Compiler error C3493: 'func' cannot be implicitly captured because no default capture mode has been specified

Question

Can you help me resolve this compiler error?

template
static void ComputeGenericDropCount(function func)
{
    T::ForEach(         


        

Answer 1

You need to specify how to capture func into the lambda.

[] don't capture anything

[&] capture-by-reference

[=] capture-by-value (copy)

T::ForEach([&](T *what) {

I'd also recommend that you should send func by const reference.

static void ComputeGenericDropCount(const function<void(Npc *, int)>& func)
