This is a project for editing parts of an 'aoe2scenario' file from Age of Empires 2 Definitive Edition
Project description
AoE2ScenarioParser
This is a project for editing parts of an aoe2scenario
file from Age of Empires 2
Definitive Edition outside of the in-game editor.
Progress
Current up-to-date progress can be found on the Trello board.
Features:
- Reading
aoe2scenario
files from AoE2:DE (Check supported versions below). - Writing said file back to an
aoe2scenario
file. - Triggers
- View (Specific or all) Triggers, Conditions and Effects.
- Adding Triggers, Conditions and Effects.
- Editing Triggers. (Only adding Conditions and Effects is currently supported)
- Deleting Triggers.
Bugs:
- None...? Surely not!?.
Please report any bugs you find to the github issue board.
Support:
This repository supports the DE
scenario versions:
- 1.36
- 1.37 (Game update: 35584)
Installation
Run the following pip command for installation:v
pip install AoE2ScenarioParser
Usage
DISCLAIMER: NO SYNTAX OR STRUCTURE IS SET IN STONE AND COULD CHANGE AT ANY TIME
Getting Started
To start, import the main AoE2Scenario
class from the module:
from AoE2ScenarioParser.aoe2_scenario import AoE2Scenario
You can also import datasets for ease of use (more below):
from AoE2ScenarioParser.datasets import effects
from AoE2ScenarioParser.datasets import conditions
Define the file you will be reading and the path you will be writing to.
Note: Creating folders isn't supported at this time. Please use an existing folder.
# It is recommended to not overwrite your file. This way you can keep a backup!
input_path = "File/Path/To/Your/Input/File"
output_path = "File/Path/To/Your/Output/File"
Now create the object with the filename as parameter.
scenario = AoE2Scenario(input_path)
You can retrieve access to the triggers using the object_manager.
trigger_manager = scenario.object_manager.get_trigger_manager()
Adding triggers
Now the best part, adding triggers! You can add triggers easily. You can change all parts of the trigger using functions (type "trigger." and the autocomplete will show you a list of options.). Eventually, there will be a API docs.
trigger = trigger_manager.add_trigger("Trigger :)")
trigger.description = "This is a great description!"
To add conditions or effects, just call the method add_condition
and add_effect
. You can use the dataset to figure give the function the right ID. If you're unsure about what parameters are available in every trigger, check the docs of the condition. Click on conditions.chance
and show the docs (CTRL + Q in PyCharm). It will show you: "Parameters for the chance condition are: amount_or_quantity". Now use the attribute amount_or_quantity
to apply the right value.
The example shows: A trigger with 25% chance of showing a message.
condition = trigger.add_condition(conditions.chance)
condition.amount_or_quantity = 25
effect = trigger.add_effect(effects.display_instructions)
effect.player_source = 1
effect.display_time = 11
effect.message = "This message was set using AoE2ScenarioParser!"
Viewing triggers
Tip: As you know you can change the order of triggers in the in-game editor (Not officially supported with this package (yet)). When using the view, edit and delete functionality you can choose to select a trigger by index
or by display_index
. display_index
is the index in which the triggers are shown in the in-game editor. The index
is the index in which they were created. Both start from 0.
There's multiple ways to check out triggers and their contents. When editing or deleting a trigger you'll need an index. This can be the actual index or the display index.
You can use the following function to generate a simple overview of the triggers.
trigger_manager.get_summary_as_string()
# This returns the following (As String):
Trigger Summary:
Init Trigger [Index: 0, Display: 0] (conditions: 2, effects: 1)
Spawn Wave 1 [Index: 1, Display: 1] (conditions: 2, effects: 7)
Spawn Wave 2 [Index: 2, Display: 2] (conditions: 1, effects: 7)
If you want to know all specifics about a trigger you can use the functions below.
trigger_manager.get_trigger_as_string(trigger_id=0)
trigger_manager.get_trigger_as_string(display_index=0)
# You can also request the id from a trigger object:
trigger_manager.get_trigger_as_string(trigger_id=trigger.trigger_id)
# These functions return the following (As String):
'Init Trigger' [Index: 0, Display: 0]:
enabled: True
looping: False
description: 'This is the initialisation trigger. '
conditions:
timer:
timer: 5
inverted: 0
variable_value:
amount_or_quantity: 1
inverted: 0
variable: 0
comparison: 0
effects:
activate_trigger:
trigger_id: 1
You can also use this function to generate the above string but for all triggers at once.
trigger_manager.get_content_as_string()
Editing or removing triggers
When opening a file that already contains triggers you might want to edit or even remove said triggers. Please note that it's not possible to remove specific conditions or effects (yet).
You can edit a trigger like so:
trigger = trigger_manager.get_trigger(trigger_id=0)
trigger = trigger_manager.get_trigger(display_index=0)
trigger.name = "New Trigger Name"
trigger.description = "Awesome New Description!"
For removing it basically works the same:
# Remember to save to a different file. Especially when removing triggers.
trigger_manager.delete_trigger(trigger_id=0)
trigger_manager.delete_trigger(display_index=0)
Datasets (Buildings, Units and Techs... etc.)
The project currently contains 6 datasets. These are currently pretty basic and only contain the in-editor options. The following datasets are included in the project:
- conditions
- effects
- buildings
- units
- techs (technologies)
- terrains (Not very usefull atm)
You can use them like so:
from AoE2ScenarioParser.datasets import techs, units, buildings
# Techs
techs.loom # 22
techs.imperial_age # 103
# Units
units.archer # 4
units.man_at_arms # 75
units.cannon_galleon # 420
# Buildings
buildings.krepost # 1251
buildings.wonder # 276
You can also use strings to get the IDs
techs.get_tech_id_by_string("loom") # 22
units.get_unit_id_by_string("man_at_arms") # 75
buildings.get_building_id_by_string("farm") # 50
Security note:
These functions are implented for ease of use. Not security. They use eval()
and should not be used in any server environment where others have access to the input of these functions. For more information please check out this Stack Overflow answer.
Of course, you can combine that with triggers
like so:
trigger = triggers.add_trigger("Create Man@Arms")
effect = trigger.add_effect(effects.create_object) # effects dataset
effect.object_list_unit_id = units.man_at_arms # units dataset
effect.player_source = 1
effect.location_x = 6
effect.location_y = 9
Saving
When you are done, you can write all your progress to a file like so:
scenario.write_to_file(output_path)
Please remember to use a different path (filename) than your input file. This way you have a backup file incase you encounter a bug.
