Hey,

I have some code for bouncing. It works well most of the time but there are some issues at times. Does this look good?

Help with Code Tags
C++ Syntax (Toggle Plain Text) 
  1. if(m_position.y+m_height >= paddle->GetY() && m_position.y <= paddle->GetY() + paddle->GetHeight() && m_position.x+m_width/2 > paddle->GetX() && m_position.x+m_width/2 < paddle->GetX() + paddle->GetWidth())
  2. 	{
  3. 		m_velocity.x += paddle->GetMoveX()*(0.25);
  4. 		m_velocity.y *= (-1);
  5. 	}
  6. 	else if(m_position.x+m_width >= paddle->GetX() && m_position.x <= paddle->GetX() + paddle->GetWidth() && m_position.y+m_height/2 > paddle->GetY() && m_position.y+m_height/2 < paddle->GetY() + paddle->GetWidth())
  7. 	{
  8. 		m_velocity.x *= (-1);
  9. 		m_velocity.y -= paddle->GetSpeed()*(0.15);
  10. 	}

The code's in C++, and the scope is within the ball class. So things like m_position and m_width refer to the ball, and paddle->GetX() and paddle->GetWidth() refer to the paddle. if you'd like me to give it in more basic pseudo code let me know.
I'm a student. If my statements seem too absolute, feel free to coat them with "In my opinion..." or "I believe...".
