BATTLEZONE

Version 1.5.2.15

Released 2013-09-30

Closing on on a final release for the 1.5.2 series...

This build fixes a few problems introduced in earlier versions, adds a bunch of handy new Lua functions for mission scripting, and fixes up some networking related issues. It also turns off data execution prevention so it should be compatible with the "classic" Anet from before the connection timeout change.

What's New

Stability

• Rolled back mission save/load culling unlabeled paths
  • It turns out that mission files DON'T exclude AI state...
  • Fixes crash when loading maps with AI state like Capt. Chaos
• Fixed a hang when using Texture32=1 in render.cfg
  • Did this ever actually work?
• Fixed crash in UnitTask::UpdateWeapon when the unit has no active weapon

Scripting

• New Vector Lua functions
  • DotProduct: dot product of two vectors
  • CrossProduct: cross product of two vectors
  • Normalize: scale vector to unit length
  • Length: length of a vector
  • LengthSquared: squared length of a vector
  • Distance2D: 2D distance between two vectors
  • Distance2DSquared: squared 2D distance between two vectors
  • Distance3D: 3D distance between two vectors
  • Distance3DSquared: squared 3D distance between two vectors
• New Matrix Lua functions
  • BuildAxisRotationMatrix: build matrix from angle and axis
  • BuildPositionRotationMatrix: build matrix from rotation angles and position
  • BuildOrthogonalMatrix: build matrix from up vector and heading vector
  • BuildDirectionalMatrix: build matrix from position and direction vector
• Many ScriptUtils functions accept position vector or transform matrix
  • SetPosition
  • GetDistance (second argument)
  • GetNearestObject
  • GetNearestVehicle
  • GetNearestBuilding
  • GetNearestEnemy
  • Goto
  • Mine
  • Dropoff (ConstructionRig uses matrix orientation)
• Added BuildAt function for building at a specific location
  • Armory and ConstructionRig use the location
  • Recycler and Factory ignore the location
  • Easier to use than the Build/Dropoff combo
• Added some scrap management functions
  • GetRidOfSomeScrap: reduce global scrap to a set limit (default 300)
  • ClearScrapAround: remove scrap within range of location
• Added new Start method to mission scripts
  • Can use this instead of doing one-time start in Update
  • LuaMission manages the one-time flag internally
• Added support for locking (and unlocking) team alliances
  • Allows mission scripts to preserve pre-set alliances in multiplayer
  • LockAllies(true) to lock
  • LockAllies(false) to unlock
• Added Lua functions for getting terrain/floor height and normal
  • TerrainGetHeightAndNormal
  • FloorGetHeightAndNormal
• Ported more script utility functions from BZ2
  • GetCircularPos: get ground position in distance and direction from center
  • GetPositionNear: get ground position between min and max radius from center
  • GetPilotClass: get pilot config from a game object
  • SetCommand: general-purpose set command for power users
  • GetMapTRNFilename: get name of TRN file for use with OpenODF
• Added AiCommand table to Lua globals for working with commands
  • Convert between command names and numeric values

Networking

• Split reliable broadcast messages into separate sends
  • The reliable broadcast queue can fill up if a player is unreachable
  • Subsequent reliable broadcasts would then fail
  • ...and a lot of important things use reliable broadcast
• Player list shows grey "?" for ping time of zero
  • When ping hasn't been done yet
  • When ping got 100% packet loss
• Keep Anet alive when leaving game and returning to shell
  • Only destroy Anet if quitting by closing the window
  • Fixes the shell blacking out
  • Problem was introduced back in version 1.5.1.12
• Clear and rebuild player lists on entering the screen containing them
  • Should flush out any leftover player list entries
• Turned off data execution prevention
  • Should allow use of older known-working versions of Anet
  • Newer versions of Anet don't time out disconnected players properly
• MultDMMission AddObject skips forwarding for neutral objects
  • Prevents neutral vehicles from getting an AI process
  • Fixes Z Monolilth's Revenge and other maps that spawn empty vehicles

Gameplay

• Turned off per-polygon collisions for bullets
  • Should fix AI missing some buildings from some directions
  • Ideally targeting would use something besides the geometric center
• Damage no longer affects Person physics parameters
  • Restores the original and expected behavior
  • Person had code for it but never used it
• Detonate Torpedo when close enough to its target building
  • Prevents it from riding up over its target
• ConstructionRig cleans up its build location
  • Snaps position vector to the floor height
  • Flattens facing vector to eliminate pitch/roll
  • Should fix the satellite view "sinkhole" bug

Editing

• Updated mission Load/Save dialog code
  • Fixed filter strings, which needed an extra zero byte at the end
  • Allow directory change for both missions and savegames
• Remove extension from filename before opening mission save dialog
  • Prevents double extension (e.g. usrmisn01.bzn.trn or usrmisn01.trn.bzn)
