Flecs: Flecs
Flecs is a quick and light-weight Entity Part System that permits you to construct video games and simulations with hundreds of thousands of entities (join the Discord!). Listed below are a few of the framework’s highlights:

What’s an Entity Part System?
ECS is a method of organizing code and information that permits you to construct video games which are bigger, extra advanced and are simpler to increase. One thing known as an ECS when it:
- Has entities that uniquely determine objects in a recreation
- Has elements that are datatypes that may be added to entities
- Has programs that are features that run for all entities matching a part question
For extra info, test the ECS FAQ!

The Flecs playground helps you to attempt Flecs with out writing any C/C++ code!

Present me the code!
C99 instance:
typedef struct {
float x, y;
} Place, Velocity;
void Transfer(ecs_iter_t *it) {
Place *p = ecs_field(it, Place, 1);
Velocity *v = ecs_field(it, Velocity, 2);
for (int i = 0; i < it->rely; i++) {
p[i].x += v[i].x;
p[i].y += v[i].y;
}
}
int important(int argc, char *argv[]) {
ecs_set(ecs, e, Place, {10, 20});
ecs_set(ecs, e, Velocity, {1, 2});
}
FLECS_API bool ecs_progress(ecs_world_t *world, ecs_ftime_t delta_time)
Progress a world.
#outline ECS_SYSTEM(world, id, section,…)
Declare & outline a system.
ecs_id_t ecs_entity_t
An entity identifier.
struct ecs_world_t ecs_world_t
A world is the container for all ECS information and supporting options.
ecs_entity_t ecs_new_id(ecs_world_t *world)
Create new entity id.
#outline ECS_COMPONENT(world, id)
Declare & outline a part.
ecs_world_t * ecs_init(void)
Create a brand new world.
Similar instance in C++11:
struct Place {
float x, y;
};
struct Velocity {
float x, y;
};
int important(int argc, char *argv[]) {
p.x += v.x;
p.y += v.y;
});
.set([](Place& p, Velocity& v) {
p = {10, 20};
v = {1, 2};
});
whereas (ecs.progress()) { }
}
void every(Func &&func) const
Iterate over all entities with elements in argument record of operate.
flecs::entity entity(Args &&… args) const
Create an entity.
flecs::system system(flecs::entity e) const
Upcast entity to a system.
