I loaded an object with rajawali framework... and I want to rotate it unison with camera..
Here is my code:
public Renderer(Context context) {
super(context);
setFrameRate(60);
this.context = context;
mSensorManager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);
mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
mAccVals = new Number3d();
}
public void initScene() {
DirectionalLight light = new DirectionalLight(0, 0, 1);
light.setPower(4);
mCamera = new Camera();
LoaderOBJ objParser = new LoaderOBJ(mContext.getResources(), mTextureManager, R.raw.ship_obj);
try {
objParser.parse();
} catch (ParsingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mObjectGroup = objParser.getParsedObject();
mObjectGroup.setPosition(0, 0, 0);
mCamera.setPosition(10, 50, 150);
addCamera(mCamera);
addChild(mObjectGroup);
mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_UI);
}
public void onDrawFrame(GL10 glUnused) {
super.onDrawFrame(glUnused);
}
#Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// TODO Auto-generated method stub
}
#Override
public void onSensorChanged(SensorEvent event) {
// TODO Auto-generated method stub
if (event.sensor.getType() != Sensor.TYPE_ACCELEROMETER)
return;
mAccVals.x = (float) (-event.values[1] * FILTERING_FACTOR + mAccVals.x
* (1.0 - FILTERING_FACTOR));
mAccVals.y = (float) (event.values[0] * FILTERING_FACTOR + mAccVals.y
* (1.0 - FILTERING_FACTOR));
double posx = mAccVals.x * .2f;
double posy = mAccVals.y * .2f;
mCamera.setPosition(posx, posy, 0);
double currentPosx = mCamera.getPosition().x;
double currentPosy = mCamera.getPosition().y;
mCamera.setLookAt(currentPosx, currentPosy, 0);
}
And this is my class:
public class Renderer extends RajawaliRenderer implements SensorEventListener {
}
I receive numbers posx and posy in onSensorChanged but mCamera.setPosition(posx, posy, 0) doesn't work!
I changed these:
mCamera.setPosition(posx, posy, 0);
to =>
getCurrentCamera().setRotation(posx, posy, 0);
mCamera.setLookAt(currentPosx, currentPosy, 0);
to =>
getCurrentCamera().setLookAt(currentPosx, currentPosy, 0);
And
mCamera.setPosition(10, 50, 150); to => mCamera.setPosition(0, 0, 0);
Now it works!

So I currently have a working 'Speed' power up that multiplies the speed of the player by 2. I'm trying to make a power up now that increases the score you get for picking up the GameObject 'Gem' by 2. it should increase to 20 points per gem from 10.
Currently, the power up is spawning randomly around the map within 10-20 seconds, so as intended, but the score you get for collecting the power up has not gone up to 20.
PlayerMovement Code:
public float speed = 10f;
private Rigidbody2D rb2d;
public GameObject Player;
public GameObject speedPowerUp;
public static int livess = 100;
public Vector2 movement;
public GameObject MultiPowerUp;
public static int addScore = 10;
void Start ()
{
rb2d = GetComponent<Rigidbody2D> ();
}
void FixedUpdate ()
{
float moveHorizontal = Input.GetAxis ("Horizontal"); //Gets keys that unity refers to being able to move horizontal (Set by default)
float moveVertical = Input.GetAxis ("Vertical"); //Gets keys that unity refers to being able to move vertical (Set by default) Use forces to act with RigidBody2D
Vector2 movement = new Vector2 (moveHorizontal, moveVertical);
rb2d.AddForce (movement * speed);
if(moveHorizontal < 0)
GetComponent<SpriteRenderer>().flipX = true;
