated and redrawn.

Playback options are there to let you turn this effect on and off.

If you set it to off, and if you're scene is in play mode, you can click Fire once to generate the effect and let it play out without generating it continuosly.

Regenrate lets you recalculate effect using new random valuer. It's there to be able to see differently-randomized lightnings in edit mode.

Keep in mind

Increasing number of lightnings and number of points increases the number of calculation script has to do every second. Setting them to very high values can decrease performance of your game.

How to use in code

It's easy to access all the settings in runtime. Here's an example:

//Change positions of start and end points
LightningBolt2D.startPoint=new Vector2(-8f,5f);

//How to change settings

//Stop object from generating new lightnings

//Generate lightnings once, based on your configuration

Every value you see in inspector can be modified at runtime. To see the full list of variable names refer to the source code of the asset.
