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.
View 3 RepliesSearching the internet for an example of backtracking in VB.Net has proven fruitless. All the examples I found were either in a language I don't understand (making it impossible for me to convert it to vb.net) or they contained zero commenting (making it difficult to actually understand what is going on).Does anyone have an example of backtracking in VB.Net? Commenting would be useful so I don't have to decipher single letter variables.

my question is regarding working out the direction of the smallest angle between two vectors in 2D. I am making a game in C++ where one of the obstacles is a heat seeking missile launcher. I have it working by calculating the vector between the target and bullet, normalising the vector and then multiplying it by its speed. However, I am now coming back to this class to make it better. Instead of instantly locking onto the player I want it to only do so only when the bullets vector is within a certain angle (the angle between the bullets vector and the vector bulletloc->target). Otherwise I want it to slowly pan towards the target by a degrees thus giving the player enough space to avoid it. I have done all this (in a vb.net project so i could simplify the problem, work it out then re write in in C++). However the bullet always rotates clockwise towards the target even if the quickest route would be counter clockwise. So the problem is working out the direction to apply the rotation in so the smallest angle is covered. Here is my code so you can try and see what I am describing:
Function Rotate(ByVal a As Double, ByVal tp As Point, ByVal cp As Point, ByVal cv As Point)
'params a = angle, tp = target point, cp = current point, cv = current vector of bullet'

I had was to work out the bearing of the two vectors and if the difference is greater than 180 degrees, rotate clockwise otherwise rotate counter clockwise

I have a Access program and I'm using VBA code in the background to run Winunzip using shell command.

Load playlist button is on my Form1 and Form4, and settings is on my Form6, and this happend every time I load anything, open anything, so my app remembers last opened folder. Is there any way that I can return my path to apps path? I need to mention that this applies only to Windows XP, idk why, because on my win7 it works just fine.

View 2 RepliesI need to get a path from a resource file...
im planning to do a midi player; I've tried it via the included .NET and DirectX component, both needs a path to the audio file (String)....
how do I get a path from a resource file?
ps.: there's also a way to play via a stream-link/stream-player, where
my.resource.<filename> is enough, as this declares the directstream.... but I really need to get a path.
I guess this one is pretty basic, yet i have not been able to figure out.So here's the deal, my application uses an external exe to generate some txt files that the application needs for a use case. Since hard coding the path of such exe would be hideously wrong in so many aspects i would like to include a little configuration option for the user, so he can specify the path of the external exe for the application to be used.I also would like to have something like that for the path of the Database I'm actually using.
