| #define ecs_float_t float |
| #define ecs_ftime_t ecs_float_t |
| #define FLECS_COREDOC |
| #define FLECS_DEBUG |
| #define FLECS_ENTITY_PAGE_BITS (12) |
| #define FLECS_EVENT_DESC_MAX (8) |
Maximum number of events in ecs_observer_desc_t.
| #define FLECS_EXPR |
| #define FLECS_HI_COMPONENT_ID (256) |
This constant can be used to balance between performance and memory utilization.
The constant is used in two ways:
Increasing this value increases the size of the lookup array, which allows fast table traversal, which improves performance of ECS add/remove operations. Component ids that fall outside of this range use a regular map lookup, which is slower but more memory efficient.
| #define FLECS_HI_ID_RECORD_ID (1024) |
This constant can be used to balance between performance and memory utilization.
The constant is used to determine the size of the id record lookup array. Id values that fall outside of this range use a regular map lookup, which is slower but more memory efficient.
| #define FLECS_HTTP |
| #define FLECS_ID_DESC_MAX (32) |
Maximum number of ids to add ecs_entity_desc_t / ecs_bulk_desc_t.
| #define FLECS_LOG |
| #define FLECS_META_C |
| #define FLECS_MONITOR |
| #define FLECS_NO_DEPRECATED_WARNINGS |
| #define FLECS_OS_API_IMPL |
| #define FLECS_QUERY_SCOPE_NESTING_MAX (8) |
| #define FLECS_SPARSE_PAGE_BITS (12) |
This constant is used to determine the number of bits of an id that is used to determine the page index when used with a sparse set.
The number of bits determines the page size, which is (1 << bits). Lower values decrease memory utilization, at the cost of more allocations.
| #define FLECS_TERM_DESC_MAX (16) |
Maximum number of terms in ecs_filter_desc_t.
