I am in the process of trying to add dynamic checkbox to my activity. However being a beginner i cant get round the basics of being able to add checkboxes and remove them. Here is my code....
private void createCheckbox() {
for(int i=0; i<5; i++){
cb = new CheckBox(this);
ll.addView(cb);
cb.setText("Test");
}
ll.addView(submit);
submit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
for(int i = 0; i < 5; i++) {
ll.removeView(cb);
}
ll.removeView(submit);
Questions();
}});
}
ll is a linerlayout object. The idea is when the code runs, 5 checkboxes appear and then once the user clicks on the submit button they get removed.
Currently the boxes are being seen, but when the submit button is pressed only one of the five is being removed. I don't understand what i am doing wrong?
For loop not ending correctly, curly bracket wrong place

i have a problem. iam making a game that have button for buy item , and the button have no issue, it run normally, but the problem is the button immediately executes the method without seeing that the method contains an if statement, so what is wrong here Here's the code :
public void TakeMoney()
{
int minusCoin = PlayerInfo.coin -= 5;
PlayerPrefs.SetInt("MyCoinAmount", minusCoin);
}
public void DisableBuyButton()
{
disableBuyButtonRocket3 = 1;
PlayerPrefs.SetInt("DisableBuyButtonRocket3", disableBuyButtonRocket3);
}
public void Buy()
{
int getPlayerCoin = PlayerInfo.coin;
if (getPlayerCoin > 4)
{
if (MyRocket._rocket3 == 1)
{
GetComponent<AudioSource>().Play();
MyRocket._rocket3 = 1;
PlayerPrefs.SetInt("Rocket3Bought", MyRocket._rocket3);
}
}
}
so the button will perform all of the 3 functions above, but as can be seen that I make an if statement so the item can only be purchased if we already have enough money, but when I try I try to reset all values, so my money by default it is 0, but I can buy the item and my money becomes a minus.
Btw, PlayerInfo above is a script from another scene.
Sorry for my bad english.
Your problem is that you do everything in separated methods. It's basically not a problem - but, when you execute them concurrently, it is. Also, your methods are completely independent of each other - an if statement in one will not affect the others' execution. The solution is that you first remove the event listeners to TakeMoney and DisableBuyButton. Then, call them from Buy. If you think it through, it is more logical. Also, remove the temporary variables, as they slow down your code a bit and also make it less readable. Final code could be something like this:
public void TakeMoney()
{
PlayerInfo.coin -= 5;
PlayerPrefs.SetInt("MyCoinAmount", PlayerInfo.coin);
}
public void DisableBuyButton()
{
PlayerPrefs.SetInt("DisableBuyButtonRocket3", 1);
}
public void Buy()
{
if (PlayerInfo.coin > 4) {
TakeMoney();
DisableBuyButton();
if (MyRocket._rocket3 != 1 /* changed this, because it seemed that you want to check whether it is NOT one */)
{
GetComponent<AudioSource>().Play();
// I changed the if statement because this
MyRocket._rocket3 = 1;
PlayerPrefs.SetInt("Rocket3Bought", MyRocket._rocket3);
}
}
}
the playerinfo.coin value would be more than 4 because it will decrease coin at click so it will minus only 5 at a click you could check playerinfo.coin value
I am creating a 3d image gallery with virtual buttons. Presently using the virtual button example from vuforia site, I am able to implement each button for a single image.
I want to create only two buttons to navigate with virtual button. How Can i go with this.
The Below code is not tested, but should be simple to drop in to a C# script and the editor will point out what warnings you might get and suggest an easy fix.
List<Texture> MyImageList = new List<Texture>();
int imageIndex = 0;
void OnGUI() {
GUI.DrawTexture(new Rect(0,0,Screen.width, Screen.height), MyImageList[imageIndex]);
if(GUI.Button(new Rect(10,10,80,10), "Prev")) {
Prev();
}
if(GUI.Button(new Rect(200,10,80,10), "Next")) {
Next();
}
}
void Next() {
if(imageIndex < MyImageList.Count)
imageIndex++; else imageIndex = 0;
}
void Prev() {
if(imageIndex > MyImageList.Count)
imageIndex--; else imageIndex = MyImageList.Count;
}
its not a virtual button as such, but using a global list indexer is the best option, as the above demonstrates .
