Well, I usually put my files into the base folder of blockland before i package them up.
You usually have to restart blockland so the new file will be recognized when you first create it, but alternatively you can type
setmodpaths(getmodpaths());So open up blockland, make a file in your base folder called Test.cs, put that hello world code inside of it and save.
Now switch back to blockland and open the console and type this.
setmodpaths(getmodpaths()); exec("base/test.cs");It should say
Executing base/test.cs.Then simply call your function from the console and it should work.
To package your add-on, you will have to put it into a client_test.zip with a description, namecheck, and a client.cs which can either contain the test code and you wont need another .cs file, or make it execute the test code which requires another .cs file.
This is an example of how a packaged add-on should look, take a look at the client.cs file inside of it (this is a client sided add-on).
