AnimEngineDemo

AnimEngineDemo is built on top of MiaoAnimEngine

Features

The demo (src/main.cpp) contrasts the two animation models AnimEngine provides, using raylib only for visualization:

• Tween vs Spring, side by side — two balls chase the same target on the X axis. Press SPACE to flip the target and watch how each model reacts.
  • RED (Tween) — fixed-duration easing (EaseInOut). Re-targeting mid-flight has to restart the animation, producing a visible snap.
  • BLUE (Spring) — physics-based, interruptible. Re-targeting keeps the current velocity and smoothly redirects, with no restart.
• 3D perspective camera, grid, and an on-screen HUD showing each ball's position and the spring's live velocity.

Building

Requirements

• CMake 3.16 or higher
• C++17 compiler
• Dependencies are included as git submodules under external/

Windows (MSVC)

mkdir build
cd build
cmake ..
cmake --build . --config Release

The executable will be generated at build\Release\demo.exe

Linux / macOS (GCC/Clang)

mkdir build
cd build
cmake ..
make -j$(nproc)  # Linux
# or
cmake --build .  # Generic

The executable will be generated at build/demo

IDE Build

If using CLion, Visual Studio, or other CMake-compatible IDEs:

1. Open the project root directory
2. The IDE will automatically detect CMakeLists.txt
3. Select build configuration (Debug/Release)
4. Click the build button

Notes

• The project automatically compiles external/raylib and external/AnimEngine dependencies
• raylib examples and games are disabled (BUILD_EXAMPLES OFF) to speed up compilation
• If git submodules are not initialized, run:

  git submodule update --init --recursive
