Game Programming :: VB2008 - Space Invader Collision Detection?

Dec 28, 2010

i've looked up several tutorials on what i should do to create a collision detection, but im not too positive on how to function my ideas and convert them to code.Basically, i'm creating a space invaders like-game that is 2D Mario-themed (sprites used).I am using a panel for my enemies and Mario is being controlled by the movement of arrow keys and space button shoots.The problem is I can not make my bullets collide with the enemies to make them disappear. This piece of code is what i've got so far with the collision detection :

Code:
'*******************************************************************************************************************************************************
' Collision occurs whenever the pctShoot(podoboo) hits any of the enemy
' When blnTrue, both pctShoot and the enemy disappear

[code].....

While I'm at it, i have another question in concern; but this is not really related to collision but:How do you make an object move down automatically using a timer but make it appear randomly?Like any space invader game, the enemies are shooting back at the hero to make it appear more challenging right?(using Visual Basic 2008)

Game Programming :: DirectX Collision Detection?

Aug 11, 2010

I have loaded two mesh's from .x files onto the screen, a map and a sprite. The sprite moves around, but because they aren't colliding the sprite goes straight through the mountains, and straight over the undulations. I have looked for a way to find the co-ordinates of a particular spot on the mesh, as I figured by finding the X and Z co-ordinates of the sprite, I could just set his Y co-ordinate to be the same as the map, and he would 'stick' to the ground... however I don't know if this is possible, and I haven't found it yet.

Game Programming :: Detect A Collision With The Edge Of A Form

Oct 2, 2009

I am currently investigating vb gaming and have set up a test project to move an object; it moves fine. The problem is that when it reaches the edge of the form it continues to move and eventually leaves the form entirely. So my question is how do i work out if my object has touched the edge of the form?

Game Programming :: Space Invaders .NET Compact Framework?

Oct 2, 2008

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

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.

Collision Detection And Bouncing Off?

Apr 28, 2009

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.

VS 2010 With Collision Detection?

Feb 23, 2012

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.

Collision Detection For Multiple PicBoxes?

Dec 21, 2011

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?

Collision Detection Not Operating As Intended?

Apr 7, 2012

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

Is There Collision Detection Within Bounds Of PictureBox?

Nov 7, 2011

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.

Interface And Graphics :: Collision Detection And DirectDraw?

Aug 28, 2009

I'm using DirectDraw to create a (very) simple little movement game... (so far not really a game, but hey, gotta start somewhere) And I'm having a little trouble with my collision detection... ok, it's probably not conventional collision detection, but I'm just learning so far...I have a few surfaces set up etcetc, and have animated a sprite on a tile based background... but the problem is whenever I collide with a certain tile (which I've set as unpassable) from the top or the left, it screws the position of my player immensely... this is quite a headache as I can't seem to see a problem...

ps. Another thing, I can't seem to be able to open my pictures without using the entire directory.

Player Movement/collision Detection/global Variable?

Dec 7, 2010

how to do collision. my previous attempts involved trying to see if the player was touching -any- non-collidable object, but i've reversed it so that objects themselves detect if the player is interacting with them and respond appropriately. i still cannot find a way to completely stop the player from walking into walls, but this is what i have so far.

Public Class mymap
'movement function/class/etc?
Private Sub mymap_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
Dim Loc As Point

[code].....

is there a way to put a sub in a sub? see notes in the code above and hopefully you'll see what i mean.d last of the craziness, are global variables possible? i can't seem to find a tut on them. in the passable sub it doesn't recognize the tiles variable and says it isn't declared, though it is declared in the hedge1 sub.

Game Programming :: Spinning Reel - Fruit Machine Game For Windows Mobile Device

Feb 16, 2011

I'm trying to make a simple fruit machine game for windows mobile device.

I can create the game easily enough and flip through pictures in a picture box to display the correct symbol.. but what I'd like to do is do a proper spinning reel, but have no idea where to even start.

What I have is a list of images in an imagelist (or individual files) - what I'd like is them attached to each other and moving downwards, preferably as though it were going around a drum but just them moving would be a start.
