Behold!

I´m going to reveal the secret about the last four digits, so listen carefully maggots!(don´t take that serious)



The little red square represents our Itemsprite let´s say it´s 16x16
The black square is our item slot which is 32x32

so for now our first 2 digits represent where our item starts in our tilesheet(let´s just pretend it start at 0 0 for this)
the next to digits represent the size of the item, here it is 16x16.

The small green square represents the 5th and 6th digit
The big blue represents the 7th and 8th digit.

in the last picture you can see that our red square starts exactly where the green one ends.
That´s our offset inside the blue square, if it was 0 0 our red quare would not be in the middle but in the upper left corner because it´s size is 16x16 and the blue one is 32x32.
This it not what we want!We want it in the middle, thats what the offset is for.
Inside of the gameengine our item is now 32x32 with a transparent border(the last picture). If we place that at 0,0 inside of our inventory slot it is positioned correctly.

so inside the youritem.txt is now an entry like this

Item_myitem = 0 0 16 16 10 10 32 32

For weapons in the third person view it´s practically the same just that you need to calculate your offset and the "real" size(last 2 digits!) relative to our starting point for the character(the whole one, the starting point is somewhere left over his head!)


Hope that explained it a little bit!


Edit: The effect of small items ending up in the upper left of the item slot can be seen, if your icon is null. The question mark doesn´t have the last 4 digits right, so that they center it inside the inventory(their purpose is only for the tutorial, that´s why before anyone asks)
