Titik Pemeriksaan

Pelajaran 16 dari 18 dalam kursus Game Roblox: Menara Tanpa Akhir di Coddy.

Jatuh hingga mati di tahap 5 dan harus mulai lagi dari bawah terasa berat. Dengan titik pemeriksaan, pemain yang mati memulai lagi dari tahap terakhir yang mereka capai, yang sudah diketahui oleh Stage.

Setiap karakter baru memicu CharacterAdded milik pemain. Roblox menempatkannya di titik spawn terlebih dahulu, jadi tunggu sebentar, lalu pindahkan:

player.CharacterAdded:Connect(function(character)
	task.wait()
	local checkpoint = towerStages[stage.Value]
	if checkpoint then
		character:PivotTo(checkpoint.Start.CFrame + Vector3.new(0, 4, 0))
	end
end)

Sebelum pemain mencapai tahap mana pun, towerStages[0] bernilai nil, jadi mereka spawn di lobi seperti biasa. Para pemenang kembali ke lobi dan sebaiknya tetap di sana.

Lava mengubah satu hal. Tahap yang telah tertutup lava bukan titik pemeriksaan: pemain yang dikembalikan ke sana akan langsung mati lagi, berulang kali, sampai lava melewati tahap berikutnya. Bandingkan Start tahap itu dengan bagian atas lava, lalu biarkan pemain yang titik pemeriksaannya berada di bawah lava tetap di lobi sampai babak berikutnya:

local covered = checkpoint and lava and checkpoint.Start.Position.Y < lava.Position.Y + lava.Size.Y / 2

Tantangan

Sulit

Di PlayerAdded, setelah membuat leaderstats, hubungkan CharacterAdded milik pemain. Tunggu sebentar dengan task.wait(), lalu, jika towerStages[stage.Value] ada, lava belum menutupi Start-nya, dan pemain belum menyelesaikan ronde ini, pindahkan karakter ke titik 4 stud di atas Start tahap tersebut.

Tekan Play, naiki satu tahap, lalu lompat turun. Setelah itu, tetaplah di sana sampai lava datang. Kemudian tekan Check.
