My Roles

Game Research and Development Engineer Intern

Tools

Python, C++, Messiah

Duration

Junior Year, 8 weeks

Introduction

In summer 2020, I worked as Game Research and Development Engineer Intern with Netease game , developing an anti-cheating system for Game Disorder

Roles and Skills

How did I accomplish each task?

Selected Tasks

Task 1

To detect emulator players before loading the game

Solution

Tell by disparities. Use structure, software, hardware differences between emulators and Android phones to distinguish them.

Judge by vote.If users do not pass through one test, they will get one vote. If the suspected score of the user is high enough in the end, they will be considered to be emulator cheaters.

Result

We have tested this method on six popular emulators and two smart phones The result was our algorithm reach a 100% accuracy rate.

Task 2

To detect speed cheaters during the game

Solutions

Approximate Calculations: I introduced the approximate calculations in calculus, which can detect speed in any moving trails.

Judge through Other Clients: when a player is likely to be a cheater, other clients which are in the same game would examine the speed of that client.

Result

According to the chart, the reliability of the algorithm is weakened by the network transmission, but in general, although missing judgment exists, these methods can reach 100% precision.
