I am able to get the lines to change their locations, but the dragHandle rectangles won't update - they stay at their starting locations. I would have thought since the points list changed the updateLinehandles() would fix it.

View 2 RepliesI have made a For next loop with an array. I want all my picture boxes to follow each other within the loop. I have currently been using old code, but not in a loop or array format. The old code works. The array code only makes the 2nd picture box follow the FIRST one. It doesn't loop the rest. I have checked the code and cannot determine any mistakes, else I'm missing out on something I haven't been taught.[code]...

I am trying to have different types of rectangles. I thought something like this would work, but Rectangle is not a class.

View 5 RepliesI have made considerable progress on a game I am making, but one of the fundamentals of it relies on collision detection. At the moment, I am using Rectangle.IntersectsWith() to check "collision" between two PictureBoxes, but I don't want everything all square (graphics, etc). So I set about adjusting regions and have ended up with a circular button (from the MSDN example). What I'd like to know is this: Is there any way I can check intersection between any two OBJECTS, not just rectangles? As in, if the rectangle intersects with or is inside the circle in any way then how do I check it programmatically?

I have an automated electrical tester, I want to create a type of map file so that way the user can select a subset of devices to test. So basically I want to create a type of grid that the user will be able to highlight specific rectangles in the grid so that way the tester knows to test only those specific locations. To start I want to create a 4X4 grid and each individual rectangle in the grid will contain some coordinate information. Does anyone have a tiny example of how I can draw a 4X4 grid, or any thoughts on the best way to do this? The real final map I will be making will have over 50K devices.
View 1 RepliesLets say that I've got the coordinates of two Rectangles, they could be right next to each other or have space between them. I need to draw a PolygonHotSpot around the two rectangles (so it will only cover the two rectangles and the space between them). I've come to find that I have to give the coordinates a clockwise order around the entire polygon, rather than around each rectangle (which works fine for a single rectangle).
So given a list of coordinates, is there a way to get them into the order that I need for there to not be any gaps in my PolygonHotSpot?

View 2 RepliesI have a bunch of rectangles simulating players for a football game I'm designing. I want to find out how many "players" are in between two points on the field. I have a start point (a defender trying to locate the ball carrier) and endpoint (the ball carrier). I need the number of other players in between those two points (I have all of their coordinates as well). The more traffic in the defender's field of vision the harder it will be to find the ball.

View 9 RepliesI need some help calculating physics after a collision, sort of like rigid body physics but just for rectangles, I don't need them to rotate but only to know the x and y speed they leave each other and the angular velocity etc. the collision with the walls work fine since all I'm doing is reversing the speeds of the rectangles (which is probably the wrong way of doing it) but unfortunately this does not not work for the two rectangles colliding with each other, so can some1 lead me in the right direction as to how I can go about calculating this.
View 7 RepliesMy aim is to draw single pixels and rectangles on any web browser.
I ve been thinking alot about this and I think I that there might be 2 ways to do this:
1) Send message api maybe?
2) Direct 3d hook with C++ (Although this is quite complicated)
So my questions are:
Btw the use for it is to detect a certain pixel on the webbrowser and draw on it.
Don't ask why since it is quite complicated and I know also how to use Send message api and I once managed to program a direct 3d hook (but for a 3d game which was based on direct x SDK) with C++ although im not sure if it will work due to webbrowsers dont work with directx.

I have a DataGridView (not data bound, not editable) that displays a bunch of data. I want to draw rectangles around some of the blocks of cells to set them apart visually. For example, I want to draw a red border around the block of cells from row 3 colum 2 to row 6 column 3 so that there is a red rectangle around the 8 cells.I've found how to paint rectangles around individual cells or rows, but I can't work out how to do it for a block of cells.

The robot can shoot bullets, but as I understand I have to draw the bullets from the code.
