I've got a map of the country I reside in and have all the railroad stations marked out. i've got all the co ordinates for each station and distances from one station to another.My question is what would the best way be to get the shortest distance between two stations, keeping in mind that one station may run through many others and there is more than one way to get there. See pic attached
[Code]...
You could check to see if the distance across the form minus the distance across the picture box is equal to the horizontal location of the picture box to see if it's on the right side. For the left side, just check if the horizontal location of the picture box is 0.
View 2 Repliesassuming i have an isoceles triangle, where i know the height + base width, how
can i calculate the width of that triangle at 1/3 of the distance from the point + 2/3 of the distance from the point?
i thought it'd be simply 1/3 base width + 2/3 base width, but my drawing is +/- a few pixels when i resize it?
so i got a program that i wanna derive in. like this:you right in this x^4+x^2-4x+8 and then the program will derive it to 4x^3+2x-4..how do i do that? like this x^4+x^2-4x+8 and then doing this 4x^4-1+2x^2-1-4x-x+8-8..how do i find the places to add and then drawing -1 to the right places?
View 3 RepliesProblem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..
split the string into seperate words which i have done. however i also need to find the longest and shortest word which i just can't do and its driving me mad.

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'
[Code]...
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'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.
