The display position of the text in DrawDebugString is affected by the scale of the display.
Should refer to the Project() of DebugCanvas (not Canvas).
- Suggest Code
void AHUD::DrawDebugTextList()
{
// ...
// don't draw text behind the camera
if ( ((WorldTextLoc - CameraLoc) | CameraRot.Vector()) > 0.f )
{
// Project with DebugCanvas
// FVector ScreenLoc = Canvas->Project(WorldTextLoc);
FVector ScreenLoc = DebugCanvas->Project(WorldTextLoc);
TextItem.SetColor( DebugTextList[Idx].TextColor );
TextItem.Text = FText::FromString( DebugTextList[Idx].DebugText );
TextItem.Scale = FVector2D( DebugTextList[Idx].FontScale, DebugTextList[Idx].FontScale);
DebugCanvas->DrawItem( TextItem, FVector2D( FMath::CeilToFloat(ScreenLoc.X), FMath::CeilToFloat(ScreenLoc.Y) ) );
}
// ...
}
Result:
The debug text is displayed in a location away from the Actor.
Expected:
The debug text is displayed in the Actor's location.
