GG offers xor search /edit

No need to goto address / xor value above etc etc...

Depends on the game, the offset. A game in particular you are trying?

I'm currently trying it in a sports game to calculate the distance between a package and the dword that dictates the currency required to buy- trying to apply the offset to understand other packages? Am I going in the right direction?

All it is, dword values are treated as a xor encryption.

You goto address so you can see the xor key above, use GG's built in XOR calc too calculate what the xor value will be using the xor key.

Xor key is typically 1 or 2 dword lines away. Nintendo is the rare exception. Xor key and value usually look very very similar, especially for smaller values. Encrypted searching might not always find the xor value depending on how much the value changes.
