error in player movement script

[Desbrina]

I'm using this script made by SephirothSpawn found in the topic below

http://www.rmxp.org/forums/showthread.php?t=10760&highlight=movement

The problem is if you press F12 in game and then try to load a new game it errors saying

Script 'Disable player Movement' line 25:SystemStackError occurred.
stack level to deep


this is line 25

    seph_ispsystem_gameplayer_init

this is the whole code

#==============================================================================

  end

    # Original Update Player Movement Unless Movement Disabled
    seph_ispsystem_gameplayer_upm unless @disable_player_movement
  end

  #--------------------------------------------------------------------------
  def update_action_trigger
    # Original Update Player AT Unless Movement Disabled
    seph_ispsystem_gameplayer_uat unless @disable_player_trigger
  end
end

The custom scripts i'm using are

SDK Version 2.2 Parts 1-4
Edited Version of Scene Title - Extra command for test map
Skills + variables http://www.rmxp.org/forums/showthread.php?t=24268 - Does it even without the script so doubt its that
Scene_Realm - My own one, does it without the script so doubt its that but can post it if requested

Thank you for help you may give

Many scripts have problems with F12. I think its a RMXP program bug, not a script bug. Many scripts when you reset it in test mode, it causes you to be unable to move.
Just avoid having to press F12. Close and restart your game in test mode instead, or, remove the script until your game is done.

In the SDK topic, Trickster posted an F12 bug fix. here is a link to it: SDK F12 Bug Fix (Unofficial)

do i just add that as another script?

 

[Draycos Goldaryn]

yes, just add it above the SDK.

 

[Desbrina]

if i put that script below the SDK i get an error (same on every script, what script it errors depends on where it is, but its always the same error)

undefined method `update` for nil:NilClass


if i put it above it i get the original error
