I am making a game where there there are frogs hopping around the screen. Once a frog is touched, I change the game image to what I have set as "deadFrog" and its movement stops. I have them all created under and array-list, and I am unsure as to how to only make changes to the individual frog. Right now, if one frog is tapped, all of the frogs stop moving and change to deadFrog. Hopefully you can help me fix the tactical nuke of a tap ;) *If you need any more information, just comment and I'll be sure to provide it!
Edit Is there not a way to access a single element in the blocks arraylist? I've tried doing blocks(1) for example but that's invalid.
Here is where the frogs are declared:
public void init() {
blocks = new ArrayList<Block>();
for (int i = 0; i < 5; i++) {
Block b = new Block(i * 200, MainActivity.GAME_HEIGHT - 95,
BLOCK_WIDTH, BLOCK_HEIGHT);
blocks.add(b);
tapped = false;
}
}
They are rendered with this:
private void renderFrogs(Painter g) {
if (!tapped) {
for (int i = 0; i < blocks.size(); i++) {
Block b = blocks.get(i);
if (b.isVisible()) {
Assets.runAnim.render(g, (int) b.getX(), (int) b.getY());
}
}
}
if (tapped) {
for (int i = 0; i < blocks.size(); i++) {
Block b = blocks.get(i);
if (b.isVisible()) {
g.drawImage(Assets.deadfrog, (int) b.getX(), (int) b.getY());
}
}
}
}
And this is the onTouchListener:
public boolean onTouch(MotionEvent e, int scaledX, int scaledY) {
if (e.getAction() == MotionEvent.ACTION_DOWN) {
recentTouchY = scaledY;
} else if (e.getAction() == MotionEvent.ACTION_UP) {
for (int i = 0; i < blocks.size(); i++) {
Block b = blocks.get(i);
if ((scaledY >= b.getY() - BLOCK_HEIGHT || scaledY <= b.getY()) && (scaledX >= b.getX() || scaledX <= b.getX() + BLOCK_WIDTH)) {
tapped = true;
}
}
}
return true;
}
Of course all frogs turn dead, you are supposed to keep "tapped" variable for each frog, your tapped variable is for all frogs at once.
Declare a class
public class Frog extends View{
public Drawable liveFrog;
public Drawable deadFrog;
public boolean isDead;
public Point location;
public int width;
public int height;
public Frog(Context context, int x, int y,int width,int height){
super(context);
this.isDead = false;
this.location = new Point(x,y);
this.width = width;
this.height = height;
}
public void onDraw(Canvas c){
super.onDraw(c);
if(!isDead){
//draw live frog at x,y
}else {
//draw dead frog at x,y
}
}
}
then you array is supposed to contain frogs
public void init(Context context) {
blocks = new ArrayList<Frog>();
for (int i = 0; i < 5; i++) {
Frog b = new Frog(context,i * 200, MainActivity.GAME_HEIGHT - 95,
BLOCK_WIDTH, BLOCK_HEIGHT);
blocks.add(b);
}
}
private void renderFrogs() {
for(Frog f : blocks){
//cause redraw
f.invalidate();
}
}
here comes the fun part, when you tap the frog
public boolean onTouch(MotionEvent e, int scaledX, int scaledY) {
if (e.getAction() == MotionEvent.ACTION_DOWN) {
recentTouchY = scaledY;
} else if (e.getAction() == MotionEvent.ACTION_UP) {
for (int i = 0; i < blocks.size(); i++) {
Frog frog = blocks.get(i);
if ((scaledY >= frog.getY() - BLOCK_HEIGHT || scaledY <= frog.getY()) && (scaledX >= frog.getX() || scaledX <= frog.getX() + BLOCK_WIDTH)) {
frog.isDead = true;
//cause one frog redraw
frog.invalidate();
//if the event was handled, stop here (unless you can have multiple frogs one on top of the other ?
return true;
}
}
}
//if the event was not handled, let it bubble up
return false;
}
From what I can see, your "tapped" boolean is not a property of EACH frog. It is declared once, and when triggered, per your for loop, will make every frog dead (obviously, since that's what you're experiencing).
Once "tapped" is true, your for loop is going through every block and assigning a dead frog to it.
I think you need to create a Frog class, and store instances of those in your ArrayList. A variable of the new frog class will be "touched", and when that is triggered you will do something to that specific instance only.
In my app, I want to switch a bitmap image from one to another when I touch on that image. I keep getting NULLPOINTEREXCEPTION whenever I touch the image.
Is there any method that allows to switch from a bitmap to other bitmap?
#Override

canvas.drawColor(Color.BLACK);
this.cVas = canvas;
for(int i = 0; i < BSIZE; i++) {

