Ue4 Move Actor By Mouse Upgrade To A

To get the best possible experience using our website we recommend that you upgrade to a newer version or other web browser.

In a UMG scenario I would set the background to SelfHitTestInvisible to allow mouse events to fall thru the transparent area of the widget.

Setting this on the NoesisView widget does not have the same effect.

I have also tried setting the root component in my xaml user control (a Grid) to BackgroundTransparent and also Backgroundx:Null.

I have put together a small demo project based on the Login sample to show what is going on.

Ue4 Move Actor By Mouse Code Changes In

I think Im close to a solution, but I couldnt delay pushing a new version for longer, since there were some code changes in the latest SDK versions that required it.

I got it working with the events getting to the player controller if the element doesnt have a background (Transparent is a background, it has to have no background at all).

Im going to commit this, along with other changes, later today.

Certain events work, like clicks, but mouse over events dont.

Im working on a solution that Ill commit to GitHub as soon as possible.

Hi Jason, Jake has discovered some problems with the current implementation.

The bad news is that a proper fix for this requires an Engine patch.

Ill contact Epic with a pull request, because I think this change is necessary for anyone that wants to implement custom controls with hover over behavior and non rectangular shape.

The first bit of good news is that the change is relatively simple, so Ill attach the patch, but Ive already found that buttons dont behave correctly with it.

The button widget is fixed in the patch, but there may be other widgets that behave incorrectly as well.

Also, this can only be done if you have the source code from GitHub, and not with Epic Games Launcher versions.

It involves a new function I just committed to GitHub, and all you have to do is to override the function IsInViewportClient in your player controller like this: Code: Select all bool IsInViewportClient(UGameViewportClient ViewportClient) const override.

Its possible the new function requires some tweaking, but hopefully this will unblock you and allow you to keep working.

Heres the Engine code patch, in case you want to try this: Code: Select all diff --git aEngineSourceRuntimeSlatePrivateFrameworkApplicationSlateApplication.cpp bEngineSourceRuntimeSlatePrivateFrameworkApplicationSlateApplication.cpp.
