[1.7.2][SOLVED] Problems with gui Progress bar

Jacky2611 · April 13, 2014

After i realized that i am an idiot i tried to add a nice gui and a progress bar to my furnance.

No errors, everything looks fine, minecraft starts with 0 errors, i can open block, but energy bar doesn't change...

After trying around a little bit i think that my energy is never set to anything else than 0, but my update function says that it is increasing.

The client and the server are desynchronized. You should look into getDescriptionPacket() and onPacketData().

You should look into getDescriptionPacket() and onPacketData().

The description packet is definitely not the right tool for a progressbar.
@OP Look at ContainerFurnace on how to handle progress bars.

Ups, forgot to post the container...

public void updateEnergyBar
Where do you call that method? And if you don't call it, how do you expect it to be called?

Maybe i should start a petition to add this smiley:
