When your notifies need to affect gameplay reliably, use PMP.

Otherwise, use the existing notify system.

• ProNotifySystem
  • Gameplay Timers triggering notifies reliably
  • Trigger notifies placed prior to the anim start time
  • Ensure notifies trigger on anim end, even if they were not reached
• Multi-mesh support with Driver, Replicated Driven, and Local Driven Montages (gas-pro branch only)
  • Driven Montages optionally match the duration of the Driver montage
  • Example use-case: TP character mesh Reloads (Driver), so their TP weapon plays a matching replicated driven montage (replicated so simulated proxies play the montage), FP character mesh and weapon both play their own Local Driven Montages (not replicated)
  • Additional Blend in and out parameters (gas-pro branch only)

• Anim Notify States supported Start and End - But not Tick
• Only supports notifies on Montages not their AnimSequences
• Trigger Settings such as NotifyTriggerChance will not do anything
  • You can optionally override ShouldTriggerNotify() in C++ to implement this behaviour yourself
• SimulatedProxies typically don't get calls to play montages thus cannot operate on timers and don't support Pro Notifies as a result
  • SimulatedProxies as well as Editor can optionally use the engine's notify system instead
• FAnimNotifyEventReference does not exist for notify callbacks
• CustomTimeDilation is a per-actor Time Dilation, however there are no callbacks or even setter for this property
  • ProNotifySystem relies on USkinnedMeshComponent::OnTickPose to detect changes. If your dedicated server doesn't tick the mesh pose it will not work.
  • There is likely a performance overhead with enabling this

• ProNotifySystem is very different to Epic's implementation
  • Triggering behaviour may not always be identical - but you can report this if you believe it is a bug
  • Use this for gameplay critical systems only, and use Epic's for cosmetics
  • Because SimulatedProxies and Editor run on Epic's system, results may not be consistent

There are 3 branches available. The precompiled binaries are for gas-pro branch only as it contains all the features.

• main PlayMontagePro() only, no GAS dependency, supports Pro Notify System only
• gas PlayMontageProAndWait() with support for gameplay abilities, supports Pro Notify System only
• gas-pro: PlayMontageProAdvancedAndWait(), with support for multiple driven meshes and gameplay events and additional blend parameters

Code was used from GASShooter for multi-mesh/montage support and events

• Switch to pale yellow notify color to differientate

• Stop checking ShouldBroadcastAbilityTaskDelegates() for EnsureBroadcastNotifyEvents()
  • Causing unintended behaviour and these notifies already track their broadcast states themselves
  • Fixes a bug with ending montage due to ability end in particular.
• Add EnsureBroadcastNotifyEvents() to OnDestroy()
• EnsureBroadcastNotifyEvents() from OnMontageBlendingOut() no longer inappropriately ensures end states for notify states
• Re-order UPlayMontageProCallbackProxy broadcast/ensure for consistency with other nodes

• Initial Release
