This program is about driving fast and dodging the obstacles. I followed a couple of tutorials and managed to create an explosion class. Whenever a collision occurs, the explosion is meant to appear, but it doesn't.
There is no error, but I think the problem is in the Game1.cs. I created the following functions in the Game1.cs:
//list
List <Explosion> explosionList = new List<Explosion>();
//This is in the update method
foreach (Explosion ex in explosionList)
{
ex.Update(gameTime);
}
//This is a method called manage explosions
public void ManageExplosions()
{
for (int i = 0; i < explosionList.Count; i++)
{
if (explosionList[i].isVisible)
{
explosionList.RemoveAt(i);
i--;
}
}
}
//This is placed in the CheckCollision method
explosionList.Add(new Explosion(Content.Load<Texture2D>("Images/explosion3"), new Vector2(theHazard.Position.X, theHazard.Position.Y)));

First of all you need to draw your Explosions after road, car, hazards etc. Replace next code as shown below:
DrawRoad();
DrawHazards();
spriteBatch.Draw(mCar, mCarPosition, new Rectangle(0, 0, mCar.Width, mCar.Height), Color.White, 0, new Vector2(0, 0), 0.2f, SpriteEffects.None, 0);
// place code here
foreach (Explosion ex in explosionList)
{
ex.Draw(spriteBatch);
}
//
Into manage explosion method make !isVisible instead of isVisible:
public void ManageExplosions()
{
for (int i = 0; i < explosionList.Count; i++)
{
if (!explosionList[i].isVisible)
{
explosionList.RemoveAt(i);
i--;
}
}
}
Remove line:
foreach (Hazard aHazard in mHazards)
{
if (CheckCollision(aHazard) == true)
{
//remove next line because it is duplicate of adding Explosion which is already added inside CheckCollision(Hazard) method
//explosionList.Add(new Explosion(Content.Load<Texture2D>("Images/explosion3"), new Vector2(aHazard.Position.X, aHazard.Position.Y)));
break;
}
MoveHazard(aHazard);
}
Change next variables:
spriteWidth = 71;//128;
spriteHeight = 100;//128;
sourceRect = new Rectangle(currentFrame * spriteWidth, 0, spriteWidth, spriteHeight);
//origin = new Vector2(sourceRect.Width / 2, sourceRect.Height / 2);
origin = new Vector2(-(sourceRect.Width / 4), 0);
Comment next code for testing:
if (mCurrentState == State.Crash)
{
//DrawTextDisplayArea();
//DrawTextCentered("Crash!", 200);
//DrawTextCentered("Press 'Space' to continue driving.", 260);
}
I'm trying to draw a line from the player to a targets asteroid as a "Grapple" hook, i've found some examples for doing this in 2D in xna but my "Position" and "origin" vector2 seems to change depending on who and when they are used. In the case of the lines they appear to draw up and right of the position (roughly 100 pixels) in the opposite direction of the target and rotate about an origin somewhere to the left of the target as the player moves.
here is the player code including the grapple code and target assignment

What do you mean by "shooting" ?
So you have your tuioClient and you initialize it in setup(). Thats good, because then the callback methods (addTuioObject, removeTuioObject, updateTuioObject, addTuioCursor, updateTuioCursor, removeTuioCursor, refresh) will fire whenever your sketch receives a TUIO message.
Keep in mind that TUIO is based on OSC which is transported over UDP. That means the tracker (reactivision & co) will have to send to the IP and port your sketch is listening to. If both are on the same machine use 127.0.0.1 and port 3333 (default).
Have a look at the examples. You'll find them in the processing "IDE" click:
"File -> Examples"
and Navigate to
"Contributed Libraries -> TUIO"
I want to make an Analog Clock In blackberry, and I want the hands of the clock to be custom images.
I gone through this thread Help with analog clock code but didnt get it worked. Can any body help me to make an analog clock
Update
The code i am getting is from the supports forum
// How to use it
ClockBitmapField clock = new ClockBitmapField(face, Field.NON_FOCUSABLE | Field.FIELD_HCENTER,
hrPng, minPng, secPng);
I can i use this to make an analog clock
How Can i use this
add(clock);

