Hm. I have some problem with setting the right SubRect. I tried it as BeSaladin said. If I want to have full life it works. But if I reduce life by 1 the lifebar is gone and can't be seen anymore :-o

This is how I use it

Code: [Select]

void character::Dec_Life(int Damage,sf::Sprite& Lifebar)
{
m_life -= Damage;
Lifebar.SetSubRect(sf::IntRect(0,0,95, m_life / m_max_life * 190));
Lifebar.Move(0, (768 - 190 + ( 190 - (m_life / m_max_life * 190))));
}


m_life is an integer that represents the life. m_max_life is the maximum life you can have.

You don't use the Move function correctly. The 2 paramaters of the Move function are offsets.
Try using the SetY function instead, as written in BeSaladin pics.

Move function isn't like SetX and SetY functions becauce move function increase X and Y by the values u give in :!:

For example : If u use Move function of a sprite that have x= 800 and y= 500 as the following : sprite.move(800,900) then the new coordinates would be x = 1600 and y = 1700.
And u will not see it probably in the window ^^. :P

 :arrow: I council u to avoid calculating in parameters as u did before try this ^^ :

Code: [Select]

int y = 768 - 190 + ( 190 - (m_life / m_max_life * 190));//
Lifebar.SetX ( y ); //this is better ^^

Even though it seems there's something wrong :-/ No matter how much the life should be reduced. No matter if life is 0 or 50 or something else it always sets the position to 768!(Screenresolution: 1024x768)

If both m_life and m_max_life are integers, m_life / m_max_life will always be equal to zero. You need to cast at least one operand to float, or write m_life * 190 / m_max_life.

But what we have now looks like this -> http://www.youtube.com/watch?v=h4BybgiF-0k

I think I have to do it the other way round. Now we cut off the bottom and set the sprite lower. But it has to cut off the top!

I messed around with different rects, but somehow I don't get it O_o

If u see this line of code ^^ then it's so logical . :)

Code: [Select]
Lifebar.SetSubRect(sf::IntRect(0,0,95, m_life / m_max_life * 190));

Try this :

Code: [Select]
Lifebar.SetSubRect(sf::IntRect( 190 - ( m_life / m_max_life * 190 ) ,0,95,190));

It should work ^^.
