[Documentation] Is entity.quaternion a Quat or Vec3?

[beo6]

In the Documentation quaternion is documented as a entity attribute. However it has Vec3 as Type?

Is that really correct?

 

Also i wasn't successful even getting the quaternion value of an entity:

System:Print("entity quaternion:"..self.entity.quaternion:ToString())

The quat class is not exposed to Lua because it is only used for internal rotations. I've removed that member from the documentation.

[beo6]

wait wait.

 

its ok when you remove the attribute of the entity.

 

But removing the whole Quat class is a bit too much. And also it seems to work creating a Quat in lua.

And how are we supposed to make something like this without a Quat?

Well, I used the quat class in one place in the FPS Player script:

self.carryrotation = Transform:Rotation(pickInfo.entity:GetQuaternion(true),nil,self.camera)

 

Since I used it, that means it is part of the official supported API and it should be documented.

So after 5 months it is still not documented. Maybe time to ..

5 Months? Which Year do you live in?

[Roland]

Oh my good. It was even worse. Its one year and five months

[Josh]

Entity:SetQuaternion, Entity:GetQuaternion, and Transform:Rotation() are the only relevant commands.

[beo6]

1. Entity:SetQuaternion is not documented
   
2. Entity:GetQuaternion is not documented
   
3. that Transform:Rotation() accepts Quaternions is not documented.
   

i guess these are the points from Roland.

[Josh]

I am saying these are not very useful or important.

[beo6]

then either no one want to align stuff to the terrain like here:

http://www.leadwerks.com/werkspace/topic/8487-question-about-physic/page__st__20#entry66616

 

or i am just too stupid to find the Leadwerks own function to do that.

 

 

I really hope it is the second option.

[Josh]

You have a point that Slerp() can be useful.

Okee-dokee, here it is:
