Bad Piggies Leading Edge Unity 2022.1 update notes

1. Jet Engine System
The jet engine system is a new class of component system, consisting of three parts: jet engine, fuel pipeline, and fuel tank.

1.1 Jet Engine
[1] The jet engine is responsible for consuming fuel and converting it into thrust. The component materials of the jet engine are divided into two types: normal type and vector propulsion type.
[2] Normal jet engines have a counter-thrust function and their thrust can be adjusted between -1500N and 3000N, but they do not have thrust direction control technology; vector propulsion jet engines do not have a counter-thrust function and their thrust can be adjusted between 0 and 3000N and their thrust direction can be adjusted between -45° and 45°. The thrust control and orientation control technology of the jet engine is supported by a slider button in a new button system.
[3] The fuel consumption per second of the jet engine is 0.2 * |F| + 0.1, where F is the jet engine thrust in kN and the fuel consumption per second is in kg/s.
[4] When the jet engine is turned on to counter-thrust, it will bring some thrust loss, but the fuel consumption will not be reduced.
[5] The tail flame of a jet engine has a scorching effect and can destroy the connection point, and its tail flame length and width will increase with the increase of thrust.

1.2 Fuel ducts
[1] The fuel line is responsible for the connection between the jet engine and the fuel tank. The fuel piping components are classified into three types: fixed connection type, automatic connection type, and valve type.
[2] Fixed connection type fuel piping has only two types of connections, horizontal and vertical; automatic connection type fuel piping can freely connect the four surrounding fuel components in all directions.
[3] Valve type fuel piping also has only two types of connections, horizontal and vertical, but the connection can be opened and closed freely by pushing a button.

1.3 Fuel tank
[1] The fuel tank is responsible for storing fuel and providing fuel.
[2] The total fuel capacity of a single fuel tank is 4 kg, and the unloaded mass is 2 kg. Therefore, the mass of the fuel tank varies from 2 kg to 6 kg as fuel is consumed and replenished.
[3] The fuel tank can supply fuel to a jet engine or receive refueling from an engine such as a nuclear power plant. A single fuel tank has a maximum fuel supply rate of 1kg/s and a maximum refueling rate of 0.5kg/s.
[4] A single nuclear or other type of engine can refuel a fuel tank at a rate of 0.2 kg/s.
[5] The fuel tank can be detonated when subjected to intense wake burns or extreme impacts.

1.4 Fuel system
[1] A connected block of components made up of interconnected fuel components is called a fuel system. Thus, a carrier can have more than one fuel system in it, but a single fuel system cannot be in more than one carrier at the same time.
[2] The fuel supply and consumption mechanisms between each fuel system are independent of each other and do not affect each other.
[3] Each fuel system has a separate jet engine button. Also, each carrier's jet engine will have a general on/off button.
[4] The merging and separation between multiple fuel systems can be controlled by valve fuel lines.


2. Circuit System
The circuit system is a new class of component system, currently consisting of 48 circuit components.
[1] Wire class (no star material): wire, fixed wire, electromagnetic wire, fixed electromagnetic wire.
[2] Basic circuit element class (one-star material): switch, single-blade double-throw switch, resistor × 6, power supply × 3, capacitor × 3, voltmeter, ammeter.
[3] Integrated circuit class (two-star material): ground, high level, buffer gate, non-gate, or gate × 2, with gate × 2, or non-gate × 2, with non-gate × 2, transistor × 2, operational amplifier × 2, time delay × 2.
[4] Electromagnetic class and component application class (Samsung material): interface, electromagnetic interface, wireless transmitter × 2, point charge, electric field generator, magnetic field generator, component trigger, pressure sensor, digital display.
Please refer to the additional circuit system document for the details of the circuit system.


3. Application Interface
The application interface is a new user interface added by New Creation. Currently, the application interface consists of two major functions: the setup interface and the data interface.
[1] The buttons to open/close the application interface are located in the upper right corner. When the application interface is opened, the game will be paused.
[2] At present, the settings interface includes three parts: physics settings, button system settings, and carrier archive settings. You can use the Save button and Reset button at the bottom to save the settings file or restore the option default value.
[3] Currently, the data interface includes three parts: time data, performance data, and device data, which can display the current time, frame rate, memory usage, device model, and other data.


4. New Keystroke System
In the new version, the new key system will replace the old key system. The new key system is independent from the old key system and adds many new features.
[1] The new keys support the carrier key separation mechanism, so the keys of different carriers will be separated from each other. In order to prevent the number of buttons from being too high, the carriers will be sorted in descending order by the number of parts, with the top three carriers having their buttons separated, and the carriers in the bottom three will no longer be separated. You can adjust the carrier button separation mechanism by using the "Max Carrier Separation" option in the settings screen. For example, when the maximum carrier separation number is set to 0, no carrier button separation will be performed.
[2] The new buttons support slider buttons. The slider button is divided into two parts, which can be adjusted up or down to the corresponding value. Also, the slider button's expand bar can be opened or retracted by using a left or right swipe gesture on the slider button. The slider button expansion bar has three sub-buttons: up/down/reset, which are useful for precise operation of the slider buttons.
[3] When the number of buttons increases to a certain level, the buttons become smaller and are divided into multiple rows. When the number of button rows is too large, the display area size will be limited and a slider bar will be provided. You can adjust the display settings of the keys by using the "Key Size Ratio" and "Slider Height Ratio" options in the settings screen.
[4] The keys can be operated by the keyboard. 1~26 keys correspond to A-Z keys, 27~52 keys correspond to A1 (press 1 first and then A) - Z1 keys, and so on. The "Show Part Index Mark" option in the setup screen can be used to display the markings corresponding to the keys.
[5] Support switching between the new key system and the old key system, which can be adjusted by the "Enable new key" option in the setting interface.


5. Solid Light System
[1] Rewrote the collision detection algorithm of solid light source, the collision detection will be more efficient and stable.
[2] Adjusted the power consumption mechanism of solid light source to improve the power consumption during low-speed collision.
[3] Frictionless light pillar: the friction coefficient of light pillar mounted in ice frame, color frame or transparent frame will be 0.
[4] Defocused light components: Light components mounted in transparent frames will ignore collisions with their own carrier parts.


6. Automatic control light source
[1] Automatic control light source is a special class of point light source material, the mapping is fuchsia. Similar to the automatic control door, the automatic control light source can be used to let objects pass through by defocusing specified parts in a certain area.
[2] There are a total of five types of automatic control light source orientation. The first four are automatic control types, when the automatic control light source detects a part in a specified direction, it will defocus its own 5 × 5 area of wooden and iron frame parts, so that the parts can pass through. The fifth type is the manual control type, which will directly defocus the surrounding parts after opening.
[3] When an object is in the defocused area of the automatically controlled light source, the automatically controlled light source cannot be turned off.
[4] The automatic control light source has a certain delay, and may not be able to detect high-speed moving objects in time. The automatic control light source installed in the ice frame will be able to detect high-speed objects and defocus quickly.


7. Remaining adjustments
[1] Add cooling mechanism for nuclear TNT and TNT rocket, cooling time is 0.1s.
[2] New Genesis O/A version adds off-road wheels, hinge plates and track plates.
[3] Hinge plate and track plate connection strength reduced by about 25%.
[4] Added a slider button to the orientation umbrella, so you can freely specify the fixed angle of the umbrella.
[5] Adjusted startup interface and version selector interface.
