I'm making a game where the main character is a white blood cell. Right now I have a circle. 360 points. I want my character to squish against walls, jiggle while moving, etc... but I'm just at a loss as to how to even start doing this. What's the best way to implement that kind of 2-d physics?

View 1 RepliesI'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double()
Dim i, j As Long
Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.

View 1 RepliesThis is not a programming question but a physics one.I was wondering if anyone has a link that good give me the math for two objects: one moving and the other intercepting. Specifically, I need to determine the vectors of the pursuing object when given the vectors of the object he is trying to pursue.This is classic video game programming and in my instance it's supposed to be a football player running with the ball being chased by a tackler.The code I have now determines where the tackler should go at one particular instant, but does not project where he should be in order to lead the target.What happens is the tackler runs behind the ball carrier - he doesn't cut him off.It's like if a QB throws the ball to where his receiver is instead of in front of him; when the ball arrives the receiver is long gone.
View 2 RepliesI need some help calculating physics after a collision, sort of like rigid body physics but just for rectangles, I don't need them to rotate but only to know the x and y speed they leave each other and the angular velocity etc. the collision with the walls work fine since all I'm doing is reversing the speeds of the rectangles (which is probably the wrong way of doing it) but unfortunately this does not not work for the two rectangles colliding with each other, so can some1 lead me in the right direction as to how I can go about calculating this.

View 2 RepliesWhat I'm trying to do is simulate projectile motion in Visual Basic using Visual Studio. Essentially, something like this but without air resistance or mass.
Anyhow, the way I'm doing it is using a PictureBox and drawing the image in (of, say, a circle) every so often with a timer of interval 1 with its x and y properties being variables calculated by the formulas.
I want to know what formulas I can use to assign to x and y so that I get a movement like the one on the example. I've tried a bunch of stuff, with help from wikipedia and other sites, but can't seem to pull it off.

I have a project in WPF/VB.net 2010 that I want to create an alternate version of in Silverlight. However, it uses heavy amounts of animation, especially motion animation. Most of this animation takes advantage of storyboard double animations for either translate transforms or canvas left/top changes. Can I convert this project over to Silverlight?

Now i want to switch between the webcam if there is more than one webcam connected to the system. For example, the user of the system will be able to chose any webcam that is connected to the system. I am able to detect all the webcam and display those devices into a ListView. But i don't know how to change the steaming video when the user select the device. Now the video screen show the image form the default webcam.

I'm trying to make a way to navigate around a custom grid. Basically, I'm implementing the drag-copy feature from Excel. Right now, you click on a cell grid and can drag around the grid. Anything in the drag area gets a green tint. Once you release the mouse button, whatever was in the first cell selected is copied to all the others that are tinted. That works pretty nicely, but it works only for the cells visible on the screen. I can live with that, but decided that if you dragged over the scroll bars or the column or row headers,then the grid should scroll (if there is anywhere to scroll).
That's where the problem arose. It turns out that scrollbars don't raise the MouseMove event (at least not as far as I can see), and the MouseEnter and MouseHover events are not fired as long as the mouse button is held. Interestingly, the MouseLeave event does occur when the mouse button is held, just as the MouseMove event is occuring for all the cells. That's pretty annoying. Why do some mouse events get raised when the mouse button is down while the others don't? Also, I suppose, is there any way around this?
how to incorporate a PIC with VB.
I`m trying to find out the steps needed to achieve that, i`m i correct?
1) i need to find a PIC that is suitable for my project (to handle wireless motion sensors)?
2) I need to write the code for the PIC? (does the manufacture of the PIC provides an environment to write the assembly language?)
3) Then i need to write the vb code?
4) Finally to use a serial port to create a communication between VB and PIC. Also are their any all ready made PIC`s that can support VB code direct without the need of writing the assembly code?

I made a Vista Aero -style form for XP, but when using it, the application won't close. The FormClosed and Disposed events fire, but not the HandleDestroyed event. I tried to get around that by handling the Disposed event and calling Me.DestroyHandle(), and it worked, but not if the user resized the form so that it caused an IndexOutOfRangeException in BlurImage().The code is attached.

I am trying to compare two arrays that always have different dimensions.
e.g. arr1 -> {1,2,3} and arr2->{1,2}
I did try and able to get the matching items to new array. But I am expecting to get the unmatched items only. I am expecting to compare both arrays and put only the item '3' to a new array which is in arr1 and not in arr2
e.g. arr1 -> {1,2,3} and arr2->{1,2} should result a new array with 3
arr1 -> {1,2,3,4} and arr2->{1,2} should result a array with 3,4