Im beggineer in programming and i'm trying to delete the master slide usign the c# but it always throws an exception "Specified cast is not valid" Is there any way to delete the master slide or shapes on the master slide .. please suggest.
for (int i = 1; i <= SlideCount; i++)
{
int j=i;
slide = Slides[i];
//iterate over all the shapes of notespage of given slide to find the notespage's shape which has text.
for (int k = 1; k <= slide.NotesPage.Shapes.Count; k++)
{
var noteShape = slide.NotesPage.Shapes[k];
//check if the selected notespage has text or not
if (noteShape.Type ==MsoShapeType.msoPlaceholder)
{
if (noteShape.PlaceholderFormat.Type ==PpPlaceholderType.ppPlaceholderBody)
{
if (noteShape.HasTextFrame ==MsoTriState.msoTrue)
{
if (noteShape.TextFrame2.HasText ==MsoTriState.msoTrue)
{
//create a new slide
newslide = tempslides.AddSlide(++j, customLayout);
// set the title of newslide as the text of notepage of previous slide.
newslide.Shapes.Title.TextFrame.TextRange.Text = noteShape.TextFrame.TextRange.Text;
//delete the notepage text;
noteShape.TextFrame.TextRange.Delete();
//delete footer from slide.
//if (newslide.HeadersFooters.Footer.Visible == MsoTriState.msoTrue)
// newslide.HeadersFooters.Footer.Text = string.Empty;
//newslide.HeadersFooters.DateAndTime.Text = string.Empty;
//newslide.HeadersFooters.SlideNumber.Text = string.Empty;
newslide.HeadersFooters.Clear();
newslide.Master.Delete();
//jump to next slide
i++;
//increase the slide count becoz one slide has been added.
SlideCount = tempslides.Count;
}
}
}
}
}
}
You can't delete a master or layout that any slides are based on. Why do you want to delete the master slide?
To delete the shapes:
newslide.Master.Shapes.Range.Delete
That will delete the shapes from the slide master, but not the layout that the slide is based on, so it may not be exactly what you need.
Flash AS3:
I just need to know how to check a condition for roll over effect on similar colour movieclips which is near by in a group of random colours movieclips in a grid whereas it is using 2D Array in flash AS3.or
I just need roll over event which i wrote is onBoxOver event function, in that the object which i am targetting is only getting rollover or getting alpha changes. But i need to know how to make rollover for similar colour which are all nearby.
The code which i wrote is below for your reference.

![My Game screenshot here colourbox][1]
Thanks in Advance. Greatly Appreciable for the reply.
Hi this is the image or screenshot of my project. In that image there are 8 colours randomly arranged. whenever i make mouse position or rollover on any box , the condition should check whether the same colour occurs around the box(eg.top, down, left, right) which i am making rollover.
1.If the same colour occur on the top of the box which i am pointing the cursor , the top box and the box which i am pointing both should get less alpha, else only the pointing box should get less alpha. this is my concept friends. please go through the image and let me know if u have any doubts.
I am still unsure what you mean by 'nearby'. (neighbour tiles? adjacent of similar colour?...)
If 'nearby' means adjacent, you need to read about flood fill algorithms. There is a good wiki article about this. You would use that to crawl through the list of tiles similar enough to trigger the effect you want.
I also don't know what 'similar' colour means in your project. You will need a method to determine weather two colours are similar. There is a stackoverflow question re: similar colour detection. It has a good answer to start you out in your research. look here.
I'm a beginner of ActionScript 3.0. I'm making a simple memory game, the tool I'm using is Eclipse with flexsdk plugin. Right now I've done the shuffle and display images, and the cover of the images as well.
