Game Programming Concepts Quiz

A technique used to modify the behavior of a program by redirecting the execution flow to a different location in memory.

A section of memory in a program that is reserved for storing additional instructions.

The original instructions in a program are copied to a code cave, preserving the original functionality.

The original instruction is modified to jump to the newly created code cave.

After executing the instructions in the code cave, the execution flow needs to return to the original code.

A combination of instructions within a code cave that allows for adding new functionality to a game without removing the original functionality.

The original instruction is replaced with a jump instruction that points to the code cave.

Code caves allow us to create new functionality in a game by modifying the behavior of existing instructions.

A technique used by operating systems to allocate memory dynamically at runtime as needed.

A process of attaching a debugger to a running program to analyze its behavior and modify its code.

A code snippet that interrupts the program's execution at a specific point.

A debugger command used to disable a specific instruction, preventing it from being executed.

A representation of memory addresses in hexadecimal format (using numbers 0-9 and letters A-F).

The part of a debugger that displays the source code being executed line-by-line.

The part of a debugger that displays memory contents in both hexadecimal and ASCII representation.

A debugging tool used to examine and manipulate the state of a program during execution.

In game programming, a class is a blueprint for creating objects, defining the attributes and functions of a specific entity. Each object is an instance of that class, holding its own unique data.

The Player class represents a player in a game, containing information like their name, money, and other relevant data. It also defines actions the player can take, like increasing their money.

In video games, a list (array) holds multiple objects, like Player instances. This allows you to manage many players simultaneously and loop through them to access their individual data.

Games require loading large resources like images and sounds. This is done during setup to make them available in RAM (computer memory) for use during gameplay.

Moving data between RAM and CPU registers is crucial for game performance. The mov command copies a value from a specific memory location to a register, allowing the CPU to quickly access and manipulate data.

Games use class locations in memory to access specific data within objects, allowing for efficient manipulation of object data.

Multiplayer games allow multiple players to interact by using client-server models. Each player's game has its own client, which sends updates to the server.

Clients in multiplayer games store local player data and send updates to the server whenever there's a change, ensuring synchronized gameplay.

A method of defeating DMA by finding a location in the code where the targeted value is accessed and redirecting execution to a specific area (code cave) to store and access it.

A technique used in DMA defense where the original code's execution is manipulated to access the target value indirectly by tracing back the flow of registers and offsets.

A technique used to defeat DMA by analyzing the code responsible for modifying a target value and then reversing the flow of registers and offsets to locate the base pointer for that value.

A key component in reversing DMA, where the base pointer provides a starting point for calculating the address of a specific value within a program's memory.

The value that represents the player's current gold amount in a game.

The class that represents a player's data and actions in a game.

Direct Memory Access (DMA) is a method used to bypass the normal data transfer process in a system, potentially leading to security vulnerabilities or unintended consequences.

A specific version of the Wesnoth game targeted for analysis and security research.

A function in Windows.h used to read memory from a running process. It needs the process handle, base address, buffer to store the data, size of data, and a variable to hold the number of bytes read.

A 32-bit unsigned integer data type used to store data in the ReadProcessMemory() function.

The starting address in memory where the data is stored.

A variable that stores the number of bytes actually read by ReadProcessMemory().

A region of memory allocated to store the data read by ReadProcessMemory().

A fundamental principle in game hacking where a player's gold value is dynamic (changes between games) while the player's profile remains static (constant across games). This difference enables us to find the addresses of both the dynamic gold and the static player class.

A technique used to find the address of a player's gold value within a game. By understanding the relationship between dynamic and static values, we can use the static Player class address to deduce the dynamic gold value's address.

A reference point used to locate the dynamic gold address. It's usually a constant address, making it a reliable point of reference for finding other values.

A variable in a game that changes its value during gameplay. Examples include a player's gold, turn number, and health.

A variable in a game that retains its value throughout multiple gameplay sessions. Examples include a player's profile name, statistics, and achievements.

The process of utilizing a Player Class address to access the dynamic gold address in a game. It involves calculating the relative offset between these addresses to determine the gold's location.

The process of increasing a player's gold value during a game. In most games, this usually happens at the end of a turn.
