Electric shading

Arcs take the sprite's own colour halfway to white, so blue, green and red effects keep their hue.

Arcs

• ElectricArcs = 1.5Arc brightness. 0 turns the arcs off, leaving jitter and flicker. Past 4 the arcs wash the sprite white.
• ElectricArcSharpness = 10Arc thickness. Low values give broad glowing bands, high values thin threads. Past 30 threads break into dots.
• ElectricNoiseSize = 40World units across one tile of arc noise. Smaller gives more, closer arcs. It is measured in the world, not per sprite, so a big effect carries more arcs than a small spark.

Jitter and flicker

• ElectricJitter = 0.03How far the texture jumps each crackle, in texture widths. It bends the flare's rays and edges.
• ElectricFlicker = 0.6How far brightness swings, as a fraction. It varies across the sprite and from crackle to crackle. Past 2 the dim patches go black.

Crackle rate

Each crackle moves the noise to a fresh spot, so arcs, jitter and flicker all change at once.

• ElectricRate = 15Crackles per second. 0 freezes the arcs in place. Above the frame rate every frame crackles, so higher values look the same.

Distance

The pitched camera sees the top of the screen from much further away than the bottom, and zooming out moves everything further still. Past the default camera's distance, CameraHeight over the sine of CameraPitch, arcs widen with distance so they stay at least a pixel or two wide. Without that they would thin to broken, shimmering dots.

There is no key for this. It follows CameraHeight and CameraPitch.
