Talk:Canvas Radar

setController

that line was already there, now it's there twice - see the end of the Nasal section inside the dialog.

Old Radar

Is there plans for old style forward looking, with sweep-line and fading dots for contacts? Is the plan to show only MP or is the plan to show AI also?

So far, it's dealing with both things - AI and MP, the same way - it would require 3 lines of code to change this to make either of the two modes optional. Regarding the style, that's up to aircraft developers actually - by default, it will be just about providing the corresponding data (positions, altitude, aircraft) - it will be up to the implementor to visualize this in a certain way, i.e. by providing either custom draw routines (callbacks), or simply by providing corresponding SVG/PNG images to customize the appearance of the Radar. Without any Nasal/Canvas experience, people will by default be getting a Radar to similar to the one available on the m2000-5 obviously - but people with some Nasal experience, will be able to easily customize things.

Radar class (Mirage 2000-5)

Work in progress This article or section will be worked on in the upcoming hours or days. See history for the latest developments.

# See: http://wiki.flightgear.org/MapStructure
# Class things:
var name = "RADAR";
var parents = [SymbolLayer.Controller];
var __self__ = caller(0)[0];

SymbolLayer.Controller.add(name, __self__);
SymbolLayer.add(name, {
    parents: [MultiSymbolLayer],
    type: name, # Symbol type
    df_controller: __self__, # controller to use by default -- this one
    df_style: {},
});

var new = func(layer){
    # load the Radar class from radar2.nas
    var path = 'm2000-5/Nasal/radar2.nas';
    io.load_nasal(path);

    var m = {
        parents: [__self__],
        layer: layer,
        map: layer.map,
        listeners: [],
        radar: Radar.new(...),
    };

    # TODO: for non-navaid/FGPositioned layers this needs to be customized to compare objects on the layer
    # layer.searcher._equals = func(a, b){
    #    return 0;
    # }
 
    return m;
}; # ctor

var del = func {
    foreach (var l; me.listeners){
        removelistener(l);
    }
}; # del
 
var searchCmd = func {
    printlog(_MP_dbg_lvl, "Running RADAR search");
    var range = me.map.controller.query_range();
    if(range == nil){
        return;
    }
    return [];
}; # searchCmd
