About LCPDFR

The LCPD First Response (LCPDFR) Mod, is a modification for the PC version of Grand Theft Auto IV (and Grand Theft Auto: Episodes from Liberty City). LCPDFR turns the entire concept of GTA titles upside down, and puts the player on the other side of the thin blue line - arresting crooks, not working for them.

Put simply, LCPDFR builds upon the core gameplay of GTA IV to offer a whole bunch of new features, such as the ability to arrest, detain or search anyone, as well as the ability to pull over vehicles, get into high speed chases and respond to calls.
It was created by Sam in August 2009, originally posted on GTAForums.

At the beginning of July 2009, I came up with the idea of filming some sort of COPS TV show style series set in Liberty City and recorded in GTA IV. Obviously, this turned out to be no easy task with a lack of tools available to do anything other than shoot up a bunch of bad guys. Never the less, using the default Vigilante police computer missions and the Player Selector mod, I would change model to the police one, spawn a cop bodyguard and respond to the calls. This did, however, get a little bit too repetitive, unrealistic and boring for me to make any real series of it as every video was basically just a 'drive here, kill this guy' sort of set up. After searching for a few more mods to try to help with the filming and provide more variety, I stumbled across the .Net Scripthook for GTA IV by HazardX. I took a quick look at some of the example scripts, and using my very limited, school taught knowledge of VB.net, began making some simple changes. After a few days of playing around with the Scripthook, I managed to make some very simple things of my own such as a keybind(ALT +B) to call for backup. This was something which was really crucial to the entire series as without any method of attaining backup, things were just even more repetitive and unrealistic. So, using some rather simple and buggy code, I just created a police car, put 2 cops inside it, and had it drive to my location. This was, I guess, what motivated me to keep on developing this simple filming script. Calling in backup was now done, and I could simply press a key and have a car respond, rather than having to dial 911 which was much, much better. Looking at what I had done with the backup key, I then added another keybind, ALT + P, which set my model to be the cop one, gave me a glock and spawned a police car for me.

This process of realising the potential of scripting in GTA IV continued to reiterate, with me discovering something else, and adding it in, such as the ALT + H keybind, which at first was merely a way of making the player and the closest ped synchronise the cuffing animation. After another couple of days, I had added quite a few things into the mod, including frisking, arresting, helicopter backup (which was largely taken from an open source trainer), and normal backup. I had a quick look at GTAForums again, and I saw that there was an active discussion going on, in a taxi mod thread, about how cool a police mod for the game would be. I suppose this is what inspired LCPDFR, as being a cop in a GTA game is something that I had always wanted to do, so I went about adding in a few more things to the script I had. A few days after this, on August 5th 2009, LCPDFR was born.