gameBoard[i][j] = new Cell(i*wCell, j*wCell+hCell);
if(gameBoard[i][j].getBitmap() == null) {
gameBoard[i][j].setBitmap(b3);
}
/*if(gameBoard[i][j].getTouch()) {
gameBoard[i][j].setBitmap(b4);
}else{
gameBoard[i][j].setBitmap(b3);
}*/
gameBoard[i][j].drawCell(canvas);
}
}
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if(event.getAction() != MotionEvent.ACTION_DOWN) {
return super.onTouchEvent(event);
}
// Get the Cell's position.
selX = (int)((event.getX()) / wCell);
selY = (int)((event.getY() - hCell) / wCell);
if( selX > BSIZE || selY > BSIZE || selY < 0) {
return false;
}
else {
Log.d(TAG, "selX: " + selX + " selY: " + selY);
cellSelection(selX, selY);
}
return true;
}
// Redraw the image (switch to other bitmap).
private void cellSelection( int x, int y) {
if(gameBoard[x][y].getTouch()) {
gameBoard[x][y].setTouch(false);
gameBoard[x][y].setBitmap(b3);
} else {
gameBoard[x][y].setTouch(true);
gameBoard[x][y].setBitmap(b4);
}
gameBoard[x][y].drawCell(cVas);

Try this (instead of the setContentView )

I have a custom view, and within the custom view I create 4 text views. I want each of these text views to respond to on touch events. However, the textviews themselves do not respond to an on touch event. I can however, make an ontouch listener for the entire custom view. However, I do not want the whole view to have an ontouch event because I want the textviews that I have created to be dragged and dropped. I tried going the route of registering the x and y coordinates of the ontouch event and assuming that if the ontouch event is within the bounds of a textview, to change the coordinates of the textview, but that was overly complicated because if one textview got dragged to the coordinates of another one, then the ontouch event would "pick up" the other textview, so then I'd be moving two text views, which is not what I want. So, to sum it up, I want to know if it's possible to set in ontouch listener for a textview inside a customview, and if possible, why it is not working:
mScale.mPositive.get(0).setOnTouchListener(new OnTouchListener()
{
#Override
public boolean onTouch(View v, MotionEvent event)
{
mScale.mCurrentXPos[0] = event.getX();
mScale.mCurrentYPos[0] = event.getY();
mScale.mDrag = true;
return true;
}
});

Here is the custom view code:

The reason your TextView cannot receive touch events is that the TextView is drawn on the canvas just as a bitmap, not as a View. An excerpt from your code shown below illustrates this.
protected void onDraw(Canvas canvs)
{
....
negative = new TextView(mContext);
...
canvas.drawBitmap(negative.getDrawingCache(), ...)
To deliver touch events to your TextView, your Scale class should extend not View but ViewGroup and the TextView needs to be added as a subview to Scale class by using ViewGroup.addView() or addViewInLayout(). It is not a simple task to implement a ViewGroup subclass. You may have to implement onInterceptTouchEvent(MotionEvent) depending on your needs.
Android's source code will be of help.
Is your CustomView also sets some TouchListner??
If yes then this might causing issue..Remove TouchListner from CustomView and see if it works..
I am creating a game which uses andendgine and here is my code:
Player stanley = new Player();
...
scene.registerUpdateHandler(new IUpdateHandler() {
public void onUpdate(float pSecondsElapsed) {
stanX = stanley.getX();
destX = x.getX();
if(destX < stanX){
if(hasMovedRight == 1){
stanley.stop();
hasMovedRight = 0;
}
else{
stanley.moveLeft();
hasMovedRight = 0
hasMovedLeft = 1;
}
}
if(destX > stanX){
if(hasMovedLeft == 1){
stanley.stop();
hasMovedLeft == 0;
}
else{
stanley.moveRight();
hasMovedLeft = 0;
hasMovedRight = 1;
}
}
}
}
what i want is to stop Player from walking whenever his position X is equal to the touched area X. The problem is it never stop from walking. Thanks!
Your if statements are missing an element where destX == stanX. and you should really use else if. See modified code below.
if(destX + 8 < stanX){
if(hasMovedRight == 1){
stanley.stop();
hasMovedRight = 0;
}
else{
stanley.moveLeft();
hasMovedRight = 0
hasMovedLeft = 1;
}
}
else if(destX - 8 > stanX){
if(hasMovedLeft == 1){
stanley.stop();
hasMovedLeft == 0;
}
else{
stanley.moveRight();
hasMovedLeft = 0;
hasMovedRight = 1;
}
}
else //makes stanley stop. (calls stop method), if at touched x.
{
stanley.stop();
hasMovedRight = 0;
hasMovedLeft = 0;
}
try this one
setOnSceneTouchListener(new IOnSceneTouchListener() {
#Override
public boolean onSceneTouchEvent(Scene scene, TouchEvent event) {
int touchX = (int) (event.getX() - (sCHARStanley.getWidth() / 2));
//so that your sprite will go to the touched part of the screen
}
