I am looking for some info to do some animation. Fairly simple stuff like dealing and flipping over playing cards, tumbling dice and such. I normally work with logic and data and do not know what would be the best approach to do a good looking animation like these. Does anyone know of some good sources on the net or even better some sample code to do this sort of thing or get me started.
View 14 Repliesi recently posted a thread about the same project, but decided this was a more specific question, so i decided to open a new thread My question regards the graphics class in visual basic 2008. Ive searched the internet low and high for an answer to this, but i cannot find anything! I am attempting to 'shoot' a circle drawn on the form when the user presses the 'r' key. if a string property is set to right, the graphic should be drawn, then updated to different x coordinates based on an interval. if the property is 'up' or 'down' then the y coordinate of the graphic should be changed based on another interval. Now i cannot use one preset timer, because i would be able to shoot only one bullet at a time, which would not work!
Does anyone know how i can either create an array of graphics(bullets) and add to the list every time the user presses r, then using one preset timer, update them all, or simple create a timer every time a bullet is created, then update the bullet position with its own timer.
I have multiple bitmaps(i) in arrays, and I want to know if I can save each of these bitmaps into on animated gif file. I thought about using image.saveadd() but i'm not sure if that will work.

how to correlate info from a textbox based on a listbox item selection. For example the user will select an item from the listbox, enter say the length of a song in the textbox say 2:00 for song #1, select say song #2, enter the song time for that song say 3:00, click on song #1 again and have the same textbox display the length of that song and be able to do that until there are no more songs on the list.
View 5 RepliesWe have a GIS application that has some performance issues. It creates and sends an image to a web browser. We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.
The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.
So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost? It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

ok, i know the code is a little rough, but it should be good to give you an idea of what im trying to do, if not i will still explain.simply draw 2 lines one from left to right, another from top to bottom, intersecting through the tip of the mouse.ok, theres no problem there the lines draw perfectally the way i want them.... BUT! now heres the issue im having.i cant get rid the previous lines.i did a bit of good old "Google'ing" and ran across a few links that all pointed me to the ReDrawWindow API, so i tried (as you can see in the above code) but i just cant seem to get it worked out.
So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.
Ok I have this: This makes a sub called 'graphicspaint' then writes "demo version" to a picturebox1
Code:

Imports System.Windows.Forms

View 15 RepliesMy application is all centered around one form with lots of graphics drawings on it.All these drawings take place from within a paint event handler. However, the amount of code within that sub is becomming unwieldy.I have been trying to move sonme of it to another class and use the "dim temp as Graphics = e.graphics" construction to continue to draw graphics. However, I get all kind of argument exception runtime arreors when doing so (and I do not get these with the same graphics operations directly from the original paint event handler. I have also tried to pass on the original e argument, but with the same result.Is my conclusion that there is no solution to this so to continue with the unwieldy amount of code,correct, or am I mistaken somewhere. the "dim temp as graphics = e graphics" is recommended.

View 10 RepliesIn a Previous Thread, I asked some questions about how to create graphics. Everything was OK, until I realized that the graphics are really slow. While I was trying to find out what the problem was, I realized that the processor load was about 50% and my graphics card was not used at all. So doesn't Visual Basic use the Graphics Accelerator to process graphics? What I made is not a real program. It's like an experiment (I tried to make an image flip). Here is the Code:

(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.
