I was looking through the forums and could not find how to do this. I want to find a way to print text, then scroll through it, like when you're editing a program. The text printed would be too long to fit on the screen so you have to scroll through it using the mouse_scroll event. But when you use that, it deletes the text that went off the screen. Is there any way to keep the text there?

Any help is appreciated, thanks!

The only way I can think of doing it is by storing each line in a table and have a variable storing what line your currently on, then each frame redraw the screen with the appropriate text.

I suppose if you're on CC1.6+, you could probably use the window API here. Very inefficient, but should be easy to code around.

Basically, it hands you a custom terminal object (dubbed a "window") that exists within an existing one. You can then redirect to that object and print/write stuff into it as usual. Everything you write into that window is stored in a buffer, and so if the window is later obscured, you can restore it later.

So the idea is to make a window that's larger than the display you're rendering it on - big enough to print your entire document into. Then all you have to do is respond to mouse scrolling events by moving that window up / down.

AssossaGPB's solution would require a bit more coding on your end, but it'd be far more efficient. You might find this thread useful in implementing it.

Thanks for the help.
