Weapon pickup mod [GTA3]

Recently started playing in GTA III. And the first thing I started was studying scripting in this game. But I did not find textbooks on the Internet, and nobody knows any of the familiar scripting in the top three, so I started studying scripting myself. To be more precise, this is the third script. I did not start the first two scripts. This script I decided to post, because similar I did not find on the site.
The script adds to the island of Portland 4 places where you can get a lot of weapons. I apologize if I made mistakes in the names of the districts. I started playing GTA 3 quite recently.
1. In the "red light district". Where the first dwelling of Claude is.
2. Near the Ammunition, near the Loudea Club.
3. Behind the police station.
4. Near the "Bistro St. Mark."
Due to the limit with local variables (maximum 17), I divided the mode into two scripts. Global variables I do not use.

The script is not the first. My first two scripts were very simple. Judge as you see fit. Although, maybe I just helped the knowledge of scripting in Sa, but nevertheless, the script was given to me with difficulty. The script will be useful to those who start the game from the beginning.
