 |
|

I got the following code:
| Code: | var interaction;
function CloseEnough(interactTag : String, distToInteract : float) : boolean {
var allObjs : GameObject[] = GameObject.FindGameObjectsWithTag(interactTag);
for (var obj : GameObject in allObjs) {
var pos = obj.transform.position ;
var dist = Vector3.Distance(pos, transform.position);
if (dist <= distToInteract)
return true;
}
return false;
}
function Update() {
if(CloseEnough("People", 80.0)){
SendMessage ("Focus", true);
interaction=true;}
else
{SendMessage ("Focus", false);
interaction=false;}
// if(CloseEnough("Ladder", 0.1)) {
// code to interact with ladders
// }
}
function Focus (target1 : boolean) {
var people=GameObject.FindWithTag ("People");
if (target1==true)
people.light.enabled=true;
else
people.light.enabled=false;
} |
I want to have multiple instances, so if I closer to an object with the people tag, I can interact. The problem appears when I have to instances with the tag in the range of action, how can I find wich object is closer, so I can locked it and interact.

you would find out all objects that are of interest and then calculate the distance between them basing on their positions.
What you need to check in the script reference for the second part is Transform and Vector3

| In my code with some help I manage to get the distance of one object, with an specific tag, the problem appear when there are multiple objects close with the same tag. As you sujest I was thinking in an array, thus I it seams cannot reach that with my code. Could anyone ilustrate that, i was trying with raycasting, but I dont know how to first place distance and name in an array. I've seen some FPS tutorials for targeting and lock on, the problem is that my game is a third person, and I use the wiimote for the targeting.

Your CloseEnough function is already almost what you want. You just need to modify it to keep track of the closest element so far:-
| Code: | function CloseEnough(interactTag : String, distToInteract : float) : boolean {
var closest: float = 1000000.0;
var closestName: string = "";
var allObjs : GameObject[] = GameObject.FindGameObjectsWithTag(interactTag);
for (var obj : GameObject in allObjs) {
var pos = obj.transform.position ;
var dist = Vector3.Distance(pos, transform.position);
if (dist < closest) {
closest = dist;
closestName = obj.name;
}
}
if (dist <= distToInteract)
return closestName;
else
return "";
} |

I try to implement what andee saids, but I got some warnings, so I modify the code to something like this
| Code: |
var interaction;
var closestName:String;
function CloseEnough(interactTag : String, distToInteract : float) : boolean{
var allObjs : GameObject[] = GameObject.FindGameObjectsWithTag(interactTag);
for (var obj : GameObject in allObjs) {
var pos = obj.transform.position ;
var dist = Vector3.Distance(pos, transform.position);
if (dist<=distToInteract)
closestName = obj.name;
else
closestName=" ";
}
if (dist <= distToInteract)
return true;
else
return false;
}
function Update() {
print(closestName);
if(CloseEnough("People",50.0)){
interaction=true;}
else
{
interaction=false;}
// if(CloseEnough("Ladder", 0.1)) {
// code to interact with ladders
// }
} |
The problem is that if I got two objects with the People tag, I can only se the last object created name in the print, for example I got a capsule, and is the only object with the tag, so it works I got the print right. But if I create a Box with the same tag, I get close and the box name is print, but if I get close to the capsule, doesnt print anything.

I think you have to check for all objects around fixed distance and then filter what you need.
checkaround(distance){
return names
}
update(){
if checkaround(5.0=="people"){
for each obj in people{
which one has smallest distance
}
}
}
something like that

I can get this code to work properly, sinisa you are saying that my first function "closest" seams to be right, but I need to do a filtering, I tried to implement something like you suggest, but I cant make it worked.
What I tryed is to make another function, that do the filtering, like the checkaround that you suggest, then in my cycle first I compare distance with function CloseEnough and then Checkaround, but I only get null in the print of the name.
I know I have to first with my function CloseEnough check if the player in the range of interaction, if this is true I have to use CheckAroud, wich its a filter where I store [name,distance], and then compare within this array, but I cant make this algorythm, could someone help me?

| I've been trying to mod my code, but I couldn't make it work. Does anyone have another way to do it?. What I wanto to achieve is: When I press a key change to first person, in this view a target is created, but when an enemy is close and I press the same key I want to lock the target on the enemy. Something like LOZ, please help me Im really stuck in here

I see what I need but I cant implement it it seams that what I need is create a temporal distance and a temporal object reference, so if im close to an object, the function is activated, but if Im close to two reference find the closest of the two objects.
Here is the code I have:
| Code: |
static var interaction;
var others;
var other;
var cross:Transform;
function CloseEnough(interactTag : String, distToInteract : float) : boolean {
var allObjs : GameObject[] = GameObject.FindGameObjectsWithTag(interactTag);
var close;
var oldDist;
for (var obj : GameObject in allObjs) {
var pos = obj.transform.position ;
others = obj.transform.name;
other = obj.transform;
var dist = Vector3.Distance(pos, transform.position);
if (dist <distToInteract)
return true;
}
return false;
}
function Update() {
var joystick: Movementwii=GetComponent(Movementwii);
if(CloseEnough("People", 80.0)){
SendMessage ("Focus", true);
interaction=true;
if ( joystick.fromNunchuckZ==true){
cross.gameObject.active=true;
cross.position=other.transform.position+Vector3(0,20,0);
}
else
{
cross.gameObject.active=false;}
}
else
{SendMessage ("Focus", false);
interaction=false;
cross.gameObject.active=false;}
if(CloseEnough("Push", 80))
interaction=true;
else
interaction=false;
}
function Focus (target1 : boolean) {
if (target1==true){
other.light.enabled=true;
print("Close to:" + others);}
else
other.light.enabled=false;
} |
Could anyone tell me how can I do that?

