Techs

The Techs module manages technologies - research items that trigger effects when completed.

Quick Example

from aoe2_genie_tooling import GenieWorkspace

workspace = GenieWorkspace.load("empires2_x2_p1.dat")

# Get the tech manager
tech_manager = workspace.tech_manager

# Get an existing tech
loom = tech_manager.get(22)
print(f"Loom research time: {loom.research_time}")

# Create a new tech
tech = tech_manager.create("Super Upgrade", effect_id=500)
tech.research_time = 60
tech.set_cost(0, resource_id=0, amount=100)  # 100 food

Overview

TechManager (workspace.tech_manager)

The manager handles tech CRUD operations:

Method	Description
get(tech_id)	Get a TechHandle
create(name, effect_id)	Create a new tech
copy(source_id)	Copy a tech
delete(tech_id)	Delete a tech
exists(tech_id)	Check if tech exists
find_by_name(name)	Find by name
count()	Total tech slots

TechHandle

The handle provides attribute access and configuration:

Key Attributes:

• name, effect_id, research_time
• icon_id, button_id
• civilization_id, min_required_techs

Collections:

• costs - Resource costs (3 slots)
• required_tech_ids - Prerequisites (6 slots)
• research_locations - Where it's researched

---

Creating Techs

tech_manager = workspace.tech_manager

# Basic creation
tech = tech_manager.create("My Tech")

# With linked effect
tech = tech_manager.create("My Tech", effect_id=500)

# At specific ID
tech = tech_manager.create("My Tech", tech_id=800)

---

Linking Effects

Techs trigger effects when researched:

# Create effect first
effect_manager = workspace.effect_manager
effect = effect_manager.add_new("My Effect")
effect.add_command.attribute_modifier_add(a=4, b=0, c=-1, d=10)

# Link to tech
tech = tech_manager.create("My Research")
tech.effect_id = effect.id

See Effects for effect configuration.

Setting Costs

# 3 cost slots available
tech.set_cost(0, resource_id=0, amount=200)  # 200 food
tech.set_cost(1, resource_id=3, amount=150)  # 150 gold
tech.set_cost(2, resource_id=1, amount=100)  # 100 wood

---

Setting Prerequisites

# 6 requirement slots
tech.set_required_tech(0, tech_id=101)  # Castle Age
tech.set_required_tech(1, tech_id=22)   # Loom

# How many must be researched
tech.min_required_techs = 2  # Both required

---

Research Locations

# Add where tech can be researched
tech.add_research_location(unit_id=103, button_id=5)  # Blacksmith
tech.add_research_location(unit_id=209, button_id=8)  # University

See Research Locations for details.
