I was summoned ?
Oh yeah I see now.
Well, yeah a bit like Weishaupt, I think that question is far too generalist.
How do you make whatever_game_name_here...
Look at the game, analyze it, see what it does, break it down, process by process.
Then, yes, ask on the forum how to do such specific task or some other.
A lot of those tasks are indeed already listed in the how do I FAQ.
You can also check out the tutorials section to learn about specific and less specific tasks.
