I guess I have receved so much from this forum that it would be nice to give back some. This are very simple scripts whcih I reuse a lot and might come in handy. One is an aspect correction script and another is a action to make a guilayer fade in and out when a certain button is pressed.
//Aspect Correction Script for Unity - Zerofractal 2006
//This script can be placed on any GUI element to make its aspect correct to 1:1.
//The scale is based on the height of the element.
//It works with textures of equal or unequal width and height, such as 1024x512 maps.
//Unlike other scripts, this one takes the aspect from the actual screen making it useful for 4:3 16:9 etc etc.
function Awake() {
RefreshAspect();
}
function RefreshAspect() {
var aspect: float = 1/Camera.main.aspect;
transform.localScale.x = transform.localScale.y * aspect * guiElement.texture.width/guiElement.texture.height;
transform.position = transform.localPosition;
}
The other is a FadeIn Script:
var buttonName="Jump";
var fadeDuration:float=0.5;
var initialDelay:float=5;
private var timeLeft:float=0.5;
function Awake () {
timeLeft = fadeDuration;
}
function Update () {
if (initialDelay > 0){
initialDelay = initialDelay-Time.deltaTime;
} else {
if (Input.GetButton (buttonName))
fade(true);
else
fade(false);
}
}
function fade(direction:boolean){
var alpha;
if (direction){
if (guiElement.color.a < 0.5){
timeLeft = timeLeft - Time.deltaTime;
alpha = (timeLeft/fadeDuration);
guiElement.color.a=0.5-(alpha/2);
} else {
timeLeft = fadeDuration;
}
} else {
if (guiElement.color.a > 0){
timeLeft = timeLeft - Time.deltaTime;
alpha = (timeLeft/fadeDuration);
guiElement.color.a=alpha/2;
} else {
timeLeft = fadeDuration;
}
}
}
Neat. Is there any reason these can’t go on the wiki? It would be nice to have a single place to access this stuff, so people can appreciate it and modify it more easily :).
I don’t suppose that while you’re in the sharing mood, that you could share your secrets to the rotating select menu that you’re using in your Prism Menu?
Well the rotating menu is not that much of a secret. In fact is very simple.
A water plane, a noise script to give some nice mood to the camera, and a script that rotates the menu. Beware, I’m not that much of a programmer. But it basically adds a state variable (rotating), a current angle (ang), a ang Interval, which is derived from 360 degrees/the number of items.
It was a pain in the ass to put together, the script goes something like this…:
function Update () {
if (not rotating) {
if (Input.GetAxis ("MenuNav") > 0.25){
direction = true;
if ((ang + angInterval) == 360){
ang = 0;
} else {
ang = ang + angInterval;
}
rotating = true;
}
if (Input.GetAxis ("MenuNav") < -0.25) {
direction = false;
if ((ang - angInterval) == angInterval*-1){
ang = 360-angInterval;
} else {
ang = ang - angInterval;
}
rotating = true;
}
if (Input.GetButton ("MenuChoose")) {
Application.LoadLevel ((ang/angInterval)+2);
}
}
if ((rotating) (itemTextures.Length > 1)){
var newAng;
if (direction){
newAng = zfMenu.transform.localEulerAngles.y + Time.deltaTime*speed;
if ((newAng < ang) || (ang == 0 newAng >(360-angInterval))){
zfMenu.transform.Rotate(0, Time.deltaTime*speed, 0);
} else {
rotating = false;
zfMenu.transform.localEulerAngles.y = ang;
}
} else {
newAng = zfMenu.transform.localEulerAngles.y - Time.deltaTime*speed;
if ((newAng < 0) (ang != 0)) {
newAng = 360 -Time.deltaTime*speed;
}
if ((newAng > ang)) {
zfMenu.transform.Rotate(0, Time.deltaTime*speed*-1, 0);
} else {
rotating = false;
zfMenu.transform.localEulerAngles.y = ang;
}
}
}
}
