How do I advance backdrops pressing the space bar?
From OHRRPGCE-Wiki
With textboxes[edit]
The simplest way to do this is to make a series of text boxes with backdrops, and link them together. Display the first text box, and the player can press the use button to advance through the series of screens.
With plotscripting[edit]
If you prefer to do this with plotscripting, you can use the show backdrop command and the wait for key command.
show backdrop (10) wait for key (use key) show backdrop (170) wait for key (use key) show backdrop (171) wait for key (use key) show map
