This plugin is used to detect taps on the screen. Use it as in this example:
object "Debug Mode - My Tapping Test" is "debug-mode-plugin"
{
fun onLoad(debugMode)
{
tapDetector = debugMode.plugin("Debug Mode - Tap Detector");
tapDetector.subscribe(this);
}
fun onUnload(debugMode)
{
tapDetector = debugMode.plugin("Debug Mode - Tap Detector");
tapDetector.unsubscribe(this);
}
fun onTapScreen(position)
{
// position is a Vector2 given in screen coordinates
Console.print("Tapped at " + position);
}
}
*/
object "Debug Mode - Tap Detector" is "debug-mode-plugin", "debug-mode-observable"
{
observable = spawn("Debug Mode - Observable");
touchId = -1;
touchMoved = false;
touchInitialTime = 0.0;
tapTimeThreshold = 0.25; //0.2;
fun onLoad(debugMode)
{
touchInput = debugMode.plugin("Debug Mode - Touch Input");
touchInput.subscribe(this);
}
fun onUnload(debugMode)
{
touchInput = debugMode.plugin("Debug Mode - Touch Input");
touchInput.unsubscribe(this);
}
fun onTouchBegin(touch)
{
touchId = touch.id;
touchInitialTime = Time.time;
touchMoved = false;
}
fun onTouchEnd(touch)
{
if(touchId == touch.id) {
touchId = -1;
if(!touchMoved) {
if(Time.time <= touchInitialTime + tapTimeThreshold) {
observable.notify(touch.position);
}
}
}
}
fun onTouchMove(touch)
{
if(touchId == touch.id) {
touchMoved = true;
//touchMoved = (touch.deltaPosition.length >= 0.5);
}
}
fun subscribe(observer)
{
observable.subscribe(observer);
}
fun unsubscribe(observer)
{

}
