Simple script to get a little fancy with the camera!

Using this Script​

You've just got the two calls here!

pbZoomMap(goal,speed,zoom="in")


Goal is the zoom level that you want to reach. Remember that a normal zoom is 1- think of it as "1 = 100%". A goal of 2 would have your map zoom in to 200%.

Speed is the amount that the zoom increases/decreases by per frame. If you're doing an amount less than 1, remember to put a 0 before the decimal- 0.5 instead of .5, for example.

Set zoom to "out" to zoom out. (speed should still be a positive number)

pbDisposeZoomMap gets rid of the zoom. Note that it does so abruptly, without zooming out- it's mostly just there for cases like exiting a map, where the fade to black will keep it from being too jarring. If you to remove it while the player's still on the map, you should zoom back out to 1 through pbZoomMap.

Please note that this is only for zooming in from standard view and zooming back out from a zoomed-in view- it currently cannot zoom out any further, and I don't think that's actually possible to do. (I'll look into it later, though.)

If you're using a pause menu with its own GUI- for example, bop's HGSS menu- you should delete the section that starts with "Pause Menu Rewriting" to avoid conflicts between the two.

Because the zoom is stored in $game_temp, it's deleted when the player closes the game. If you want a map to be zoomed when the player has control, you should probably have a parallel process or autoplay event, so that players who save on the map can reload their game without breaking the zoom.
Future Goals​
  • I... may need to fix the save window as well, I'll get that soon.
  • I'm pretty sure zooming out is impossible, but I'll write it here in case I ever get around to the possibility.
