Creating A Space Invaders Game That Has A Group Of "invaders" Moving Side To Side?
Dec 2, 2009
Im creating a space invaders game that has a group of "invaders" moving side to side and when i shoot one it gets destroyed, my invaders are in an array. So in order for the invaders to keep moving right until they get to the edge, i made a function that detects which invader is right most. But this was crudly done as I wa trying to make the opposite of my left most function which works. So my rightmost function dosent work
i'm not very familiar with GDI+, but i managed to create some basic functions of Space Invaders game i try to develop in Compact Framework. I have problems drawing the images (Spaceship, bullets, enemies). The screen is flashing a lot. I use a buffer bitmap in which i draw images to the new positions, and i have 1 line of code that just draws the buffer to screen
[Code]...
i use me.Invalidate inside a timer so every 50msec the game redraw the screen with new positions. Why the buffering does not work?? It can't be the emulator that i preview the program, it is flashing A LOT. Is there any similar code / project that could help me? i'm tring to find a similar project for COMPACT FRAMEWORK but i only find C++ .net examples. i need VB .NET COMPACT FRAMEWORK examples
I'm trying to make a space invaders rip off, and I'm currently stuck on how to make the missile fire from the center of the player's ship. I have the missiles all in a control array, and they move up the screen fine, they just dont start at the x point of the ship, they start on the left margin.
Dim Line As Integer
If Missile(0).Location.Y < 391 Then
Missile(0).Location = New System.Drawing.Point(Line, Missile(0).Location.Y - 5)
I've got everything working except this one problem which I can't seem to get my head around.I've made a function that returns a random number between 1 and 11 (how many invaders there are on a row).I've managed to get this to work, however the invaders will keep firing even if they are visible, so I made a do until loop which says to keep running the random number until it finds an invader which is visible... The problem is that if the whole row of invaders aren't visible, it will get stuck in the loop.
I want to make a simple 2d game in Silverlight, but it seems like things have changed since the last time I tried to make a game using mode 13h graphics. Can someone give me a run-down of how you'd go about it.I just mean at a high-level, focusing on the silverlight-specific aspects; not general game design.A fictional example might be:'The main game loop shouldn't be a loop, use a DispatchTimer instead. Use a Canvas as the main drawing object; but realize that we don't bother drawing individual pixels - all of your in-game objects should be represented by controls. Be sure to set the 'UseHardwareFlag' to true'.
Been given an assignment to create a space invaders game. Although there's a long way around, is there a way to make my code smarter.Here's the section to make a row of invaders so far:
Public Class Form1 'number of invaders in a row (horizontal) Dim numberofinvaders As Integer = 11 'set of invaders (vertical)
[code]....
So what I want to do more precisely is have the value of setofinvaders to change how many rows of invaders vertically in a loop.
i am currently trying to make an invaders-like game with visual basic 2010.I've managed to make one alien (picturebox16) dissapear when the coordinates of the arrow (picturebox1) kinda matches the coordinates of the 16th alien, however, the second alien(above it) doesnt dissapear(picturebox4)?
I am starting a butterfly program and having an issue and really just barely have it started and would like to get some helpfeedback on how to do this. The following is the instructions and I will make a second post on what code I have so far...The butterfly is going to be moving from side to side in a slightly upward assent when the animation starts. You need to build a set of controls that allow the user to control whether the butterfly ascends (up) or descends (down) and also allows the direction of the butterfly to change (left or right). The best way to implement this feature is through the use of keystrokes that when pressed act to control the direction of the butterfly. Whether you implement this feature through keystrokes or controls, make sure that the feature is communicated to the user.
Butterflies fly by opening and closing their wings. So it is expected that the butterfly will alternate between opened and closed as it wings its way across the form. If the butterfly is moving right, make certain the butterfly graphic displayed shows the butterfly as moving toward the right. If the butterfly is moving to the left, make certain the butterfly graphic displayed shows the butterfly as moving toward the left.
If the butterfly reaches the top of the form in its assent, it should wrap around to the bottom of the form. If the butterfly reaches the bottom of the form in its descent, it should wrap around to the top of the form. If the butterfly reaches the left edge of the form, it should begin flying toward the right side of the form. If the butterfly reaches the right edge of the form, it should begin flying toward the left side of the form. If the user changes the direction of the butterfly, insure that the correct graphics are used in relation to the direction of the butterfly and that the butterfly moves in the indicated direction. Please note that when the butterfly reaches the edge of the form, the butterfly must change direction regardless of any user input.
What I mean by "Checking ".left" of whole object" is making something happen if, for instance, a label were to hit an object. Instead of it needing to hit at the objects exact left, it could hit anywhere on the object. Bit confusing...I know...here is an example...
I know this defeats the purpose of client side vs. server side (refer to title of this thread). What I would love to do is build my own custom progress indicator on the client showing how far a server side code has progressed. I figure if I could only get a JavaScript to fire and render a value of some control at pre-defined intervals while the server is working I could make it happen - but alas I'm beginning to believe that this is impossible. Below is some code that performs three 2 sec loops. At the end of each I want to change the visible value of a control on the browser. [Code]
I have a basic asp.net web page. I have a menu bar divided into 3 columns. Each column displays an xml file. However instead of showing them side by side it displays them one on top of each other. i think it might be to do with my css?
My asp.net web code: <div class="menubar"> <div class="menuleft">
I need to send back the id, the old value from _1 and the new value from _0 back to the server. What is the best way to format this data so I can easily extract the data from the server side so I can easily email someone for example to let them know which textboxes have changed, what the old values were, and what the new values are
At the serverside level, I am using .NET-3.5 (VB). I know how to send the data bacl. and how to email the data, I just wanted to know how to best format the data at clientside before sending it back. I could have upto 50 sets of id, old, and new values to send back. Sorry for not making that clear earlier.
