I am new to GE and I just need someone to give me a script and/or
an explaination on--

1-how to bring up text when 2 actors collide and "x" button is pressed
2-how to make it so when "x" button is pressed again text goes away
3-you can't move when text is up

thnx in advance to whoever helps

My method (http://game-editor.com/forum/tp-2151-RPG-style-talk-.html is reasonably difficult to set up, although easier when you can just copy and paste, but once it is set up, it is really easy to use.
