Interface ItemDecorator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ItemDecorator

Draws over an item wherever the game draws it in a GUI (inventory slots, the hotbar, a held stack...), after vanilla's own decorations: the durability bar, the cooldown and the count. An item gets one by implementing DecoratedItem on its class, which registers it by itself.

public final class FlaskChargesDecorator implements ItemDecorator {
    @Override
    public void extract(GuiGraphicsExtractor graphics, Font font, ItemStack stack, int x, int y) {
        int charges = FlaskItem.charges(stack);
        for (int i = 0; i < charges; i++) graphics.fill(x + 2 + i * 3, y + 13, x + 4 + i * 3, y + 15, 0xFF55FFFF);
    }
}

An item is 16x16 at (x, y). To draw at the item texture's own resolution, scale the pose (a 32x32 texture's pixel is half a GUI pixel) and restore it. To leave vanilla's bar out, return false from the item's isBarVisible.
