Render crash if reCreateWorld same world

[Dreikblack]

Default start map from template

Happens after first enter press:

Comment in loop "world = CreateWorld();" to get another render crash (RecordDraw) but it's not consistent and may take several attempts (Andy have this issue i believe):

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

using namespace UltraEngine;

int main(int argc, const char* argv[])
{

    RegisterComponents();
    auto fiplugin = LoadPlugin("Plugins/FITextureLoader");
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280 * displays[0]->scale, 720 * displays[0]->scale, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);
    auto framebuffer = CreateFramebuffer(window);
    auto world = CreateWorld();

    WString mapname = "Maps/start.ultra";
    auto scene = LoadMap(world, mapname);

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {

        if (window->KeyDown(KEY_ENTER)) 
        {
            world = CreateWorld();
            scene = LoadMap(world, mapname);
        }
        world->Update();
        world->Render(framebuffer);

    }
    return 0;
}

Awesome, thank you, I can produce this error very easily. Now to solve it...

[Josh]

I was able to easily fix this and will have an update for you later today. Thanks for your help!

One crash fixed and 2nd still happens if you comment out one line that i mentioned in first post. Just to make sure you know what i mean i post code it again with commented line

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

using namespace UltraEngine;

int main(int argc, const char* argv[])
{

    RegisterComponents();
    auto fiplugin = LoadPlugin("Plugins/FITextureLoader");
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280 * displays[0]->scale, 720 * displays[0]->scale, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);
    auto framebuffer = CreateFramebuffer(window);
    auto world = CreateWorld();

    WString mapname = "Maps/start.ultra";
    auto scene = LoadMap(world, mapname);

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {

        if (window->KeyDown(KEY_ENTER))
        {
           // world = CreateWorld();
            scene = LoadMap(world, mapname);
        }
        world->Update();
        world->Render(framebuffer);

    }
    return 0;
}

I updated pro build on Steam this morning. You sure this is happening with the latest build?

[Dreikblack]

Yes

[Josh]

Using a new project and the current beta branch on Steam, I copied this code into the main.cpp file, ran it, pressed the enter key about 10 times to reload the map, with no errors.

[Dreikblack]

Well, it's very inconsistent i guess. Can only suggest to try again

Steam beta, latest update, even created new project for latest test - 4th attempt (enter press) caused a crash, st and 2nd after that.

 

[Josh]

Does this still happen if you remove all lights from the scene?

[Dreikblack]

No, with removed lights it does not. Tried return lights - happens again right away.

[Dreikblack]

This issue seems to be gone with Vulkan

[Josh]

Do you mean OpenGL?

[Dreikblack]

I meant Vulkan is gone just like issue and vice versa
