You can use a mouse for position information or its button states. In the control system you create an instance of type Mouse Input.
It is also possible to check for mouse input in the safety system by means of critival inputs. Defining a Mouse Input the HAL will contain 3 registered mouse button inputs under the names of:

1. leftMouseButton
2. middleMouseButton
3. rightMouseButton

As an example you could define a critical input in the safety system as follows

  Input<bool>* in1 = HAL::instance().getLogicInput("leftMouseButton", false);
  criticalInputs = { in1 };

You can use a XBox controller for position information or its button states. In the control system you create an instance of type XBox Input.
It is also possible to check for mouse input in the safety system by means of critival inputs. Defining a Mouse Input the HAL will contain 3 registered mouse button inputs under the names of:

1. leftMouseButton
2. middleMouseButton
3. rightMouseButton

As an example you could define a critical input in the safety system as follows

  Input<bool>* in1 = HAL::instance().getLogicInput("leftMouseButton", false);
  criticalInputs = { in1 };
