SimplePlanes Update 1.7 - Damage Control

The 1.7 update is now available! Here is the trailer showing the new features.

Here's what's new in 1.7:

Parts
  • Countermeasure Dispenser (Chaffs / Flares)
  • Torpedo
  • Unguided Rocket
  • Cleaver (cruise missile)

Features
  • Part Transform tool
  • Improved Damage Model
    - Parts can now take damage instead of instantly exploding
    - Engines can catch on fire
    - Control surfaces, RCNs, rotators, etc can be shot out
    - Wings can leak fuel
    - Improved look and performance of bullets
  • Countermeasures
    - Chaffs and flares can now prevent and break locks
    - Aircraft size and engines also play a role in how difficult it is to acquire a lock
  • WW2 Destroyer with Flak Cannons
  • WW2 Torpedo Mission
  • Number entry on Fuselage Properties
  • Redesigned Fire buttons

Minor Features
  • Cycle designer part properties buttons in reverse via right-click
  • Improved mirroring in the designer
  • Disable Auto-Sizing of nose cones after it has been manually resized
  • AI fire countermeasures
  • Bridge Demolition Mission is a bit harder
  • Collisions between dynamic rigid bodies now downscale the impact force if the other body has less mass.
  • Bomb explosions have been updated
  • Some smoke damage particle effects have been updated
  • Damage for various weapons has been tweaked as well as the health of the ships. It may take more to sink them now.
  • AI plane tweaks (dogfighting should work better now)
  • Bombs and missiles that have been fired are no longer affected by explosions (easier to carpet bomb now).

Bug Fixes
  • Fixed part menu scrolling
  • Fixed bug that allowed missiles without cameras to load terrain.
  • Fixed a couple bugs related to races.
  • Fixed some issues with wing leveling mode.
  • Fixed a couple bugs with control surface deflection calculations.
  • Fixed a bug with the 'Loading...' label getting stuck when attempting to enter a level with banned parts.
  • Fixed a bug with AA missiles exploding at the wrong position.
  • Fixed a bug with mirroring scaled parts.
  • The fuselage rise/run limits have been increased to 5.
  • Fixed a bug with part property sliders sometimes showing an incorrect slider position.
  • Fixed a bug with incorrect calculations for control surface deflection.
  • The propeller engine no longer restricts modded engine power to within normal range when selected.
  • Made some tweaks to the missiles related to them traveling at their specified max speeds.
  • Reduced the distance that a piston snaps to its target position, so it's less jarring when looking closely.
  • Rockets now check the impact force when collisions occur, no longer blowing up if sneezed on.
  • Fixed an issue with rotators failing to find a joint after being mirrored. It's still not perfect, but much improved.
  • The tire squeal no longer plays at the camera.
  • Fixed bug with center of mass being incorrect for bodies with 0 total mass. (fixes 0 mass missile wobble on detachers)

XML Modding
  • Ability to invert input from XML by placing a minus sign in front of the input
  • Updated the boolean type inputs for input controllers to return -1 or 1 rather than 0 or 1. This allows the use of the input controllers min/max values to be used in conjunction with the boolean input types.
  • Add firingDelay XML Option to Existing Weapons
  • Hidden XML Option for Self Destruct and Burn Time on Rockets.
  • Add Support for input="Activate1" (that’s AG1) on InputControllers
  • The “disableAircraftCollisions” attribute on guns can now be used to prevent your bullets from colliding with your plane.
  • Missile XML now supports a 'maxSpeed' attribute. Existing planes (but not new ones) with low mass missiles will now auto-upgrade to a higher than normal max speed.
  • Added "invertType" option to the InputController. Defaults to "axis" for most parts and to "output" for rotators.
  • XML support for scaling bullets (now set with "bulletScale", not the part's scale - old planes auto-upgraded).
  • XML support for disabling gun muzzle flash ("muzzleFlash" - true/false)

Mod Tools
  • Added Unity version check to the mod builder window.
  • Removed warning about multiple mods loading the same exact assembly.
  • Added load priority for mods to better manage mod dependencies.

Thank you so much to all of the beta testers who helped us squash an insane number of bugs!

About This Game

BUILD AIRPLANES


You have the tools you'll need to bring any airplane to life. Snap parts together to build your airplane's body. Place engines to add thrust. Design and attach wings and then strap yourself into the cockpit and see how it flies.

DOWNLOAD AIRPLANES


Over 100,000 airplanes are available to download for free from SimplePlanes.com Find anything from old WW2 bombers to next generation fighters to sci-fi spacecrafts. You can upload your own airplanes and rise through the ranks from a bronze builder to a gold level builder.

DYNAMIC FLIGHT MODEL


Flight simulation at its finest. Every little change you make in the designer impacts how the airplane flies. Weight distribution, thrust, lift, and drag are all calculated continuously while flying. Parts can break off in spectacular fashion while flying due to over-stress or by hitting something. The fun won't stop there though. You can keep on flying even with a missing wing if you've got the skills.

CHALLENGES


Climb into the cockpit of one of your custom aircraft and see how it does in the challenges. The challenges will keep you entertained for hours. Land on aircraft carriers, escort bombers, dodge surface-to-air missiles, race through courses, and so much more.

SANDBOX


Use all available parts to build airplanes with no restrictions. The sky is the limit. Literally.

MODDING


Modding is fully supported so you can build your own parts and environments. Download our Unity package which includes specially designed tools to aid in designing and building mods which you can then share with your friends and the community.
