Multi-hex fire groups is difficult to implement from interface and AI perspective, this feature is not in my future scope at the moment.
This is one of the most disappointing news I read on this forum. Multi-hex fire groups are a core feature of the game that inspired ToTH. The "don't stack, but form firegroups" is the most basic tactics one must learn with it.
The whole game has been balanced in years taking into account that, and forcing to stack to increase FP, will unbalance everything in favor of the force that has the more/better leaders ( Germany, usually ), because they can use leader modifiers to balance somewhat the increased risk of damage when receiving fire as a stack. It changes the game entirely.
There's no need for big changes to the UI. A possible way of doing it would be:
- Before resolving a fire attack, the program might check all adjacent friendly units that are still allowed to fire, and display a message box like this:
"Do you want to attack as a fire group with units in hexes XX, YY and ZZ ?"
And all the user would have to do, is to reply YES or NO.
This change would not require ANY change to the UI, except for the added dialog box.
The AI might just use the strategy of always trying for fire groups, if possible, so it will also work as a teaching tool for good tactics. Or, it might use multi-hex fire groups at the highest difficulty settings only, and continue as it is now, at the lowest settings.
