Mainly because of this problem.

where i can not simply open a new gui with container because I can't (and some guy that works with me can't either > very advanced coder he is) because of server and client side.

 

if you have taken a look at the problem, and can tell me that the problem is not server or client, please tell me, and then ignroe this post.

 

but it would be awesome to be able to open a gui without a block or item, just a key, or the way I did it, with ClientTickHandler.

 

Thanks for reading

There are many ways you can do it, you have all the imputs a coputer has access to at your fingertips. You just have to trigger it, not a forge thing.