Example:
How can I modify the script above to generate this?
I'm working on a 2d game. making a button that can move in a path random up,down, side -side, etc. in a selected space. and once hits end of the form to slide out and reappear at other side of the selected space and do same thing over.
I currently have a parent Listview and its child Listview displaying in the centre column of an HTML page that consists of three columns left, centre and right. And all looks very good. However I would like to display the child list view in the right column beside the parent list view.
To do this it seems I must somehow generate from the code behind page a new row in the table every time the parent Listview displays a record of its data and then some column HTML so the first child list view will appear in the right hand column.
I'm trying to, from a client-side piece, call off to a server-side piece. I need to do this synchronously. On my server-side code, though, I'm calling off to another piece of code, which I want to have a maximum of, say, 10 seconds to return a value. If I don't have a response within 10 seconds, I want to force my own server piece to set my result equal to 0, and return to the client.
Here's what I have on my server-side code so far:
Public Function GetWebResult(ByVal inputParameter As Object) As WebReturnObject Implements IWebInterface.GetWebResult Dim result As New WebReturnObject Dim webItem As WebItem = Nothing
[CODE]...
I realize this code is not functional. The problem is that I'm unsure how I would go about getting back into GetWebResult to set the appropriate return values before it is sent back to the client.
I am struckup with a problem from last two days. I am creating a web application using VB.NET, Ajax & RAD Controls. When user clicks on a button I want to open a RAD Window and show the list of ledgers available to the user, so that he can select one from the list. And to open that window I have to call a java script function from client side, which is already achieved using the below code.
I have an application which have multiple tab pages. On of these pages I have a group box with many controls that do something.Now the problem is I want to add exactly the same group box by the current one that can have different paparemeters.This is exactly the way that i want to add comparison capability between to set of parameters.I have more than 500 lines of code that responde to changes of these parameters and does something.Is there any way to replicate the the whole gropbox and use the same code for both and and being able to difrentiate between gropboxes.I think there was an array control in vb 6 but I am not sure if this the best way to do this in vb.net.What is the best way to do this for the least amount of changing the code and wasting time.
I have form 1 and form 2 form 1 is already loaded. When i load form 2 i want it to apprear right next to form 1 on the right hand side. What code should i use to accomplish this.
Basicly I have a program that retrieves data and parses it, which is fine, so it starts from:11:981.8 which equals to November 981.8 now what I have done is split the "November" and the "981.8" into 2 different arrays, with other similar data, now what I need to be able to do, is sort the array in either Ascending or Descending order, however keeping in tact, the November and 981.8 side by side in a list box.
My current code is:
Private Sub sortData(ByVal strYear As String, ByVal strSort As String) lbDispData.Items.Clear() Dim strData As String = My.Settings.usage2011 Dim arrRawData() As String
[Code]...
EDIT: Just to mention, there are many more values, not just November and 981.8, there would be for example December and 128.1, January and 191.1, etc.
i am currently making a maths game but i have run in to trouble trying to do the addition and subtraction side of the game. This is my current class file for my multiplication
Public Class Class2 Private Property question_gameplay_label As String Private Property correctAnswer As Integer
Ultimately, what I want to accomplish is an AJAX-based messaging system. I already have a database table for messages, and an ASPX to add new messages (and declare old messages no longer relevant).
The current messaging system simply polls the server every 15 seconds, and re-pulls the current message set.
What I am looking to do is: On $(document).ready(), register an ajax callback function that listens for a server-side event (e.g., MessagesUpdated) On table insert/update, fire MessagesUpdated server-side.
This way, whenever the table is updated (or new records added), any clients listening know that new data is available and can re-poll the server then.
Ideally, I'd also like to make the new data available as an event argument (to minimize re-polling the db).
I can find references to something like this in other languages, but I cannot find any actual code examples to get me started.
Assuming this is possible to do via .Net, can anyone help get me started on this?
I'm using the 2.0 Framework. Also while I added a VB.Net tag, I can read C# reasonably well, so please feel free to post in either language.
I am creating my menu with javascript. How possible it is that on page load it is created from the server side (VB ASP.NET) rather than the client side? And if this is possible how is this done? My main aim is that I can create menu items from a database.
I have a website. In it, I have a button which will export some data from a SQL database to Excel. I want to open an excel workbook on the client and paste the data there. This all works fine locally, but when i publish it, I get this error:ActiveX component can't create object.[code]Have searched the net, and it seems the problem is permission related. Can anyone explain to me how to configure my server so that I can use clientside Excel?
Im recreating mario a side scroller game for college. im tryin to make mario jump through the use of a timer i want to be able to still move direction when jumping. so basically when i hit space bar i want point y to - 1 until it gets to 12 and then for it to go back down again. i havnt even got this far yet as when i was testin this theory the timer freezes if the arrows are held in. at the moment im only getting the timer to beep once it has reached 10.
I'm trying to create a small game in VB2010. The gameplay is as follows:
civilians would walk/stand in a room/street and suddenly an evil character would pop from the ground/wall. This evil character would suddenly vanishes too. So, the player has to shoot it to kill the character. The evil character, civilians, etc. would be random. Also, there would be sound effects too. That is the popping up of the evil character, it's voice, the civilians voice, etc. I'm trying to make it as simple as possible but without degrading the quality of the game play. I think, I could somewhat create the graphics for the characters, scenes, etc. and can get the sound effects recorded.
So, the difficult part is,[ ] how could I make it a smoother for playing the game ? [ ] what would be the best way to do animations ? [ ] Creating a GIF and placing it in the picturebox and moving it ? [x]how to play the music in background and at the same time play sound effects on certain instance ?
