Inspired by UO Loop, MacroUO is a simple third party macro utility for Ultima Online. I am still maintaining it because a lot of people I know are still playing Ultima Online and, over the past years, it became very popular on some servers.

MacroUO is platform-agnostic, therefore it can be used on both x86 and x64 environments. The solution model targets Visual Studio 2017 and the projects are compiled under .NET Framework 4.7.1, therefore it can run on every machine equipped with Windows 7 or greater.

Two different interface options can be toggled on and off through the menu bar. The TopMost option forces the MacroUO window to overlap all the other windows, even when it's not active. The Transparency option makes the MacroUO window slightly transparent.

The Scan button analyses running processes in order to identify active Ultima Online clients. Only the clients on which an account has been successfully authenticated will show up.

The purpose of the dropdown menu is to select the target client on which the selected macro will be executed.

This panel holds the macro settings. The Key dropdown sets the keyboard key to send to the target client. The Delay control sets the delay (in milliseconds) between each macro execution. The key modifiers can be turned on and off using their respective checkboxes. A limit to the number of executions can be set through the Runs control: MacroUO will automatically stop once the specified limit has been reached.

On the bottom right of the panel there are two counters: the first one records how many times the current macro has been executed, the second one keeps track of the elapsed time since the start of the process. Pushing the Reset button will immediately reset both counters.

The purpose of this panel is to manage the preset macros stored in the Presets.xml file. The dropdown menu loads the selected preset into the Macro panel. The Add button, enabled only if no preset is selected, creates a new preset (with a default name) from the current macro settings. The Remove button deletes the currently selected preset. The Reload button forces MacroUO to reload the preset macros from the Presets.xml file.

While a preset is selected in the dropdown menu:

• changing the Macro panel settings modifies the active preset;
• pushing F2 opens up a dialog that allows to rename the active preset (the name must be unique and composed of alphanumeric characters separated by single white-space characters).

All the changes to the preset macros are automatically saved when MacroUO is closed.

On the bottom of the window there are three buttons. The Start button activates the process that executes the specified macro on the target client, while the Stop button interrupts it. The Collapse button reduces the MacroUO window size, while the Expand button restores it.

The classes are completely undocumented and the code contains no descriptive comments; I know it's bad practice, but I really don't have time to create a proper documentation for this project. Nonetheless, everything should be pretty straightforward since it's just a simple form with a few buttons.

The following method (which can be found within the ApplicationDialog class) identifies active Ultima Online clients on which macros can be executed:

private Boolean EnumerateWindow(IntPtr windowHandle, IntPtr lParameter)
{
	String windowClass = NativeMethods.GetWindowClass(windowHandle);

	if (!windowClass.Contains("Ultima Online"))
		return true;

	String windowText = NativeMethods.GetWindowText(windowHandle);

	if (!windowText.Contains("Ultima Online - "))
		return true;

	UInt32 windowThreadId = NativeMethods.GetWindowThreadId(windowHandle);

	m_Clients.Add(new Client(windowText, windowHandle, windowThreadId));

	return true;
}
