• dummy the asset you want to hook (create actor with same folder structure in your unreal project)

example

• delete all events (you hook events using functions)

example

• i recommend using ue4ss to dump cxx headers to reference when dummying functions

example

#ifndef UE4SS_SDK_BP_RestChair_HPP
#define UE4SS_SDK_BP_RestChair_HPP

class ABP_RestChair_C : public AActor

    FPointerToUberGraphFrame UberGraphFrame;                                          // 0x0290 (size: 0x8)

• dummy the function you want to hook with same arguments and return type and put an hook_ before the name

example

• to call the original duplicate your dummied function and replace hook_ with orig_

example

• code whatever you want (you can dummy other functions and use them as normal)

example

• cook/package the project

example

• unpack the original asset from the game
• if your game uses paks use umodel or fmodel to do this
• if your game uses iostore use zentools-ue4 or zentools to do this
• apply hooks using spaghetti

example

spaghetti "...\pseudoregalia\Saved\Cooked\Windows\pseudoregalia\Content\Blueprints\LevelActors\BP_RestChair.uasset" "...\UModelSaved\Game\Blueprints\LevelActors\BP_RestChair.uasset" -o "...\raw\hook_p\pseudoregalia\Content\Blueprints\LevelActors\BP_RestChair.uasset" -v 5.1
BPI_TryInteract hooked

• pack your hooked blueprint into a mod
• if your game uses paks use unrealpak or repak
• if your game uses iostore use zentools-ue4 or zentools to do this
• the function should be hooked in-game! easy as pie (hopefully)

example

interacting with the chair now kills you!
