"SpawnActor failed because no class was specified"
Hello, I have this problem since last lecture. Fixed it with blueprint. But now when I try add this in Projectile.cpp
ProjectileMovement->SetVelocityInLocalSpace(FVector::ForwardVector * Speed);
ProjectileMovement->Activate();
editor crash.
I tried to fix this class error, even copied files from course, and nothing work.
did you attach header file in Tank.cpp? #include “Projectile_C.h”
I had the same problem! When we changed the all the scripts to EditDefaultsOnly from EditAnywhere it changed some of the blueprints. Make sure the Projectile BP in tank is filled in. Just in case check the other blueprint filled members as well.
good luck
This is how I did it.
// Spawn a projectile at the socket location of the barrel
auto SocketLocation = Barrel->GetSocketLocation(FName("Projectile"));
auto SocketRotation = Barrel->GetSocketRotation(FName("Projectile"));
FActorSpawnParameters SpawnInfo;
GetWorld()->SpawnActor<AProjectile>(ProjectileBlueprint, SocketLocation, SocketRotation, SpawnInfo);
You need to #include the Projectile.h header file and the TankBarrel.h header file into Tank.cpp
And make sure you add the Projectile_BP in the Projectile Blueprint option we created in Tank_BP under Setup. Like this…
Scratch that, you don’t need FActorSpawnParameters
// Spawn a projectile at the socket location of the barrel
auto SocketLocation = Barrel->GetSocketLocation(FName("Projectile"));
auto SocketRotation = Barrel->GetSocketRotation(FName("Projectile"));
GetWorld()->SpawnActor<AProjectile>(ProjectileBlueprint, SocketLocation, SocketRotation);You my good friend are an absolute STAR!

You snippet of code worked wonders, if I ever need advice, I’ll be your agent any day!!!
