Why use it
It provides direct, allocation-conscious access to the world2d module. No exception-based error path is implied by the signature.

Function
Squared distance in raw Q24; |position| <= 8192 keeps this inside 2^51.
Declaration
Declaration
inline int64_t distance_squared_raw_2d(const Fixed* a, const Fixed* b)Squared distance in raw Q24; |position| <= 8192 keeps this inside 2^51.
| Parameter | Type | Meaning |
|---|---|---|
a | const Fixed * | Value supplied for a. Keep referenced or pointed-to data valid for the complete call. |
b | const Fixed * | Value supplied for b. Keep referenced or pointed-to data valid for the complete call. |
Returns: int64_t. Check the value before continuing when it represents success, availability or a resource handle.
Example
C++ example
#include "world2d.hpp"
// Assume these named values have been initialized with valid data:
// const Fixed * a
// const Fixed * b
auto result = epok::distance_squared_raw_2d(a, b);Trade-offs and warnings
Pointer/reference arguments are borrowed unless the source contract says otherwise; keep them valid for the complete operation and never assume null is accepted.
Declared in runtime/world2d.hpp:353
