[1.7.10] Need help with GUI

[MikaXD]

Hey,

 

I created a GUI which can be open through pressing a key (I'm using the KeyInputEvent). I have already registered a gui handler and actually everything works perfect.

Now I added a button to my gui which gives the player an apple (only an example). This works, but if you right click the apple it disappears. If I open my GUI in the KeyInputEvent, it only calls the getClientServerSide()-Method of my GUI-Handler. But what I need is the server side, too. If I open the gui in the onItemRightClick()-Method of any item, it works.

Can anyone help me?

 

PS: I don't have much idea of sending packets...

Oh, no, I've almost expected.

Ok, but currently I cannot find any new tutorials, which are not outdated. Is there any open source?

Thanks!
