Examples

local ecs = crystal.ECS:new();
ecs:add_system(crystal.PhysicsSystem);

local monster = ecs:spawn(crystal.Entity);
monster:add_component(crystal.Body);
monster:add_component(crystal.Collider, love.physics.newCircleShape(4));
monster:set_categories("characters");
monster:enable_collision_with("level", "characters");
monster:disable_collision_with("powerups", "traps");
