EngineConfig struct

#include <Runtime/Core/Public/EngineConfig.h>

Public static variables

static int Unset constexpr

Sentinel: field has not been assigned by any config file.

Public static functions

static auto LoadProjectConfig(const char* projectDir) -> EngineConfig

Load the cascading game config for projectDir.

static auto LoadEditorConfig(const char* projectDir, const EngineConfig& gameConfig) -> EngineConfig

Load the editor config overlay on top of gameConfig.

static auto LoadFromFile(const char* path) -> EngineConfig

Load a single INI file into a config struct.

Public functions

void FillFrom(const EngineConfig& other)

Copy all Unset int fields and empty strings from other into this config.

void ApplyDefaults()

Replace all remaining Unset / empty fields with compiled-in defaults.

auto GetTargetFrameTime() const -> double

Main-loop target frame time in seconds.

auto GetFixedStepTime() const -> double

Fixed simulation step duration in seconds.

auto GetNetworkStepTime() const -> double

Network update interval in seconds (time between state-correction sends).

auto GetInputNetHz() const -> int

Resolved InputNetHz, falling back to 128 if Unset.

auto GetInputNetStepTime() const -> double

Client input packet interval in seconds.

auto GetSlabUploadInlineThreshold() const -> int

Dirty entity count below which slab upload runs inline on the render thread (no job dispatch).

auto GetSlabUploadSingleJobThreshold() const -> int

Dirty entity count below which a single bundled job uploads all fields.

Public variables

bool Headless

No window, renderer, or GPU. Implied by TNX_NET_MODEL=Server.

bool EnableThreadPinning

Assign threads to specific cores for reduced jitter. Disable in PIE.

int MaxFrames

Exit after this many Sentinel frames. 0 = run indefinitely (CI: set to ~60).

int TargetFPS

Main-loop frame rate cap. Cannot be lower than FixedUpdateHz if set.

int FixedUpdateHz

Fixed-timestep logic rate (e.g., 128 or 512 Hz).

int PhysicsUpdateInterval

Fixed steps per Jolt step. 8 = 64 Hz physics at 512 Hz sim.

int NetworkUpdateHz

State-correction send rate ("tick rate"). Lower = less bandwidth.

int ClockSyncProbes

RTT probe count during Synchronizing before computing InputLead. Default: 8, range: 1–255.

int InputPollHz

Sentinel input-poll rate; higher = lower input latency.

int InputNetHz

Rate at which the client sends InputFrame packets to the Authority.

int InputDelayFrames

Artificial input delay in sim frames for lockstep/deterministic play.

int MaxClientInputLead

Max sim frames the Authority may predict ahead of a client's last received input.

int MAX_RENDERABLE_ENTITIES

Arena 1 capacity (Render + Dual partitions). Must be ≤ MAX_CACHED_ENTITIES.

int MAX_CACHED_ENTITIES

Max dynamic entities across all arenas combined.

int MAX_JOLT_BODIES

Sizes the Jolt body interface, temp allocator, and mapping arrays.

int TemporalFrameCount

Temporal ring depth. Min 8, power-of-2. At 512 Hz: 128 frames ≈ 0.25 s of history.

int JobCacheSize

Pre-allocated job queue capacity. Exceeding this value will assert.

int SlabUploadInlineThreshold

Dirty entity count below which GPU slab upload runs inline on the render thread.

int SlabUploadSingleJobThreshold

Dirty entity count below which a single bundled job uploads all fields sequentially.

char ProjectDir

Project root directory (set from TNX_PROJECT_DIR or Initialize() argument).

char DefaultScene

Scene to load on startup (relative to ProjectDir/content/).

char DefaultState

Flow state name to load on startup (e.g., "MainMenu").

uint16_t NetPort

GNS connection port (CLI: –port).

char NetAddress

Remote address for client connections (CLI: –client <ip>).

int EngineLogLevel

Min log level for the engine channel. 0=Trace … 4=Error.

int GameLogLevel

Min log level for the game channel. 0=Trace … 4=Error.

bool NoNagle

Disable GNS Nagle coalescing for all unreliable sends.

int SendRateMin

GNS per-connection send rate floor (bytes/sec). Unset = GNS default (256 KB/s).

int SendRateMax

GNS per-connection send rate cap (bytes/sec).

int AudioUpdateHz

Sentinel audio update rate (fade processing, stream refill). Default: 250 Hz.

int MaxAudioVoices

Maximum simultaneous voices; exceeded voices are stolen by priority.
