RPCs error

[Erik_Reiz]

I was trying to make RPCs functions, but i got some errors.

This is my code

private:
UPROPERTY(Replicated)
FString PCInfo;


UFUNCTION(NetMulticast, Reliable, WithValidation)
virtual void TakeHardware();
UFUNCTION(Server, Reliable, WithValidation)
virtual void SendHardware();

sprintf(Temp, “%llu”, TotalSpace / 1000000);
Temp1 = Temp;
sprintf(Temp, “%llu”, FreeSpace / 1000000);
Temp2 = Temp;

It’s printf not sprintf

[Erik_Reiz]

That’s not the problem.

Hey friend - generally the exited with code 6 error refers to a missing header file or something being missing from the build.cs modules line - did you add something recently without adding its module name ?

[Erik_Reiz]

I got this error after adding server, reliable and netmulticast specifiers to UFUNCTION

[telesphorosgames]

do you need to add _Implementation to the end of your definitions in the cpp file for sendhardware and takehardware?

void APuzzlePlatformsCharacter::TakeHardware()_Implementation
{

I would try that next

[Erik_Reiz]

There’re more errors. Like this one ‘_Implementation’: unknown override specifier

[telesphorosgames]

Sorry for the late response - I actually typed that wrong It should look like this :

void APuzzlePlatformsCharacter::TakeHardware_Implementation()
{

[Erik_Reiz]

For some reason i didn’t get a notification)
I tried this variant, but i still have some errors class
“APuzzlePlatformsCharacter” has no member “TakeHardware_Implementation”
