Moving Mannequin Right or Left arm using mouse

Development Programming & Scripting

I have been using UE4 for a little less than one year now but still consider myself a new user. This is my first post. Prior to writing this message I did my due diligence and searched here as well as Google search and found this but unfortunately there is no real answer. [“Control Player’s arms with the mouse”][1]

What I’d like to accomplish is to control the right o left arms and hands using the mouse. Pretty much similar to what can be done in the VR sample project except using the mouse. The following is a list of the sample mouse moves I am looking to implement:

Left/Right - Move camera left / right. Already done.
Fwd/Bkwd - Move camera up and down. Already done.

Mouse move with Shift key pressed:

  • Left/Right: Move arm left or right
  • Fwd/Bkwd: Move arm up and down

Left mouse button click

  • Click and hold: Grab item (Make fist or point finger)
  • Release Click: Let go of the item (open hand)

Mouse Move while holding down Ctrl key:

  • Left/Right: Rotate hand left or right
  • Fwd/Bkwd: Move hand up or down

I’ve looked in the Marketplace and can’t find anything close to what I am looking to accomplish. If anyone can point me in the right direction, I’d appreciate it. If I am over thinking what I want to do and there is a better way to do something similar to allow interaction with an object in 3D space, I am all ears.

Thank you for any help!

This is a really interesting idea!

You could probably start by having an IK setup on your characters arms. Here’s some information on getting that started: IK Setup

After setting that up, I think you could get away with having your shift + mouse move the location of the bone at the top of the chain which in turn would move your entire arm.

@rcruzmar did you ever figure this out
