Context not resizing correctly

[bandrewk]

Hello,

 

the active context is not resizing correctly when changing the window layout without rendering a world.

 

Resizing while rendering a world:

 

Resizing without rendering a world:

 

Example code:

 

bool App::Loop()
{
//Close the window to end the program
if (window->Closed()) return false;

if (window->KeyHit(Key::J))
{
window->SetLayout(window->GetX(), window->GetY(), 1920, 1080);
}
if (window->KeyHit(Key::K))
{
window->SetLayout(window->GetX(), window->GetY(), 1024, 800);
}
//Press escape to end freelook mode
if (window->KeyHit(Key::Escape))
{
if (!freelookmode) return false;
freelookmode=false;
window->ShowMouse();
}

//if (freelookmode)
//{
// //Keyboard movement
// float strafe = (window->KeyDown(Key:) - window->KeyDown(Key::A))*Leadwerks::Time::GetSpeed() * 0.05;
// float move = (window->KeyDown(Key::W) - window->KeyDown(Key::S))*Leadwerks::Time::GetSpeed() * 0.05;
// camera->Move(strafe,0,move);
// //Get the mouse movement
// float sx = context->GetWidth()/2;
// float sy = context->GetHeight()/2;
// Vec3 mouseposition = window->GetMousePosition();
// float dx = mouseposition.x - sx;
// float dy = mouseposition.y - sy;
// //Adjust and set the camera rotation
// camerarotation.x += dy / 10.0;
// camerarotation.y += dx / 10.0;
// camera->SetRotation(camerarotation);
// //Move the mouse to the center of the screen
// window->SetMousePosition(sx,sy);
//}
Leadwerks::Time::Update();
//world->Update();
//world->Render();
context->SetColor(0, 0, 0, 1);
context->Clear();

context->SetColor(1, 1, 1, 1);
context->SetBlendMode(Blend::Alpha);
context->DrawText("10x10", 10, 10);
context->DrawText("100x100", 100, 100);
context->SetBlendMode(Blend::Solid);
context->Sync(false);

return true;
}

 

Comment / Uncomment the world update and rendering and press J and K a few times to resize.

That's interesting. There's not any command in the loop that recalculates the orthogonal projection when the context changes size.

You can add this after the Sync() call, and in the next build it will just work automatically without this code:

    GraphicsDriver::GetCurrent()->projectionmatrix.Ortho(0, context->GetWidth(), 0, context->GetHeight(), -1, 1);
   glViewport(0, 0, context->GetWidth(), context->GetHeight());
