How can I make the application remember what tracker was last tracked?
I need this for a kind of history menu where you should be able to get information about the last object.
What I'v tried so far is puting this code in ImageTargetBehaviour.cs:
public void update()
{
if (this.mStatus == Status.TRACKED)
{
if (gameObject.tag == "Object1")
{
PlayerPrefs.SetInt("LatestSeen", 1);
}
else if (gameObject.tag == "Object2")
{
PlayerPrefs.SetInt("LatestSeen", 2);
}
else if (gameObject.tag == "Object3")
{
PlayerPrefs.SetInt("LatestSeen", 3);
}
else if (gameObject.tag == "Object4")
{
PlayerPrefs.SetInt("LatestSeen", 4);
}
else if (gameObject.tag == "Object5")
{
PlayerPrefs.SetInt("LatestSeen", 5);
}
else if (gameObject.tag == "Object6")
{
PlayerPrefs.SetInt("LatestSeen", 6);
}
else if (gameObject.tag == "Object7")
{
PlayerPrefs.SetInt("LatestSeen", 7);
}
else if (gameObject.tag == "Object8")
{
PlayerPrefs.SetInt("LatestSeen", 8);
}
}
}
And then I try to grab these variables from my menu with this code in another c# script:
activeARObject = PlayerPrefs.GetInt("LatestSeen");
if(activeARObject == 1){
showHistory1 = true;
}else if(activeARObject == 2){
showHistory2 = true;
}else if(activeARObject == 3){
showHistory3 = true;
}else if(activeARObject == 4){
showHistory4 = true;
}else if(activeARObject == 5){
showHistory5 = true;
}else if(activeARObject == 6){
showHistory6 = true;
}else if(activeARObject == 7){
showHistory7 = true;
}else if(activeARObject == 8){
showHistory8 = true;
}
What is wrong with this code? :P
First off you probably want to use this method signature (capitalization matters):
public void Update() { }Second, you might be interested in the object's name, rather than its tag:
if (gameObject.name == "Object1") { }Finally, you may need to add a check for the DETECTED state as well, if you are tracking frame markers:
if (this.mStatus == Status.DETECTED || this.mStatus == Status.TRACKED) { }- Kim
