Durian AoE Damage and Visual Falloff

[candour]

The Durian stand now features a more realistic AoE effect. Damage at the center of the impact is 100% and scales down linearly to 25% at the edge of the explosion radius. Visually, the expanding circle for the Durian explosion now uses a radial gradient that mirrors this decay and its size accurately reflects the stall's upgraded AoE radius.

Summary by CodeRabbit

• New Features

  • Durian weapon now applies progressive AoE damage falloff based on distance from the impact center, encouraging strategic positioning.

• Visual Improvements

  • Durian AoE effects render as expanding, fading radial-gradient ovals for clearer, more expressive area-of-effect feedback.

📝 Walkthrough

Walkthrough

This PR adds AoE metadata to VisualEffect, records per-hit distances during projectile impacts, applies a Durian-specific distance-based AoE damage falloff, and renders Durian EXPANDING_CIRCLE effects with a radial-gradient oval.

Changes

Durian AoE Damage and Rendering

Layer / File(s)	Summary
VisualEffect model with AoE metadata app/src/main/java/com/messark/hawker/model/GameModels.kt	VisualEffect data class extended with radius: Float = 0f and sourceStallType: StallType? = null.
MainViewModel hit tracking and Durian AoE damage falloff app/src/main/java/com/messark/hawker/MainViewModel.kt	Hit collection changed from projectiles-only to (Projectile, distanceFromImpact) pairs; direct hits record 0f, AoE hits record computed distToImpact. Damage calculation destructures (proj, dist) and applies Durian-specific falloff using dist / aoeRadius.
GameBoard Durian EXPANDING_CIRCLE radial gradient rendering app/src/main/java/com/messark/hawker/ui/components/GameBoard.kt	Adds conditional rendering for EXPANDING_CIRCLE effects from DURIAN stalls, drawing an isometrically-squashed radial-gradient oval sized from radius and faded using existing progress-derived alpha; other effects retain the original drawCircle path.

Lines 334-352 scale only the draw bounds, not the gradient space. That means the left/right edge reaches the intended 25% falloff, but the top/bottom edge does not, so the visual no longer mirrors the damage curve or the actual isometric radius. Use the board’s Y scale in the radius calculation and scale the shader/canvas itself, not just the oval bounds.

Good catch! I've updated the rendering logic to scale the canvas vertically based on the isometric Y factor before drawing the circle. This ensures the RadialGradient itself is squashed into the correct oval shape, matching both the visual bounds and the damage falloff curve perfectly.
