The previous note is incorrect. A portal closed with a func_portal provides a default occlusion distance of 450. This might be enough to silence sounds with small radii, but the ones with larger radii can still be heard, though they're more quiet. |

1 – Changed the way sound reaches the player. Instead of using a distance-based method to determine sound loss across portals, use a dB-based method. Discard the fixed occlusion amount across portals with varying occlusion based on door sound loss spawnargs, location separators, and portal settings entities. 2 – Created a portal settings entity that acts like a location separator w/o creating a location boundary. It carries a sound loss spawnarg that can be applied to AI-heard sounds only, Player-heard sounds only, or both. 3 – Allowed visportals to touch doors with the addition of a new spawnarg, “transparent”. This keeps the portal from closing when the door closes. This allows us to use location separators and portal entities to add further adjustments to sound loss across portals. 4 – Allowed sound loss across an opening or closing door to vary based on the size of the opening. To the player, any sounds coming through an opening door will increase in volume, and decrease as the door closes. 5 – Fixed the “text” entity so it can use the “developer” mode to show its text. The docs said you could toggle the text on and off by toggling the developer mode, but it didn’t work. 6 – Fixed a problem with hearing sound while sitting on the “Player Ready” screen at the start of a mission. Sounds were starting before the player hit the attack button, which caused nearby sounds to be heard through portals, whose occlusion values weren’t set up until a few frames after the attack button was pressed. Fix was to delay starting sounds until after the occlusion values were installed on the portals. 7 – Allowed scripts to adjust the sound loss on portal entities and location separators. 8 – Fixed a bug in a method that determined how “open” a door was. The method only worked for doors opening counter-clockwise, but gave strange results for doors opening clockwise. 9 – Fixed a bug that was occluding sound on a visportal closed by a func_portal. Now no occlusion occurs, allowing sounds to pass through these closed portals without losing volume. 10 – Allow open visportals to occlude sound if they have a touching location separator or portal settings entity. This lets mappers muffle sounds through smaller openings that otherwise would come through loud and clear. rev. 5695: Script_Thread.cpp Script_Thread.h BinaryFrobMover.cpp BrittleFracture.cpp BrittleFracture.h Entity.cpp FrobDoor.cpp FrobDoor.h Game_local.cpp Misc.cpp Misc.h Mover.cpp SndProp.cpp SndProp.h SndPropLoader.cpp SndPropLoader.h RenderWorld.cpp RenderWorld.h RenderWorld_demo.cpp RenderWorld_local.h tr_local.h snd_emitter.cpp snd_local.h snd_world.cpp rev. 13326: misc.def Also committed a test map, “playersound” for testing.

Committed a change to reduce the amount of time spent finding sound paths from a speaker to the player. rev. 5696 snd_world.cpp |

Next round … Add 10dB loss to doors for player only. This brings sound volumes through doors more in line with what they were before the sound changes were made. rev. 5711: FrobDoor.cpp And rev. 5713: snd_world.cpp |

Next round … Adjustment to sound passing through an opening door so that it reaches full volume at the 50% open position instead of a 100% open position. rev. 5732: FrobDoor.cpp |
