กระบวนการสร้างเขาวงกตที่เกิดขึ้นจริงใช้อัลกอริทึมการค้นหาความลึกแรกแต่ด้วยวิธีการวนซ้ำ นี่คือวิธีการทำงาน
เราเริ่มต้นด้วยค่าอาร์เรย์ 2 มิติintแต่ละองค์ประกอบจะเป็น -1 องค์ประกอบสุ่มที่มีดัชนีเท่ากันถูกเลือกและค่าของมันจะกลายเป็น 0:
-1 -1 -1 -1 -1 -1 0 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
จากนั้นโปรแกรมจะเข้าสู่ลูปตรวจสอบเซลล์ที่มีอยู่จนกว่าจะถึงสถานะที่ไม่มีเซลล์ว่าง สิ่งนี้สามารถเกิดขึ้นได้หลายครั้งและเมื่อมันเริ่มย้อนรอย ในเวลานี้ 0s ทั้งหมดที่เจอคือ 1s นอกจากนี้ในช่วงเวลานี้คือเมื่อมันเป็นตัวกำหนดว่าควรวางทางออกที่ตำแหน่งนั้นหรือไม่ ในตอนท้ายของมันทั้งหมดอาร์เรย์อาจมีลักษณะเช่นนี้:
0 0 0 0 0 0 1 1 1
0 -1 -1 -1 -1 -1 0 -1 1
0 0 0 0 0 -1 0 -1 1
-1 -1 -1 -1 -1 -1 0 -1 1
0 0 0 0 0 0 0 -1 1
0 -1 -1 -1 -1 -1 -1 -1 1
0 -1 1 1 1 1 1 -1 1
0 -1 1 -1 1 -1 -1 -1 1
0 -1 1 -1 1 1 1 1 1
เมื่อมีจำนวนที่กำหนดไว้ล่วงหน้าเป็น 1s หรือ 0s ที่บางจุดในอาร์เรย์อาร์เรย์จะออก จากนั้นใช้อาร์เรย์เขาวงกตที่เกิดขึ้นจะถูกวาด:
มันง่ายที่จะเห็นว่า -1s ในอาร์เรย์นั้นแทนผนังและ 0s และ 1s นั้นเป็นทางเดิน รายการจะถูกกระจายแบบสุ่มตลอดเขาวงกต วงรีสีแดงคือ "ผู้เล่น" ที่คุณควบคุม
เขาวงกตถูกห่อหุ้มในบานหน้าต่างเลื่อนเพื่อความสะดวกดังนั้นหากขนาดเกินขนาดสูงสุดของเฟรมคุณสามารถเลื่อนเพื่อดูส่วนที่เหลือของเขาวงกต
ฉันจะบอกว่าปัญหาเดียวกับที่นี่คือวิธีการตรวจสอบเกมสิ้นสุด ฉันคิดหลายวิธีที่จะทำ แต่ฉันลงเอยด้วยการใช้รหัสยากทั้งหมด ฉันเปิดรับข้อเสนอแนะเกี่ยวกับวิธีการที่สามารถทำได้
