Patch 1.12.118.0 (17 December 2021)

Bug fixes and improvements
Patch 1.11.106 (15 October 2021) FUSELAGE SLICING

Use the new Fuselage Slicing to cut holes in your fuselages. The main purpose is to allow cutting holes for your new cockpits, but players have already found many other creative ways to use this new feature.
NEW AND UPGRADED STOCK CRAFTS

Several stock crafts have been upgraded with new, immersive cockpits. Wasp, Gator 2, Kicking Fish, Bush Plane, Pigpen, Hellkeska, Sea Plane, Twin Prop, and Vertigo all updated. P-51 was updated with two variants, P-51-B and P-51-D.
SEVERAL NEW PARTS

Tons of new parts are available to build your own custom cockpits:

Gauges – Instrument panel gauges used to display a piece of information (such as altitude or airspeed) with radial indicators.

Artificial Horizon – A standalone artificial horizon which appears to contain a ball, but does not require a cut–out in the panel to show depth.

Labels – Label parts, to add text or numbers to builds. Supports inputs within curly brackets, curvature, outline, gradients, and rich text formatting.

Simple Throttle – a standalone push–pull style throttle.

Fighter Throttle – a standalone slider type throttle with button.

Yoke – a standalone yoke part, with two handles.

Lever – a simple standalone lever that can be bound to any axis.

Control Base – A part that acts as a rotator and a grippable control, grip parts such as the joystick top can be placed on top of it. Each axis it takes an input that is also its output. This means it cannot be an arbitrary FT expression, but can be a flight control or a custom variable name.

Buttons – Interactable buttons that can be pushed to do stuff

Switches – Interactable switches that can be toggled to do stuff

Flight Computer – A 'cockpit' part with no camera that can act as a primary cockpit part.

Modern Joystick – A modern–style joystick grip part with a trigger and buttons.

Basic Joystick – An older looking joystick grip part with trigger and buttons.

Cylinder Grip – A basic grip part in the form of a cylinder.

Refuel Probe – A part that enables the “assist” mode of refueling from a drogue.

Refuel Drogue – Transfers fuel to other craft, designed to be trailed on a winch. Only used on the Tanker.

Seat – A simple seat part with built in camera.

Advanced Seat – A stronger fighter jet style seat. May add ejection functionality in the future.

Cockpit Canopy – A prebuilt glass canopy for 1–seat cockpits. Can open.

Basic Frame – A skeleton for the interior of a cockpit, which everything can stick to.

Modern Frame – Similar to Basic Frame, but with side areas for placing controls and a central divider between the pilot's legs.

Hollow Glass – A hollow glass part with tweaked rendering so the inside is not visible from outside, and the inside can be coloured differently to the outside. Recommend turning down the smoothness in the inside, as strong reflections from the canopy do not reflect the cockpit and can be very disorienting.

Wing Landing Gear Bare – new version of the wing landing gear with a different wheel and no attached fairing.
Air To Air refueling

Put a Refuel Probe on your plane and spawn a tanker through the spawn sandbox AI dialogue.
Variables System

An aircraft now has a list of numeric variables that can be written to from certain sources and read from all FT expressions.

Each assignment to a variable also carries a “priority” which allows you to choose which assignments will override others if multiple attempt on the same frame.

Variables are mainly written from the aircraft’s list of variable setters, which is accessible from a button in the bottom right of the designer. Each row in this isn’t a variable, but represents an assignment to a variable (a variable is automatically created if it’s ever assigned to). This means you can assign the same variable multiple times in that frame, or have it updated from multiple sources. A setter takes in an FT expression and stores its result to a variable. It also has an activator function which can disable the setter but this is XML–only right now and pending a GUI.

Variables can also be written by part modifiers that have designated outputs. Currently the only one of these is a helicopter rotor that outputs its RPM to the variable "RotorRPM" for a gauge, but this may be expanded on in the future.
OTHER NEW TWEAKS AND FEATURES

Added emission option to paint. Emissive paint do glowy. We assume no liability for exposure to radiation.

Added part hiding feature in the designer. You can conceal parts, show or hide concealed parts, invert the concealed part list, and other things.

Added 5 extra color slots for default themes.

