[Plugin] Leap Motion - Event Driven

[getnamo]

@mankindforward;205860

Yes, I’m doing this on two separate computers. Two of everything, connecting over LAN. Movements are replicated properly, meaning Player 1 can move and Player 2 sees the him move. I’ll keep digging but it sounds like this should work. Have you tested this scenario yourself? Or anybody else tried this? Perhaps I’m missing some configuration.

Interesting. I do not have 2 leaps to replicate what you’re doing, but based on my experience with networking you can choose specifically what should replicate and what shouldn’t. You may be doing full actor replication instead of variable replication.

If you use variable replication with hand/finger positions (e.g. AnimBody) then downstream they should affect the 2nd client only as expected. There are various approaches to what information gets updated over a network. A good primer on blueprint networking can be found here: v=TbaOyvWfJE0

Needed your help how could I convert that mouse pointer to down direction and also I don’t want camera to follow that mouse pointer

You probably want to do an raycast originating from the hand’s position in the negative Z axis. This would achieve what you’re looking for

How could we do that Hand alone[Without character attached] for Leap motion.

Already answered earlier.

Hey ,

I just wanted to see if you could give me some direction on what I’m trying to do with your plug in. I want to assign custom functions to basic gestures. I.E. Swiping and rotating an object, pinching to zoom, or controlling the translation of an object by forming a fist and moving it. The goal is to utlize leap motion in showcasing products and having customers interact with it.

I don’t know if there are readily available sources for this, and as a beginner, I sometimes get extremely confused. How should I go about doing this? Where do I start experimenting? Which blueprint are the edits supposed to be done under? If you could give me your opinion as to how to do something similar and tell me the logic behind it I would really be grateful.

Amazing job as always!
Cheers,

You probably want to use the Swipe Gesture recognizer in a similar manner to

See the repo for more detailed documentation.

Hey ,

Thanks for this amazing plugin !

Can you tell me how to use it with C++ code ? (Listener with events, Controller…)

Cheers,
Beunn

It would be similar to how its shown in the hydra plugin video with the main difference that you would add a leap component instead of a delegate subclass (leap plugin doesn’t have this format) and you would set the interface to receive events via A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums.

Hi all,

I have been experimenting with the latest Leap Motion SDK, and the VR widgets in Unity.

Here is the link:

Here is a video I recorded in Youtube: …

Hope we could see this kind of things in UE4 soon with Leap Motion. What do you think ??

Cheers.

These are great things, nothing is stopping you all from adding these kinds of widgets to the plugin, looking forward to seeing these things being tried.

How to put the reality of hand display

The Passthrough effect seen iparra’s video is being worked on however it is not yet ready for the plugin (need to solve 32bit textures first).

Hi All,

I am using a blueprint with Pawn as its parent class. I observe that the hand can be moved over a very limited space in the viewport. What is wrong? How to make the movement cover the whole viewport? Please help.

See this post where we discuss how to change the origin of the leap in default mode.
