Update 1.9.205

Dev AndrewGarrison  6 months ago

The 1.9.205 update is now available. It includes a lead indicator for the guns and cannons, tracer rounds for the cannons, and a big update to Funky Trees. Also, we've upgraded Unity to a newer version that has improved performance on Android.

The update should be available now on Steam, GOG, and Humble. It is rolling out for Google Play, iOS, and the Mac App Store, but it may take a few hours and it will be available on Amazon in a few days.


  • Several Funky Trees enhancements
  • Added air-to-air lead predictor for guns and cannons
  • Added Tracer Rounds to Cannon
  • Performance improvements for Android


  • Funky Trees now supports multiple types: Numbers (floating point), Booleans (true/false) and Strings (text). Values will be implicitly converted between these types if possible, for backwards compatibility, so a value of true will convert to 1 if used as if it was a number, and a value of false will be -1.
  • New literals, "string", true, and false.
  • New operators:

    • Comparison: "=", ">", ">=", "<=", "<"

    • Boolean Operators: "&" (and), "|" (or)

    • Ternary (selection) Operator: a ? b : c (essentially if a then b else c)

  • New parameters:

    • GForce (omnidirectional "force" acting on the pilot, in g)

    • VerticalG (vertical component of G)

    • SelectedWeapon (the name of the selected weapon, such as "Boom 50")

  • New functions:

    • ammo("Weapon") (where Weapon is the name of a weapon; for instance ammo("Cannon") returns the number of cannon rounds available as shown in the weapons drawer. ammo(SelectedWeapon) [note no quotes, as it's the variable not the string value] returns the ammo for the selected weapon)

  • Special functions: These are functions that have special functionality can store previous values, something not previously possible

    • rate(x): the rate of change of x.

    • sum(x): the integration of x over time.

    • smooth(x, rate): the output follows x, but only at a maximum speed of x units per second.

    • PID(target, current, p, i, d): A PID controller with the parameters p, i and d.

  • Some potential parsing bugs were fixed with - signs.
  • This shouldn't break old expressions, if it does please report to me (@WNP78)
  • activationGroup inputs now support entering FT expressions (which are taken as Boolean values)
  • Control surface and beacon light inputs now support entering FT expressions
  • Debug Command:

    • Open the dev console in level and type DebugExpression "expression" (for instance, DebugExpression "AltitudeAgl > 10").

    • Use ClearDebugExpressions to clear the list.

  • Equality operator now works with multiple types.
  • Expression tester can now use # replaced for " as dev console doesn't like quotes. For example you can enter the command DebugExpression ammo(#Cannon#) so that quotes don't interfere with the dev console syntax.
  • Add inputs: GearDown, Latitude, Longitude, PitchRate, RollRate, YawRate
  • Change float to bool conversion to x > 0 (a number will be interpreted as true if it's greater than zero, it used to be greater or less than ,but not equal to, zero.)
  • Fix gyro handling of "None" input.
  • AG values over 8 now revert to default value rather than being casted to booleans by FT.


  • Added impactDamageScalar, explosionScalar, flashSpace, and flashScale XML properties to cannon

    • flashSpace sets the simulation space for cannon muzzle flash, either "Local" or "World"

  • Updated Fine Tuner with cancel MultiSelect when no parts are selected
  • Added designer option to select Air, Ground, Multi-Role option for Cannon.


  • Fixed IAS algorithm
  • Fixed bug breaking guns alternate firing
  • Fixed reticle persistence issue on bomb predictor
  • Fixed layer mask for part select tool
  • Fixed attach point select with finger aid
  • Fixed designer platform not instantly showing
  • Fixed a bug that prevented Trim and VTOL sliders from displaying for combined input, such as "Trim + Vtol"
  • Cannon wind sfx no longer play while paused

    You should really improve the AI, First when they are set on agressive mode, The AI will automatically retract its landing gears even when on ground and tries to take off....ITS MY ONLY WISH

    I would stop complaining about mobile no longer having mods if you just gave us tank treads.

    @09thiccfish that was the longest sentence I've ever read

    @Zoowarp yea I kinda get that but it's a good idea. the tank treads on the other hand was something that should of been in the last update adding Cannons and all but that's why I'm not comfortable suggesting thing to devs it's alot of work making a game and sometimes harder to update it way to many people make suggestions and makes it hard for devs and gets really complicated at times I do not know where I was going with this

    @09thiccfish ahh I see
    I mean I agree but it would mean changing the mechanics of simpleplanes

    @Aircat56 @LockheedMartinbois i remember hearing that the reason they are not added is because the processing power of one island is too much for most mobile devices, especially older ones, so it isnt planned i dont think

    @Zoowarp I mean in simple rockets they have the ability to get out of the seat they are assigned to I ment a playable pilot for example spawn in two planes have the ability to get out of one and walk over to the other and pilot that one something like that. I fell that being able to walk around or in your creations would add tones of possibilities to the game

    @09thiccfish character? you can do that - grab any part, open overload and change id to Passenger-1 and you get a crash test dummy in an airliner seat

    In the next update a few suggestions, add the characters and seats like the ones in simple rockets and editable tank tracks. I don't want to sound demanding but these are decent ideas.
