View 1 Repliesis there a way to offset the points in a polygon without having to change each one individually the points are in an array
View 2 Replieshow can i calculate the 13 points on the polygon (see image)?
the 2 points either side of the centre points
are +/- width or height * 0.2761423749154
i have 4 known points, topLeft, topRight, bottomRight, + bottomLeft.
the polygon won't always be a regular rectangle as it is in the image
I'm making a game for a school project We've created a character that moves around the screen and creates blocks behind him as he moves around.We want to make it so that when the character moves from one edge of the screen to another, it fills the screen. So in order to do this we have a Points array that stores every point the character touches on his way to a wall.We then fill the Points array with "formsurface.fillPolygon(Points)"Now I'm wondering is there anyway we can retrieve all the points that are WITHIN or INSIDE the Points array we made? ( remember the points array simply contains the outline or the path the character created, we're filling inside that outline)

View 2 RepliesI just finished creating a program where you find the area of a 5 sided polygon. But not I want to actually draw the polygon given the coordinates
Private Sub PI_Estimation_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
Dim myGraphics As Graphics

I have a collection of latitudes and longitudes and I'll be grabbing sets of these and want to draw a polygon based on them.The datasets won't be the outline so will need an algorithm to establish which ones make up the outline of a polygon containing all the latitudes and longitudes supplied. This polygon needs to be flexible so the polygon can be concave if the points dictate that.
My code below produces a horrible looking polygon. As explain in my first post I want to create a nice concave or convex polygon based on the latlng's provided.Just need a way of plotting the outer latlngs.
function initialize() {
var myLatLng = new google.maps.LatLng(51.407431, -0.727142);
var myOptions = {

i dont know how to do this.i need to create a macro to use on microsoft excel to calculate the area of any polygon. my problem is similar to this one: [URL]..but de vb code is not working for me.in attach i send the excel page.i also have to calculate the coordenates of the "center of mass", Cx and Cy using diferents functions.
View 1 RepliesHow do I make a label add points?In other words I have a label with the text of "0" If I click a certain button I want the label to become "1" displaying that as the amount of points.If I click another button that gives 2 points I would want the label to change to "3".Get it? Hope I was clear.
If TextBox1.Text = "Blah Blah Blah" Then
TextBox1.Text = "Generate a New Code - Points + 2"
Label2.Text = +2
End If
On click, I'd like this piece of code to create new polygon, shown in multiples with different coordinates and colors, sizes and orientation. Color and polygon in multiples works. My issue is I'd like to add more code that will allow each of the multiple polygon created scaled randomly and rotated. How to keep the polygons inside the canvas?
So far looks like this when user clicks start: [URL]
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles startButton.Click
Dim endCount As Integer = random.Next(1, 10)
Dim plotPoint As New Point
For count = 1 To endCount

I'm working on a small freeware application in Visual Studio 2008 Standard that will match geographic data to a geographic position. For this I need some mathemathical functions and one of them is how to detect if a point is inside a polygon. There's a great solution for this from the Microsoft team at: [URL]
but it is in a different programming language that I do not know anything about. How can I use these functions in my program? I'm afraid that if I try to rewrite them in Visual Basic I'll make mistakes that I can't detect. To be complete, I'm not using screen graphics so I really need a mathemathical solution.
I want someone to help me on using graphics on vb.net form.I am planing to make a clock so first i want to draw 12 points in a circular fashion.
View 3 RepliesI'm trying to write a simple game ui, it is grid/tile based, and i have the grid built using grid column and row definitions and I'm successfully placing objects in various grid locations. I am currently stuck as trying to build the player object. I want a single object reference to represent the various components of the players piece.
Currently I am using a polygon to represent the piece on the grid. Eventually I want to replace this with images or something. I want to add in properties for what weapon and armor it has equipped I want properties for health
Essentially in code i want something like this
dim player1 as new playerobject
player1.polygon.points = 0,0 60,30 0,60
player1.health = 100
[Code]....
I can instantiate all this as separate variables etc, but I'd like to have a singular reference that contains all the variables, properties, objects, controls etc.
I'm using vb .net in vs 2010 (and no, I'm not looking to write in something else)

look at this picture of my index form. It's resized, now you can't see the full labels text.
Example: under the first cover, there stands "Hardbass Chapter" and accetly it is "Hardbass Chapter
21 (2011)". It's not a problem that a peace cut off, but, I want to make that clear to the users,
with adding some points.
I would like to make a Settings Field (SKey) to point to a constant (Q)
Where the Settings Value will be modified by the user using Text box and public const Q = keys.Q so I can let the user modify a hotkey to what ever he wants I wished to use the following code for registering the Hotkey
Public Const Q = Keys.Q 'My.Settings.SKey should points to this variable
'There will be more constants for other keys
RegisterHotKey(Me.Handle, 1, HCtrl + HAlt, My.Settings.SKey)
the problem is:
the program use MY.settings.SKey as String and I cannot define it as integer where the input is a text
I've created a polygon shape and filled which fills blue on startup.Upon toggling a check box it should be filled yellow.It doesn't go yellow (unless i step through in debugging).
[Code]...
I am writing a program wherein the user draws shapes by clicking a button for the desired shape and then clicking on points on the drawing area. I cannot figure out how to store four clicked points to create a foursided polygon. I read many articles that say use the "mousedown" command and store points in a list, I have tried but it's not working for me. To summarize, I need the user to click the polygon button, go to the drawing area, click four points and have a foursided polygon created.

View 4 RepliesI've come across a very basic problem which I'm sure has a basic answer.Forgive me but I haven't programmed in years and this just a hobby of mine..My problem is that I need a drawn object (say an ellipse) to move to the cursors location when I click. Imagine an adventure quest style game where you view your character in birds eye view, and it moves according to where you click on the map.I can draw the image fine, and move the image around fine - it's more so the formula I'm using which I'm a little stumped on.I have certain requirements though.
1. I need a timer that constantly updates the drawn object's (lets say character from now on) location. Each tick will essentially be the character taking 1 step towards the cursor's location.2. At the end of each tick of the timer, it'll will invalidate the form/control to invoke the paint event, and of course, the objects location will be be updated.It sounded simple enough to create a linear equation based on the objects original location and the location of the cursor when I click.However, that will not give it a fixed speed.If say for example, the gradient (rise/run) between the cursor location and objects location is very steep, the object's y-velocity will be greater than that of the x-velocity
I am developing the map tool application in vb.net where user can create maps. I gave the check boxes for show/hide the layers of map like village boundary(polygon), plot boundary(Polygon), roads(Lines), bore wells(points), dug wells(points), schools(points).
I am using the function RedrawMap for displaying various layers of maps as user checked the check boxes. If user click village boundary map shows the village boundary etc on panel control named "picMap".
The problem i am facing is when user check the village boundary layer map shows the boundary but when user check the next polygon layer i.e. plot boundary layer it gives the error message "5:Object is currently in use elsewhere.".
My code is as follows:
Public Sub RedrawMap(ByVal index As Integer)
Dim f As Font
'Object Style
Dim Size1 As Short

I want to find out the X and Y position of a point which is halfway between a point and another point, in VB.net. Since there is no "direction" property (which would make this much easier...), I have no idea how to do this.
C# code is acceptable as well, though I would prefer vb as it wouldn't require a port.
i have this code in vb and i want to know how to make it to add decimal points
Dim a, b As Integer
a = CSng(TextBox1.Text)
b = CSng(TextBox2.Text)
