Argument for class template ... missing

[wanton flare]

Intellisense says "Argument for class template CollisionBody is missing"

class CollisionBody : public Actor{
public:
    std::unique_ptr<ShapeBase> shape;

    olc::vf2d velocity = {0.0f, 0.0f};
    olc::vf2d acceleration = {5000.0f, 5000.0f};
    olc::vf2d collision_normal = {0.0f, 0.0f};
    
    template<typename tShape, typename ...tArgs>
    void SetShape(tArgs ..._args){
        auto l_shape = std::make_unique<Shape<tShape>>(tShape(_args...));
        l_shape->callbacks.push_back(
            std::function<void(Shape<tShape>* _shape)>([](Shape<tShape>* _shape) -> void {
                System::Get().Func(_shape);
            })
        );

And I can't just compile this and see if it says something because this is a piece of something that takes more time to rework. Plus, interestingly it's not raising any issues in my test file, which compiles successfully. I think it's complaining about the lack of a template<class ...> above the class declaration, but I'm not TRYING to make a template class. So what is happening here?

Aaaand there is more.

CollisionBody(olc::vf2d _position) : Actor(_position){
        //if(Engine::Get().vsync) acceleration = {0.1f, 0.1f};
    }

Here's the constructor for example. Not spotting any issues with it.

Maybe I should just ignore this and keep cooking. Maybe it's just intellisense messing with me.

A) Did you compile with -Wall -Wextra?
B) Did you try to restart your IDE?
C) Did you declare CollisionBody in a header file where it maybe is templated?

D) Can you send the full error?

[wanton flare]

I sent the full error. I only have an intellisense error, I literally can't compile the full thing, I stated that very clearly.
I do have a test file though, maybe I can share that, because it does not give me the same error there.

I forgot how to use pastebin.

Honestly I forgot that, but could you make a MRE (minimum reproducible example)?

[wanton flare]

I go to pastebin, paste the thing and think, wait, what do I do now?

[wanton flare]

The MRE is not the problem right now, the problem is that I don't know how to share my MRE

[wanton flare]

And it's not a TRUE MRE, because the thing contains the same class, except it works.

[modern ruin]

Btw, what about C?

Did you declare CollisionBody in a header file where it maybe is templated?

[wanton flare]

There we go. But anyway this is not an MRE, it's just the same class, but I'm not getting the error.

*And also what about B? Did you try to simply restart your IDE? Sometimes that fixes it

[wanton flare]

I do not understand the question.

[wanton flare]

Did not work.

[modern ruin]

Ah yeah, that doesn't make any sense either.
Sorry, I'm not 100% sober rn

Is Actor a templated class?

[wanton flare]

It's not, and Actor is the highest in the class hierarchy.

[sleek trench]

Are you including any other libraries which might also be defining CollisionBody? If you just write CollisionBody on it's own before where you defined it can you right click and "jump to declaration"?
Also if you're using Visual Studio it's worth closing, going into windows explorer and under view selecting "show hidden files", then in the project folder delete the .vs folder, then reopen the project.

[wanton flare]

No. I think it was just intellisense messing with me, it disappeared eventually
