Solved Input GUI Error

Please help me, i'm getting an error with this API.

I added the api to my plugins build path » i added the API in my plugins folder » i added this line to get the API getting worked

Code:

InputGuiAPI api = (InputGuiAPI) Bukkit.getPluginManager().getPlugin("InputGui");

But it's not working!
Does anyone know how to fix this?

Error in the console:

Console error (open) Console error (close)

[11:54:09 INFO]: [InputGui] Enabling InputGui vdev-SNAPSHOT
[11:54:09 ERROR]: Error occurred while enabling InputGui vdev-SNAPSHOT (Is it up
to date?)

I've never used InputGuiApi, so, i'm not completely sure, but from the logs you posted, perhaps it depends on ProtocolLib.
Do you have it on your server?

 

@WinX64, yes i've got it in my server. Here is a picture what i see when i type /pl

@CheesyFreezy
you are running this api on a 1.8 server. in 1.8 these packets are not longer supported for opening an commandblock or something else. it will make errors. you cannot fix it because it is now all client side. if you want an other option signs are still supported

 

@crolemol how do i do that?

 

@CheesyFreezy
i don't know i have to find this for a plugin i am writing but i can't find it for 1.8. you should google it yourself

 

@crolemol, i'll search for it. If i found something i'll let you know
