Cheat Engine

[mrally2]

Let’s supose I have an array of bytes A and an array of bytes B. I search for the array A in the game’s memory and got results. What do I need to do with CE to make all those adresses point to the array B?

If I swap all those adresses values ​​to the one of the array B the game crashes.

Searching for some info I found a hint but I don’t really have much clue of how to do it:

<< You need to keep changing between the playable cars and search for their hash on cheat engine. Once you found it you need to scan for its pointer. >>

I appreciate any suggestion, explanation or guide that could help me solve this problem.
