[GM] Text window

How do you make a text window appear?

Hold on, I'll post an example.

yea...I got game maker and stopped after 5 mins.
Noob tuts would help xD

Well, the special techniques section is made just for that. I need to remember to update it for once.

I didn't make this one.

When I try to put it in my game it says.

Make sure you copied everything. Try merging your game and the example.

You know, I am so tempted to start working in GM, but I wanna finish my RMXP game first. >_>
