Skia Platformer Game v0.4

A feature-rich 2D platformer prototype built entirely with Skia (FMX + Skia4Delphi). What started as a 2-hour "can I do this?" challenge has evolved into a fully playable endless scroller with procedural generation, physics, audio and visual effects. A nice base to start with, its all easy to see how it works in only one file.

SkiaPlatformer Preview 🎮 Gameplay Features

This isn't just a static tech demo anymore. It's a vertical slice of a platformer engine:

Procedural Generation: Every level is randomly generated. It ensures gaps are jumpable, platforms are "mostly" reachable, and high "Sky Islands" reward exploration.
Stargate Levels: Find the portal at the end of the map to teleport to the next level.
Dynamic Worlds: The background changes based on the level (Day, Night, Sunset, Alien World). Trees and clouds adjust their colors to match the sky.
Enemies: Encounter "Ghosts" that patrol platforms. Touch them, and it's game over! But watch out—they can fall into pits just like you.
Physics & Juice: Smooth gravity, friction, and particle explosions. Crates explode with a satisfying burst when collected.
Responsive Controls: Tight movement with friction and acceleration.

🕹️ Controls

Move Left: A or Left Arrow
Move Right: D or Right Arrow
Jump: W, Space, or Up Arrow
Pause Menu: M or Escape
Reset Level: R (While paused)
Switch Avatar: C (Cat or stickman)

🛠️ Technical Details

Renderer: Pure Skia Canvas (No Game Engine, no FMX shapes).
Threading: Physics runs on a background thread for consistent FPS, synchronized with the main rendering thread.
Animations: Procedural "sine-wave" animations for the stickman (swaying, breathing, running legs).
Effects: Heavy use of TSkMaskFilter for glowing platforms, blurry clouds, and neon UI.

📦 What's Inside

SkiaPlatformer.pas: The complete game engine in a single file.
Sample project and executable included.

🚀 Getting Started

Open the project in RAD Studio (Delphi).
Ensure you have the Skia4Delphi library installed.
Run and play!

----Latest Changes
v 0.4:

• Added Audio effect system with royalty free audios from
  https://www.pavsmusic.com/free-sound-pack-kits/

v 0.3:

• Added cat avatar -> Toggle between "Organic" and "Cat" avatars by pressing 'C'.
• Cat Avatar features tail wagging, ear rendering, and directional head movement.
• Added a new "Far Mountains" background layer with parallax scrolling;
• Fixed - all scenery (trees, mountains) now anchors to the bottom of the screen,
  eliminating floating elements over pits.
• Physics & Controls: Reworked friction logic to use exponential deceleration.
  movement now stops instantly and cleanly without the "wiggle" or coasting delay.

v 0.2:

• Added Procedural Map Generation (Gaps, Floating Platforms).
• Added Enemies (Ghosts) with basic AI.
• Added Gate at end of level with world themes.
• Added Pause Menu (M/ESC) and Reset functionality.
• Expanded Controls: WASD + Arrows + Space.
• Added Parallax Backgrounds (Trees, Clouds) matching time of day.

v 0.1: Initial Alpha

• Implemented core AABB collision detection.
• Added "Alive" procedural animation for avatar.
• Integrated particle emitter system.
