Hello all, I am trying to make a flight control system in node red. The description of the project/simulation is as follows: Inject nodes to show or update the position of UAV in the Map A Speed Slider which when the speed is increased will make the UAV move in the map in any direction (for e.g. …

I did this: let move = flow.get("location") || 0 ; let bearing = move.bearing; if(msg.topic == "up"){ if(bearing = 0){ bearing = 0; } var up = { name:"SIMULU", bearing:bearing, layer:"gps", popped:true } node.warn("bearing=" +bearing); …

Please provide the entire function node.

var R = 6378.1; // Radius of Earth var dist = 100; // Distance in meters var theta = (dist / R) * 2 * Math.PI; // Angular distance in radians var speed = 0; var lat1 = 0.0; var lon1 = 0.0; var lat2 = flow.get("lat2") || 0; var lon2 = flow.get("lon2") || 0; if(msg.topic == "lat"){ lat2 = msg.p…

Here: if "location is not stored in the flow yet, the move will be 0 let move = flow.get("location") || 0; Then if move is 0, you cant ask any property from it because 0 has no properties let bearing = move.bearing; Here you need to have double == if(bearing = 0){ bearing = 0; } Like this …

I want to do something like this: let move = flow.get("location") || set_it; let bearing = move.bearing; then change the values to N, S, E and W depending on the bearing of the marker, but it gives me the error: "Cannot read property 'bearing' of undefined", which I cannot seem to understand as wh…

I see you added node.warn's in but you didn't identify them so you don't know which is which. Change them to someting like node.warn("in down if - bearing=" + bearing)

Being it is close to Christmas and I'm about to have two small sick children arrive I'll tell you part of your issue. In each of the IF routines you end with a return msg; which ends the function node. so your last bit of code move.bearing = bearing; flow.set("location", move); return msg; never …

Changed as per your suggestion, but this error will make me loose my job. var R = 6378.1; // Radius of Earth var dist = 100; // Distance in meters var theta = (dist / R) * 2 * Math.PI; // Angular distance in radians var speed = 0; var lat1 = 0.0; var lon1 = 0.0; var lat2 = flow.get("lat2") || 0; …

Solved. This is my current flow: [ { "id": "01732bfeeaa6afce", "type": "ui_text_input", "z": "594f4d4bfd9f7699", "name": "", "label": "Initial Lat Position", "tooltip": "", "group": "b4ebae93d455bbc5", "order": 2, "width":…

Good work, so can we close this thread?

(Sorry) This might be a bit off-topic on what you are trying to achieve. Here's a link to a tutorial I wrote( just over 3-years ago) for my IoT students to track aircraft movements using FlightRadar24.
