Extension AIC Loader

This repository contains a module for the "Unofficial Crusader Patch Version 3" (UCP3), a modification for Stronghold Crusader.
The module is a core component of the AI support of the UCP3 and allows modifying the parameters that decide how an AI acts.

Usage

The module is part of the UCP3. Certain commits of the main branch of this repository are included as a git submodule. It is therefore not needed to download additional content.
However, should issues or suggestions arise that are related to this module, feel free to add a new GitHub issue.

Options

These options are provided to be set in the GUI:

  • failureHandling - Defines how the modules handles invalid AIC values.
    • WARN_LOG
      A warning is printed to the console and game continues.
    • ERROR_LOG
      An error is printed to the console and a message window with the error is shown. The game will continue.
    • FATAL_LOG
      An error is printed to the console and a message window with the error is shown. The game will abort.

Lua-Exports

The Lua exports are parameters and functions accessible through the module object. These are self calls and need to be called as modules.aicloader:function(...).

  • void setAICValue(aiType, aicField, aicValue, failureHandlingOverride)
    Sets a specific AIC value.
    The aiType can either be the AI slot name or the index. aicField needs to be one of the supported AIC value names and aicValue a valid value. failureHandlingOverride is optional and can be one of the values of failureHandling.
    This function is available for plugins.

  • void overwriteAIC(aiType, aicSpec, failureHandlingOverride)
    Overwrites multiple AIC values of an AI.
    Similar to setAICValue, but aicSpec is a table of aicField and aicValue pairs.
    This function is available for plugins.

  • void overwriteAICsFromFile(aicFilePath, failureHandlingOverride)
    Overwrites multiple AIC values from a file.
    The functions expects a path to a YAML-file containing an AICharacters object with AI entries of objects that need to contain a field Name and a field Personality where Name is one of the supported AI slot names and Personality is a table of aicField and aicValue pairs.
    This function is available for plugins.

  • void resetAIC(aiType)
    Resets the given AI to its default values.
    This function is available for plugins.

  • void setAICValueOverride(aicField, index, valueFunction, resetFunction)
    Overrides an already existing AIC value.
    aicField functions as an identifier for this setting, while index is the index of the real AIC value. If it is set to nil, the override is removed. valueFunction receives the value to set and needs to return the actual value to write in the form of an integer. resetFunction receives the index of the AI slot and needs to return the default value for this slot as integer.
    Not recommended to use. An index might get overridden multiple times. Try to use setAdditionalAICValue instead and handle the values in your code.

  • void setAdditionalAICValue(aicField, handlerFunction, resetFunction)
    Adds an completely new AIC value for the loader to handle.
    aicField functions as an identifier for this setting, while handlerFunction receives the AI slot index and the provided value. The actual value handling needs to happen at the side of the provider. If the handlerFunction is set to nil, the new AIC value is removed. resetFunction will always receive an AI slot index starting from 1 (Rat) to 16 (Abbot) and needs to reset the value to the default for this slot.
