Ok. So I have a program I have made to calculate angles. i have a line for true vertical and I need the program to draw the line at a given angle. Basically, if I put 82 in textbox1, I want the program to calculate the cordinates where that line sits on the X axis, The y axis is always picturebox1.height, So the y axis isn't important here, just the x axis.
What would I do to calculate this angle into a visual graphic?
I Have created a program (see below) that enables you to use you cam. You then draw a line and calculate the angle. The purpose is that I do alot of work with remote control cars and need to acuratley set toe and camber angles, it takes to long with the "old" method So I am creating this little program. ok, so, lets see what I want to do. Well, the first thing I would like to do is draw a line from top to bottom of my picture box dead center of left to right, this is dead center of the cam so the bottom of your item should be posistioned to meet the bottom of the centre line. I then draw a line from bottom to top of the objects angle. I then use the dead center line and the line I drew to calculate the angle.

View 1 RepliesI'm trying to make a mini map for a 2d space shooter of mine; I've for the math down (I think) for when an item should appear on the mini map, but the problem is the graphic. As it stands, the graphic spills over the edge of the mini map graphic and disappears only when it's fully outside. I need it to crop the image, or at least not show it off the mini map graphic.I thought of using the sourcerect rectangle of the spritebatch.draw, but it seems to me that would only work for the right and bottom section, as I can adjust the size of the rectangle. I haven't tried this yet, but I will soon. Can the location of the source rectangle be changed in relation to the graphic that it is a part of being drawn so that I can use that to crop the left and top sides?

View 1 Repliesi am having a problem with either my algorithm for restricting an angle between lines. I have a diagram of my problem at the following linK: [URL] In the above diagram, i know the positions of the Points marked on the diagram. The Black lines represent where the lines are currently, i want to move the lines so that they are at right angles to one-an-other (i.e: they are perpendicular) if they are moved to not be so. This is represented by the gray lines.

i am trying to get the angle of a line in relation to the x axis. The line is being drawn in a picturebox. So its the Upper right quadrant of the cartesian plane ... but its flipped over the x axis.im using this code
a=pt(1).x
b=pt(1).y
c=pt(2).x
d=pt(2).y
z=math.atan2((c-a),(d-b))*(180/math.pi)
The issue is that the line im drawing is almost parallel to the x axis but its returning a value of roughly 90 degrees .It seems like it is giving me the angle in relation to the y axis, but not being super good at the math myself im not exactly sure what to change here.
I have a form i have made to calculate angles, well, I have now added a check box to reverse the angle and have got it to reverse with no problems. The problem I have is, when I uncheck the checkbox, The line doesnt revert back to normal posistion.Here is the code if someone could point me in the right direction cause I am lost now.

I am working with a graphics program in VB to move an image around the Form. I'm trying to create barriers that cannot be crossed. At first, I tried to represent this with a 2D array, but this proved too complicated. For now, I'm trying to create a series of rectangles. What I want to happen is when the point the image is anchored at intercepts one of these rectangles, it will either be prevented from moving or sent back to where it was directly before the image moved. I know there is an intercept command, but I've been unable to figure out how to use it in this content. The code I have is below.
Public Class Form1
Dim PlayerSprite As Image
Dim BGImage As Image
[code]....
As I said, this is to create a graphic barrier. However, I expect to make a number of these Rectangles?
