Re: rotate a crate around me when i Turn

Just a question

How did you get characterToWorld ? It is worldToCharacter.inverse() ?

character who react only with gravity

Hi, I have a character and I want that he react to gravity (so there is Collision AND Physics activated on him. That's OK) but I don't want that he moved when an objet or another character touch him. So I want collision on him, so the other entity couldn't pass throught him (that's OK). I Want the r...

I want to know if i'm picking front face or back face

Hi,

I use Bullet for picking and Ogre3d for rendering. I have 2 Questions:

1) If I have a double-sided plane and if I pick it I want to know if I pick front face or back face. It is possible to do that ?
2) How can I know wich subEntities or SubMesh i am picking ?

thx

what is the unit of measure of setWalkDirection() ?

Hi, My question is simple what is the unit of measure of function setWalkDirection() of btKinematicCharacterController ? (meters, centimeters, inch, Foot,...) ? I'm french so I want to work with meters For exemple If I want to move forward to 5 meters what I have to put like paramaters ?? Thanks ++

To know when Character is sliding a slope

Hi

I'm wondering how to know when a CharacterController is sliding a slope of a terrain and how to calculate the distance of sliding/falling.

thanks

Re: How to know if my Character go up or go down a slope ?

I found a solution.

Code: Select all

Ogre::Vector3 dir = PJ->mNode->getOrientation() * Vector3::UNIT_Z;
			Ogre::Radian q = Ogre::Vector3(dir).angleBetween(Ogre::Vector3(point.m_normalWorldOnB));
         
			Ogre::Real rotation =q.valueDegrees()-90 ;

Re: How to know if my Character go up or go down a slope ?

I tried

Code: Select all

Ogre::Quaternion q = Ogre::Vector3(point.m_positionWorldOnA).getRotationTo(Ogre::Vector3(point.m_normalWorldOnB));
			
float rotation =q.y ;
But it doesn't seem to work.
