Component of new entity that was created by entity->Instantiate() has a pointer to original entity

[Dreikblack]

Looks like a component of new entity that was created by entity->Instantiate() has a pointer to original entity.

Several months it worked fine. Maybe something went wrong when public entity pointer was replaced by GetEntity() method.

Steam beta branch.

#include "UltraEngine.h"
#include "ComponentSystem.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1200, 800, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world
    auto world = CreateWorld();

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a camera
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 0, -3);

    //Create a light
    auto light = CreateBoxLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    //Create a box
    auto box = CreateBox(world);
    box->SetPosition(1, 1, 1);

    auto component = box->AddComponent<Mover>();
    component->rotationspeed.y = 45;

    auto newBox = box->Instantiate(world, true, true);
    newBox->SetPosition(2, 2, 2);

    auto componentTest = newBox->GetComponent<Mover>();

    Print("first box pos x:");
    Print(box->GetPosition().x);
    Print(component->GetEntity()->GetPosition().x);
    Print("second box pos x:");
    Print(newBox->GetPosition().x);
    Print(componentTest->GetEntity()->GetPosition().x);

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        world->Update();
        world->Render(framebuffer, false);
    }
    return 0;
}

Thanks, that was an easy fix. I'll have an update up later today.

[Josh]

I will upload an update tomorrow. It's a little bit late in the day and I'd rather do it when there are many hours left.

No fix in newest update

[Josh]

I'm going to investigate this navmesh thing and see if it's an easy fix I can fit in before I update the lib...

[Josh]

It's fixed on the standalone now. Verified with this example:

#include "UltraEngine.h"
#include "Components/Motion/Mover.hpp"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Create a world
    auto world = CreateWorld();

    //Create a box
    auto box1 = CreateBox(world);
    auto component1 = box1->AddComponent<Mover>();

    auto box2 = box1->Instantiate(world, true, true);
    auto component2 = box2->GetComponent<Mover>();

    Assert(component1->GetEntity() != component2->GetEntity());

    return 0;
}

Thanks! Will be update available in Steam today?

[Josh]

I thought you were using the standalone?

[Dreikblack]

No, in my region Paypal and Visa cards does not work nowadays so Steam is the only way to buy Ultra and i did that.

I bought few months of Ultra sub before with fan Quake league reward money that i requested to send to me as a gift at this web-site.

[Josh]

okay, it's live on steam now, on the beta branch
