I download strategy game from market place and when I run it from unreal editor I have does not work correctly AStrategySpectatorPawn::OnMouseScrollUp() and AStrategySpectatorPawn::OnMouseScrollDown().
After first ZoomIn of camera to ground triggered method OnMouseScrollUp(), then I’m ZoomOut camera from ground, method works OnMouseScrollDown(). But immediately after end ZoomOut camera, it starts itself closer (ZoomIn) to ground to maximum.

I have appointed to perform zoom in and out on keys on keyboard, and this effect does not occur, which means that code is all right.

InputComponent->BindAction("ZoomOut", IE_Pressed, this, &AStrategySpectatorPawn::OnMouseScrollUp);

InputComponent->BindAction(“ZoomIn”, IE_Pressed, this, &AStrategySpectatorPawn::OnMouseScrollDown);

OS X 10.9.5, magic mouse.

Unreal Engine 4.4.3. This behavior has been observed also in previous versions.

Hey PravProduct,

This is a known issue with scrolling devices that do not scroll incrementally like a mouse wheel, including but not limited to Magic Mouse. We have a bug report in our database (TTP# 332344) and developers are considering options to address issue.

Thanks for your report! I will let you know when I see an update on it.
