Topic category: Help with modding (Java Edition)
Hello everyone! I am a new user (in terms of account age) that has been working on a miscellaneous mod for a while now, and I had an idea to make a 'terminal' of sorts, where you can enter a message into the block, select another terminal anywhere in the world and send the message along with any items.
Each terminal would have it's own unique ID starting at 0 and counting up to some arbitrary value such as the 8-bit integer limit (255). To send the message, one would enter the message in the text box, and in the next text box, they could write the ID of the terminal they wanted to send it to and then click the send button to send it. The message would then appear in the receiving terminal's receive text box, along with necessary items.
The thing is, I have no idea how to do this, and even something as simple as making a button to run the /say command in a GUI is beyond me, so any help would be amazing to a new user like myself.
