Hello! I'm working on my mod, and I want to know: how to add energy bar into container screen, as it done in for example, industrial craft 2, or themal expansion?

I have an idea: may be use this.blit twice for first, to render empty bar, and then with offset render this.blit fulled energy bar?

 

 

Thanks for answer anyway!!

You can have the empty bar in the background texture and just blit the energy afterwards.
