Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Mouse cursor show/hide issue

I'm trying to make 3d person character go to free-look mode with RMB pressed. When starting an app I'm able to hold RMB and rotate camera as far as I want (no limit).

 // Handle Mouse X
 void AMainCharacter::Turn(float Value)
     if ((Controller != NULL) && (Value != 0.0f) && bIsMouseLookMode)
 // Handle Mouse Y
 void AMainCharacter::LookUp(float Value)
     if ((Controller != NULL) && (Value != 0.0f) && bIsMouseLookMode)
 // Handle RMB is pressed
 void AMainCharacter::OnStartMouseLook()
     bIsMouseLookMode = true;
     APlayerController* MyController = GetWorld()->GetFirstPlayerController();
     MyController->bShowMouseCursor = false;
     MyController->bEnableClickEvents = false;
     MyController->bEnableMouseOverEvents = false;

 // Handle RMB is released
 void AMainCharacter::OnStopMouseLook()
     bIsMouseLookMode = false;
     APlayerController* MyController = GetWorld()->GetFirstPlayerController();
     MyController->bShowMouseCursor = true;
     MyController->bEnableClickEvents = true;
     MyController->bEnableMouseOverEvents = true;

However, once I show mouse cursor it can't leave viewport area, so I can rotate my camera for a very limited degrees, even if I hide cursor again.

What I'm doing wrong? Is there any simple way to toggle mouse-look/mouse-click mode? Any help/advise is greatly appreciated.

For your question:


However, you probably run into the same problem there; you hit the windows screen edge and can't get anymore inputs from the mouse after that.

To solve the issue, you might give this a try (using your variable MyController here):

FInputModeGameOnly GameMode;         

This SHOULD give you inputs even when you are at the edge of the screen.
