So, I have a list of Upgrade systems for my game but it has a bug on it when I press upgrade for a second time the index out of range then pressed for the third times the index out of range gone. this whole script.
void Start()
{
newSelectedIndex = previousSelectedIndex = PlayerPrefs.GetInt("currentPlayer");
btn = Select_Player[newSelectedIndex].GetComponent<Button>();
btn.interactable = false;
Coins = M_CoinManager.instance.Coins;

{
priceText[i].text = Cost_Player[i].ToString();
value_player[i] = "" + i;
Select_Player[i].SetActive(false);
buyPlayer[i] = PlayerPrefs.GetInt(value_player[i]);
}
//if(PlayerPrefs.HasKey("currentPlayer")){
selectedVehicleIndex = PlayerPrefs.GetInt("currentPlayer");
theVehicles[selectedVehicleIndex].SetActive(true);
VehicleInfo();
UpgradeButtonStatus();
}
// Update is called once per frame
void Update()
{
for (int i = 0; i < Select_Player.Length; i++)
{
buyPlayer[i] = PlayerPrefs.GetInt(value_player[i]);
if (i == buyPlayer[i])

}
}
and the error reference to this method :
private void UpgradeButtonStatus()
{

{
upgradeBtn[selectedVehicleIndex].interactable = true;

}
else
{
upgradeBtn[selectedVehicleIndex].interactable = false;
upgradeBtnText[selectedVehicleIndex].text = "Max Level";
}
}
as you can see on the update that's what I mean. after i press upgrade for third times the error stopped.
and this for the inpector
Arrays length is one higher than their highest index, but last iteration of "for" loops goes to array.length.
You need to make "for" loops to array.length-1.
I see you do "for" loops of up to array.length.
I haven't truly read thru your whole script so there might be more, but it's a typical error in my "for" loops so I think that is causing your error.
I am using slideUI controls in my project . There is a spinner control which is used as wait cursor. I want to display the spinner when I load data in a List.
But when I try to display the spinner it visualize as an image not a rotating image.
Below is my code.
private void uiButton_Click(object sender, EventArgs e)
{
ShowFrame(this.uiPanel1);
Application.DoEvents();
LoadList();
HideFrame(uiPanel1);
}

try
{
//Call the BeginAddControls before starting manipulations with UIList
uiList1.BeginAddControls();
for (int i = 0; i < 100; i++)
{
UIListItem item = new UIListItem();
item.Text = "Primary Text" + i;
item.SecondaryText = "This is secondary text..";
item.ItemStyle = UIListItemStyle.SingleText;

I'm having an issue with my hangman program. When I run it, the label holding the int variable "lives" is supposed to update when you guess a wrong letter. But for some reason it isn't. I've placed this in my code as a test mechanism, and it isn't appearing even here.
if (used[letter] = false) {
System.out.println("test");
However, when I place it here.. It DOES work..
if (finished == false) {
boolean found = false;
boolean www = false;
System.out.println("test");
if (used[letter] = false) {
It almost leads me to believe that used[letter] is true by default, when it really shouldn't be. The variable is declared at the very top. Any thoughts?

Make that:

You just set used[letter] to false. Try ==
Of course, to avoid this typo you shouldn't be using == but rather ...

Ok. so I'm writing a grocery checkout system code and on the right side of the frame, I'm displaying a Jpanel with Labels. Every time I click the 'Scan' button, I add a new label into the JPanel so that everytime I click, it displays the output. However, I can only fit so many entries in my window, how do I incorporate a scroll bar so that I can scroll through the groceries?
I tried inputting a scroll bar EAST with a BorderLayout and all the labels CENTER, however, everytime I click the button, it only reprints it at the same exact spot instead of top/down so that I can scroll. (Please, bare in mind that this is a very very rough draft. I'll be incorporating the logic beneath the code once I get the nitty-gritty with the GUI)
Here's my code:

private StringBuffer[] itemDesc = new StringBuffer[numOfItems];
private Double[] unitPrice = new Double[numOfItems];

I have a question about collapse panel..
I have a placeholder and I add more than one headerpanel, contentpanel, collapsiblepanel dynamically.. Here is my code :
CollapsiblePanelExtender cpe = new CollapsiblePanelExtender();
Panel pnlheader,pnlcontent;
Label lblcontent,lblheader; Button btn;
for (int i = 0; i < 10; i++)
{
///// PANEL HEADER VE ICERIGI //////////
pnlheader = new Panel();
pnlheader.ID = "PanelHeader" + i;
pnlheader.BackColor = System.Drawing.Color.Blue;
lblheader = new Label();
lblheader.ID = "LabelHeader" + i.ToString();
lblheader.Text = (i + 1) + ". Header";
pnlheader.Controls.Add(lblheader);
/////////PANEL CONTENT VE ICERIGI //////////
pnlcontent = new Panel();
pnlcontent.ID = "PanelContent" + i;
pnlcontent.BackColor = System.Drawing.Color.DarkRed;
lblcontent = new Label();
lblcontent.ID = "LabelContent" + i.ToString();
lblcontent.Text = "<table><tr><td border=\"1\">DENEMEE</td></tr></table>";
btn = new Button();
btn.ID = "Button" + i.ToString();
btn.Text = "Deneme.Button";
pnlcontent.Controls.Add(lblcontent);
pnlcontent.Controls.Add(btn);
///////// COLLAPSEPANEL ICERIGI///////
cpe = new CollapsiblePanelExtender();
cpe.ID = "CollapsePanel" + i;
cpe.TargetControlID = "PanelContent" + i;
cpe.ExpandControlID = "PanelHeader" + i;
cpe.CollapseControlID = "PanelHeader" + i;
PlaceHolder2.Controls.Add(pnlheader);
PlaceHolder2.Controls.Add(pnlcontent);
PlaceHolder2.Controls.Add(cpe);
}
How can I understand which panel expanded..
it is very important, please help..
Firstly you should to find all controls of CollapsiblePanelExtender type inside the scope of PlaceHolder2.
Then you'll be able to get Collapsed property of each found CollapsiblePanelExtender instance.
