[1.8.9] GUI not drawn

Posted May 23, 20169 yr

Hi,

I have create a custom crafting table (following TheGreyGhost's tutorial) and now I have the problem that my gui is not drawn. This problem generated two questions:

[*]Is it neccesary to have a TileEntity? Looking at the Workbench it is only a Block and the Container is holding the inventory for crafting and result.

[*]The drawGuiContainerForegroundLayer() and drawGuiContainerBackgroundLayer() are never executed, but GuiHandler works fine and returns a Gui (client side). Any idea why?

Thanks in advance,

McRaichu

It doesn't work, I don't know why.

yep, sounds right. But for now that is not important (the workbench does the same ). And i tested and it returns true and still the gui doesn't show.

Bad pathfinding for big mobs (1.21.1)

Processor failed, invalid outputs

Sorry for necro, but this is one of the first search results for this issue. Possible cause is Forge checking for zlib (the expected hash) and not accepting zlib-ng (the actual hash):

https://github.com/PrismLauncher/ForgeWrapper/issues/3

One possible workaround (aside from swapping zlib-ng for zlib which might cause other problems on your system) would be to use the prism flatpak.

Bad pathfinding for big mobs (1.21.1)

Well I was mainly trying to figure out whether or not I was doing something wrong and if it could be fixed by just adding something (e.g. maybe I was missing an Attribute or something like that), but if that's not the case then my only option is to use custom pathfinding. If someone has one that functions and is willing to share it, then I'd gladly use that instead of suffering through making my own.
