I know the physics thing .......but i don't know how interact both the things......
I mean i can make a class of VECTOR working for 2D, it can find the dot product, addition, subtraction and all.
But i don't how interact this class with the circle to find collision detection....

This code is running good ... but I'm unable to make the ball fall down.
Plz tell what changes i should make to create gravity effects???

Somewhere in your game loop, try:
ySpeed += 0.5f;

I need pageviews! most fun profile ever :)
I have changed these lines of code
Now the ball is moving in y-axis only...
And William where i should make these changes u r talking ??
GLfloat xSpeed = 0.0f; // Ball's speed in x and y directions GLfloat ySpeed = 0.05f;
And William where i should make these changes u r talking ??
ySpeed += 0.5f;

Pretty much anywhere in your game loop, if you want an exact position, I would put it directly before the lines:
// Animation Control - compute the location for the next refresh xPos += xSpeed; yPos += ySpeed;

Thanks William it is working......
NOW I HAVE A QUESTION, IF THE BALL DETECTS ANY COLLISION IN BETWEEN THE SCREEN WILL IT MOVEIN X-AXIS OR NOT????
I MEAN I SET THESE LINES OF CODE
[edit]
which means ( GLfloat xSpeed = 0.0f; ) this will effect the ball to move in x-axis if the ball detects any sloped line ....right?
[/edit]
// Animation Control - compute the location for the next refresh ySpeed -= 0.04f; xPos += xSpeed; yPos += ySpeed;
I MEAN I SET THESE LINES OF CODE
GLfloat xSpeed = 0.0f; // Ball's speed in x and y directions GLfloat ySpeed = 0.001f;
which means ( GLfloat xSpeed = 0.0f; ) this will effect the ball to move in x-axis if the ball detects any sloped line ....right?

CHECK THIS OUT , I HAVE MADE A .bmp FOR U.
[EDIT]
NOW U CAN SEE THE SLOPED LINES TO WHICH THE BALL IS INTERSECTING,
NOW AFTER INTERSECTION THE BALL WILL TRAVEL BOTH THE AXIS i.e X AND Y.
I WRITE THIS LINE IN MY CODING
WHICH MEANS BALL HAS ONLY ySpeed BUT NOT xSpeed, WHICH FURTHER MEANS THE BALL WILL MOVE IN ONLY ONE DIRECTION i.e Y-AXIS.
U GOT ME NOW?
