Brick Breaker Collision And Drawing?
Jul 23, 2011
I'm writing a brick breaker game. And I've come across a problem when drawing the bricks and detecting the colliaion between the bricks and the ball. I can't think of any way to draw multiple bricks, without testing for a ridiculous number of collisions.I have a class for bricks, with properties such as visible, loccation, and the bounds, but i'm not sure that this is the right approach.I also want to have different levels in my game so I have a class for levels.

draw individual pixels, without resorting to drawing a line and setting it's length to 1. Is there an actual ability to draw a pixel that is just 1 pixel big?

I need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False
[Code]....

What is the best way for collision detection? I keep trying but I have failed every time.I want my player to not be able to go through my pictureboxes/obstacles from ALL sides.I have 2 player movement down but now I need collision detection. I am trying to save player2's location with a timer using a variable for the location then check if player2 (picturebox2) intersects with picturebox3. If it does then picturebox2 will go back to the location.

I need help with collision detection in visual basic. I am trying to detect when a picture box hits another picture box. The code I'm using is very simple because I'm very much a beginner.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If Math.Abs(PictureBox2.Left - PictureBox1.Right) And Math.Abs(PictureBox2.Top - PictureBox1.Bottom) Then
MessageBox.Show("You Are Dead")
End If
End Sub

Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point. Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:

I am trying to do simple collision detection in VB.NET using picture boxes, I have a fixed picturebox, (colour Green), and a moving picturebox, (colour Red). I can manage the collision detection OK, but how do make the movingpicture box bounce off the fixed picturebox and at the right angle? In the following code the moving picturebox sometimes passes right through the fixed one, but not everytime.

I'm building a maze application in visual basic. The game relies on two variables, X and Y which are integers. There's a timer which basically invalidates the whole form for a redraw. Now my question is, that there are various squares and rectangles dotted around the form. How would I create a handler, or something as such to detect if the square that the form draws is touching these objects?[code]...

How To Have A Collision In VB.net XNA Using VB.net Codes And Format. Doing Collision In Normal Windows Form Application Is Simple By Calling Two Picture Box. Example:
If(enemyRectangle.Intersects(p�layerRectangle)) Then
'Do code here
end if
But In XNA VB.net, There Are No Multiple Picture Box Or Windows Forms Thingy Buy Only One Picture Box Which Contains All Sprite Block And Display.
Here Is The Class Content Code:
Public Class clsContent
Public Class GameContent
Public Content As ContentManager
Private ServiceHelper As New ServiceHelper

Let me just start off saying that I'm generally new to all programming so if my coding is painful to read I understand. I am currently working on a project that relies on perfect or near perfect collision detection, and I'm not sure whats wrong but sometimes the object being moved completly passes through the object it is supposed to collide at. Here's my coding relating to collision detection so far:
[Code]...
Also, the object, toon, is set to jump with a timer at an interval of 45. Any input regarding how I could make the overall collsion detection better or if I didnt provide the right section of code let me know.

i have 3 PicBoxes on a form. PicBox1=sprite PicBox2=Block1 PicBox3=Block2 I have figured out sprite movement on key down and have figured out simple collision detection for all 4 sides of Block1. My question(s) are:
is there an ideal way to create a method that can be called to handle the collision for all future PicBox's added instead of writting code independently for each key press and each NewBlock along with all 4 sides of the NewBlocks?If I created 100 PicBoxes as obsticles too create a maze type game for my Sprite to navigate through?

I'm designing a system to detect whether a projectile arc impacts a stationary square target. However, the detection is very limited and only seems to work if I use a while loop and a very large area, whereas if possible I'd prefer to animate it using a for loop and have the target somewhat smaller.Here's what I have at present:
Private Sub Timer2_Tick(sender As System.Object, e As System.EventArgs) Handles Timer2.Tick
If (Not errorState2) Then

I am currently working on a game with collisions. I am using a picturebox with an animated gif in the Image property. I am currently using the following function call to detect collision:
pictureboxPlayer.Bounds.IntersectsWith(pictureboxOfBadGuy.Bounds)
When an pictureboxOfBadGuy collides with some of the whitespace of my picturboxPlayer the above line returns true. Does anyone know if VB has detection for images within a pictureBox.

So, I am just trying to get the snake to move after it collides with the picture box. Right now, the snake is moved by using the arrow keys. However, once it collides with "the food", it won't move.

I have code my pictureboxes so that I can move them around my form, however i can move a picturebox under another picturebox. Basically What i would like to be able to do it for a picturebox not to be able to go underneath another picturebox and thus dissapear.For example my picturebox 1 when i move it can go under my picturebox2, I would like it to touch the edges of picturebox2 at most but not go underneath it. I am using visual basic 2008.

I am doing a school project (in programming) on security, and i am focussing on MD5 hashing, this is a used way to store passwords, usernames etc. since i can't really be reversed..Now since i know that MD5 hashes are always 32 byte long there must be a limited number of different "hashes" even though 32 chars with 16 combinations each is a LOT of combos..Now, i will try to make a program where you put in a 32 byte hash and then, by using the principle above with limited hash amounts, try to find ANY string that matches the hash.I have already got code on how to create the MD5 hash but i need to know how to make the strings...it should hash:chr(1)chr(2)...chr(255)thenchr(1) & chr(1)[code]
