Function · 1 overload

Function

Spatial queries use world coordinates.

Belongs to: epok
Header: epok.hpp
Overloads: 1

Declaration

SpatialHit raycast(const Fixed* origin,const Fixed* displacement,uint32_t mask=0xffffffffu,const ActorData* ignore=nullptr,bool triggers=false)

Spatial queries use world coordinates.

Parameter	Type	Meaning
`origin`	`const Fixed *`	Value supplied for origin. Keep referenced or pointed-to data valid for the complete call.
`displacement`	`const Fixed *`	Value supplied for displacement. Keep referenced or pointed-to data valid for the complete call.
`mask`	`uint32_t`	Value supplied for mask. Keep referenced or pointed-to data valid for the complete call.
`ignore`	`const ActorData *`	Value supplied for ignore. Keep referenced or pointed-to data valid for the complete call.
`triggers`	`bool`	Value supplied for triggers. Keep referenced or pointed-to data valid for the complete call.

Returns: SpatialHit. Check the value before continuing when it represents success, availability or a resource handle.

Example

C++ example

#include "epok.hpp"

// Assume these named values have been initialized with valid data:
// const Fixed * origin
// const Fixed * displacement
// uint32_t mask
// const ActorData * ignore
// bool triggers

auto result = epok::raycast(origin, displacement, mask, ignore, triggers);

Why use it

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

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.
