Frog, my dream would be to make a mod that would do the following types of things, centered mainly around the terrain. This is just one example but its pretty complex and without scripting and exposed events/triggers I don't see how its possible. Just curious if there is some creative way within the modding model currently available to do these types of things, or what your vision is for how FE will be moddable going forward.
Desert - You should last in desert for 2 turns unless you have water equipped in one of your three additional slots
*so i need an item property that once you equip an item it stays bound to that slot and OnTurnEnd the property of the instance of that item on the character gets decremented
water skins should be purchaseable in town
* this is easy enough
water degrades per turn in desert
* I need an event that has access to the property of the instanced waterskin item and at least IF-conidtional capability and an accesable terrain property
If you run out of water you take a huge penalty to all stats and lose health every turn
*This would be access to all of the above objects plus an End turn event that would allow me to decrement a players health as well as handle potential deaths or assign specific injuries
Maybe water spells that make water
*Pretty easy through the data
Random events like dust storm, mirage, etc that would effect a unit moving through desert.
A way to disallow mounts in swamps
and this is just the start of my list.