Added support for Slant Angle to all fuselage parts.

Maintain camera orientation when double-clicking to focus on a non-wing part.

CTRL+Click on the Input button in Part Properties to enter a Funky Trees expression.

Changed minimum zoom distance in the designer to from 0.5 to 0.05.

Hold left-shift to pan/rotation/zoom the camera at 10% normal speed.

Changed name of designer categories: "Cockpits" to "Cockpit Basic".

Added XML attribute for the CowlFlaps on the WWII engine to hide the engine cowl (bool attribute is named "hide").

Added support for loading AI aircraft across multiple frames.

Added optional liftScale to Wing.State XML element.

Added optional throttleResponse attribute to Engine.State XML element to override the part type's throttleResponse.

Added "audio" XML attribute to JointRotator modifier so the annoying audio can be disabled.

Added Rpm1, Rpm2, Rpm3, and Rpm4 to the flight data accessible from Funky Trees. These predate the RotorRPM variable and are on a priority based system, supporting up to 4 sources. They can't be remapped manually, but they do support Car Engines as well as heli rotors.

Added collider attribute to Fuselage.State element to allow more accurate colliders on fuselage parts. Possible values are Auto, Basic, ConvexMesh, and NonConvexMesh. Note that NonConvexMesh will still be convex in flight due to physics limitations.

Hold left-shift to pan/rotation/zoom the camera at 10% normal speed.

Added support for custom names for cameras.

Added TargetLocked and TargetLocking variables accessible from Funky Trees.

Made connections more predictable when using the “Add Section” button.

Updated the camera part to optionally support the gun reticle and missile targeting

Updated the cockpit modifier to optionally disable the camera vantage.

Updated the cameras to optionally act like a cockpit camera, using a priority based system.

Updated the first person camera part to support an adjustable 'up offset'. Prior to this tweak, a hard–coded offset of 0.5 was used, meaning the camera would render half a meter above the visual mesh for the camera. This can now be adjusted. With a value of zero, the camera should render at the same position as the visual mesh.

The designer paint panel now dynamically adds colors to match the number of materials defined in XML.

Updated to Unity 2020.3.19
BUG FIXES

So many bug fixes. Too many to list here.
Patch 1.10 (25 September 2020) Features:

Added Glass Fuselage part. This supports transparency, as well as hiding its front and back faces when connected to other glass parts. The glass will also shatter instead of exploding like other parts do. For some info on how to tweak its material to make it look nice, check the part's description text by clicking/tapping on it in the parts list.

Added "Smooth Front" and "Smooth Back" options to fuselages. This alters the surface normals to make the shading of the joint appear seamless, without changing the actual shape of the parts. For this to work, there has to be another fuselage connected to the front or back connector and lined up.

Added an explosionScale

XML attribute to bombs and missiles (inlcudes torpedos). Default values are:

Boom 25: 0.8

Boom 50: 1.6

Torpedo: 0.8

Inferno : 1

Cleaver : 1.8

Guardian: 1

Interceptor: 1

Added 4 input expressions (Funky Trees) variables:

TargetSelected, true if there is a target selected, otherwise false.

TargetHeading, the heading to the selected target in degrees.

TargetElevation, the vertical angle to the selected target in degrees.

TargetDistance, the distance to the selected target in metres.

Added a setting on iOS to change the framerate limit. (vSync already overrides the framerate limit on all other platforms)
Tweaks:

Upgraded to Unity 2019.4.8 (LTS).

Turned down physics update in the designer (there's not even any physics in the designer, so hey) for a small-ish FPS boost.

By popular demand, allowed blueprint images to be shown while taking craft screenshots for an upload.

Added Toggle Fast Forward input.

Added support for the iOS Files App.

Added a fuseInput parameter to cannons to set shell fuse on FT.
Bug Fixes:

Fixed an issue with connections that could lead to craft not loading in the designer - if you have any saved craft that would fail to load, try loading them again now.

Fixed bug with using the rate of the speed of the aircraft in input expressions.

Air-to-Air cannon prediction now disables when predictor quality set to off.

Fixed string comparison in input expressions on mobile platforms.

Orthographic keybind (default "C") disables when control is held, so it is not activated when trying to Ctrl+C.

