[Ql-Users] Air Traffic Control Sim
So, I have started on my ATC project. I thought I'd document here my struggles, learning, and how I did it. I'm hoping it'll engage other BASIC programmers in discussion, and maybe you (yes, YOU!) will help me if you can see me getting stuck. Please remember this is primarily an exercise in improving and restoring my mind after a bump on the noggin. I'm fighting against some short term memory problems. I'm using the Mac version 1.0 of Q-Emulator, and SuperBASIC on JS ROMS with TK2. I'm writing it to run at standard QL speeds, and to run at a consistent speed on faster hardware. So far, I have written out a table of some of the variables I need, and their valid ranges, and how I will auto-generate pseudo-random flight numbers, altitudes and speeds for various aircraft profiles. Next, I will work out a co-ordinate base for a local airport. I have chosen Bergstrom because it is local to me, and I know where all the beacons and VORs are. I have decided that there are hard bits (it's a technical term) in this project for me (I know to some of you, these will be trivial, but to me, the solution isn't obvious): 1. I'll be keeping the aircraft, their altitude, speed, direction, intended alt, speed and direction, etc, in a large DIMmed array that can hold 10 aircraft. Landed or departed aircraft will be removed from the array and any newer aircraft will be scrolled up one spot. Like in real life, the oldest aircraft is always at the top of the stack. There will be inbound and outbound aircraft. Inbound aircraft will be announced and placed at the edge of the screen, and outbound aircraft will originate from the runway when given flight instructions and clearance to take off. The aircraft must always maintain separation of 1000 feet altitude and 3 miles horizontally. Checking all the aircraft against each other to see if any violate airspace of others, or have collided, might be hard to code. 2. I need to write a command parser to accept input from the user, namely instruction for flights. There is a standard way of doing this and I will follow this. This means I need to accept input and add it to a stack, then when it is entered I need to parse it to ensure valid, rational input. Once I know it is within bounds, I need to carry out the action, i.e. instruct the aircraft to follow the instruction. 3. I need to write routines for landing aircraft. Once instructed to land, I need to detect when they cross the glide-slope, and get them to follow it to landing, land, then remove themselves from the stack. 4. I need to write a ticker... No matter the speed of the hardware, the game should run at the same speed. This means events should be triggered at an interval, complete (even on the slowest hardware) before the next interval. This interval should ideally be 1 second, but could be 2 seconds. Despite the ticker, the input routines need to continue unaffected. Responsiveness of keyboard input is essential. 5. I need to plot this on a 512x256 screen. I can't let flights go off the edge of the screen. 6. I need to detect valid landings of arrivals and proper exits of departures. 7. I'd like to add an element of realism where planes, including departures, can declare emergencies. Well, those are the hard bits I can see up front. I can foresee earning a little money next week, so maybe a compiler will be in my future? I'd prefer an easy compiler over a good compiler. I would also love to have an external USB floppy so I could save my stuff somewhere other than my OS X HD... Maybe later... In the mean time, I'll work on this and keep sharing. Hopefully it'll work out. Dave ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Hi Dave, being a private pilot and an ATC sim fan myself this is a very interesting project. Looks like a nice initial concept. Are you going to share the source code for this somewhere (github, sourceforge, ...) ? Maybe couple of different types of aircraft and related performace values.

I decided to do it this way for two reasons: The first being that t is quite lightweight to code. If the fourth plane in the stack lands, I simply need to call a FuNction to move slots 5-9 up one. This makes a lot of other things simpler. For example, there will never be a plane after the empty slot. Planes would then be self-ordering, and it makes display issues a lot easier. The second reason is that I'd like to process the plane movements together, then process the screen handling, then invoke the ticker to detect the next time I need to process the panes. The only time workload becomes a problem is if the work cannot be done in one tick. At that time, I might need to look at what I have done and re-write it a more efficient, yet obtuse way. I have Lightning on microdrive here, but it's frustrating that I cannot get it onto the mac emulator easily - also, I can't count on everyone else having Lightning. The screen handling is by far the slowest part of this. Like in real life, the oldest aircraft is always at the top of the stack. There will be inbound and outbound aircraft.

I'd like to add an element of realism where planes, including departures, can declare emergencies. And planes trying to land on the wrong runway, not on the glide path, abort the landing, and so on. A game like this shouldn't be too realistic - otherwise it would become boring. People doing this in real life get a lot of compensation for doing their boring routine job right (Travelling a lot by plane, I hope so, at least) For simplicity, I won't create those situations, but if a plane that is asked to land on a runway never crosses the glide-slope, I need to detect that as the plane passes the runway, and have the plane do something rational, like climb, increase speed, hold heading, and contact you for for a go-around.

I understand Turbo is the one that requires precise coding. Given I've revoked my old hand status and consider myself a beginner again, it might not be for me. I'll give it a shot though. In any case, I'll be posting my code. For you all to laugh at. Which you will. And that will be educational for me. :) Dave ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Looks like a nice initial concept. Are you going to share the source code for this somewhere (github, sourceforge, ...) ? Maybe couple of different types of aircraft and related performace values. Would add nice flavour when you can't tell a Cessna to maintain a 2500 fpm climb ;) Or tell a LearJet to slow down to 80 on the final. Best of luck with the project and especially your recovery!
