Creating Defender type Game in Unity - 001

For the end of year show ND1 students will create simple low poly models, which will be placed in a defender style game. The creation of the script and game structure has fallen to me (Thanks Neil!!) I will post my progress and script used here so you can use any elements and see the progress.

SmoothFollow

/*
This camera smoothes out rotation around the y-axis and height.
Horizontal Distance to the target is always fixed.

There are many different ways to smooth the rotation but doing it this way gives you a lot of control over how the camera behaves.

For every of those smoothed values we calculate the wanted value and the current value.
Then we smooth it using the Lerp function.
Then we apply the smoothed values to the transform's position.
*/

// The target we are following
var target : Transform;
// The distance in the x-z plane to the target
var distance = 10.0;
// the height we want the camera to be above the target
var height = 5.0;
// How much we
var heightDamping = 2.0;
var rotationDamping = 3.0;

// Place the script in the Camera-Control group in the component menu
@script AddComponentMenu("Camera-Control/Smooth Follow")


function LateUpdate () {
// Early out if we don't have a target
if (!target)
return;

// Calculate the current rotation angles
wantedRotationAngle = target.eulerAngles.y;
wantedHeight = target.position.y + height;

currentRotationAngle = transform.eulerAngles.y;
currentHeight = transform.position.y;

// Damp the rotation around the y-axis
currentRotationAngle = Mathf.LerpAngle (currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);

// Damp the height
currentHeight = Mathf.Lerp (currentHeight, wantedHeight, heightDamping * Time.deltaTime);

// Convert the angle into a rotation
currentRotation = Quaternion.Euler (0, currentRotationAngle, 0);

// Set the position of the camera on the x-z plane to:
// distance meters behind the target
transform.position = target.position;
transform.position -= currentRotation * Vector3.forward * distance;

// Set the height of the camera
transform.position.y = currentHeight;

// Always look at the target
transform.LookAt (target);
}

Simple Move Character

var speed : float = 3.0;
var rotateSpeed : float = 3.0;

function Update () {
var controller : CharacterController = GetComponent(CharacterController);

// Rotate around y - axis
transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);

// Move forward / backward
var forward : Vector3 = transform.TransformDirection(Vector3.forward);
var curSpeed : float = speed * Input.GetAxis ("Vertical");
controller.SimpleMove(forward * curSpeed);



if (Input.GetAxis("Vertical") > 0.2)
animation.CrossFade ("WalkForward");
else
animation.CrossFade ("Idle2");

}

Camera Follow Script

Add this script to the Main Camera in your Unity Project:

var target : Transform;
var distance = 3.0;
var height = 3.0;
var damping = 5.0;
var smoothRotation = true;
var rotationDamping = 10.0;

function Update () {
var wantedPosition = target.TransformPoint(0, height, -distance);
transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

if (smoothRotation) {
var wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
}

else transform.LookAt (target, target.up);
}

Lesson 13/1/11: Example GUI Script

Example GUI Script:


var icon : Texture2D;

function OnGUI () {

// Make a background box
GUI.Box (Rect (Screen.width/2-150,Screen.height/2-75,300,200), "MAIN MENU");

GUI.Box (Rect (Screen.width/2-120,Screen.height/2-50,35,35), GUIContent(icon));

if (GUI.Button (Rect (Screen.width/2-80,Screen.height/2-50, 200, 35), "START GAME")) {
print ("Game Started");
}

GUI.Box (Rect (Screen.width/2-120,Screen.height/2-10,35,35), GUIContent(icon));

if (GUI.Button (Rect (Screen.width/2-80,Screen.height/2-10, 200, 35), "ACHIEVEMENTS")) {
print ("Achievements Started");
}

GUI.Box (Rect (Screen.width/2-120,Screen.height/2+30,35,35), GUIContent(icon));

if (GUI.Button (Rect (Screen.width/2-80,Screen.height/2+30, 200, 35), "SETTINGS")) {
print ("Settings Started");
}

GUI.Box (Rect (Screen.width/2-120,Screen.height/2+70,35,35), GUIContent(icon));

if (GUI.Button (Rect (Screen.width/2-80,Screen.height/2+70, 200, 35), "CREDITS")) {
print ("Credits Started");
}
