To affect things in space, you often want to activate a module of your ship. This guide shows how to make your bot do this.

If you want to select a target first, see the guide on how to select a target.

To activate a module in eve online, we toggle the module when it is inactive. With this approach, the task of activating the module is divided into the following two subtasks:

  • Check if the module is active
  • If it is not yet active, toggle the module

How to Check If a Module Is Active

All your ships visible modules are represented in Sanderling.MemoryMeasurementAccu?.Value?.ShipUiModule.
To check whether a module is active, pick its representation from there then use it’s property RampActive to determine activity.
The following sample code demonstrates this:

var shipModule = Sanderling.MemoryMeasurementAccu?.Value?.ShipUiModule?.FirstOrDefault(); 

Host.Log("Module is " + ((shipModule?.RampActive ?? false) ? "active" : "inactive"));

How to Make Your Bot Toggle a Module

A module can be toggled by clicking on its representation in the ship UI.
To make a bot do this, we use our module representation from Sanderling.MemoryMeasurementAccu?.Value?.ShipUiModule to click on, using the left mouse button.
This can be done using the following code:

Sanderling.MotionExecute(shipModule.MouseClick(MouseButtonIdEnum.Left));

Solution to Activate a Module

After learning how checking for activity and toggling works, we can combine those two into one code to activate a module.
Since the toggle should only happen when the module is not already active, we use an if-statement to branch on this condition.
Below you see the complete code to activate a module, also containing the if-statement:

var shipModule  = Sanderling.MemoryMeasurementAccu?.Value?.ShipUiModule?.FirstOrDefault(); 

if(!(shipModule?.RampActive ?? false))
	Sanderling.MotionExecute(shipModule.MouseClick(MouseButtonIdEnum.Left));
