Challenge tasks ACHIEVEMENTS using cheats to make easy

Cheat for achievement challenge tasks using only console
This is a way to get the Portal challenge achievements with a cheat but here's the twist, it doesn't disable achievements!
This method uses the ent_fire command in console. If you do not know how to get the developer console then please look in the comments or search how to.

How to enable dev console:
Options >>>
Keyboard >>>
Advanced Settings (in the bottom of the window)
Enable Developer Console

Requirements

• The developer console enabled
  
• Basic knowledge of the maps
  
• Ability to decipher my terrible guide

Step 1: The playthrough

To start all you have to do is play the map normally and don't worry about your score as that will be reset.

For this I will play Testchamber 13

Playing the map normally, you can see how my step counter goes up to very high levels.

Step 2: The Code

Head towards the exit elevator but don't go in it. Step through the particle field though.
Open the developer console with the tilde key (usually below the Esc key)

` ¬

Type this code in


"ent_fire !picker resetplayerstats"


You must be facing the elevator and be past the particle field.

Step 3: Success

You've completed it. Just walk into the elevator and soon you'll have all gold challenge medals allowing for 100% completion of the game.

(Notice: I've tried this on all challenges and it works perfectly for my 100% achievements. Please check the comments for questions as they likely have already been asked.)

Extra infomation

If your achievements in-game are not up to date to steam then delete the gamestate.txt file in your Portal directory.

After 5 years, I finally decided to fix this section.



Start a challenge map as normal.







Play through the map until you get to the end elevator.



Before entering the elevator, stop and look in a way similar to what I do.

(You should be after the shield but before getting in the elevator)



Open the console and type the command in the screenshot.

(You'll know that it's working if "resetplayerstats" appears as one of the options in the dropdown menu.)

Still working, this isn't patched till feb/24.
Remember, first you gotta put "ent_fire !picker resetplayerstats" without the quotes to work!

Thanks king. The steps and time are fucking awful and aren't puzzles at all, especially the steps because the tracking is ass, the least portals is actually fun to figure out

[Bugz]

For everyone saying, SAM doesn't update the achievements page in source games.

[madvillain]

This is patched, much more reliable method
