Thanks to everyone for their feedback so far, here's another raft of bug fixes and features including smoke screens! Full list of changes: - Smoke screens added: ships may burn oil to create a trailing smokescreen. Lying between two ships, this will obstruct visibility, resulting in highly inaccurate attacks to the other side of the smokescreen - however, a ship possessing radar is unaffected and may fire as normal. An otherwise-obscured ship that is visible to radar will be indicated with an icon. - Bomber behaviour and accuracy should now be unaffected by framerate. - Fixed a bug where aircraft would get in an endless stalemate when trying to get into a dogfight. - Fixed a bug where planes would dump their payload in the sea after a dogfight. - Fixed a bug where planes would not circle correctly when defending their own home aircraft carrier. - Fixed a bug that resulted in the player captain being killed, and NPC captains getting a bunch of clones. The player captain should also not be automatically reassigned to new ships. - Stopped the retreat indicator from showing after a ship's retreat order is cancelled. - Ships can now retreat in custom convoy/blockade scenarios. - Fixed a bug where torpedo bombs do damage while still arming. - AI on ships with defend orders now target enemy ships more sensibly. - Custom key bindings are now saved between game sessions. - Subs now surface and submerge at a slower rate, and now have a cooldown on surfacing/submerging. Submarine AI doesn't forget how to turn when it is firing in range. - Mini-maps now have borders. -Custom battle fleet selection no longer always clears itself when changing fleet settings/country. Now it will only clear the selected ships if the country filter is changed to be enabled. - Gun reloading sound only plays when currently focused ship is under manual control. - The Yamato-class model has been fixed to look more accurate. - The Independence-class model no longer sails around backwards. - War bond reward for taking a port is now proportional to the port's defence level. - Torpedoes now take longer to reload. - End game landing mission defence fleets no longer replenish their ships if the player fails to capture the port. - Missions where you must search for a lost ship no longer have ships so lost they are in the middle of dry land. Lost allied ship missions now have a pulsing UI representing the wide search area, and son't tell you to search for the wrong ship - Fixed a case where custom battles could start up half way between tactical mode and follow ship mode. - All achievements should now be both working and possible to get. - Ships should now unlock slower in the campaigns. - Aircraft no longer respawn until you enter a friendly port to repair and resupply. - Option added to restrict purchasable ships only to those originating from the player's navy. - Shipyard can now be filtered by ship type. - Game no longer gets you to defend an enemy port from an allied attack fleet! - Fixed warbonds not being awarded at HQ if you saved in port then reloaded before getting the reward. - Littorio-class battleship now has a torpedo belt. - Increased warbonds earned for sinking enemies. - Ship stat UIs now show whether ships have armoured decks, radar, and torpedo belts. System status icons now show the integrity of these systems. - Uranium escort ship no longer spawns far ahead of the player's fleet in combat to get itself blown to bits. - Player ships should only retreat if they are explicitly told to do so or if they are both under manual control and the ship is the currently focused on ship. - Ships should now stay in the arena in the relevant scenarios. - Ships now follow player's commands properly when in a blockade mission. - Subs now explode like other ships when killed on the surface. - Removed the less than entirely useful Chitose Mk I ships from the campaign. - Convoy duty battles should no longer display "Victory" or "Defeat" incorrectly. - AI is a lot more cautious about firing torpedoes, should prevent most friendly fire. - Smoke and fire should not vanish so abruptly after being submerged. Smoke particles updated. - Deployable fleet limit in both campaign and custom battles increased to 20. - Optimisations on ships, planes, physics, and particles. - Custom battles sort enemies by point value by default now (same as the player list) - Fixed a bug where a sound could occasionally play much louder than intended. - Submarine engine noises stop whilst submerged.
