UIImage Ball collision on specific direction of another uiimage causes it to deflect

[saiprashanth]

The Problem is very simple and weird for me...

I have created a UIImage of a ball and another UIImage of red gem...

when the ball collides it has to pass through it and increase the speed... The speed is increasing and its working ...........but

if the ball collides from the bottom it gets deflected back and the speed is changed... if the ball collides the image from top the speed gets increased and the ball continues to move without any deflection....

the speed is working and collision is working..but the problem is if the collision takes place on the top of the gem it does not have any problem...but ... if it collides from bottom the speed is getting changed but the ball gets deflected instead of passing through the gem ??

probably the problem is on your code. show it.

Thanks dany for ur time...

i have added the code below


if (CGRectIntersectsRect(ball.frame, red.frame) && red.hidden == NO )
{

if( redpass == false)
{

score1 += 2000;
scorered+=1;

redpass = true;
red.hidden = YES;

kBallSpeedX = 6 ;
kBallSpeedY = 6;


ballVelocity = CGPointMake(kBallSpeedX,kBallSpeedY);



}

}

if (CGRectIntersectsRect(ball.frame, red.frame) && (redpass == true) )
{

score1+= 0;
scorered+=0;
red.hidden = YES;

}

else {

redpass = false;

}



this is the code for collision check and speed increase....
