问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . Pardon the funny title. I've created a little graphic demo of 200 balls bouncing and colliding, both against the walls and each other. You can see what I have currently here: http://www.exeneva.com/html5/multipleBallsBouncingAndColliding/ The problem is that whenever they collide with each other, they disappear.

WPF C# Finding the corners of a transformed RectangleGeometry

由 怎甘沉沦 提交于 2019-12-02 21:35:15
问题 I'm trying to do some hit testing on a Rect I've drawn with several RenderTransforms pushed to the Canvas' DrawingContext. I've applied the same rotate/scale/translate transforms to a RectangleGeometry so I can get the bounds of the final drawing. However, the .Bounds property on RectangleGeometry returns the axis-aligned bounding box, while I need the oriented bounding box. In short, I need some way to find the corners of the actual transformed rectangle so I can perform hit/collision

问题 Im developing a test game with some imageviews on the screen. with the finger, i am moving another imageview. I want to detect when the imageview moved by the finger has touched another imageview. ¿Wich is the best way to achieve it? I can't find info about it on google... Thanks 回答1: I'll answer the general question - find out when two views overlap : private boolean viewsOverlap(View v1, View v2) { int[] v1_coords = new int[2]; v1.getLocationOnScreen(v1_coords); int v1_w = v1.getWidth();

I'm not entirely sure how the coordinates are getting NaN. // Variables var numBalls = 200; // number of

How do I detect pygame collisions?

I'm currently developing a small game with pygame and I'm having a hard time figuring out a way to check for collisions. I've found this question , but I can't use the pygame.sprite.spritecollide(player, wall_group, True) because my called player isn't a 'sprite', it's a class that I've created (that uses the functionality of normal shapes ( https://www.pygame.org/docs/ref/draw.html )). If anyone could figure a way that I can detect collisions and explain to me shortly about the difference between 'sprite' and just a normal shape like circle/rectangle I would appreciate it. To use pygame's

cocos2d v3 collision detection

问题 I'm trying to inspect collision collision of two bodies, but collision detection callbacks are not being fired. Here is my code: 1) My CCScene implements CCPhysicsCollisionDelegate protocol 2) I set collision delegate for physics _physics = [CCPhysicsNode node]; _physics.gravity = PHYSICS_GRAVITY; _physics.debugDraw = YES; _physics.collisionDelegate = self; [self addChild:_physics]; 3) For each of two body I set a collision type body1.collisionType = @"body1"; body2.collisionType = @"body2";

C# panel move with collision

由 …衆ロ難τιáo~ 提交于 2019-12-02 07:20:25
I am new to C# and Winforms and try to make a moving panel. It should move right until the end of my window and then back left. It should bounce from side to side. But the only thing happened after hours of trying is that it moves left and stops. Using this form tools: Timer = tmrMoveBox (interval: 50) Panel = pnlBox Label = lblXY (for showing the X and Y coordinates in the form) Here are my first best try: private void tmrMoveBox(object sender, EventArgs e) { if (pnlBox.Location.X <= 316) { for (int i = 0; i <= 316; i++) { pnlBox.Location = new Point( pnlBox.Location.X + 2, pnlBox.Location.Y)
