eggcar

The eggplant hot rod's particle effects in Banana 2077's neon-noir style: magenta afterburner flames, lilac tyre smoke, pale-cyan spray off the wet street, and white-gold sparks where it rams something. Every particle is a soft camera-facing card (shaders/card) that fades and shifts colour over its life; flames, spray and sparks are additive streaks stretched along their motion, and the smoke is a premultiplied puff.

Entries

Entry	Plays	How to play it
exhaust	Twin exhaust jets: a soft magenta outer flame round a white-gold core on boost, thin violet puffs on throttle. Runs until stopped.	Rooted on the car (root = car): its space is the car's, with the tips at x = +-0.35, y = -0.51, z = 2.32 (behind is +Z).
wake	Tyre smoke and spray behind the rear wheels, left in world space so it trails behind. Runs until stopped.	Rooted on a world-space parent (the player mount): the car hands it its rear tyres' contact points every frame through lx ly lz / rx ry rz.
sparks	One burst of spark streaks that arc, bounce once off the street and burn out orange. Finishes on its own after 50 frames.	offset = the contact point in world space.

Inputs

• exhaust.boost (0-1): how hard the afterburner burns; scales the flame and core streaks.
• exhaust.throttle (0-1): how hard the engine pulls; scales the violet puffs.
• wake.lx, wake.ly, wake.lz / wake.rx, wake.ry, wake.rz (m): where the left / right rear tyre meets the road, in the space the play stands in. Plain numbers, so moving them never restarts the particles.
• wake.smoke (puffs/s): tyre smoke over both wheels; raise it while drifting or wheelspinning.
• wake.spray (drops/s): spray over both wheels; rises with speed on the wet street.
• sparks.count: how many sparks the burst throws.
• sparks.force (0-3): how hard the hit was; scales spark speed and spread.
• sparks.ground (m): height of the street below the burst's origin, where sparks bounce.

Materials

flame, flame_core, spray and spark are additive; smoke is premultiplied. Each sets color_start/color_end, intensity, softness, fade, fade_in and streak on the shared card shader.