My idea is when clicking on the image, the cover will remove and show the image behind of it. After 2 covers are gone, the game will compare and check whether the selected images are match or not, if match both of the images will remain, otherwise the cover will reappear and the game keeps going on. If all of the images are match, a winning line will appear.
The problem I'm facing is I got no idea on how to deal with the images comparison part. I wanted to compare with the index number of array or the name of the images, but I really don't have any idea. I've refer some examples but all of them are develop in CS3 and uses the timeframe which is not exist in pure ActionScript.

Please help me figure out. Thanks.
Well I didn't really go through your code in details, but from looking at it, it seems you are making things really complex. So let me give you a hint in how I would do it...
1) First I would make a 'card' class, which extends sprite or bitmap, mainly containing the image of that card, image of the cover/mask, some animtion methods like hide/show e.t.c, and possibly an 'id' variable to recognize it later, though that is not needed. You can also get away with the array you have, and in that case, skip step 2.
2) Now push two copies of each card in an array.
example [new card('c1'),new card('c1'),new card('c2'),new card('c2'),.....].
3) Now comes the part where you made it most complex, that is, the shuffling of the array. Let's write a custom function for it, shall we?
function shuffleArr(arr):Array
{
var len:int = arr.length();
for(var i:int=0; i<len; i++)
{
//Swap the value at i with a random value within the array;
var tmp_pos:int = Math.floor(Math.random()*len);
while(tmp_pos==i)
{
tmp_pos = Math.floor(Math.random()*len);
}
var tmp_var:card = arr[tmp_pos];
arr[tmp_pos] = arr[i];
arr[i] = tmp_var;
}
}
4) Now that the array is shuffled, you simply have to lay them out in a grid.
for(var row:int=0; row<6; row++)
{
for(var col:int=0; col<6; col++)
{
card_arr[i].x = card_arr[i].width*cols+5;
card_arr[i].y = card_arr[i].height*row+5;
stage.addChild(card[i]);
}
}
5) Now you have to check for user click and take action, and there are many ways to do it, but I will tell one of them...
a) Give the cards a click event handler, this becomes easy if the cards are a class, or you can look into event.target property and use a general click handler. it's up to you.
b) On click, push the card's id in an array. If you did make them into a class, their ids should now be, c1, c2, e.t.c, and you can do
holder_arr.push(this);
this.removeCover();
6) Now you have to make sure, that the holder array can only hold two values at a time. Then do the checking. I am writing a semi-pseudo code with a lot of assumed functions and values:
//Insert
if(holder_arr.length()==2)
{
//flip back the cards and empty the array
holder_arr[0].showCover();
holder_arr[1].showCover();
holder_arr = [];
}
holder_arr.push(this);
...
..
7) For checking make a function and run it every time a card is clicked, and also when a timer ends, to flip back the cards.
function checkCards()
{
if(holder_arr.length==2)
{
if(holder_arr[0].id==holder_arr[1].id)
{
//the cards match
holder_arr[0].vanishAnim();
holder_arr[1].vanishAnim();
holder_arr=[];
}
else
{
holder_arr[0].showCover();
holder_arr[1].showCover();
holder_arr=[];
}
}
}
Obviously you will remove the cards from the actual card_arr too, but when to do that is up to you to figure out ;)
Personally , I find the problem has more to do with the way you shuffle your cards as it makes it a bit more difficult to identify what card is what.
Let's say for instance that instead of shuffling your embed assets , you were first creating your cards , naming them after the image they add , then creating an Array ( or Vector ) of cards and shuffle that Array ( or Vector ), identifying the cards would be fairly easy since you'd only have to compare their name property.
//PSEUDO CODE
- create Array ( Vector ) of embed assets [PIC1, PIC2 , PIC3]
- create cards and use Array ( Vector ) index to identify
each card with the name property
- create a set of six cards
- shuffle set
