InputEventScreenDrag

Back to API Reference

Namespace: Electron2D

Summary

Represents a screen touch drag event.

Declaration

public class Electron2D.InputEventScreenDrag : Electron2D.InputEventFromWindow

Remarks

Drag events carry the current pointer position, motion delta and pressure. Velocity values remain zero until frame timing is connected to touch input dispatch.

Thread Safety

Instances are mutable and are not synchronized; use them from the input dispatch thread that owns the event.

Since

This class is available since Electron2D 0.1.0 Preview.
