Game Programming :: Lines Not Depth Sorted

Sep 5, 2010

I am stuck on a problem with combining lines with solid geometry. Look at the pictures. The first is a look at the object from above and the second is the same object seen from below. The gridlines in the second picture should be in front of the object. The lines are drawn using linelist (one line, vertexformat=positioncolored, it is then translated and rotated in a loop) and the cube is drawn using trianglestrip (vertexformat=positionnormalcolored). It seems like lines are not depth tested. How do I manage to properly draw both grid and cube?

Game Programming :: Waving Lines - Beginning And End Points?

Jul 25, 2010

I am designing a game, in which you have to connect some lines, these lines are defined by the beginning and end points. I would like them to wave, yet always keeping the edges on the two points, also, when you connect 2 lines, I would like them to appear to be one continuous line, which contains the beginning, end, and the point of connection between the lines. To do this I've tried bezier curves, with a random point, always changing, but I noticed that bezier curves only works to 4 points, and the line does not always passes through the points themselves...

Game Programming :: Appear On A Random Location On Another Specified Larger Picture Box?

Jan 13, 2011

I have a picture box and I tell it to appear on a random location on another specified larger picture box.

here's my code:

Code:
Sub P2_AppleMove()
Dim P2ax As Integer = CInt(Int((P2Foodarea.Width * Rnd()))) ' sets the random area of the food

[Code]....

P2foodarea is a large picture box I created. I only want the apple to spawn on P2Foodarea, atm, it spawns on P1Foodarea which is very weird. P1foodarea is a whole other picture box. I even made new variables as you can see P2ax and P2ay, but it still doesn't spawn on P2Foodarea. I have even tried recreating a new picture box for P2foodarea

How do I go about doing this? I have currently made this code, but sometimes points are created on the boundaries of this picture box, which I do not want. I want all new random points to be within the bounds of this large playarea (picturebox). Foodarea is my big picturebox which i want all fruit to spawn WITHIN not outside on it's edges.

Number Guessing Game - Allows A User 10 Attempts To Guess A Random Number Between 1 And 50

Nov 9, 2009

I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.

My two (I am sure very basic) questions are:

1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.

2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?

vb.net Option Explicit OnOption Strict OnOption Infer Off Public Class frmMain Private Sub btnExit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExit.Click Me.Close() End Sub Private Sub txtGuess_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles

Selecting Random Number From ComboBox?

May 15, 2009

The problem I have is I have made a program which you select a value from a combobox and it changes the value of a url for a picturebox and thus changes the picture, I also have a button which randomizes all of the comboboxes so I will get something unique, but every time the program loads, and I hit random, it chooses the same numbers in order. If you need an example, when I press random the first time I get the number 7 for my first combobox, so the selected index=7, every time I load the program and press random it picks 7 for that combobox.

Game Programming :: Program Is Designed To Generate A Random Hand Of Cards Out Of Our List?

Aug 19, 2008

Below is the code that we have been working on. We have bolded the parts which we are unsure about - they are producing errors. (its near the bottom)The program is designed to generate a random hand of cards out of our list of them. This program is a smaller version of what we hope to have in the full one - ie. It tries to get a random hand of 3 cards out of a possible 5.

The part we are having errors with is getting the images to display on each of the 3 'picturebox' objects using a loop (so we don't have to type each picturebox individually).

TIP 1: Index Lines In Large Text File For Fast Random Access?

Jul 14, 2011

When you need to do random access to the lines of a text file, the regular solution is to put those lines in a list and access them in that list.But doing this if the text file is large creates a large memory overhead and may cause some memory stress on the application.This class maps the file and provide the ability to read any particular line in the file at a random position, without the need to read or put in memory any other line but the desired line. The only memory overhead involve is the 1024 bytes buffer of the base stream.Even if the file mapping can be a process that consume a noticable amount of time if the file is very large ( ~ 5 seconds for each 100,000,000 caracteres) , once the mapping is done the access to a particular line becomes instantaneous regardless of the size of the file. (The file mapping can always be done at a convenient time (ex when the process load) and can be done on a worker thread The class is base on a StreamReader to support the differents Text Encodings Example uf usage ( As I say, if the file is very large, dont do it like that, but declare the class at a convenient time)

Imports Reader = System.IO.MyStreams
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Game Programming :: Display In A Label The Appropriate Number Of Dashes?

Oct 12, 2004

I trying to display in a label the appropriate number of dashes based on the number of letters in a word that the first player entered.

Basically, when you click play, the first person enters a word, then the second player guesses what it is. That person has 2x #ofletters of incorrect tries. I just need to figure out how to get the dashes to display based on # of letters and not a preset one of 5 dashes. The original program accepts only 5-letter word so that line of code is Me.lblWord.Text = "-----". I have modified it so the user can enter any # of chars. I tried making the above line with a lot of dashes so it but the leftover dashes will stay there and the game won't end. Here is what i have right now for my play button:

Private Sub btnPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlay.Click

How To Count Number Of Lines In Text File

Dec 9, 2011

Basically, every time an entry is made - all of the proper data gets put out to a central Listings.txt file and then a specific .txt file for that area. When the user enters the recall form, they can view the listings for all or whichever area they've selected. That works quite fine. However! We also need to include a summary of how many are in each section. Not thinking properly, I started to do this with a counter - until I realized that a counter will lose its value once the program shuts down. My current idea is to count the number of lines in the text file (it outputs 8 lines per listing, so everything would be in values of 8) and then divide that by 8 - but after some searching I haven't been able to find a piece of code that will allow me to get an integer that relates to the amount of individual lines in the file.

Random Number Generator Game?

Mar 15, 2009

Stuck programming a random number generator game. one is to guess what the random number. I have coded most of it and am pleased, but there are some hitches. a) When running the program if you guess 10 it says," Guess Higher" which is impossible as the num gen stops at 10 (if you guess 9 and the number is lower than 9 it says guess lower . . . which it is supposed to do)

b) When asked to play again if one clicks no it calls you a loser and exits the problem is it does the same if you click yes. How can I get it to simply start over if yes is clicked

c) Does anyone know how to make an image move up or down based on the input? IE if guess needs to be higher the image moves higher? Lower and it moves lower?

Selecting A Random Button And Modifying Its Text?

Nov 13, 2009

I am making a game of tic tac toe, and I have 9 buttons lined up in a grid pattern. I want to select a random button for the computer to start the game from.

I have an array set up with all the names of my buttons, and I was thinking of picking a random entry from that array to start working from. This I have done fine, but I cannot change the text of a button. My code:

''# Define the array
random(0) = "tl"
random(1) = "tc"
random(2) = "tr"

[Code]....

as you can see, I can't simply do StartPoint.Text = "O", even thought StartPoint holds the name for the button.
