[HELP]Progress bar does not work as intended

[Pingubro]

Good evening,

I have come to another problem with my GUI. This time it is the Progressbar

I have looked at the code of the Furnace and mimiced it a bit so i got it working with

the powerbar an the boot thing. But when the progress bar becomes active, it totally messes up my GUI.

 

GUI

Container

TileEntity

 

Thank you

Can you describe in some more detail what you intend to happen? Are you wanting to fill in the arrow white from left-right like a vanilla furnace does, or something else?

[Pingubro]

Yes that is what I am trying to do the arrow should fill white and I looked in the furnace how it is done. This works somehow for the energy and the startup indicator but not for the arrow.

When the arrow should be painted this happens.
