Keyboard input don't work in ue 4.13 without previous mouse action

I tried to run the sedan vehicle example in ue 4.13 and the keyboard axis inputs don´t work, but if you put a mouse input and execute the mouse action before touch the keyboard then works properly.

Just call the BP function “Set Input Mode Game Only” it take the Player Controller as input, you can call it on event begin play in the level blueprint or in your player character’s blueprint

Hey vixxvix-

This is a known issue that was reported here: Unreal Engine Issues and Bug Tracker (UE-13053)

As Night Watcher mentioned, you can use the Set Input Mode Game Only on Begin Play to workaround this initial focus issue.

Cheers
