Is there a simple way to get a country to be ready for war (by massing armies on the border with the countries it will invade)? I tried using ai_prepare_war but that causes the ai to declare war when all I want is for them to mass up troops on a specific axis of advance in preparation for an event-triggered war. I know you can set specific units to move to specific provinces, but that's a bit too time consuming with large armies and I want it to take into account the units that will be produced after the game starts. The ai tends to get steamrolled because it can't pre-plan a war.
Making an ai file would be something I'd like to avoid; I just want the ai to put its soldiers against specific borders.
Rules how to garrison borders are defined into the garrison = { ... } AI setting. You should either set these into the default AI file loaded on scenario start (and make sure no unwanted garrison settings are loaded later by AI switch) or make an AI file that to be switched to by event. As you can see both cases involve AI files modding as a minimum.
Is there a fix to the problem where pictures show up in negative in event boxes? Tried everything, sometimes it works but then on the next play test reverts to being negative.
Old trick that usually works for me is to make a copy of a working in the game picture, open it in MS paint, paste over the image I want to use and save without changing file format. Then all you have to do is to rename that file as you like.
