I have a control which expands when IsMouseOver is set to true using a trigger. Within that control, there is some textboxes that have some basic validation. My problem is that when a validation error occurs and the user mouses over the Red border around the textbox (almost guarenteed to happen as user moves the mouse to center of textbo...
Back again and have a different question with the same function that I posted before: - (AIEnemyUnit *) hitTestForEnemyUnit:(CGPoint)where { CALayer * layer = [self hitTest:where]; while (layer) { if ([layer isKindOfClass:[AIEnemyUnit class]]) { return (AIEnemyUnit *)layer; } else { layer...
Hello, I've run into an issue where the BitmapData.draw() method isn't accurately subtracting image data from a .png that uses transparency. I've put together a test file that shows this behavior, it's located here: http://www.filedropper.com/shield_1 In a nutshell, a sprite drops from the top of the screen and when it intersects with...
I have a UIView as the container/holder view. Inside that i have a group of UIViews (icons) Think of this as similar to the iPhone's SpringBoard- you have an SBIconList (UIView subclass) with a group of SBIcons (also UIView subclasses) So far, each icon of my icons is draggable, but i'm having problems writing the collision detection c...
In my Canvas I have children with a specific design which includes an ItemsControl.

I have a view hierarchy which contains smaller views on a scroll view. Each view can have subviews in it such as buttons etc. For some reason, buttons on the view aren't clicked; exploring this further showed that while the scroll view receives the touchBegan event, the button does not. Calling the hitTest:event: message shows that the...
Hey all! I have a UIView subclass where hitTest: withEvent: is overridden. Every time a hit test registers, the view logs its tag. Ex: Click Console: You Touched View: 3 You Touched View: 3 You Touched View: 3 My question: Why does it do it three times? I need it to trigger something other than an NSLog and I'm afraid that it will t...

Or should it all be in...
