Hi everybody, I'm pretty sure someone has already solved the problem I've encountered .

I'm trying to create a health\mana\xp bar object but got stuck in the visualization aspect of it. What is the sane way of implementing variable length gradient rectangle? Creating the image from hundreds of small 1 mm long repeating chunks sounds nuts, but what are the other options?

Just render a part of the image (eg by using texture coordinates).

Just throwing this out here.

In Christopher's example, make maxHP a float, otherwise it will be imprecise if the bar width is an odd number.

Copying Christophers code because im lazy:



This will make the healthbar change from green to red as the health decreases.

I did something similar.



It's shorter and I can put it in update instead of render, and only putting g.setColor(playerHealthBarColor); before my g.fill(playerHealthBar); in my render method. It makes a very smooth change in color.

Guys, thanks for all the replies, that helped a lot .
