Project description

AoE2ScenarioRms

Add replay-ability to scenarios through random resource placement using triggers & XS! A library built on top of the AoE2ScenarioParser.

Keep in mind this project is a work-in-progress

Installation

You can install the project using pip:

pip install AoE2ScenarioRms

Updating AoE2ScenarioRms

If you have the library already installed, you can use the following command to update it:

pip install --no-cache-dir --upgrade AoE2ScenarioRms

To read about the changes between versions, checkout the CHANGELOG.md file.

How to get started

For examples, see the Examples header.

1. AoE2ScenarioRms

The first thing you do is wrap a AoE2DEScenario object from the AoE2ScenarioParser.
For more info on the AoE2ScenarioParser, click here.

from AoE2ScenarioParser.scenarios.aoe2_de_scenario import AoE2DEScenario
from AoE2ScenarioRms import AoE2ScenarioRms
...
scenario = AoE2DEScenario.from_file("<file-path here>")
asr = AoE2ScenarioRms(scenario)

Now AoE2ScenarioRms can access the scenario and start adding triggers and XS to it for random resources!

2. Clearing the scenario

When you have a scenario that you want filled with random resources, it makes sense you'd want the scenario to not contain any resources to begin with. You can clear these using the ScenarioUtil.clear(...) functionality.

For example, if you want to clear absolutely everything that can be cleared, you can do the following:

from AoE2ScenarioRms.util import ScenarioUtil
from AoE2ScenarioRms.flags import ObjectClear
...
ScenarioUtil.clear(scenario, ObjectClear.ALL)

Above you can see ObjectClear.ALL being used. This is quite a nuclear option, it might clear more than you want.
Below is a list of things that can be cleared (and thus which ObjectClear.ALL clears).

ObjectClear.PLAYERS - Remove all player related object (TCs, villagers, scouts etc.)
ObjectClear.BOARS - Remove all boar-like units (e.g. Boar, Elephant, Rhinos...)
ObjectClear.SHEEP - Remove all sheep-like units (e.g. Sheep, Goat, Turkey...)
ObjectClear.DEER - Remove all deer-like units (e.g. Deer, Zebra, Ibex...)
ObjectClear.WOLFS - Remove all wolf-like units (e.g. Wolf, Crocodile, Lion...)
ObjectClear.GOLDS - Remove all gold mines
ObjectClear.STONES - Remove all stone mines
ObjectClear.BUSHES - Remove all berry and fruit bushes
ObjectClear.STRAGGLERS - Remove all trees not on tree terrain
ObjectClear.RELICS - Remove all relics
ObjectClear.CLIFFS - Remove all cliffs
ObjectClear.DEEP_FISH - Remove all types of deep fish (including Dolphin and Great Marlins)
ObjectClear.SHORE_FISH - Remove all shore fish and box turtles

There are also combinations of the above for ease of use:

ObjectClear.ANIMAL_OBJECTS = BOARS + SHEEP + DEER + WOLFS
ObjectClear.FISH_OBJECTS = DEEP_FISH + SHORE_FISH
ObjectClear.RESOURCE_OBJECTS = GOLDS + STONES + BUSHES + STRAGGLERS + RELICS
ObjectClear.ALL = Everything listed above

The object ObjectClear is a Flag object. This object has some special properties:

You can combine them using X | Y: ObjectClear.STONES | ObjectClear.GOLDS
- This would clear all stone and gold tiles.
You can exclude an option from a combination using X & ~Y: ObjectClear.ALL & ~ObjectClear.CLIFFS
- This would clear everything listed above except cliffs.

So, to clear all animal objects but leave wolfs and also clear relics use the following:

from AoE2ScenarioRms.util import ScenarioUtil
from AoE2ScenarioRms.flags import ObjectClear
...
object_clear = (ObjectClear.ANIMAL_OBJECTS & ~ObjectClear.WOLFS) | ObjectClear.RELICS
ScenarioUtil.clear(scenario, object_clear)

More info about Flag objects can be found on the Python docs.

3. GridMap

The spawning of objects (units, resources etc.) works by first creating a so called GridMap.
A GridMap is used to store on which tiles the objects can (or cannot) spawn.
For example, you can 'tell' a GridMap to only allow the spawning of objects on water terrains.

You can create a GridMap using the GridMapFactory like so:

from AoE2ScenarioRms.util import GridMapFactory

...
GridMapFactory.select(...)  # Or
GridMapFactory.block(...)

The select and block functions can be used to either select certain tiles, or... to block them.
Selecting tiles means an object can spawn on them and on nothing else, blocking them means the object cannot spawn on the tiles, but they can on all others.

So, to follow the example above of only allowing spawning on water tiles you can do the following:

from AoE2ScenarioParser.datasets.terrains import TerrainId
from AoE2ScenarioRms.util import GridMapFactory

...
grid_map = GridMapFactory.select(
    scenario=scenario,  # The `scenario` from AoE2DEScenario.from_file(...)
    terrain_ids=TerrainId.water_terrains()
)

This takes all types of water from a dataset in the AoE2ScenarioParser and adds them as terrain_ids.
The function used is select(...) which means all objects you spawn with this GridMap will be spawned on water tiles.

The following methods of selecting which tiles to spawn objects on can be used:

Attribute	Description
`terrain_ids`	(As seen above) - A `list` of terrain IDs to select/block. Terrain Ids
`terrain_marks`	A Flag that has 'shortcuts' to certain terrain aspects on a map. TerrainMarks
`object_marks`	A Flag that has 'shortcuts' to certain object aspects on a map. ObjectMarks
`object_consts`	A `dict` of object consts as keys and a distance as value that to select/block around the given objects. Object consts
