Instance Method Details

#number ⇒ Object

Returns the number of the axis or button responsible for the event.

# File 'ext/joystick.c', line 295

VALUE js_event_number(VALUE klass)
{
	int *fd;
	Data_Get_Struct(klass, int, fd);
	return INT2FIX((fd && *fd >= 0) ? jse[*fd].number : -1);
}

#time ⇒ Object

Returns the time, in milliseconds, that the event occurred. TODO what is time 0?

# File 'ext/joystick.c', line 332

VALUE js_event_time(VALUE klass)
{
	int *fd;
	Data_Get_Struct(klass, int, fd);
	return INT2FIX((fd && *fd >= 0) ? jse[*fd].time : -1);
}

#type ⇒ Object

Returns the type of the event. Normally this should either be either :axis or :button. If “something goes wrong”, the numerical type is returned.

# File 'ext/joystick.c', line 310

{
	int *fd;
	Data_Get_Struct(klass, int, fd);
	switch(((fd && *fd >= 0) ? jse[*fd].type : -1) & ~JS_EVENT_INIT)

		case JS_EVENT_AXIS:
			return ID2SYM(rb_intern("axis"));
		case JS_EVENT_BUTTON:
			return ID2SYM(rb_intern("button"));
		default:
			return INT2FIX(((fd && *fd >= 0) ? jse[*fd].type : -1) & ~JS_EVENT_INIT);
	}
}

#value ⇒ Object

Returns the value of the event, which is internally a signed 16-bit integer. It can range from -32768 to 32767.

# File 'ext/joystick.c', line 346

{
	int *fd;
	Data_Get_Struct(klass, int, fd);
	return INT2FIX((fd && *fd >= 0) ? jse[*fd].value : -1);
