How i can grab n Object based on BP_PickupCube with two hands?

I Want to Hold a Billiard Stick and if i hold with two hand allow only move forwards and backwards!

JUDGE_DREDD_VR · February 4, 2018, 3:33am

No Ideas for my question?

Attach it to one hand (right hand should be a master hand for a billiard cue) and rotate in a direction of second hand in Tick. There is no other way.

JUDGE_DREDD_VR · February 4, 2018, 6:28am

Have you a example how i can make this?

YuriNK · February 4, 2018, 8:41am

I only have C++ class, and it isn’t finished yet. But your task is easier.

attach to fist hand
when player is trying to grab the cue with a second hand - enable tick
in tick
a. calculate required rotation using MakeRotFromXY(
first param: second hand location - location at the cue of the main hand attachment
second param: Up vector at location at the cue of the main hand attachment)
b. Apply this rotation to cue (SetWorldRotation).

Can you show me this in Blueprint a Image?

YuriNK · February 4, 2018, 12:39pm

And of course, you cue mesh mush have X as a forward axis for this setup.

JUDGE_DREDD_VR · February 4, 2018, 3:53pm

How you can reference MContrroller Left and Right in a Actor BP? i can only Reference MotionControllerBP!

And i cant find SetActorRotation for my Mesh!

YuriNK · February 5, 2018, 7:12am

MotionControllerBP blueprint in the Unreal VR Template has motion controller component inside.

JUDGE_DREDD_VR · February 5, 2018, 7:47am

? Your MController Left this is a Variable with reference to? i can only find Motion Controller but not Left or Right And i cant find SetActorRotation

JUDGE_DREDD_VR · February 5, 2018, 9:11am

I mean this

I have The Motion Controller but specific The left and right hand i have only in Pawn BP

JUDGE_DREDD_VR · February 9, 2018, 8:58am

Can you please explain this to me?

Enter_Reality · February 9, 2018, 9:28am

Take a look at Mitch VR Content Example, there is already a setup for a two hand grab of an object, so you can see what’s going on there and replicate it accordingly

JUDGE_DREDD_VR · February 9, 2018, 9:49am

I Have the Plugin but i use 4.15! in 4.15 is not the Two Hand Setup

Enter_Reality · February 9, 2018, 10:16am

Download 4.18, check the VR Content Example, then apply the same setup to what you’re developing.

JUDGE_DREDD_VR · February 9, 2018, 10:54am

OK, I mixed it up with something else have now 4.15 Version,
but somehow I can not figure out how it works it’s confusing! and its not Standart VR Pawnd and Controller from Epic Template.

mordentral · February 9, 2018, 2:31pm

The “standard” VR pawn and controller is woefully underdeveloped and in need of extension. You shouldn’t limit your self to its framework.

JUDGE_DREDD_VR · February 9, 2018, 2:42pm

I use the VR Pawn from your plugin but 4.15

Unfortunately, I just can not get it with the 2 hand grip

JUDGE_DREDD_VR · February 10, 2018, 8:30am

So can someone help me implement that?

JUDGE_DREDD_VR · February 12, 2018, 3:09pm

OK i integrade the Mitch VR Content Example two handed to my VR Pawn and work fine
now i want next step how i can Lock my Billiard Cue? so that I can only move the Billiard Cue in one direction? And Block all Other Direction and Rotaions?
