15/01/2023 - v1.2

Features

• Allow teams to share vision [#8]

  • Vision sharing can be controlled in different ways (Use AGKFogOfWarVolume::VisionSharingSetting to configure):

    • UseGenericTeamSolver (Old Behavior):

      • we use unreal engine builtin FGenericTeamId::GetAttitude()

      • If Teams are Friendly then vision is shared

    • UseFogOfwarTeamSolver (new default):

      • we use Fog of War internal solver that will replace the default attitude solver used by FGenericTeamId

      • Authority can control which team is visible by which using AGKFogOfWarVolume::SetShareVisibility.

      • Teams that share vision with another become ally (i.e FGenericTeamId::GetAttitude() will return Friendly).

      • Vision sharing does not have to be symmetric.

      • You need to call SetShareVisibility(A, B, true) and SetShareVisibility(B, A, true) to make it symmetric.

    • UseBoth:

      • Both above systems are used separately

      • Friendly teams do not need to share vision and enemy teams could share vision.

      • Calling AGKFogOfWarVolume::SetShareVisibility only change visibility and has no impact of the Team attitude.

  • Use WITH_GENERICTEAMSOLVER=1 so force UseGenericTeamSolver at compile time

• Team Vision Caching (Authority Only)

  • If vision sharing is reciprocal (i.e if Team A shares its vision with B and B share its vision with A) then the vision texture are the same and TeamB vision drawing can be skipped and use TeamA texture instead

  • Can be disabled at runtime with bCacheSimilarAllyVision inside the FogOfWarVolume

  • Can be disabled at compile time with WITH_TEAMCACHING=0

• OnSighted/OnOutOfSight Events (Authority Only) [#11]

  • Runtime Toggle: bBroadcastSightingEvents inside the FogOfWarVolume

  • Compile Time Toggle: WITH_SIGHTING=0

• Flying units

  • Can be disabled at compile time with WITH_FLYINGUNITS=0

  • Without flying units:

    • Only the obstacles heights are taken into accounts.

    • Vision height is not kept after the initial vision computation.

  • With flying units

    • the unit above sees everything below units below see nothing above

  • NOTE: in practice most RTS do not have true flying units, i.e ground units will see flying units.

  • Disabled by default

• Allow server to tick at a different speed than clients [#9]

  • By default dedicated server only run at 30 tick per second.

Bug Fixes

• Fix Team color [#10]

• Fix replication issue were clients had characters left as visible after server paused the replication.
