How happiness works? (answer is here)

[Asmala]

I made lots of experiments and found how the happiness works. I don't know if this is already known but nobody answered to my question so I assume this is new information. Therefore I'll post this to Newbie FAQ too.

First, every new colonization (including homeworld) has 25% angry people, and that means the happiness level is Happy.

In every turn all positive and negative events are add up, round down and then added to angry level.

Every +5% in Happiness causes -0,1% and every -5% in Happiness causes 0,1% change in anger level. For example if you have +20% Happiness bonus, it's like you have two troops on your every planet.

I also noticed that homeworlds doesn't riot.

Some comments would be nice. Although this looks very simple it took very long time for me to solve it.
