AI - Japan

[unmerged(14856)]

We should add at least one or two aussie sites to the jap invasion ai.

 

[GLENN]

Haven't heard from Roxxor in a while.

If your around and still testing let us know.

I think I will try some work on the Japan ai.

 

[unmerged(14856)]

sure, I'm still around

 

[unmerged(18738)]

so where are we at with the Japan file?

 

[unmerged(14856)]

Same as always
As soon as the US works there will be the time to adjust the japanese.

In my test games the Japan ai is actually quite good at doing what it is told, it will attack all its target invasion sites and it will reinforce those sites quickly.

One other thing I've noticed about Japan, they don't seem to defend their Home Provinces as much as they should.

Here's a random idea (useful maybe for all AI nations);

Set the AI to defend provinces based on their value;

For example...

All home provinces are 1

Ports & Beaches +1

VP values, +1 per X VP (x being a number that won't destroy the concept like +1 for each 2 VP for example)

Capital +5


This could also extrapolate to non-home provinces, but I was just trying to convey my basic thoughts.

I would recommend adding a fighter parameter to the bomber section and setting the value quite high.
