Storm & Wind 3D - 54 Lightning & Wind VFX

54 3D lightning and wind effects for Godot 4, one line of code each. Lightning strikes, arcs that chain from target to target, ball lightning, novas and storm clouds; gusts, dust devils, tornadoes and bursts of air, leaves, snow, sand, petals or ash. Shaders and meshes all made in code: no textures to import, no particle setup.

Try it first: click Run asset pack above and cast every kind in every style on a stormy moor, in your browser.

StormFX.add(self, "storm_strike")
var chain := StormFX.add(hand, "arcane_arc")
chain.aim([enemy.global_position, next_enemy.global_position])
StormFX.add(self, "sand_tornado", {radius = 2.0, height = 6.0})
StormFX.add(self, "leaves_burst", {one_shot = true})

What's inside

5 lightning kinds in 6 styles (storm, arcane, fire, toxic, holy, void): a strike from the sky that branches, flashes, throws sparks and scorches the ground; an arc between points, as many as you give it; ball lightning; a nova crackling out along the ground; a storm cloud flickering inside, striking and raining. Each comes with its light, flashing with every stroke. Void's takes light away.

4 wind kinds in 6 styles (air, leaves, snow, sand, petals, ash): a gust of streaks and what they carry blowing past, a dust devil, a tornado and a burst thrown out from a point, for a landing or a shockwave. Leaves tumble, snow drifts, sand streaks, ash rises with embers.

• Strikes on your cue: set an interval, or 0 and call strike() from your spell. The struck(at) signal tells you where it landed, for the damage.
• Loop them, or one_shot for one strike or burst that cleans up after itself.
• Any colour, radius, height, speed and intensity; light and particles switch off.
• Three ways to draw them: smooth, dithered (the PS1's ordered dither, for PSX-style games) or cut out. Per effect, or StormFX.default_transparency once for the whole game.
• What the wind carries moves on the GPU: hundreds of leaves cost one draw call.
• They bloom under an Environment with glow.
• Drop a StormFX node in a scene and it plays in the editor as you set it up.
• Demo: a moor under a storm sky with two standing stones: pick the kind and the style, click the ground to cast. Right here in the browser.
