That just looks like a laptop falling apart... Especially the one on the right.

A samsung galaxy note is a tablet, not a smartphone (or at least, there are tablets that are called samsung galaxy note)

But basically, people buy tablets because they're a lot lighter than laptops. And a tablet doesn't need much space in a backpack, where as a laptop takes up almost half of the backpack. Further, there's the battery life. Most laptops have a very crappy battery that only manages to power it for an hour or two, while a tablet can often last a lot longer witouth needing a recharge. This makes it very suitable to use it in a train, bus, boat,...
An other argument for tablets is that they have tons of free or cheap games, that are very aesy to download and install.
And for the touch screen, it makes it look and feel more modern, and it makes the device a lot more user-friendly. Even very young children (from 4-5 years) can use a tablet because of it's touch screen.
Finally, an other important factor may be that you can get them for free in a lot of places. And some other people may buy them because 'everyone' has got one these days.

Oh, and by the way, they are useful to have an even surface to move the mouse on when your using your laptop while sitting in the couch (yes, I did that once).

I just decided that it might be better to update this topic a bit more often. That way, you guys know how the project is coming along, and for me, writing about it makes me more motivated to do more.

Since my previous post, I've done a lot of programming. This is what I've done:
 - I have created a crafting interface. This works by having a central item, and on the sides of the item, you can add more items. When you've laid out a combination that matches a recipe, you can craft the item. There's a textbox next to the craft button to decide how many times you want to craft, and the result (item + amount) you will get after crafting one time is displayed. Next to the crafting grid, there's a list that contains the recipes that can still be made by expanding the already present items on the grid.
The only thing left to do here is making the interface give you hints abouth how to make a recipe selected from the list of possible recipes. Adding/moving items in the crafting interface or between the inventory and the interface is done by drag&drop.

 - The entity system is slightely improved. Okay, this doesn't really change anything gameplay-wise, but it makes it easier for me to add more entities with having to worry less abouth crashes (in the previous system, they were poorly initialized), and it made it possible to add:

 - An interaction system! A simple interaction system was already present in previous versions, but this one is a lot better. Firstly, it allows the player to interact by using items on entities. This is done by dragging an item from the inventory and dropping it on the entity you want to use it on. Secondly, the interaction system is now entity-based, which again makes it easier for me to add new ways of interacting with new entities, without having to worry a lot abouth typing mistakes. And finally, the interactions with entities give feedback, which makes it possible to make interactions do more than just change the entity. For example using a key on a door could destroy the key while opening the door (zelda style).

 - You can chop down trees again! This feature has also been present in previous versions, but it has been temporarily taken out because I converted the tree from being a model with interaction data stored in it's name and a controller class (for usage in the old interaction system) into an entity. The tree entity also has the added feature of supporting multiple types of trees with different propperties (like the time needed to chop them down), and it can react differently on different types of axes. The way you cut down the trees has slightely changed as well: instaed of right-clicking them with an axe in your inventory, you have to drag an axe from your inventory and drop it on the tree.

I've also fixed some things in the multiplayer controller class that were poorly initialized.

That's what I've done in that time. And as soon as I've improved the graphics of the new interfaces, I'll post some screenshots or a video.

I have cleaned up mine. Is it ok like this or should I remove the dead project? I let it in for now because multiple people have asked for the source code.

The awkward moment when you're in a place where they speak a foreign language and say something in that language you've searched on the internet (something like asking the bill in a restaurant), then get an answar in that foreign language and you don't understand anything of it...

True story for me, and maybe some of you recougnize this as well.

I just call it "Mijn grafisch rekenmachien" (="my graphing calc"), or, when it's clear that I'm talking abouth the calc, "da ding" (="That thing")
