unity3d - Data structure for irregular grid -

-

I'm wondering what is the best data structure for the grid in which different size rectangular / square game map sectors are. I need an XIG object which is within the grid by simple Xyz coordinates.

Enter image details here searched for KdTrees, but they get the closest thing I also get trees / gaps in the segment, but there is some information about Cheers.

This is you can use an octree, you can start with a rectangular parallel pip In which the entire region is ((0, 0, 0), (x, y, z)) (this is the root of the tree). In the next step, divide it into 8 rectangular parallel pipid ((0, 0, 0), (x / 2, y / 2, z / 2)), ((0, 0, z / 2), (x / 2, y / 2, z)) and so on). These are 8 rectangular parallel piped children of origin. Repeat the tree for each of them when a rectangular parallel is completely within an area, then recursion should be stopped (hence it becomes the leaves of the tree).

To answer a question, start with the root of octree and go to a proper child until you reach the leaf.

It is possible to adapt the KD tree to solve this problem. This idea is similar to the one described above: Divide the space into two half-dimensions, create a tree for each of them. The case of recurrence is also the same: Once the current sub-space is only within one area, then recursion should be stopped.

There are two panels in my JInternalframe. I want to add TopPanel to Jtree to nominate another. But I can not add Jaitari to the top of the panel. Please help me in this piece of code: DefaultMutableTreeNode root = new DefaultMutableTreeNode ("deck"); DefaultMutableTreeNode Item Clubs = New DefaultMutableTreeNode ("Club"); AddAllCard (itemClubs); Root.add (itemClubs); DefaultMutableTreeNode item = New DefaultMutableTreeNode ("Diamonds"); AddAllCard (itemDiamonds); Root.add (itemDiamonds); DefaultMutableTreeNode Itemspads = New DefaultMutableTreeNode ("Spades"); AddAllCard (itemSpades); Root.add (itemSpades); DefaultMutableTreeNode item increases = new DefaultMutableTreeNode ("heart"); AddAllCard (itemHearts); Root.add (itemHearts); Default Trimodel Tree Model = New DefaultTreeModel (Route); Tree = new jetty (tree modal); ScrollPane = new JScrollPane (tree); // scrollPane.setViewportView (tree); .

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