and make minutes as second
thanks and regards
Just by looking at the code, it appears that the inputs:
String [] hourPngs, String [] minPngs, String [] secPngs are each a list of filenames of images which represent the clock hands at each position.
In this snippet, he builds an array of 60 Bitmaps from the strings:
_secBitmaps = new Bitmap [secPngs.length];
for ( int i = 0; i < secPngs.length; i++ ) {
_secBitmaps[i] = Bitmap.getBitmapResource(secPngs[i]);
}
Then, in this snippet you can see he gets the Bitmap object from a array by passing in the current "second" as the index:
_g.drawBitmap(0, 0, _faceWidth, _faceHeight, _secBitmaps[_curSec], 0, 0);
There doesn't appear to be any code where he rotates the images or anything.
So I guess that means you need 60 images for each clock hand. (180 images in total, plus the clock face).
I can able to show one location using co ordinates or longtitude and latitude but i dont know how to show more than one location in the blackberry MapField.If is it possible pls share with me how to do this..
Same way as How to show our own icon in BlackBerry Map?.
Pass an array of Coordinates into custom MapField, define a bitmap for location point and paint it for each Coordinate in custom MapField paint() method.
Remember to zoom in/out CustomMapField for best fit of all location points.
Sample of implementation
Lets display Liverpool Sheffield and London with custom bitmap icons (yellow circle with black border). Code for custom MapField:
class MultyMapField extends MapField {
Coordinates[] mPoints = new Coordinates[0];
Bitmap mPoint;
Bitmap mPointsBitmap;
XYRect mDest;
XYRect[] mPointDest;
public void addCoordinates(Coordinates coordinates) {
Arrays.add(mPoints, coordinates);
zoomToFitPoints();
repaintPoints();
}
protected void zoomToFitPoints() {
// zoom to max
setZoom(getMaxZoom());
// get pixels of all points
int minLeft = getWidth();
int minUp = getHeight();
int maxRight = 0;
int maxDown = 0;
Coordinates minLeftCoordinates = null;
Coordinates minUpCoordinates = null;
Coordinates maxRightCoordinates = null;
Coordinates maxDownCoordinates = null;
for (int i = 0; i < mPoints.length; i++) {
XYPoint point = new XYPoint();
convertWorldToField(mPoints[i], point);
if (point.x <= minLeft) {
minLeft = point.x;
minLeftCoordinates = mPoints[i];
}
if (point.x >= maxRight) {
maxRight = point.x;
maxRightCoordinates = mPoints[i];
}
if (point.y <= minUp) {
minUp = point.y;
minUpCoordinates = mPoints[i];
}
if (point.y >= maxDown) {
maxDown = point.y;
maxDownCoordinates = mPoints[i];
}
}
double moveToLat = maxDownCoordinates.getLatitude()
+ (minUpCoordinates.getLatitude() - maxDownCoordinates
.getLatitude()) / 2;
double moveToLong = minLeftCoordinates.getLongitude()
+ (maxRightCoordinates.getLongitude() - minLeftCoordinates
.getLongitude()) / 2;
Coordinates moveTo = new Coordinates(moveToLat, moveToLong, 0);
moveTo(moveTo);
// zoom to min left up, max right down pixels + 1
int zoom = getZoom();
boolean outOfBounds = false;
while (!outOfBounds && zoom > getMinZoom()) {
zoom--;
setZoom(zoom);
XYPoint point = new XYPoint();
try {
convertWorldToField(minLeftCoordinates, point);
if (point.x < 0)
outOfBounds = true;
convertWorldToField(minUpCoordinates, point);
if (point.y < 0)
outOfBounds = true;
convertWorldToField(maxRightCoordinates, point);
if (point.x > getWidth())
outOfBounds = true;
convertWorldToField(maxDownCoordinates, point);
if (point.y > getHeight())
outOfBounds = true;
} catch (IllegalArgumentException ex) {
outOfBounds = true;
}
}
zoom++;
setZoom(zoom);
}
protected void repaintPoints() {
mPointsBitmap = new Bitmap(getWidth(), getHeight());
mPointsBitmap.createAlpha(Bitmap.ALPHA_BITDEPTH_8BPP);
mDest = new XYRect(0, 0, mPointsBitmap.getWidth(), mPointsBitmap
.getHeight());
Graphics g = new Graphics(mPointsBitmap);
if (null != mPoint) {
mPointDest = new XYRect[mPoints.length];
for (int i = 0; i < mPoints.length; i++) {
if (null == mPointDest[i]) {
XYPoint fieldOut = new XYPoint();
convertWorldToField(mPoints[i], fieldOut);
int imgW = mPoint.getWidth();
int imgH = mPoint.getHeight();
mPointDest[i] = new XYRect(fieldOut.x - imgW / 2,
fieldOut.y - imgH, imgW, imgH);
}
g.drawBitmap(mPointDest[i], mPoint, 0, 0);
}
}
}
protected void paint(Graphics graphics) {
super.paint(graphics);
if (null != mPointsBitmap) {
graphics.setGlobalAlpha(100);
graphics.drawBitmap(mDest, mPointsBitmap, 0, 0);

}
Sample of use:
class Scr extends MainScreen {
// test coordinates:
// London
// 51.507778, -0.128056

// Sheffield
// 53.385833, -1.469444
Coordinates mSheffieldC = new Coordinates(53.385833, -1.469444, 0);
MultyMapField mMultyMapField;
public Scr() {
add(mMultyMapField = new MultyMapField());
mMultyMapField.mPoint = createPointBitmap();
}
protected void onUiEngineAttached(boolean attached) {
super.onUiEngineAttached(attached);
if (attached) {
mMultyMapField.addCoordinates(mLondonC);
mMultyMapField.addCoordinates(mLiverpoolC);
mMultyMapField.addCoordinates(mSheffieldC);
}
}
private Bitmap createPointBitmap() {
int r = 10;
Bitmap result = new Bitmap(2 * r, 2 * r);
result.createAlpha(Bitmap.ALPHA_BITDEPTH_8BPP);
Graphics g = new Graphics(result);
g.setColor(Color.BLACK);
g.fillEllipse(r, r, 2 * r, r, r, 2 * r, 0, 360);
g.setColor(Color.YELLOW);
g.fillEllipse(r, r, r + (r - 2), r, r, r + (r - 2), 0, 360);
return result;
}
}
A valid and probably simpler option would be to use this open source library by Monits https://github.com/Monits/blackberry-commons
It contains several common functionality found in BB applications and is compatible for BB 4.6.1+
Among other things, it provides a map field with the ability to add and display markers on top of it, with and without focus, and optionally "open" them. This makes for an API much more alike that found on other smart phones such as iPhone or Android.
The documentation is pretty good, and the wiki even has a tutorial on how to achieve it https://github.com/Monits/blackberry-commons/wiki/CustomMap
