life bar
There is no general solution to a problem like this. But here is some useful information:
If you want to do it the object oriented way, you may create a HealthBar class:
To create a visual health bar, use GreenfootImage to set the objects image. Here are some important methods:
For the actual health loosing logic, I can give you little advice; it very much depends on your usecase. The general idea is that you decrement the value in your health bar when you do something that looses you health, and possibly increment it from time to time to have regeneration.
public class HealthBar extends Actor {
private int health = 100;
public void getHealth() { return health; }
public void setHealth(int health) {
this.health = health;
}
}
// Create an image with a specified width and height (the image is transparent by default) GreenfootImage image = new GreenfootImage(102, 12); // Set the color for subsequent operations image.setColor(Color.RED); // Use predefined constants or custom rgb values image.setColor(new Color(50, 100, 150); // Draws the outline of a rectangle with top left at coordinates 0/0 and a size of 102x12 pixels image.drawRect(0, 0, 101, 11); // Fills a rectangle with the top left at coordinates 1/1 and a size of 100x10 pixels image.fillRect(1, 1, 99, 9); // Set the image of the current actor to the specified image setImage(image);
