Vary max aircraft and spawn rate based on multiplier

[liam-m]

Part of #5

• Max aircraft = current multiplier (e.g. x7 => maxaircraft = 7)
  • make sure this doesn’t make anything unusual happen when the multiplier decreases (e.g. aircraft disappearing)
• Spawn rate should be set so the number of aircraft is generally between maxaircraft bounds (e.g. at x5 there should be 3-5 aircraft on average, at 7x between 5-7 etc.)

Well, I think we should make it double the multiplier, it would be much better for consistency. I can do that tomorrow afternoon.

It depends if we want there to be up to 20 aircraft - I've gone off what @Matidy has said in the UX and priority task documents. 

[jacob135135]

I believe our current max multiplier is 5 and having just 1 aircraft on easy until it gets to its exit point 10 times would be a bit boring.

[liam-m]

No, it's 10. See UX document for details about multiplier and Priority Task document for more information about how this should work

[jacob135135]

I see, it was recently changed, my bad. In any case that means the multiplier intervals should be amended/ more rewards for planes successfully leaving. Will ask Matt tomorrow.

[liam-m]

Okay, happy for you to work on this now. If you need clarification consult those two documents and ask Matt. If you need help implementing I can give you a hand :)

3 3 5 7 10

[jacob135135]

pressing ctrl can still spawn more planes (is not bounded by max aircraft)

[liam-m]

That's fine

[jacob135135]

spawn rate used to be 12, now it is 60/ maxAircraft => same rate when multiplier is 5, half the rate when multiplier is 1 and twice the rate when multiplier is 10

[LiamWellacott]

Just had a thought, when they are marking it we might need to make it explicit that the game can support 10 somewhere in case they cant play well enough to get the number increased?

[liam-m]

Sounds like it should go in the user manual
