Reverse Theory Knowledge 3 [UI Modification]

Game common sense: In 2D games, the characters, tents and skill bars we see are displayed on the graphics card through texture technology

Actual combat: Modify the position of the skill bar image on the screen in the game

One. Modification ideas

1. The drawing technology of the game→drawing function→use the coordinates→modify it→the scheme is not feasible!

 Reason: A. There are too many places on the screen that need to use coordinates, it is difficult to determine the coordinates of the skill bar, and it needs to be excluded one by oneB. The game will definitely re-encapsulate the underlying functions such as drawing functions, even if the data is obtained, it is not easy to analyze

2.Ctrl+F9 can show/hide the icon, showing that the drawing technology is used → drawing function → use coordinate → modify it → feasible

Guess: The show/hide function is controlled by a bool variable whether to draw or not

Evidence: Demonstration with CE's data search function

When the switch is 1, the game will call the drawing function, then it will must use the coordinates.

3. Object-oriented technology
Guessing: guessing that object-oriented technology is used in the game
Demonstration: when the skill bar is displayed, use CE's find out what visited the addressForensics

If the game uses object-oriented technology, then the UI coordinate data must be in the member property of the class

Observe, modify data for testing

How do I generate a patch?

• From the data observation of CE, we know that the green one represents global variables; there are two possibilities, either the innate value or the later value
• So we can follow the entry point to track it, then lock the value, and generate the patch

Two. Use solution 2 to implement the UI correction function
