With luck, I'll be able to script a fire ladder (if I manage it, this will be used instead of Hydraulic Platforms to reach the second floor of buildings, because HP units are used for rescue from higher floors (I haven't seen anyone do floors higher than the second, so it might not be possible to include this) and for putting out fires from above along with water towers). I'm already learning a fair bit about the scripting system (but I hardly know any functions at this point).
Honda CR-V RRVs have strange lightbars on the roof, does anyone know who builds them and what model they are? Maybe Code 3 Javelins?
Also, I have worked out my dispatch system, many thanks to scrivs for his detailed information on how the WMFS works and various other important details:
Each emergency vehicle will have its own (probably boolean) variable. When the variable is true, that vehicle is available for call-outs. If false, it's not. When you click, for example, the "Dispatch PRL" button, what it will do is go through a list of checks. It will first check if the closest station has an available PRL. If not, it will then check the next closest, and then the next, and so on until it finds an available unit.
When it finds one, it will dispatch it, and the time will vary based on which station it's been sent from (I have this information with me, courtesy of scrivs). The time will not always be the same (will vary for different times of day), and I may use real time (this is the problem of small time scales, you can't really make things as accurate as you might want).
If I can't make fires spread at a slower rate than they do in-game, however, I will have to use game time, else you would have an inferno across all your city before the fire engines arrive.
All this might take many lines of code, but one way or another, this will happen

Lots of useful information from scrivs formed this:
This system also allows me to implement the system of automatically sending a Command Support Vehicle. When you send one or two pumps, and then decide to send two to four more, a CSV will be sent as well.
When you have a few more, a prime mover will come bearing an Incident Support Unit.
If you have significantly more, then text will appear suggesting you dispatch the PRWT (Pump Rescue Water Tower), COBRA (a significantly more powerful water pump (in real life, it can shoot water through brick)), or HVPU.
The time period between which a dispatch is deemed a "make-up" (when more units are required) will be ten or twenty seconds.
For these, you get "white helmets" (?) and a special manager guy turning up in expensive cars (presumably with blue lights on).
If you have more than 8 firemen in breathing apparatus, a BA emergency crew will be sent out (probably from D061 Cradley Heath).
If the amount of BA-wearing firemen increases further, text will appear on the screen suggesting you send a BA Main Control Unit.
This is the order of closest stations to Kings Heath (again, information courtesy of scrivs):
C8 Billesley
C5 Kings Norton, Pershore Road South, Cotteridge
C4 Bournbrook, Bristol Road
C1 Highgate, Moseley Road
C7 Ladywood, Icknield Port Road
B1 Solihull, Streetsbrook Road
C9 Hay Mills
C6 Northfield
A6 Ward End
C2 Woodgate Valley
This might not be completely accurate, but I feel that it will do, really, and besides, the only difference you will notice is the writing on the side of the fire engine xD
