LaunchBlast Has no Detail - Can't Add Particles

[Jeff_Miller]

I’ve followed the lectures in building the projectile and bringing the explosion in to add to the projectile. LaunchBlast exists as a component of Projectile under Collision Mesh, but the Details tab shows nothing. Without Details, there’s no place to add the particles.

Here’s the Projectile.h line declaring components:
UPROPERTY(VisibleAnywhere, Category = “Components”)
UStaticMeshComponent* CollisionMesh = nullptr;

UPROPERTY(VisibleAnywhere, Category = "Components")
UParticleSystemComponent* LaunchBlast = nullptr;

And here are the .ccp sections:
CollisionMesh = CreateDefaultSubobject(FName(“Collision Mesh”));
SetRootComponent(CollisionMesh);
CollisionMesh->SetNotifyRigidBodyCollision(true);
CollisionMesh->SetVisibility(true);

LaunchBlast = CreateDefaultSubobject<UParticleSystemComponent>(FName("Launch Blast"));
LaunchBlast -> AttachTo(RootComponent);

All appears to align with Ben’s code, so I’m stumped as to why LaunchBlast doesn’t have the ability to add particles. Help.

Yeah, that’s an annoying bug. I believe you can fix it by commenting out the UPROPERTY, rebuilding, and then uncommenting it out and rebuild.

Side note to have a code block indent by 4 spaces or wrap with backticks

Thanks for the reply. Interestingly, when I tried to reopen the project in Unreal, it said it wouldn’t compile and I should recompile manually.

After recompiling manually, I was able to follow the steps you provided and get the particle component.

Just to be clear, you got everything working?

[Jeff_Miller]

yes
