That's very strange, I copied the code and it works perfectly when I run it in my Editor. Mybe it's because of the line platform.apilevel = "2.0", that doesn't have any effect in the Editor because it's not on the first line on the whole program and it can cause errors if you do it anyways. Are you sure that you are using the file "Jens' Script Editor apilevel2+"? What error does it output?

@AnToX98: Yeah, I had the same idea when I made that insert function, but I forgot it later, thank you very much for this suggestion, I'll add it to the list!

I just started to work on version 2.0 and those are the features/changes I want to include:
- full console to see output of the print function
- User Skript runs on its own page to switch to the editor/console screen for debugging
- console runs on its own frame so that you can copy it and attach it to the running skript screen
- (as suggested by adriweb) an autocompletion popup
- (as suggested by AnToX98) a customizable "insert" function and customizable syntax colouring
- faster rendering (I'll have to do some research there, maybe if I'd use textures for letters or render them with gc:drawPolyLine(...))

Please tell me what you think of those features and feel free to make proposals if you have any suggestions for the new version!

PS: The development of this version 2.0 will be much slower! (school started again and I continued working on Minecraft 2D...)

!!!Update!!!
Version 0.8 is now attached to first post

New features:
- mobs:
  - passive animals: pigs, cows, sheep and chicken:
    - they only spawn on grass at daytime
    - they move around randomly
  - aggressive zombies:
    - they spawn at night and in shadow but not in the range of a torch
    - they will run towards you and attack you (if you aren't too far away)
    - they burn in the sun
  - they can swim, drown, and take damage from falling and lava
  - click on mobs to attack them and they'll give you items
  - they despawn if you are too far away
  - they won't be saved yet
- doors:
  - click with [(-)] on them to open/close them
- beds:
  - click with [(-)] on them to sleep
  - it must be at night and the bed must be in the range of a torch to sleep
- weapons:
  - use them to effectively attack mobs
- worldsize selection:
  - you can now select small(100x100), normal(200x100) or large(400x100)

Improvements:
- you can now select blocks via the numpad (for clickpad models)
- you can now control nearly everything with a clickpad nspire
- extremely fast blockselection in fast graphic mode (toggle with [v]) via partially frame updates
- rendering nights is now much faster
- improved graphics
- various bugfixes

Please read the controls.txt, the ingame help is not complete yet!

PS: I don't know if there are still problems on greyscale models, I changed very much on the game and the textures!

Maybe it's possible to extract stored variables out of .tns files? The code is saved as plain text in "jsefYOUR_NAME" (If you named your file "omnimaga" then it's stored in "jsefomnimaga")
I should include those tips in future versions in the redme.txt

PS: I have a completely unrelated idea: How about an "empy tns file" where you can paste your code and then it will forever execute the pasted code?

Thanks, I see, the most is ok, but the shadow texture doesn't look right, but I have no idea why... Does anyone have an idea? Shadow texture attached.

@Legimet: Yes, do this:
1) Copy the script editor tns to a pc and run it with the student software/emulator
2) Load your file
3) menu==>code==>select all
4) press ctrl+c
then you can paste it anywhere as plain text and it is compatible to every text/script editor