The problem is that you are returning from the CloseEnough function as soon as you have found an object within the distance, but you need to check them all to find the closest:-
| Code: | var closest: GameObject;
var closestDist: float;
for (var obj : GameObject in allObjs) {
var pos = obj.transform.position;
var dist = Vector3.Distance(pos, transform.position);
if (dist < closestDist) {
closestDist = dist;
closest = obj;
}
}
if (closestDist < distToInteract) {
return obj;
} else {
return null;
}

I manage to solve all the errors, but seams not to do anything.It still doesnt work properly, when the distance is bigger than 100 there are problems, and it doesnt find the closest object
| Code: |
static var interaction;
var others;
var other;
var cross:Transform;
function CloseEnough(interactTag : String, distToInteract : float) : boolean {
var allObjs : GameObject[] = GameObject.FindGameObjectsWithTag(interactTag);
var close:GameObject;
var oldDist=0;
var temp:GameObject;
for (var obj : GameObject in allObjs) {
var pos = obj.transform.position ;
var dist = Vector3.Distance(pos, transform.position);
if(dist<oldDist||oldDist==0){
oldDist=dist;
close=obj;
}
if (oldDist <distToInteract&&close!=null) {
others = close.transform.name;
other = close.transform;
return true;
}
}
return false;
}
function Update() {
var joystick: Movementwii=GetComponent(Movementwii);
if(CloseEnough("People", 180.0)){
SendMessage ("Focus", true);
interaction=true;
if ( joystick.fromNunchuckZ==true){
cross.gameObject.active=true;
cross.position=other.transform.position+Vector3(0,20,0);
}
else
{
cross.gameObject.active=false;}
}
else
{SendMessage ("Focus", false);
interaction=false;
cross.gameObject.active=false;}
if(CloseEnough("Push", 80))
interaction=true;
else
interaction=false;
}
function Focus (target1 : boolean) {
if(other!=null){
if (target1==true){
other.light.enabled=true;
print("Close to:" + others);}
else
other.light.enabled=false;
}
}

As you can see in the image the player is closer to the capsule, but the target goes to the cube, thats the kind of problem I'm having with the script

Well I was trying to solve the problem, so I get to this code.
| Code: |
var attackRange = 200;
var target : GameObject;
function Start() {
var targets = gameObject.FindGameObjectsWithTag("TARGET");
print( "Targets found:" +targets.length );
}
function Update(){
var targets = gameObject.FindGameObjectsWithTag("People");
var mytarget : GameObject;
var maxdistance : int = 180; // dummy large distance
if (targets.length>0)
{
var curdist : float = attackRange;
for (var enemy : GameObject in targets)
{
//work out which item is the closest and shoot at it, or find out
//which enemy has the most armour left or the most power and shoot it.
print ("Checking enemy: "+enemy.transform.name);
var distance = Vector3.Distance(enemy.transform.position, transform.position);
if (distance < (curdist-2)) {
curdist = distance;
target = enemy;
}
if (target == enemy) {
print("My closest selected enemy so far is: "+target.transform.name);
}
}
if (target == null)
return;
}
}

I found this code in the forum, I adapted and I seams to work. But when I adapt my code to this one. I reach this:
| Code: |
static var interaction=false;
var cross:Transform;
var target : GameObject;
function CloseEnough(interactTag : String, distToInteract : float) : boolean {
var targets = gameObject.FindGameObjectsWithTag(interactTag);
var mytarget:GameObject;
if (targets.length>0){
var curdist : float = distToInteract;
for (var enemy : GameObject in targets) {
var distance = Vector3.Distance(enemy.transform.position, transform.position);
if(distance<curdist){
curdist=distance;
target=enemy;
return true;
}
if (target==null) {
return false;
}
}
}
}
function Update() {
var joystick: Movementwii=GetComponent(Movementwii);
if(CloseEnough("People", 120.0)){
SendMessage ("Focus", true);
if ( joystick.fromNunchuckZ==true){
cross.gameObject.active=true;
cross.position=target.transform.position+Vector3(0,20,0);
}
else
{
cross.gameObject.active=false;}
}
else
{SendMessage ("Focus", false);
cross.gameObject.active=false;}
}
function Focus (target1 : boolean) {
if(target!=null){
if (target1==true){
target.light.enabled=true;
interaction=true;}
else
{
target.light.enabled=false;
interaction=false;}
}
}
|
This code was working fine in the first two test, but the third test it stops working, as it should, an I reach the same point I was before. Please help me
