GDI: Make Drawn Object Move And Follow Path/Points At Constant Speed?

Nov 13, 2011

I've come across a very basic problem which I'm sure has a basic answer.Forgive me but I haven't programmed in years and this just a hobby of mine..My problem is that I need a drawn object (say an ellipse) to move to the cursors location when I click. Imagine an adventure quest style game where you view your character in birds eye view, and it moves according to where you click on the map.I can draw the image fine, and move the image around fine - it's more so the formula I'm using which I'm a little stumped on.I have certain requirements though.

1. I need a timer that constantly updates the drawn object's (lets say character from now on) location. Each tick will essentially be the character taking 1 step towards the cursor's location.2. At the end of each tick of the timer, it'll will invalidate the form/control to invoke the paint event, and of course, the objects location will be be updated.It sounded simple enough to create a linear equation based on the objects original location and the location of the cursor when I click.However, that will not give it a fixed speed.If say for example, the gradient (rise/run) between the cursor location and objects location is very steep, the object's y-velocity will be greater than that of the x-velocity

Make A Settings Field Points To A Constant?

Jun 27, 2010

I would like to make a Settings Field (SKey) to point to a constant (Q)

Where the Settings Value will be modified by the user using Text box and public const Q = keys.Q so I can let the user modify a hotkey to what ever he wants I wished to use the following code for registering the Hotkey

Public Const Q = Keys.Q 'My.Settings.SKey should points to this variable
'There will be more constants for other keys
RegisterHotKey(Me.Handle, 1, HCtrl + HAlt, My.Settings.SKey)
the problem is:

the program use MY.settings.SKey as String and I cannot define it as integer where the input is a text

Make Object Follow Mouse On MouseDown And 'Stick' On MouseUp

Apr 14, 2011

I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose).Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here)Then, on the label's MouseUp event, I want it to either stay in its current position or return to its original position, as determined by the value of a boolean variable set by another object's MouseEnter property.Note, if it would be easier to work with, I can change the grid to a canvas in a cinch. I'm guessing that would be desirable.

How do I make the object (label) follow the mouse cursor inside the grid/canvas, but not outside of it? This needs to happen on the MouseDown event of the label.How do I make the object "stick" in its current position? (From this, I can probably figure out how to make it return to its original position on my own.

Make Labels Move Up And Down In Panel By Themselves At A Set Speed?

Feb 9, 2010

I am currently making a VB.Net game for my end of the project, but I have found myself in a deadlock. I was wondering how to make labels move up and down in my panel by themselves at a set speed. Also left and right by themselves. I've tried a couple different methods but none seem to work. They either lag or I can't seem to set where there bounds are.

VS 2008 Make Picture Box Move Along The Path?

Jun 24, 2009

As seen below in the screenshot I used the following code to draw a line from CA to CA 1.1

g = pbxMap.CreateGraphics
g.DrawLine(pen1, D.v(path(t)).x, D.v(path(t)).y, D.v(path(K)).x, D.v(path(K)).y)

Is there anyway to make the red picturebox at CA to move along the line drawn to CA 1.1? Something like the google driving directions where a car will moving along the path from a starting point to a ending point..

Functions To Draw Line Or Move To Points

Jul 19, 2009

Currently there are functions to draw line or move to points, commonly known as LineTo(x,y) of MoveTo(x,y). I am wondering if there is also a LineTO or MoveTo function(s) for 3D, i.e. LineTo(x,y,z) or MoveTo(x,y,z).

Application.Startup Path Points To My Debug Bin When User Executes ?

Jun 29, 2012

I sent the application exe to a user to test and they get an unhandled exception error and the details show my personal My Documents Folder/DEBUG path from the project. So I tried to use Application.ExecutablePath but when I release that it points to "My Documents" Folder (not the debug) folder. The file to open is in the same folder as the exe is in but for some reason the error occurs because the application is not looking for the file using the path where the EXE was launched from. Here is my code that relates to the section giving my users a problem:

from the module
Public Class shrd
Public Shared ocSess As cSession

Build The Shortest Path Between Any 2 Points In This List - Develop Some AI Code For A Game ?

Aug 17, 2010

I'm trying to develop some AI code for a game I'm creating. I have a list of x,y coords and I need help figuring out what I can use/do to build the shortest path between any 2 points in this list. I would like to build a function that I can pass a list of valid X,Y coords to use when generating the path, start point, end point, and have it return a list of points, which would be the shortest path between the start and end point, using the list of points supplied. I have looked at A* and Dijkstra's, but am having problems implementing the algs in code, as all this seems graph based.
