[Geomoose-users] Auto-refreshing

[Brian Fischer]

We have an old GM 2.2 web app that animated through some weather radar.  Here is the code that was used for that.  Not idea if this would work in GM 2.6 or not.

<tool name="animate_layers" title="Weather Radar" type="javascript" selectable="false">
			WeatherLayersAnimator.toggle_animation();
		</tool>

AnimateLayersExtension = new OpenLayers.Class(GeoMOOSE.UX.Extension, {
	current_layer: -1,
	is_animating: false,
	layers_to_animate: [],
	interval_id: -1,
	interval_delay: 1000,

	animate: function() {
		this.is_animating = true;
		/* go to the 0th frame */
		this.current_layer = -1;
		this.next_frame(this);

		/* because of scoping rules with setInterval, we need to pass the class back to the function */
		/* Also, this function variable thing is done because IE doesn't properly implement setInterval */
		var instance = this;
		var my_func = function() {
			instance.next_frame(instance);
		}
		this.interval_id = window.setInterval(my_func, this.interval_delay, this);
	},

	stop_animate: function() {
		clearInterval(this.interval_id);
		this.is_animating = false;
	},

	toggle_animation: function () {
		if(this.is_animating) {
			this.stop_animate();
		} else {
			this.animate();
		}
			
	},

	next_frame: function(instance) {
		instance.current_layer+=1;
		if(instance.current_layer >= instance.layers_to_animate.length) {
			instance.current_layer = 0;
		}

		for(var i = 0; i < instance.layers_to_animate.length; i++) {
			if(i != instance.current_layer) {
				GeoMOOSE.changeLayerVisibility(instance.layers_to_animate[i], false);
			}
		}
		GeoMOOSE.changeLayerVisibility(instance.layers_to_animate[instance.current_layer], true);
	},

	load: function() {
	},

	initialize: function(layers,delay) {
		this.layers_to_animate = layers;
		if(delay) {
			this.interval_delay = delay;
		}
	},
	
	CLASS_NAME: "AnimateLayersExtension"
});

GeoMOOSE.UX.register('AnimateLayersExtension');

Guys, I am really lost here. Some snippets or pointers in the right direction will be very welcome :-)

Thanks,
Matej

>> I don't believe this was carried over.  You would likely need to write an extension to do this.  There is example code in GM 2.2 I believe.  I have used it once for some weather radar layers.
