Energy Beam

[cosmic mesa]

You can use the parameters in this wavy line to create energy beams, waves, or threads. By using multiple lines and playing with colors and alpha, you can compose some cool effects.

creating a new beam is a simple as

 const beam = new EnergyBeam(this, {
      start: { x: 100, y: 300 },
      end: { x: 600, y: 300 },
      segments: 12,
      amplitude: 20,
      frequency: 1,
      thickness: 20,
      color: 0xFFD700,
      speed: 0.1,
    })

and then calling

beam.updateBeam()

on your update function

Interesting. I suppose it wouldn't take much to adapt that to use particles either.

yeah, it should be possible to use the path as a zone for emission. What I've done is having some particles follow the path's points https://x.com/manabattle_en/status/1898563452563562768

Designing arcane missiles with a randomized path. It's like if magic had its own will... #gamedev #indiedev @phaser_
