Hi guys, i read some posts about it, but could not understand how to solve this problem.

.h
UFUNCTION() void blockClicked (UPrimitiveComponent* ClickedComp);

Last string error:

.cpp
    void AMyBox::blockClicked(UPrimitiveComponent* ClickedComp)
    {
       randColor();
    }
    
    void AMyBox::createBlock()
    {
       DummyRoot = CreateDefaultSubobject<USceneComponent>(TEXT("Dummy0"));
       RootComponent = DummyRoot;
       class UStaticMesh* BlockStatickMesh;
       BlockStatickMesh = ConstructorHelpers::FObjectFinderOptional<UStaticMesh>(TEXT("StaticMesh'/Game/MyBlock.MyBlock'")).Get();
       BlockMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("BlockMesh0"));
       BlockMesh->SetStaticMesh(BlockStatickMesh);
       TempMaterial = ConstructorHelpers::FObjectFinderOptional<UMaterial>(TEXT("Material'/Game/Blue.Blue'")).Get();
       BlockMesh->SetMaterial(0, TempMaterial);
       BlockMesh->AttachTo(DummyRoot);
       BlockMesh->OnClicked.AddDynamic(this, &AMyBox::blockClicked);//there is no instance //of function template matches the argument list.
    }

Hi,

As of UE 4.12, your event handler will need to be defined to take an extra FKey parameter:

“OnClick/OnReleased events now have an additional argument that specifies which key was responsible for the event.”

Hope this helps,

Steve

Thanks, you pointed me in the right direction.
If someone will face with a similar problem:

.h

UFUNCTION() void blockClicked(UPrimitiveComponent* ClickedComp, FKey ButtonPressed);

.cpp

UFUNCTION() void AMyBox::blockClicked(UPrimitiveComponent * ClickedComp, FKey ButtonPressed)
{
randColor();
return UFUNCTION() void();
}

void AMyBox::createBlock()
{
	DummyRoot = CreateDefaultSubobject<USceneComponent>(TEXT("Dummy0"));
	RootComponent = DummyRoot;
	class UStaticMesh* BlockStatickMesh;
	BlockStatickMesh = ConstructorHelpers::FObjectFinderOptional<UStaticMesh>(TEXT("StaticMesh'/Game/MyBlock.MyBlock'")).Get();
	BlockMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("BlockMesh0"));
	BlockMesh->SetStaticMesh(BlockStatickMesh);
	TempMaterial = ConstructorHelpers::FObjectFinderOptional<UMaterial>(TEXT("Material'/Game/Blue.Blue'")).Get();
	BlockMesh->SetMaterial(0, TempMaterial);
	BlockMesh->AttachTo(DummyRoot);
	BlockMesh->OnClicked.AddDynamic(this, &AMyBox::blockClicked);
}
