hittest

问题 I am working on an application where an image serves as cursor. Now i would like to know at any time over which object the cursor is hovering. Sort of like a HitTestObject(*) where i can then see what object the * represents. Does anyone have any idea how i could accomplish this? (and using the mouse is not an option) 回答1: Put the elements you want to monitor for 'hovering' in a separate array, then add an onEnterFrame listener to the object attached to your mouse that iterates through the

问题 Is it possible for the entire bounds of a form to be hittest transparent without adjusting the visibility of the form? I am using a user32 api call to WindowFromPoint in order to find the control under the mouse. In some circumstances I would like to ignore the existance of a child form that floats in front of the main form (or another child form), but keep this form to ignore visible. Setting the Opacity of the form to ignore to 0 will successfully cause the hittest to pass straight through

问题 I've recently had a breakthrough on the coding for my skee-ball style game. I was having serious issues with collision detection, which the boffins of stackoverflow have helped me solve. I was coding a tween for my object, a ball, to create a smooth roll effect because I hadn't been able to get it to move smoothly otherwise. I finally had a eureka moment and managed to make the object move incrementally instead of teleporting and was able to eliminate my tween. Without a tween, collision

问题 How do I check if a mouse clicked a rectangle? Graphics gfx; Rectangle hitbox; hitbox = new hitbox(50,50,10,10); //TIMER AT THE BOTTOM gfx.Draw(System.Drawing.Pens.Black,hitbox); 回答1: Just a sample quick and dirty, if your "gfx" is a "e.Graphics..." from a Form: public partial class Form1 : Form { private readonly Rectangle hitbox = new Rectangle(50, 50, 10, 10); private readonly Pen pen = new Pen(Brushes.Black); public Form1() { InitializeComponent(); } private void Form1_Paint(object sender

问题 I'm working on a small game and I would like to detect if the player collided with one of the boxes that are placed on the stage. What is the best method to do this, hitTest or hitTestObject ? My code: var hitTestClips:Array = [smallbox, mediumbox, bigbox] //more to come var fps = 60; var moveTimer:Timer = new Timer(1000/fps); moveTimer.addEventListener(TimerEvent.TIMER, onMoveTimer); moveTimer.start(); function onMoveTimer(e:TimerEvent){ player.x += Math.round(1) for(var player:MovieClip in

问题 I'm trying to create a sort of tree diagram such that, if you click on one of the circles, its child circles spread outward with some degree of randomness from the original circle, connected by lines. I have this working, but now what I want to do is make sure that none of the circles collide with each other and none of the lines criss cross. You can see the screenshot for what is currently happening. My code is below. How do I change this code so that it checks for collisions and avoids them

问题 So I have a Movie Clip called hookLine thats added to the stage from my mainEngine class. This empty movieClip is connected to my fisherman Movie Clip and curves to my playerHook Movie Clip. Its added and connected to the stage like so: In My mainEngine function loop: playerHookLine(); Then the Function: private function playerHookLine():void { //Add hook line to fisherman and playerhook hookLine.graphics.clear(); hookLine.graphics.lineStyle(1); hookLine.graphics.moveTo(fisherman.x, fisherman

问题 I know it is possible - somehow through SetWindowLong API or managed property of WPF's Window class at the moment of window's creation... but how to do that exactly I do not know. I simply cannot find the information of how to set style of a window so it could NOT receive any system messages about mouse click on it and any click would go through the window to the underlying windows. Does anyone know that style code or something? 回答1: Set the WS_EX_TRANSPARENT flag for the window's extended

问题 I have a listview which displays a lot of info, but when it's empty I want to overlay a textblock over it which says "No Info to Display" or "Do bla-bla-bla to add info". The listview is set up to respond to mouse clicks, but now if I click on the textblock, those events are routed to the textblock. How can I make these events go to the listview instead? 回答1: IsHitTestVisible = "false" on the TextBlock. 来源： https://stackoverflow.com/questions/6417201/textblock-over-a-listview-how-to-ignore

问题 Is there possible to make hit test in ellipse bound rectangle, like on this image ? 回答1: you can put them both into a border grid and check if it was clicked XAML: <Grid MouseDown="Border_MouseDown"> <Rectangle Width="100" Height="100" Fill="Green" /> <Ellipse Width="100" Height="100" Fill="Orange" /> </Grid> Code behind private void Border_MouseDown(object sender, MouseButtonEventArgs e) { MessageBox.Show("hit it"); } EDIT Just to make it complete here comes the XAML for green regions only:
