Some general questions about modding

[RD]

Dear Ludeon Community,

im a new member here and i have some questions. I just wanted to write my own mod and saw the modding page in the wiki and the tutorials here on this site. *thumbs up*

Now i got some questions. What is the difference between alpha 7 and 8 in terms of change ur mod to make it work?

Is it possible to create a building like a farm and then add another kind of building that should work as cattle gate? Is that complicated? Does s1 have some kind of tutorial that is similar or at least goes in that direction?

I saw those Tags that u have to fill in the XML file, is there a possible way to see all tags that have to be filled and which are optional?

Thx in advance
RD
