Diablo 3 Resource Bubbles

I wrote a blog post about recreating Diablo 3’s resource bubbles (as talked about at https://simonschreibt.de/gat/diablo-3-resource-bubbles/ ). You can find the blog post, with a link to a zipped up working example, at https://www.gamedev.net/blogs/entry/2263632-diablo-3-resource-bubbles/

The linked example includes GLSL shader code to implement the effect. A shader uniform, Level, is specified in the range of 0,1 and determines the level of fluid in the bubble. A scrolling noise texture provides lively surface froth for the top of the fluid. The bubble could be rendered to a texture for actual display on the UI, though the example doesn’t include such functionality. It’s an example of a relatively simple effect that has pretty nice visual impact.

I got tired of trying get UI blending working properly for hours on end… and finally gave up. Instead, I moved ahead and added a custom shader functionality in UI and UIElement. See the pic below. This basic class that I created basically parses a mdl file and creates UIBatch from it, creates shader from uses material like any other class that deals with mdl file, and renders at UI render cycle. Just got the initial phase done, and no where near polished.

edit: bah, it doesn’t create shader, but used material.

@JTippetts, I got most of the features worked out including something that I needed for my game. And since you provided the bubble resource I’m guessing that’s something you want/need to add to the game you’re making. The code that I’m working is in my personal sandbox but I can integrate it to 1.7 and email it to you.

Here’s a sample:
