Drawing line on touches moved in COCOS2D

Question

I'm developing a game for iPhone using COCOS2D.

In that, I need to draw a line when user drag his finger from a point to another. As far as my knowledge is concern I need to do this in Touches Moved method from where I can get the points.

But I don't know how to do this. Can anybody help me on this?

Answer 1

- (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event  
{
        UITouch  *theTouch = [touches anyObject];
    CGPoint touchLocation = [theTouch locationInView:[theTouch view] ];
    cgfloat x = touchLocation.x;
    cgfloat y= touchLocation.y;
printf("move x=%f,y=%f",x,y);   
}

Try the above code. It will get the coordinate points when touches moved in iphone.

To draw line, use something like this:

-void draw
{
here is the code for line draw.
}

Update this function in update method.
