Calling Offscreen Tiles In An Isometric Engine?
Jan 13, 2010
For a university term project, I'm working on a graphical roguelike (I'm aware of the contradiction in terms :P) that uses an isometric display. What I'm trying to figure out is, since drawing all the tiles is stupidly expensive and unnecessary, I'm wanting to figure out a relatively fast algorithm to determine which tiles should be drawn to fit within an NxMpx window, given that the tile graphics are XxYpx.
I'm not doing smooth scrolling for this, so that's not an issue. I'm also not worried about being perfect - a little unnecessary draw is fine, I just don't want to draw a huge amount of unnecessary tiles that won't show up in-game.

I've been trying for a week now to get a clipped tile from a sheet and draw it in either it's destination picturebox or draw it to a picturebox that will be the same size and the clipped tile and then draw it from there to it's destination. Nothing seems to work for me. I even tried using Bitblt but that didn't go very far, although I had better luck with that then the built in graphics functions. So, for now, I removed all code and decided to start from scratch again.
The only thing I got so far is this:
Dim myImage As Bitmap = New Bitmap("C:UsersSomeClownDesktopBitblitTestinasis.bmp", True
picSource.Image = myImage
As you know, all this does is load a bitmap file into memory and the second line draws the bitmap to a picturebox.

While trying to find an answer to my question, I came across a project called OTSe, which allows people to make they're own online 2d online games. The system is based on an open X, Y, Z square tile map. For the sake of easy understanding, lets say they're are 3 types of tiles. Tiles you CANNOT walk on, tiles you CAN walk on, and tiles that SLOW YOU'RE CHARACTER DOWN.The project team has created a API class for users to work with in order to develop tools. What I'm trying to do, using they're classes, is GET the all the tiles on the current floor I am walking on, and then display them in a tile grid on my form, changing they're color depending on what type of tile they are. If the tile is NOT WALKABLE, make the tile gray, if the tile IS WALKABLE, make the tile brown, and if the tile SLOWS YOU DOWN, make the tile red. I also need it to store the information of each tile, since tiles are objects, and have properties.

Remember MS Paint? The bucket tool? If you used it and clicked on a pixel, all pixels connected to this pixel that are the same are affected. The theory is, I suppose, to check if there is any pixel adjacent to the selected one. If such pixel is the same type as the selected one, check for more adjacent pixels in this one, and so on.
I want to implement something similar in VB.NET. Basically I have a 2D array map which represents the map. Let's assume there are only two types of tile: 0 and 1.Now, I got pretty much everything ready: I got my 2d map and I can tell which tile is clicked and tell what array indexes are the ones that represent such tile.Now for the "painting" process. Whenever I think about it, I can't figure a convenient way to execute such iteration. Can someone help me choosing a correct design/way/tip to achieve this?

I know VB.NET, and I've been planning on creating a simple 2d game engine. I got no problems with creating such engine and running the actual game. However, I've been told that VB.NET might not be the best choice for "working too much with graphics". I'd like to know if that's true. Can VB.NET truly not manage efficiently loads of graphics simultaneously on the screen? If no, what kind of software am I supposed to use for creating this engine?

I have a search engine that is supposed to search through descriptions of products and then will display something with a list of products that have whichever word(s) or phrase the user was looking for. I haven't made any kind of list for the products that use the description though.
I just need to figure out why my SELECT statement isn't doing anything. It's either that or the For Each loop.
This is what I have:
Public Function GetDescriptions(ByVal prefixText As String, ByVal count As Integer) As String()

I need to choose a database engine for a project, and have run into some issues. What I want is an SQL engine that works in a server/client environment, where i also can backup the database files from disk. If I am not mistaken, i have to detach an MSSQL database to be able to copy it in the file system. And SQLite is no good for the server/client environment. Will MySQL accomplish this? I think PostGreSQL has the same issue as MSSQL, but I don't know about MySQL.Oh, and it needs to be free to publish with my application.

I am developing a software that connects to a database and manipulates product and user data. It works on my computer but it will have to be used by many computers maybe even world wide (who will access the same database) so I have no idea what kind of systems people will have. I still don't know how to ensure that they will be able to connect to the database for I have already had problems in Windows 7 computers which don't have jet oledb.4.0
I am a bit lost here because I don't know if I should first try to do a connect, or if I should first look for a jet oledb engine on the computer where the software is installed. And in case they don't have it installed should I prompt them to install it before running the program further? Or should I pack the engine along with my program? What is the line of thought here to make the program run on (almost) any machine?

I was wondering about what approach to take for writing a state machine or data crunching engine.As such, it wouldn't have any UI component. Since it must be able to talk to other GUI programs, should it be hosted in a DLL? I noticed that there were some State Machine templates for VB but I have no idea how to use them. If

I just downloaded the MVC 3.0 RC and I'm excited to start using it, especially the Razor view engine. However, due to a few stick in the mud type people here, we are stuck using VB.NET instead of C#.When I started trying it out, I noticed some quirks. If you are creating a Razor view using CSHTML, you can write code like this:
@foreach(string genreName in Model.Genres)
{
<li>@genreName</li>
}
Razor will automatically detect that the <li> text is an HTML tag and will switch out of "code mode". With a VB.NET VBHTML file, this doesn't seem to be working. It's making me put the @: keyword in front of each line like this:
@For Each genreName As String In Model.Genres
@:<li>@genreName</li>
Next
If I don't have it there, I get a runtime error. Also, the <text></text> tags don't seem to work.

i'm working on a application whereby there is a keyboard which is create on FLASH. So i implement it into vb.net. So everytime i click on 'A', it will go into the database and search for all the stuff that contain 'A' and display on the flash textbox. If i type 'An', i will appear all the stuff in a Flash textbox. Just like yahoo, when you type 'An' there will have a downdrop appearing all the words that starts, end or inbetween have 'An'.

I am trying to create a VB.Net form that recognizes speech. When I run it, I get the error "Speech recognition is not available on this system. SAP and Speech Recognition engines cannot be found." So, following Microsoft's instructions, I discover that there is no Speech tab in Speech Properties (which appear when I click on Speech in the control panel). I am using Windows XP Professional. Only a Text-to-Speech tab, no speech recognition tab. To install the speech engine, I went to Add or Remove Programs/ Change Microsoft Office Enterprise 2007/ Add or Remove Features. However there is no "Alternative User Input" as per the instructions. How can I get this speech recognition engine installed?[code]...

I have a system on my webbrowser that allows the user to choose their Search Engine out of a selection I organized. the down point is that I have it set so when they click save it will just hide, because if it closes the settings will be reset and not saved. However I want them to save. Here are my codes to the search button:
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
If SearchEngines.RadioButton1.Checked Then
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate("http:www.google.com/search?hl=en&q=" & SearchBar.Text & "&btnG=Google+Search&meta=")
[code]....
This is the code of save:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Hide()
End Sub
I would like it so it saves when the whole program is closed, so when they start up it's automatically set so they can search on their favourite search engine.
