Disappearing Bars

[Evilupstart]

Hi, this is my first time posting in this section.
I'm using a hp/sp bar system that displays on the map in a HUD. This is the script I'm using at the moment. It's by Slipknot and was posted a long time ago, before the hack, so I didn't want to go necroposting something that hasn't been touched in nearly a year. The original is here.. http://www.rmxp.org/forums/showthread.php?t=2384&page=2
I've edited slightly to meet my needs but I'm having a problem with teleportation on maps. When I teleport the bars disappear and wont return until I've entered the menu and exited it again.
Here's the edited script..

I don't know what's wrong with it or if I've done something to it to make it do this. I'm also using Ccoas UMS, Caldarons 1 Hero CMS, Prexcraft, Selwyns Minimap and Lambchops Intro Screen. I'm hoping these other scripts aren't causing conflict because it's taken me a little while to get them to work together.
Another problem I'm having is with displaying variables set by events in the menu. I want to display a variable ([0001]) where the Steps section would be saying "Coins: x/100" where the x is the variable but I cant get it to display.
I have this so far..

  def refresh
    self.contents.clear
    self.contents.font.color = system_color
    self.contents.draw_text(0, 0, 64, 32, "Coins")
    self.contents.font.color = normal_color
    self.contents.draw_text(64, 0, 144, 32, "/100" )
  end

..where it says "/100" I want it to display the contents of Variable [0001] before it.
Thanks to anyone who can help me with these problems.

self.contents.draw_text(64, 0, 144, 32, "#{$game_variables[1]}/100" )

 

[Evilupstart]

Excellent, thank you.

Now if anyone else wants to help with my other problem I'd be so grateful.

 

[Evilupstart]

Can't anyone help me with this? It's kind of important because I don't want to have to tear my hud/stats apart to add a different script.

 

[Evilupstart]

Bump. I've noticed that the bars disappear on the original script when you transfer player :/.. can't anyone help me? I just need the bars to stay after player transfer.

 

[G-man]

it's probably got something to do with the update method

 

[Evilupstart]

Yeah, thats what I figured since they re-appear after exiting the menu, but I'm not really a scripter I'm just editing them to my basic needs and I can't figure out how to add an update after transferring player :/
