Callbacks

Typedef in ldk_system.h

LDKSystemCallbackSyncFn

Callback used to synchronize with system execution.

typedef bool(*LDKSystemCallbackSyncFn)(void *user);

Parameters

user: Opaque caller-supplied data passed to the callback.

Returns

True if the operation succeeds; false otherwise.

Typedef in ldk_system.h

LDKSystemInitializeFn

Callback called during ECS system initialization.

typedef int(*LDKSystemInitializeFn)(void *data);

Parameters

data: Source data or system-owned context for this operation.

Returns

The resulting integer value.

Typedef in ldk_system.h

LDKSystemTerminateFn

Callback called during ECS system termination.

typedef void(*LDKSystemTerminateFn)(void *data);

Parameters

data: Source data or system-owned context for this operation.

Typedef in ldk_system.h

LDKSystemUpdateFn

Callback called when an ECS system updates a group.

typedef void(*LDKSystemUpdateFn)(void *data, const LDKEntityGroup *group, float dt);

Parameters

data: Source data or system-owned context for this operation.
group: Entity group used for this system update.
dt: Elapsed time since the preceding update, in seconds.

Function in ldk_system.h

ldk_system_registry_callback_sync_set

Install an engine-side synchronization point invoked after each executed update callback. The system registry does not interpret the callback; the ECS uses it to commit deferred grouping membership changes safely between systems. Passing NULL clears the handler.

LDK_API bool ldk_system_registry_callback_sync_set(
 LDKSystemRegistry *registry,
 LDKSystemCallbackSyncFn fn,
 void *user
);

Parameters

LDKSystemRegistry *registry: Registry on which the operation is performed.
LDKSystemCallbackSyncFn fn: Callback invoked by this operation.
void *user: Opaque caller-supplied data passed to the callback.

Returns

True if the operation succeeds; false otherwise.
