Virtual joystick control (Silverlight, Windows Phone 7/8)
Recently I created a simple "virtual" on-screen joystick control for my needs. I just wanna to share my code with developers to reduce development time :)
Download control and sample; add VirtualJoystick.xaml & VirtualJoystick.xaml.cs files to your project and enjoy. The control is too simple for the detailed description; in short, VirtualJoystick has properties:
- public double Angle; // current angle in degrees from 0 to 360
- public double Distance; // current distance (or "power"), from 0 to 100
- public double AngleStep; // how often should be raised StickMove event
- public double DistanceStep; // how often should be raised StickMove event
public event EventHandler StickCaptured
// raised when user tap and hold the joystick
public event EventHandler StickMove;
// raised when angle or distance exceed a threshold values set by AngleStep and DistanceStep properties.
public event EventHandler StickReleased
// raised by the end of manipulations
I'm not a good artist so I've tried to reproduce assets from this perfect article (with working sample) by Hemanth Sharma
If you can draw a better, more "photo-realistic" base and knob, please let me know, I'll be glad to include your work to the project. But please, the XAML drawing only (no png/jpg etc.)!
