I’ve made two methods to trigger lmb pressed/released and obviously a bool to know the “fake”. I’ve ended up doing a less than elegant, but working solution for this: My chosen mouse pan key is a keyboard key. That Input mode just refuses to take any axis input from the mouse unless lmb or rmb are down. It would be a bit silly if I didn’t define axis mappings now, would it? Have a look – it may be something you are looking for: void MyPlayerController::SetInputModeGameOnly( It is not universal but suits my needs perfectly. I made a small helper function in my player controller class. And if you need other values you will have to initialize input mode manually. You see, that calling this method just creates a new object with no arguments and that is equal to setting Default Viewport Mouse Capture Mode to “Capture Permanently”. Open WidgetBluprintLibrary.cpp and the method UWidgetBlueprintLibrary::SetInputMode_GameOnly And if it is not your default value, your game will run not as you expect. The problem, however, is that Set Input Mode Game Only resets this option to “Capture Permanently” value. You will see that Default Viewport Mouse Capture Mode may have the following possible values:Ī default value could be “Capture Permanently Including Initial Mouse Down” or another one. Let’s examine Project Settings -> Input section of a UE4 project.
Now the reason why Game Only mode did not work is that the mode is not exactly the default mode of UE4. I tried using Set Input Mode Game and UI but that was not exactly what I wanted. When I was implementing a menu for my game I faced a problem similar to this one: Īfter quitting the menu and switching back to Game Only mode, I had to click twice or double click in order to get the mouse back to work. It is Set Input Mode Game Only and how it is different from the UE4 default input mode. It covers pretty much everything you need to know.
