Some Input methods are specific to Controllers/Gamepads, and are useful to know for making sure your player experience caters to those who don't play on a Keyboard + Mouse.

To see if the player is using a Controller, you can check Input.UsingController

Analog Inputs

You can get direct analog inputs from the Left Stick, Right Stick, Left Trigger or Right Trigger. Keep in mind that not all Controllers have analog triggers.

float moveX = Input.GetAnalog( InputAnalog.LeftStickX );
float aimAmount = Input.GetAnalog( InputAnalog.LeftTrigger );

There is also Input.AnalogMove and Input.AnalogLook which are Vector3 and Angles respectively that automatically map to both the Keyboard + Mouse and the Left and Right Stick.

Haptics/Rumble

You can directly set the vibration intensity of each motor (and how long the vibration should last)

float leftMotor = 0.5f; // 50% intensity
float rightMotor = 0.7f; // 70% intensity
float leftTrigger = 0.2f; // 20% intensity
float rightTrigger = 0f; // No vibration
int duration = 1000; // 1000 milliseconds == 1 second

Input.TriggerHaptics( leftMotor, rightMotor, leftTrigger, rightTrigger, duration );

Or you can use one of a few presets, specifying the length, frequency and intensity

// These are optional inputs
float lengthScale = 1.2f; // 1.2x longer vibration time
float frequencyScale = 2f; // 2x vibration frequency
float amplitudeScale = 0.5f; // 0.5x as intense of a rumble

Input.TriggerHaptics( HapticEffect.HardImpact, lengthScale, frequencyScale, amplitudeScale );

You can also force all haptics to stop using Input.StopAllHaptics()

Motion Controls

If the Controller has a gyroscope or an accelerometer, then you can get motion data, otherwise it will be null.

InputMotionData motionData = Input.MotionData;
if(motionData is not null)
{
  Vector3 acceleration = motionData.Acceleration; // Accelerometer
  Vector3 angularVelocity = motionData.AngularVelocity; // Gyroscope
  // Process the data as needed...
}

Local Multiplayer

You can see how many Controllers are currently connected using Input.ControllerCount

With that count you could create a Player GameObject for each index, and then query their Inputs as normal

int playerIndex = 0; // The index of the controller this player is using

using( Input.PlayerScope( playerIndex ) )
{
  // Any input handling within this code block will only query Controller index 0
  if( Input.Pressed( "Jump" ) )
  {
    // Make Player 1 jump (or whichever index)
  }
}
