Good Morning/Evening, i have just 2 easy question.
1) What editor you use to write code?
2) i'm trying to program some stupid games,but i have a problem, i want to make an image move up 50 pixel and then, after 2 sec., the image have to go down, but i don't know how let the game to wait 2 sec, i have alredy tryed to use sleep function, but the game just freeze for 2 second, i need a code that count seconds.

I hope you understand what i wrote, thanks for the help.

1) Editor choice depends on operating system. On Windows, I prefer Notepad++.

2) You need to read up on how dt works. In the above example, I add the time passed to a variable (timepassed) and when the time passed is greater than or equal to 2 seconds (our interval), I do three things. First, I take the now-excess seconds off, then I move the img by adding a predefined move variable (notice that move is negative, since up is negative in the Y axis). Lastly, I make move negative itself, so that in two more seconds we will go in the opposite direction.

You can use just about any text editor to open and edit .lua files, But i'm with tentus on this, Notepad++ is the shit. You can get an auto complete configuration thing for it here And instructions on how to install it here

Favourite text editor: Sublime Text 2 (free beta)

Also agree w/ tentus; start using dt from the very beginning; it's essential. (I made the mistake of ignoring it for a while)