else if(moveHorizontal > 0)
GetComponent<SpriteRenderer>().flipX = false;
}
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.CompareTag ("shuriken"))
{
if (livess <= 1)
{
Destroy (Player);
livess = livess - 1;
Debug.LogError (livess);
}
else
{
livess = livess - 1;
Debug.LogError (livess);
return;
}
}
if (other.gameObject.CompareTag ("speedPowerUp"))
{
StartCoroutine (WaitTimeSpeed ());
other.gameObject.SetActive (false);
}
if (other.gameObject.CompareTag ("MultiPowerUp"))
{
StartCoroutine (WaitTimeMulti ());
other.gameObject.SetActive (false);
}
}
IEnumerator WaitTimeSpeed ()
{
Debug.LogError (speed);
speed = speed * 2;
Debug.LogError (speed);
yield return new WaitForSeconds (5);
speed = speed / 2;
Debug.LogError (speed);
yield return new WaitForSeconds (Random.Range (10, 20));
SpawnSpeed ();
}
void SpawnSpeed()
{
Vector3 RandomSpawn = new Vector3 (Random.Range (-8.87F, 8.87F), Random.Range (-3.87F, 3.97F),1F);
Instantiate (speedPowerUp, RandomSpawn, Quaternion.identity);
}
IEnumerator WaitTimeMulti()
{
Debug.LogError (addScore);
addScore = 20;
Debug.LogError (addScore);
yield return new WaitForSeconds (5);
addScore = 10;
yield return new WaitForSeconds (Random.Range (10, 20));
SpawnMulti ();
}
void SpawnMulti ()
{
Vector3 RandomSpawn = new Vector3 (Random.Range (-8.87F, 8.87F), Random.Range (-3.87F, 3.97F),1F);
Instantiate (MultiPowerUp, RandomSpawn, Quaternion.identity);
}
}
Gem Code:
public GameObject Gem;
public static int count;
public Text countText;
public int addScores = PlayerMovement.addScore;
void Start()
{
SetCountText ();
}
void SpawnGem()
{
Vector3 RandomSpawn = new Vector3 (Random.Range (-8.87F, 8.87F), Random.Range (-3.87F, 3.97F),1F);
Instantiate (Gem, RandomSpawn, Quaternion.identity);
}
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.CompareTag ("Player"))
{
SpawnGem ();
count = count + addScores;
SetCountText ();
PlayerPrefs.SetInt("Player Score", count);
Destroy (Gem);
}
}
void SetCountText()
{
countText.text = "Count: " + count.ToString ();
}
}

Can anyone see the obvious mistake? I am using WP7
I changed the 'Scale' parameter in the Draw() method from new Vector(0,0) to new Vector(1,1) as obviously, having a Scale of 0 will not show anything at all.
I'm trying to draw a line based on touch event. Basically it draws line as the finger moves. I'm getting an error when overriding ontouchevent and onsizechanged. It was originally written in JAVA. I just translated it to C#. Here's the code:

Another thing. I want to make my image view from a layout as my canvas and draw the line there ontouchevent. How should I do this? Thanks!
Method name should use pascal casing.
Android.Views.View.OnTouchEvent Method
Android.Views.View.OnSizeChanged Method
public override bool OnTouchEvent(MotionEvent e)
{
}
protected override void OnSizeChanged(int w, int h, int oldw, int oldh)
{
}
Mono coding guidelines.
It's easy to show some animation within one field - BitmapField or Screen:
[Blackberry - background image/animation RIM OS 4.5.0][1]
But what if you need to move fields, not just images?
May be used:
game workflow functionality, like chess, puzzle etc
application user-defined layout, like in Google gadgets
enhanced GUI animation effects
So, I'd like to exchange my expirience in this task, on the other hand, I'd like to know about any others possibilities and suggestions.
