[Solved] Switch inventory pages using arrow keys

[Warseeker]

I want to give my hero 3 inventory pages and the ability to switch between them using the left/right arrow key. Let's say I press the right arrow key, all the items I have on my current inventory (let's call it inventory 1) will be stored and removed. So now I have an empty/new inventory (let's call it inventory 2)

If I press the left arrow key, all the items I currently have on inventory 2 will be stored and removed and all the items I had on inventory 1 will be restored.

So my question is how can I do that?

I made an exampel on how to do it. It might not be a good way but it is a way.
This would allow 1 unit per Player to use the system. A good other way would be a hashtable, then multiple units per player could use the system. You could also use unit Indexing but for this example I went with Playernumber.
I hope I didn't make any maths errors.

Inventory v2.1a 's Bag library could be modified to work with arrow keys.

I can't open the map, I suppose it was made with the latest patch? Can you post the triggers instead?

I'm not familiar with JASS sadly. The system looks very complicated :/

        • Set VariableSet Inv_Items[(((Inv_Page[(Player number of (Triggering player))] x 6) + (Integer A)) + (((Inv_PageLimit + 1) x 6) x ((Player number of (Triggering player)) - 1)))] = tmpItem

        • Item - Show tmpItem
        • Hero - Give tmpItem to Hero[(Player number of (Triggering player))]

To add more players just add the key event to left and right. You also should check if the unit is alive.

Worked like a charm! Thank you so much

What do you mean by "check if the unit is alive"? Will it cause a problem if the hero dies?

It would mess with your page and unhides the items. You can just add the unit is alive condition to "Inv Left" and "Inv Right".

Oh okay, thanks again!
