modifying monobehaviours:

so in this section i'll be showing you something that you can do in most unity games but you do need to know that not every unity game will have the same functionality or will have things inside the asset bundles for you to modify.

step 1: you need to extract the ipa by converting the .ipa to a .zip and then you can extract it and it will give you the payload folder.

this is where the unity asset bundles are located at

\Payload\SubwaySurf.app\Data\Raw\aa\iOS

step 2: you can do the ctrl A shortcut to select all the files inside of the iOS folder and you will need to drag it into AssetStudio, after you did that you will wait till all the files are loaded in AssetStudio then you can navigate to the Asset List tab where you will be finding the monobehaviour for the camera FieldOfView

step 3: you will need to search for [ camConfig_Run ], once you see 1 result you will then need to right click it and press the [ Show original file ] option. You will have a new window that pops up with the highlighted bundle which then will be needed and that's where UABEA comes in for the modifying part of this tutorial.

step 4: You will need to open up UABEA and drag the highlighted bundle into UABEA, once you've done that you can click the [ Info ] button and then click the [ camConfig_Run ] monobehaviour, then finally you can click on the [ Edit Data ] button to change the FieldOfView value to whatever you want but I do wanna let you know that changing it above 120 is considered dangerous in my opinion so lets not do that you will then proceed to save as then once again you save as then you need to name the bundle to what it's named inside of the iOS Folder, as you can see what I did down below⬇️

step 5: we are getting close to the end so now you can just send the modified file to your jailbroken device, then you can use apps manager and click on subway surf then proceed to click on [ Bundle ] which from there you can go to where the asset bundles are located at and replace the bundle file with your modified bundle file. Here is what the results should look like if you did everything correctly⬇️
