AimDownSights

[edit] Description

This script will make a generic first person shooter seem more modern by allowing you to hold a key to aim down the sights.
While the key is held it slows down moving and turning speeds and smoothly adjusts the x and y position of the gun as well as the field of view of the camera.

[edit] Usage

• Place your gun model as a child of the Main Camera in the default FPSWalker. It's position should be x(0.5), y(-0.4), and whatever z position looks best.
  • You may want to adjust the scale of your model to whatever looks best in this position as well.
• Set up an input button named "Sights". You can map this to whatever key or mouse button you want. Mine is set to left shift.
• Attach the following script to the First Person Controller.
  • Drag your gun model (child of the main camera) into the slot for "Gun" on the script.

[edit] Script

var nextPos = 0.0;
var nextField = 40.0;
var nextPos2 = -0.2;
var dampVelocity = 0.4;
var dampVelocity2 = 0.4;
var dampVelocity3 = 0.4;

   var newPos2 = Mathf.SmoothDamp(gun.transform.localPosition.y, nextPos2, dampVelocity3, .3);
   
   gun.transform.localPosition.x = newPos;
   gun.transform.localPosition.y = newPos2;
   Camera.main.fieldOfView = newField;
   
   if (Input.GetButton("Fire2")) {
       //adjust viewpoint and gun position
       nextField = 40.0;
       nextPos = 0.0;
       nextPos2 = -0.2;
