v2026.09.24

Apply a Classic Easter seasonal overlay: pastel Theme/StyleBox injection, confetti/shimmer VFX, elastic juice, mesh surface_override painting, cursor/audio swaps, and a date-window activation gate with player opt-out. Use when shipping holiday skins, April events, or egg-hunt juice without mutating shared .mesh/.tres assets. Keywords: pastel, seasonal Theme, StyleBox, confetti, Easter egg, surface_override, TRANS_ELASTIC, Disable Seasonal Themes, activation gate.

Overview

Seasonal "Easter-fy" toolkit: bright pastels, bouncy juice, egg/bunny iconography — gated by calendar + settings.

MANDATORY first read: easter_seasonal_activation_gate.gd — date window, Disable Seasonal Themes opt-out (user://settings.cfg), and Dev Override. Call refresh_activation() when settings change; never poll the calendar in _process.

Prerequisite: Do NOT Load godot-ui-theming until a base Theme resource exists — seasonal overlays inject StyleBox overrides; they do not replace foundational Theme authoring.

Seasonal Bootstrap (ordered)

  1. Gate — Attach easter_seasonal_activation_gate.gd; call refresh_activation() on _ready and when settings change.
  2. Theme — If gate active: MANDATORY easter_runtime_ui_themer.gd using tokens from easter_pastel_color_palette.gd.
  3. Audio — MANDATORY easter_seasonal_audio_swapper.gd to map standard UI SFX → seasonal streams.
  4. Juice — Layer confetti/shimmer/cursor/wobble scripts only after steps 1–3 pass (gate off = skip 2–4 entirely).

Core Components (Expert Easter Tools)

easter_seasonal_activation_gate.gd

MANDATORY — Date-aware manager with opt-out + Dev Override.

easter_pastel_color_palette.gd

Single source of truth for pastel Color tokens — do not hardcode hex lists in SKILL bodies or random scripts.

easter_runtime_ui_themer.gd

Runtime theme injector for applying mass pastel styles across the UI tree.

easter_squash_stretch_juice.gd

Expert 'Squash and Stretch' logic for organic egg-like interactions using Tweens.

easter_shimmer_vfx_emitter.gd

Professional 'Hidden Item' shimmer effect with additive blending and scale curves.

easter_egg_collection_tracker.gd

Expert registry for tracking hidden items with signal-based progression signals.

easter_mesh_painter_override.gd

Seasonal 3D material swapper using surface overrides to preserve base assets.

easter_wobble_physics_body.gd

Instability-driven physics body for 'Egg-like' wobbly movement.

easter_camera_pop_juice.gd

Immersive FOV 'kick' logic to emphasize collection or pop events.

easter_confetti_canon_vfx.gd

Celebratory confetti explosion with multi-colored pastel flakes.

easter_custom_cursor_manager.gd

Expert logic for swapping system mouse cursors with themed Easter icons.

easter_seasonal_audio_swapper.gd

Dynamic audio resource loader that replaces standard UI sounds with seasonal variants.

easter_palette_override.gd / seasonal_material_swapper.gd

Alternate painters — see Decision Tree — Alternate Painters above; pick one path per target.

Visual Guidelines

  • Colors: Import tokens from easter_pastel_color_palette.gd (PINK, BLUE, YELLOW, MINT, PURPLE) — never paste ad-hoc hex laundry lists into features.
  • Shapes: Rounded corners (corner_radius > 8–12). Avoid sharp edges / high-contrast blacks.
  • VFX: Confetti, sparkles, ribbons via confetti/shimmer scripts.

NEVER Do (Expert Easter Rules)

Aesthetics & Juice

  • NEVER use sharp edges or high-contrast blacks — Easter aesthetics favor rounded corners (corner_radius > 12) and soft pastel tones.
  • NEVER use standard linear scaling for pops — Linear scaling feels 'robotic.' Always use TRANS_ELASTIC or TRANS_QUART for organic eggs.
  • NEVER use billboarding for Easter particles — In close-up UI or VR, billboard sparkles look flat. Use mesh-based particles or axial rotation.

Logic & Performance

  • NEVER modify the original .mesh or .tres resource — Swapping materials on a shared Resource changes it for EVERY instance in the game. Always use surface_override or duplicate().
  • NEVER run date-checks in _process — Checking the system calendar every frame is wasteful. Run Time.get_date_dict_from_system() once on _ready or event trigger via the activation gate.
  • NEVER ignore the 'No-Seasonal' toggle — Some players hate seasonal overrides. Always provide a 'Disable Seasonal Themes' option in settings (wired through the gate's ConfigFile keys).

Elite Theming Hooks

  • Dynamic Z-Ordering: Use RenderingServer.canvas_item_set_draw_index() to dynamically move collected egg particles to the front of the UI stack without reparenting nodes.
  • Physics Interpolation: When using TRANS_ELASTIC tweens on physics-driven eggs, invoke RenderingServer.canvas_item_reset_physics_interpolation() to prevent visual "jitter" on the first frame of the pop animation.
  • StyleBox Overrides: Use Control.add_theme_stylebox_override("panel", my_stylebox) instead of modifying the global Theme to isolate seasonal changes to specific UI modules.

Expert Easter Implementation

1. Custom-Mouse-Cursor (Juice)

MANDATORY: easter_custom_cursor_manager.gd — always set a hotspot (bunny-ear tip / base).

2. Themed-Sound-Loaders

MANDATORY: easter_seasonal_audio_swapper.gd — Resource map of original → seasonal AudioStream pairs.

3. World-Environment-Override (Spring Glow)

Tween Environment ambient/tonemap/fog during a transition — never hard-cut colors mid-frame.

func _apply_spring_env(env: Environment) -> void:
    var tween := create_tween()
    tween.tween_property(env, "ambient_light_color", EasterPastelColorPalette.YELLOW, 2.0)
    tween.tween_property(env, "tonemap_exposure", 1.2, 2.0)
    tween.tween_property(env, "fog_light_color", EasterPastelColorPalette.BLUE, 2.0)
