How do I make a life bar that goes down slowly, that is, I have 100 life and it goes down 10 times and uses images as life, that is, I have a line that is made by images and when a time passes, like, 30 second travel a percentage of your life

Use an int time counter field. Increment it every act step. Use the modulus operation to make it loop back to zero at a value of 1800 to approximate 30 seconds of time. Test its value after incrementing. When its value is zero, subtract from life. The bar can be treated as being from 0 to 10 since you want it to jump by 10s. If you display the value as text as well, just multiply by 10. Update bar image only when its value changes.

With the int field: 
private int timer = 0;
It might look something like this: 
timer = (timer+1)%1800;
if (timer == 0)
{
    bar.setValue(bar.getValue()-1);
    if (bar.getValue() == 0) Greenfoot.stop();
}
