OPTIMASI SISTEM EKSPLORASI MENGGUNAKAN ROOT MOTION DAN DETEKSI INTERAKSI BERBASIS TRIGGER PADA GAME “RENEW EARTH”

The development of educational games demands not only high-quality learning
content but also visual comfort and smooth gameplay mechanics. Recent studies indicate
that Sensory Stimulation, such as animation smoothness and control responsiveness,
significantly influences players' learning interest. However, 3D character development
often faces technical challenges, such as the "foot sliding" phenomenon, which reduces
immersion, and inefficient interaction mechanisms. This study aims to optimize the
exploration and interaction systems in the educational game "ReNew Earth" using the
Unity Engine. The development method employed is the Game Development Life Cycle
(GDLC), comprising initiation, pre-production, production, testing, and release phases.
As a Game Programmer, the author implements the Root Motion technique to synchronize
animation data with object movement, effectively eliminating foot sliding. Furthermore,
the interaction system is developed using the Collider Trigger method (OnTriggerEnter),
which provides detection area tolerance, replacing the performance-heavy Raycasting
method. Design Patterns such as Singleton and Observer are also applied to ensure a
modular code structure. The results of this study are expected to produce natural
movement mechanics and a responsive interaction system, thereby enhancing the user
experience in understanding renewable energy concepts.

Pengembangan game edukasi tidak hanya menuntut kualitas materi pembelajaran,
tetapi juga kenyamanan visual dan mekanika permainan. Penelitian terbaru menunjukkan
bahwa Sensory Stimulation, seperti kelancaran animasi dan responsivitas kontrol,
berpengaruh signifikan terhadap minat belajar pemain. Namun, pengembangan karakter
3D sering kali menghadapi kendala teknis berupa fenomena foot sliding (kaki tampak
melayang) yang mengurangi imersi, serta mekanisme interaksi yang tidak efisien.
Penelitian ini bertujuan untuk mengoptimalkan sistem eksplorasi dan interaksi pada game
edukasi "ReNew Earth" menggunakan Unity Engine. Metode pengembangan yang
digunakan adalah Game Development Life Cycle (GDLC) yang terdiri dari tahap inisiasi,
pra-produksi, produksi, pengujian, hingga rilis. Sebagai Game Programmer, penulis
mengimplementasikan teknik Root Motion untuk menyinkronkan data animasi dengan
pergerakan objek guna menghilangkan foot sliding. Selain itu, sistem interaksi
dikembangkan menggunakan metode Collider Trigger (OnTriggerEnter) yang
memberikan toleransi area deteksi, menggantikan metode Raycasting yang membebani
performa. Penerapan Design Pattern berupa Singleton dan Observer juga dilakukan untuk
menjaga struktur kode yang modular. Hasil penelitian ini diharapkan dapat menciptakan
mekanika pergerakan yang natural dan sistem interaksi yang responsif, sehingga
meningkatkan pengalaman pengguna dalam memahami materi energi terbarukan.
