ParticleSystem (Tiếng Việt)

Được dùng để tạo nên những hiệu ứng hay, như lửa chẳng hạn. Hệ các hạt được lập nên và vẽ trên màn hình bằng các hàm trong love.graphics. Bạn cũng cần cập nhật chúng trong callback có tên update(dt) thì mới thấy được sự biến đổi của các hạt được phát ra.

Constructor

love.graphics.newParticleSystem

Creates a new ParticleSystem.

Hàm
