Tile Game: Converting Pixels To X/y Coords
May 5, 2009
So now I'm working on the map editor for my game. The map itself displays 32x32 pixels out from the upper and left bounds of the form. Each tile is also 32x32. So then i have two labels which display the corresponding coordinates divided by 32, this way it would show you x: 7, Y: 8, or whatever. The issue is that the map will be like 15x10, and when moving the mouse to the 15th row/column, it shows 15, but then moving to the 14th row, still shows 15. The rest of it works fine. Here is the code.
Private Sub FrmDesign_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
If e.X < (subZone.Width * 32) + 32 And e.X > ((subZone.Width * 32) -

Essentially I have a half text/half graphical tile game that has a level designer. I have several sets of tiles, all of which are bunched together in one file. I'd like to read a certain 32x32 square of said bitmap, and display only that portion on specified area of the screen. I know GDI+ enough to get the display going, so I just need help with reading the specified portion of the image from the bitmap.

I'm trying ot make a top down rpg, or pokemon like game, but I can't find any proper tutorials for collision detection. I have found one, but when I did it it doesn't seem to work properly, and I get errors everytime I go to the edge of the form. What I can do to make good collision detection for walls?
HTML Code:
Public Class Form1
Public Level1 As New clsLevel()
Public Dude As New clsSprite(Level1)
Dim CanWalk As Boolean = True
[Code] ......

I have a very basic tiling engine that was made from a YouTube tutorial for making an top down RPG style game and I am trying to adapt it to a platformer game. The code is fairly simple but not being a physics guy I am looking for adding a Mario style jump to the program. I know there will most likely need to be some additional variables added to it such as gravity and velocity. That said I am not sure where to get started, below is the meet and potatoes so to speak of the program.
Code:
' VIEW PORT
Dim ResWidth As Integer = 750
Dim ResHeight As Integer = 550
Dim TileSize As Integer = 32
' GRAPHICS VARIABLES

I have a question about collision, yes my 2d tile rpg's map collision works just fine, but im having trouble with the collision with my npc's. At the start of the game it loads all the map data from a text file. well it also loads the location and other stuff about the npc's onto the map from a text file. how do i detect the collision of the npc's that were loaded from the text file, i could do collision with hardcoded npc's but i want to avoid hardcoding the game content into the game engine. RESTATING MY QUESTION: How do i detect the collision of NPC's that i load onto my 2d tile map from text file?

Is there a way of converting pixels to points? The dimensions in VB are in pixels, but Office COM such as WordApp.Resize are expressed in points. So trying to align app windows is a mess.I guess the ratio of pixels to points varies from one monitor to another(?), so this would need to be calculated at run time.I tried a nifty trick of doing Me.Font.SizeInPoints / Me.FontHeight but that doesnt seem to be quite right or a very sensible way of doing it.

I'm trying to make a -what i thought would be simple app.My intention was to build program that:1) i'd provide a grayscale image2) the program would count the black pixels the grey pixels the more grey pixels etc. (the hue) and the white3) would make the percentage sum of all pixels, that is: 300.000 black pixels (rgb 0 0 0) etc. given that 0 is the black, 100 the white. e.g a simple grayscale image is 55.2 white
This was my way and i don't think that is useful:
First of a button to convert the image to greyscale:
Dim bm as new Bitmap(source.Width,source.Height)
Dim x
Dim y
[CODE]...
Secondly, -and that's the stupid way- i did -or better i wanted to do- this: i put the code to dynamically create labels, each label having the colour of a pixel as background colour and as text the colour converted to rgb
The third step which i intended to do (i couldn't get pas two) was to sum up the labels etc.

I'm working on a project for personal use. I have a web Cam where I took out the lens and replaced it with Blue and Red Cellophane, to filter out light.
The web cam is fed into VB and an infrared (IR) light is shined into the web cam from different positions.
This produces a Black image with a bright white dot moving around.I would like to know if there is a way to get the Dots coordinates (or any other way to measure relative movement from the first dot).[code...]
Would it be viable to take snapshot of webcam's video and search with this engine? (I assume testing is the only way which I am about to try...)