This effect may be easily achived with custom layout:
class AnimatedManager extends Manager {
int ANIMATION_NONE = 0;

I need to display a custom icon and two hyperlinks in model pop up on Blackberry map. How can I do this?
alt text http://img689.imageshack.us/img689/2886/maplinkicon.jpg
First implement extention of ButtonField which will:
look like icon
on click will open Browser with predefined link
will use context menu
Code for such control:
class MapLinkIcon extends ButtonField implements FieldChangeListener {
Bitmap mNormal;
Bitmap mFocused;
String mLink;
String mDescription;
int mWidth;
int mHeight;
public MapLinkIcon(Bitmap normal, Bitmap focused, String link,
String description) {
super(CONSUME_CLICK);
mNormal = normal;
mFocused = focused;
mLink = link;
mDescription = description;
mWidth = mNormal.getWidth();
mHeight = mNormal.getHeight();
setMargin(0, 0, 0, 0);
setPadding(0, 0, 0, 0);
setBorder(BorderFactory.createSimpleBorder(new XYEdges(0, 0, 0, 0)));
setBorder(VISUAL_STATE_ACTIVE, BorderFactory
.createSimpleBorder(new XYEdges(0, 0, 0, 0)));
this.setChangeListener(this);
}
protected void paint(Graphics graphics) {
Bitmap bitmap = null;
switch (getVisualState()) {
case VISUAL_STATE_NORMAL:
bitmap = mNormal;
break;
case VISUAL_STATE_FOCUS:
bitmap = mFocused;
break;
case VISUAL_STATE_ACTIVE:
bitmap = mFocused;
break;
default:
bitmap = mNormal;
}
graphics.drawBitmap(0, 0, bitmap.getWidth(), bitmap.getHeight(),
bitmap, 0, 0);
}
public int getPreferredWidth() {
return mWidth;
}
public int getPreferredHeight() {
return mHeight;
}
protected void layout(int width, int height) {
setExtent(mWidth, mHeight);
}
protected void applyTheme(Graphics arg0, boolean arg1) {
}
public void fieldChanged(Field field, int context) {
openLink(mLink);
}
MenuItem mMenuItem = new MenuItem("Go To Link", 0, 0) {
public void run() {
openLink(mLink);
}
};
protected void makeContextMenu(ContextMenu contextMenu) {
super.makeContextMenu(contextMenu);
contextMenu.addItem(mMenuItem);
}
private static void openLink(String link) {
Browser.getDefaultSession().displayPage(link);
}
}
Now we can use this button control in combination with MapField, override sublayout to place button over the map:
class CustomMapField extends VerticalFieldManager {
MapField mMapField;
MapLinkIcon mButton;
public CustomMapField() {
add(mMapField = new MapField());
}
public int getPreferredHeight() {
return getScreen().getHeight();
}
public int getPreferredWidth() {
return getScreen().getWidth();
}
public void moveTo(Coordinates coordinates, Bitmap icoNorm, Bitmap icoAct,
String link, String description) {
mMapField.moveTo(coordinates);
add(mButton = new MapLinkIcon(icoNorm, icoAct, link, description));
}
protected void sublayout(int maxWidth, int maxHeight) {
int width = getPreferredWidth();
int height = getPreferredHeight();
layoutChild(mMapField, width, height);
setPositionChild(mMapField, 0, 0);
layoutChild(mButton, mButton.mWidth, mButton.mHeight);
XYPoint fieldOut = new XYPoint();
mMapField.convertWorldToField(mMapField.getCoordinates(), fieldOut);
int xPos = fieldOut.x - mButton.mWidth / 2;
int yPos = fieldOut.y - mButton.mHeight;
setPositionChild(mButton, xPos, yPos);
setExtent(width, height);
}
}
Example of use:
class Scr extends MainScreen {
CustomMapField mMapField;
Coordinates mCoordinates;
public Scr() {
double latitude = 51.507778;
double longitude = -0.128056;
mCoordinates = new Coordinates(latitude, longitude, 0);
mMapField = new CustomMapField();
Bitmap icoNormal = Bitmap.getBitmapResource("so_icon_normal.png");
Bitmap icoActive = Bitmap.getBitmapResource("so_icon_active.png");
String link = "http://stackoverflow.com";
String description = "StackOverflow";
mMapField.moveTo(mCoordinates, icoNormal, icoActive, link, description);
add(mMapField);
}
}
