# Observe, Override, NewProxy

## Introduction

Cyber Engine Tweaks allow mods to listen or overwrite game's script functions/methods. There are three kinds of functions:

* [Observe](https://wiki.redmodding.org/cyber-engine-tweaks/cet-functions/observers/observe) allows to listen for function/method execution
* [Override](https://wiki.redmodding.org/cyber-engine-tweaks/cet-functions/observers/override) allows to overwrite a function/method
* [NewProxy](https://wiki.redmodding.org/cyber-engine-tweaks/cet-functions/observers/newproxy) allows to trigger a function/method callback using game's script system
