How to use it ?

[eusru]

I follow the ReadMe QuickStart but still crashed.

I compiled this plugin
got some warnings like no FlecsLibrary in MegaFLECS.build.cs

In Project Settings, I have Value specified for ECSProjectileDeveloperSettings and Mega FLECSDeveloper Settings

And Click Run Crashed.
I think there is some steps I make wrong .
so could you pleasae provide Any other tutorial for this ? like Video or Image & Text,

crashed at
check(ProjectileSubsystem->ProjectilesNiagaraManagerActor)
in ECSProjectileBlueprintLib.cpp line 44

I checked code , found that ProjectilesNiagaraManagerActor will never be initial or set a value , it is a nullptr

Did you set the developer settings BP?

"Important: The projectile subsystem needs to have a AECSProjectilesNiagaraManagerBP set in the ECSProjectileDeveloperSettings for it to spawn in the world! This is what sets the AECSProjectilesNiagaraManagerBP actor to get spawned by the subsystem and the default Niagara Entity ID stuff."

I could have had a static asset ref in there but those are generally evil...

Also FWIW I have moved on to the making a sample for the ECS plugin that comes with UE5 (Mass)

FLECS has a lot more features but Mass is more integrated with Unreal.
