Rotation issue from Unreal to PlayCanvas

[rehman97]

Hello Guys,
First of all sorry i am asking help again on same topic but believe me it is really important to me do this task have been stuck since many weeks.

what i want to do:
I am creating a replay scene basically it is cricket VR game I want to create a replay web platform for user to watch and share their cricket experience to others. I choose playcanvas because i love it.

how i do that:
i have created a rest api server which fetch the unreal engine coordinates. the data which is json format for “Helmet”, “Bat”, “ball” entities with their “rotation” and “location” with the help of entities value, we will lerp means animate. next the data will be fetch in playcanvas.

status of project:
the project look amazing i am getting the values the x, y and z axis converting it then animating it. its complete 80%.

So what the issue Men?
the issue is with “rotation” only and the main rotation problem is with “cricket bet”. you will better get when you watch the video i have played the 3 shots you can compare the result.

here is video

here it is the project link:

here the launch link:

Hi @rehman97!

Editor Bug: Rotating an entity can sometimes flip it

Hey, I’m having a weird issue when rotating entities inside the editor, that sometimes rotating past a certain point, the X and the Z axes flip from 0 to -180, despite me only rotating on the Y axis. Video: Sample project: https://playcanvas.com/project/634129/overview/rotation-bug

Get clean EulerAngles

Hello, I have a small issue with the eulerAngles, that I cannot figure out how to solve without rewriting existing code. I have a script, which requires some rotational values between 0 – 360 and I thought I can simply feed it with the output from the getEulerAngles() function and clamp it to stay between 0/360 instead of -360/360. But then I run into the issue, that the output of the eulerAngle function does some weird voodoo of swapping the rotational values around. Like discussed here: …

Useful pc.Quat functions

I’ve been using a couple of functions that I find particularly handy. Often in my code I need to get just the element of rotation around the Y axis between two things, so I can adjust it. You can’t do this with .getEulerAngles().y because that will suddenly flip based on the rotation (the x, z elements would also flip). What you need is a stable twist around an axis that won’t suffer these effects - enter this.entity.getRotation().twist(pc.Vec3.UP) which returns the +/- angle around that axis…

thanks @Albertos yeh i have also visited that links even ask them as personal. but still issue is same.

i think the issue will be solved with quaternion but i dont no about it trying to study if you find something it would be my pleasure.