Casting from number to boolean in input expressions is now consistent across platforms (now it evaluates to n>0).

Fixed some FT values on scaled cockpits - this could affect existing craft, if they have active stability programs and squashed cockpits.

Using speed variables in input expressions on AI craft now return correct values.

Fixed a bug in overload with default part scales.

Fixed a bug where the magnet would stop working when the aircraft fired a weapon.

Fixed a bug where the magnet may not work when set to AG 8 and within close proximity to an object on start.

Fixed FT = operator not working on mobile (SelectedWeapon, boolean comparison).

Fixed "MultiRole" attribute not working on missiles.
Patch 1.9.205 (20 March 2020) FEATURES

Several Funky Trees enhancements

Added air-to-air lead predictor for guns and cannons

Added Tracer Rounds to Cannon
FUNKY TREES

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.
TWEAKS

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

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

Funky Trees

Nicky brewed this up in his experimental laboratory. They aren't your traditional trees, but rather an expression parser so you can write actual code that is evaluated for input controllers. Intended for XML modders, these allow you to blend inputs in any way you can imagine. For example:

More details here.

Added support for switching between Metric, Imperial, and Nautical unit systems.

Added Ground Speed, Indicated Air Speed, and True Air Speed modes.

Added weapon naming and multirole weapons.

Added sliders for Metallic and Smoothness to paint flyout.

Patch 1.8.3.2 (18 March 2019) FEATURES

Added Helicopter Parts

Main Rotor: Highly customizable helicopter rotor system.

Tail Rotor: Counteracts torque from the main rotor system(s) and provides yaw control.

Added Winch part: Rotating drum that extends and retracts a cable. Works great with the new magnet part.

Added Magnet part: Turn it on with an AG and this powerful electromagnet will stick to anything with the slightest hint of metal.

Added Hollow Fuselage part: The visuals are hollow, but the collider is quite solid.

Added Arresting Hook part: Helps to slow down quickly when landing on the aircraft carrier

Added Catapult Connector part: Tells the aircraft catapult where to connect to your plane. (Not strictly required for catapult connection.)

Reduced part drag calculation precision in order to improve performance for calculating drag for large crafts.
BUG FIXES

Fixed a bug where fuselage inlets would revert the player's changes when immediately selecting another fuselage inlet before closing the Part Properties.

Fixed a bug where the nudge part inputs would not work until the transform part panel was opened

Fixed a bug where the download progress bar would report very high values on Mac

Fixed bug which could cause the propeller engines to hunt for target pitch and never be able to reach it...could cause wild swings in lift.

Fixed a bug where the fuselage properties would revert player's input text if their number ended in a zero.

Fixed a bug where a designer undo step would not always revert the craft to the correct version.
MODDING SUPPORT

The build process and format of mods has slightly changed. When building mods for Windows/Mac, Unity will need both the Windows and Mac build components installed (mod tools should warn you if this is not the case). PC/Mac mods now include separate asset bundles for both platforms in a single mod file. You will likely noticed larger mod file sizes with this update. A new 'Debug' build option is available which builds the mod only for Unity's current target platform with the DEBUG symbol defined (should be a faster build than the other build options).

A bunch of classes received interfaces which have been added to the mod tools. You may be able to get away with using less reflection code by taking advantage of these interfaces. These live in the "Jundroo.SimplePlanes.ModTools.Interfaces" namespace.

Fixed a bug with the starting locations reflection proxy code which may have caused the spawining of AI aircraft to fail.

Fixed a bug with mod level duplication when saving mods.

Fixed a bug that prevented the cloning of parts with a hinge joint.

Mod Builder Window style/layout tweaks

Some additional info on changes and upgrading can be found on the modding wiki
POTENTIAL MOD-RELATED ISSUES

Since we updated Unity with this upgrade, several mods are likely to be broken. For this reason, mods will be automatically disabled the next time you start SimplePlanes. Nathan has been able to find some very clever ways to allow some mods to still function, but several mods will be broken with this update. We recommend turning them on one by one and testing each one to verify whether or not they still functions and don't cause any problems.

XML Modding

Ability to invert input from XML by placing a minus sign in front of the input
