How do I script a GUI that appears on screen when I touch a brick? For example, or what I'm trying to make, I want towalk onto a brick, then a GUI will pop up on everybody in the servers screen with a countdown GUI, from 60 seconds to 0, and at 0 the GUI should disappear.
I'm completely new to scripting with GUIs and Lua in general, and I'm completely lost.
The brick that I want to touch is named "CountdownBrick."
I don't have the GUI done, because I am not sure how to insert it on screen when stepping on "CountdownBrick."
