Widescreen Script Help.

Hey, everyone. I need some help with the repost of this widescreen script posted by Selwyn.

The script is here:

#==============================================================================
# â–  WScreen
#------------------------------------------------------------------------------
# 　By Selwyn, Widescreen effect script
#   released the 1st of February
#
# This script allows to give some cutscenes a 'widescreen' effect.
#
# The script is off by default (when you first start the game).
#
# By default, when the widescreen mode is turned on, it hides one tile at the
#  top of the screen and one tile a the bottom.
#
# By default, the transition_speed is 3, you can change this value just a
#   few lines below
#
# To turn the script on, put 'WScreen.turn_on' in a call script command of
#   an event. Turn it off with 'WScreen.turn_off'
#
# To change the number tiles hidden in widescreen, use the following function
#   in a call script command of an event :
#   'WScreen.size = NUMBER'

I keep getting the error:

undefined method 'rect' for nil:Nilclass on line 198.

Line 198:

if @viewport1.rect.height > 480 - (WScreen.size * 64)

I know what the error means but I don't know how to fix it. Would anyone mind helping me out? Thanks in advance.

Have you edited anything in this script ?

A demo is helpful BTW haa...

It looks like your @viewport1 is not yet initialized...

 

[Grandor]

So, how would I fix this? I'm getting more then one error, it says my undefined bitmap error from Spriteset_map, I know for sure that the bitmap method is actually part of the RGSS. So, I have no clue why it does that:

Error:

Their looks to be nothing wrong on line 94:

Line 94 of Spriteset_map

if @panorama.bitmap != nil

 

[knmt]

please upload a demo , I don't want to guess out your problem hix...

 

[Grandor]

Well, actually the problem doesn't persist when I create a demo, however it does on my original game. It was working only a few days ago...perhaps it's conflicting with another script?

 

[knmt]

Land of Arcania ? The name is pretty familiar...

anyway , what is the difference between your demo and your original game ? if you create a demo which is not refering to the problem of course the problem won't persist . You haven't posted the game in the New Project Section so...

Forum's Server movement is near btw...

 

[Grandor]

I have fixed the problem by my self. It was interfering with a mirror script I had. Thanks for the help!

 

[knmt]

Congrats !

anyway , may I know what your problem is ?

 

[Grandor]

As I said it was intefering with another script that rewrote Spriteset_Map, as soon as I removed it, the Widescreen Script could work, and thus that's how it got fixed.
