Adding Achievements to your Portal 2 Mod !

This guide will show you how to add achievements to your Portal 2 Mod without the Portal 2 source code.

Explanations

First, you should know that there are limitations, you are limited to 51 achievements, the 51 of Portal 2. Why? Because we are going to use the API name of the already existing Portal 2 achievements and simply change the title and description in your Steamworks to create your own Portal 2 mod achievements !

Setting up your achievements in Steamworks

In your achievements section in Steamworks, you need to add your custom achievements:

API Name	Name	Description	Determined by	Is Hiden ?	Unlocked Icon	Locked Icon
<An already existing API name from Portal 2 ( listed here [steamdb.info] )>	<Your own achievement name>	<Your own achievement description>	Client	<Your choice>	<Your icon>	<Your icon>

Here's an exemple :

Now publish your update and you will see your achievement in your game library.

Setting up your achievement in Hammer

Now, go to hammer and create a logic_achievement.
In the logic_achievement parameters, set a name for triggering the achievement, and an achievement name with the API name of your achievement :
Once it's done, create an output to an object to trigger the achievement (in my case I choose the logic_auto to trigger the achievement on the start of the map) :
Now, compile your map and update your game via Steampipe and Steamworks.

See if it works!

Now, open your game and see if the achievement is unlocked when triggering it !
