How to program this 2 Systems?

Hey all

2 Questions about creating 2 Systems:

1) How is it possible to program a fullscreen inventory save/load system in Jass?
It should save all carried items and a variables from the inventory (itemstats, itemabilitys, ....and so on)

2) How to create a Shield system in Jass like the shield spell from wow (power word: shield)
It should protect the hero from damage without hp reg or other stuff, just for example: shield has 500 hp so it protects the hero from 500 damage.

thx almii*

1) You can take a look at existing fullscreen inventory systems (you can find some examples here and here), but it is possible none of them matches how you want the system for your specific map to work, in which case you'd need to write a similar system yourself. Note that such systems tend to be quite large and convoluted, so this isn't a particularly easy task.

For the save/load part, it should be reasonably easy to write something based on codemaker.

2) This is a lot easier to do thanks to damage modifiers.