I want to show a ContextMenuStrip beneath a MenuStrip item when that item is clicked. Stuff in the ContextMenuStrip changes dynamically. The ContextMenuStrip is used in a DataGridView. I don't want to duplicate the same items in the MenuStrip.
I can get the mouse coordinates OK, but I don't want that. I want to use the ContextMenuStrip show method referenced to a control. An item in the MenuStrip is not a control, but the entire MenuStrip is a control. If I can get the x-y position of the item in the MenuStrip I can show the ContextMenuStrip in the right place, and it will look just as if it was part of the MenuStrip. how to obtain the location of the MenuStrip item that's active.

I am working with a PictureBox and trying to click on the picture and OnClick i want to capture XY coord from the cursor.
I am using the following code
Private Sub PictureBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseClick
Dim X As Long
[Code]....
The issue i have is that no matter where i click on the picturebox it returns a 0 for both the X and Y coordinates.
I read something somewhere about seting the Scale to Pixel but that doesnt seem to be working for me.

Basically I want to move my mouse to the coords that is received based on the location of a certain coloured pixel. I can get the coords of the pixel but when using them on mouse position, the mouse position is based on the entire screen rather than the form. How could I change the position coords based on the form rather than the entire screen. E.G. If a certain coloured pixel is 2,2 in a form and I put that as the mouse position, it would go outside the form but I dont want that. I want it to hover of the pixel coords
This is my
Dim bmp As Bitmap = DirectCast(PictureBox1.Image, Bitmap)
For x As Integer = 0 To bmp.Width - 1
For y As Integer = 0 To bmp.Height - 1
If bmp.GetPixel(x, y) = (Color.FromArgb(108, 90, 60)) Then
Windows.Forms.Cursor.Position =
End If
Next

(non-coding request)Okay, I have my client, my server, and my map editor...a 2d online game, and yes it's written in VB.NET.I have had a lot of trouble finding anything to do with adding an animation layer something that will flash with a timer to appear as if something like fire is animated. I have a lot done so far and I kinda want to stick with VB.NET working with this.
I'm not really looking for code here, but maybe an idea of "how" an animation layer plays into a map editor and client...specifically what is needed.Running this through my head I believe I am going to need a timer on both the map editor and client, showing and hiding the animation layer...but I don't think it is that easy, and am hoping someone here has an idea of the logic of how this works. I'm almost certain that the timer doesn't go on the server to control this, but am probably wrong.

I've managed to implement a formula that helps me to get the closest tile's distance that meets my requirements. The only thing is, I can't retrieve the actual tile for some reason... Tiles are named "Items" also. Here is my code:

It puts green squiggly lines under ClosestItem and gives me the error: "Warning 2 Variable 'ClosestItem' is used before it has been assigned a value. A null reference exception could result at runtime."

I have a picturebox and I have a image with a blue and red square. When I click a button it puts that image into the picturebox as background image. The background image property is set to tile. But when I click on my form to draw the image to it, it just draws the original not the one that has the tile effect from the picturebox. Is there a way i can do this to keep the tile effect?

I have a program which contains a mdi form and child forms. Due to some reason the mdi form layout functionality does not work if a form is hidden and shown. This is a bug in the UI control suit which I am using.
I would like to implement Cascade,Tile horizontal & vertical myself. I wrote the logic for cascade but can I get code or function for the other two.
Would be glad if anyone can give me code/logic/function so that I can do Tile horizontal & Tile vertical manually.

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.

So now I will try to make something more complex, still playing around with this graphics thing.I want a picturebox to display a tileset (a bunch of 32x32 tiles normally used for creating game levels etc), the picturebox is inside a container (which has autoscroll ON). The picturebox is larger than the container, so the container will make scrollbars automatically.Now, I need to be able to choose a tile or multiple tiles (if I click & drag the mouse)Basically I want to draw a 32x32 "red" box over each selected tile (so the user knows what tiles are selected).So first of all, I need to know when the mouse clicks the picture. Good. It works.Now, I need to know which 32x32 tile was clicked. Well, I think I can calculate that just fine.BUT, what if the user drags the mouse while clicking on a tile? I want to support multiple tiles selected, but I am clueless about tracking what tiles were chosen.If we solve that problem, I would have another curiosity: You know the "red boxes" that tell you which tiles are selected? What would happen if I dragged the scroll bar? I need the redboxes to move along with the picture, and hide if they go to an invisible area.
