WASM Imports
Every function the SDK calls is a WASM import provided by the Xenon host at runtime. This is the complete list of imports a standard plugin can use.
All imports use the "core" import module unless otherwise noted.

Draw Parameter Conventions
- Colors are passed as normalized floats (0.0-1.0 for R, G, B, A)
thickness = 0 means "filled" for circle and rect- Rect coordinates are min/max corners, not position/size (the SDK converts)

Plugin Exports
These are the functions your plugin exports to the host:
| Export Name |
Entry Point |
Signature |
on_get_info |
Plugin metadata |
(i32) → void |
on_load |
Initialization |
() → void |

() → void |

UI |
() → void |
on_hero_changed |

Library Imports
Library dependencies use a dynamic import module: lib_<service_name>.
For example, a dependency on "math_helpers" generates imports like:
| Module |
Import Name |
Signature |
lib_math_helpers |
lerp |
(f32, f32, f32) → f32 |
lib_math_helpers |
clamp_f |
(f32, f32, f32) → f32 |
lib_math_helpers |
remap |
(f32, f32, f32, f32, f32) → f32 |
These are defined in the import header (include/xenon/libs/math_helpers.hpp).
WASM Types Reference
| Notation |
WASM Type |
C++ Type |
i32 |
