have problem in OntriggerEnter (with different objects) with GUItexture

Questions & Answers
1

Hello, Im new here, with Unity 3D as well, Im doing some script to let the user interact with 8 planets of the solar system. All I want is: when the user enter 1 planet, the GUItexture (which is show the Photo of that planet) is on and the sound of plannet play. When the person enter the 2nd time, the Guitexture is Off.

Im trying to code and Add into the Guitext (which is called PlanetCollect):

static var planet : int = 0;
var Jupiter : Texture2D;
var Earth : Texture2D;
var Neptune : Texture2D;
var Saturn : Texture2D;
var Mercury : Texture2D;
var Venus : Texture2D;
var Mars : Texture2D;
var Uranus : Texture2D;

function Start(){
    guiTexture.enabled = false;
    planet = 0;
}

function Update () {
        if(planet == 1){
    guiTexture.texture = Jupiter;
    guiTexture.enabled = true;
    }
        else if (planet == 2){
    guiTexture.texture = Earth;
    guiTexture.enabled = true;
    }
        else if (planet == 3){
    guiTexture.texture = Neptune;
    guiTexture.enabled = true;
    }
        else if (planet == 4){
    guiTexture.texture = Saturn;
    guiTexture.enabled = true;
    }
        else if (planet == 5){
    guiTexture.texture = Mercury;
    guiTexture.enabled = true;
    }
        else if (planet == 6){
    guiTexture.texture = Venus;
    guiTexture.enabled = true;
    }
        else if (planet == 7){
    guiTexture.texture = Mars;
    guiTexture.enabled = true;
    }

        else if (planet == 8){
    guiTexture.texture = Uranus;
    guiTexture.enabled = true;
    }
}

Then I creat another one called PlayerCollisions.Js. And add into First Person Controller:

var JupiterCollect : AudioClip;
var EarthCollect : AudioClip;
var NeptuneCollect: AudioClip;
var SaturnCollect : AudioClip;
var MercuryCollect : AudioClip;
var VenusCollect : AudioClip;
var MarsCollect : AudioClip;
var UranusCollect : AudioClip;

function OnTriggerEnter(collisionInfo : Collider){
    if(collisionInfo.gameObject.tag == "jupiter"){
        JupiterCollect.planet=1;
        audio.PlayOneShot(JupiterCollect);

}
    else if(collisionInfo.gameObject.tag == "earth"){
        EarthCollect.planet=2;
        audio.PlayOneShot(EarthCollect);
    } 
    else if(collisionInfo.gameObject.tag == "neptune"){
        NeptuneCollect.planet=3;
        audio.PlayOneShot(NeptuneCollect);
    }
    else if(collisionInfo.gameObject.tag == "saturn"){
        SaturnCollect.planet=4;
        audio.PlayOneShot(SaturnCollect);
    }
    else if(collisionInfo.gameObject.tag == "mercury"){
        MercuryCollect.planet=5;
        audio.PlayOneShot(MercuryCollect);
    }
    else if(collisionInfo.gameObject.tag == "venus"){
        VenusCollect.planet=6;
        audio.PlayOneShot(VenusCollect);
    }
    else if(collisionInfo.gameObject.tag == "mars"){
        MarsCollect.planet=7;
        audio.PlayOneShot(MarsCollect);
    }
    else if(collisionInfo.gameObject.tag == "uranus"){
        UranusCollect.planet=8;
        audio.PlayOneShot(UranusCollect);
    }

else
    planet=0;
}

And the 8 var jupiter, earth... have errors is: unknown Identifier and 'planet' is not a member of 'UnityEngine.AudioClip'

nevermind, i found out what was wrong. in the second code, it says something.planet = 1; right? well, the var to explain that identifier is in your other script, so you have to make it a static var for another script to recognize it.

Your first script is named PlanetCollect, right? I think you want the conditional statements in the PlayerCollision script to read: 

if(collisionInfo.gameObject.tag == "jupiter"){
        PlanetCollect.planet=1;
        audio.PlayOneShot(JupiterCollect);
} else if(collisionInfo.gameObject.tag == "earth"){
        PlanetCollect.planet=2;
        audio.PlayOneShot(EarthCollect);
}

The static variable ("planet") belongs to the script that declared it ("PlanetCollect.js"). To access the variable in other scripts you have to refer to it as ParentScript.staticVariable (in this case, "PlanetCollect.planet").

You could further simplify this by using a builtin array to store your planet textures and audio clips:

var planetTexture : Texture2D[];

function Update () {
for (i=0;i<planetTexture.length;i++) {
    guiTexture.texture = planetTexture*;*
 *guiTexture.enabled = true;*
*}*
*}*
*```*
*<p>then in PlayerCollision:</p>*
*```*
*var planetAudio : AudioClip[];*
*function OnTriggerEnter(collisionInfo : Collider){*
*for (i=0;i<planetAudio.length;i++) {*
 *if(collisionInfo.gameObject.tag == i.ToString()){*
 *PlanetCollect.planet=i;*
 _audio.PlayOneShot(planetAudio*);*_
_*}*_
_*}*_
_*}*_
_*```*_
_*<p>To make this work you'd have to tag the planets as "0", "1", "2", etc.</p>*_
