Mission vs Scenario vs Map
First let's explain these 3 different concepts.
Mission
- Mission is basic unit of Nebuchadnezzar.
- It connects map and objectives together.
- Several mission together can form campaign.
- Player always play missions.
Scenario
- Scenario is just a special subset of mission.
- It's a mission which is not part of any campaign.
- Player can play any scenario without any limitation, because all scenarios are unlocked.
Map
- Map is data file containg information about specific map.
- Stuff like surface layout, buildings etc.
Create mission atom
To create new mission you have to create an atom for it first.
- In your mode create
def
folder. It will contains all def files. - In that folder create
mission.lua
file.- The name of the file is important because the type of atom is based on the def file name.
- And now let's add some content.
nature_buildings = { 'base::build.palm.1', 'base::build.palm.2', 'base::build.palm.3', 'base::build.palm.4', 'base::build.bush.1', 'base::build.bush.2', 'base::build.bush.3', 'base::build.bush.4', 'base::build.palm.bush.1', 'base::build.palm.bush.2', 'base::build.palm.bush.3', 'base::build.palm.bush.4', 'base::build.fish.1', }
- First of all, we will prepare some general variable, which we can use in multiple mission atoms.
- Beause it's always better to have shared data in some variable.
- The variable
nature_buildings
now contains all nature buildings from thebase
mod. - Notice the
base::
part when referencing atoms. You have to use it because you are referencing atoms from other mod.
irrig_buildings = { 'base::build.irrig.canal', 'base::build.irrig.pump', 'base::build.irrig.bridge.dirty', 'base::build.irrig.bridge.stone', }
- In the same way we create variable containing all irrigation buildings from the
base
mod.
mission_base = { base_mods = {"base"}, first_residents_event = 'base::event.first_residents', leaving_residents_event = 'base::event.leaving_residents', returning_residents_event = 'base::event.returning_residents', no_path_residents_event = 'base::event.no_path_residents', }
- Here we prepare variable containing data which are usable in all mission.
- We use events from the base mod.
- As well as
base_mods
property which determines from which mods the game should take available terrain data.
atom ('mission.my_first_mission', mission_base, { description = 'description.my_first_mission', intro_event = 'event.intro.my_first_mission', money_events = {}, allowed_buildings = ac( nature_buildings, ac( irrig_buildings, { 'build.road.dirty', 'build.shop.bread', 'build.farm.plant.1', 'build.warehouse.1', 'build.house.lower.1', }), allowed_monuments = {}, allowed_templates = {}, map = 'map.my_first_mission', prestige = 'prestige.my_first_mission', requests = {}, demands = {}, target_population = 300, target_prestige = 10, target_level_atoms = {'base::level.house.lower.1'}, target_level_counts = {12}, })
- And finaly we can see our new mission atom.
- Notice usage of function
ac
when defining allowed buildings.- This is helper function avilable in all def files and it can be use for arrays concatenation.
- Because not all referenced atoms are from the
base
base, we will of course have to create them before starting to work with this mission.- Look at corresponding atoms in base for inspiration.
Create map file
When we have valid mission atom, we can start to create the map itself for the mission.
- To create new map use command
new_map [atom name] [size x] [size y] empty
- We will explain empty parameter later.
- After that the game will load the mission with empty map.
