I recently began trying to download the custom made entity (made by Scottie and Moth) from this: https://developer.valvesoftware.com/wiki/Bumbleball#Installation
But I have absolutely no idea what to do! The instructions suck, to say the least. I downloaded the file from here like I was supposed to: http://forums.thinkingwithportals.com/downloads.php?view=detail&df_id=1377
Then I had to download something that opens up 7z files, then I followed the installation process.
Step 1: Put the materials, sounds and models folder to Steam\steamapps\common\portal 2\portal2\
There was no "sounds" folder inside of the BumbleBall folder. So I just put the materials and models folders there instead, wasn't sure if I was supposed to over-write the already existing models and materials folders, but I did it anyways because I had no choice.
Step 2: Put the Instances folder to Steam\steamapps\common\portal 2\sdk_content\maps\instances\
This one was pretty strait forward, and miraculously it worked. However, it does not show up in there in Hammer.
Now I followed (as best I could) the instructions for the "Usage"
1. Create a new func_instance
2. For the Vmf Filename' select your downloaded instance vmf's
Took about half-way into writing this Discussion for me to figure out what that meant, mostly because the Instances file I put in the other Instances file wasn't there. So I had to go to the Desktop, and open up the BumbleBall folder, go to Instances, Scottie, and then Bumbleball.vmf.
Didn't do anything.
3. Give it a Fix Up Name
This is when I decided to make a Discussion.
