Character rotation smoothing.

[3DModelerMan]

I'm working on making my character rotate when it changes direction. This is my code:

Code: Select all

//Apply rotation
 static irr::core::vector3df rot = getSceneNode()->getRotation();
 
 //Only update when moving.
 if ( m_direction.getLength() != 0 )
 {
  irr::core::vector3df angle = vel.normalize().getHorizontalAngle();
  angle.Y += 180;
  
  //Smooth later
  rot.Y = angle.Y;
 }
	
 getSceneNode()->setRotation(rot);

That snaps it to the direction it's going, but I want it to rotate smoothly the shortest direction. But everything I try produces nasty flickering.

You could interpolate between the curren't angle and the wanted angle.
If you want to do it with vector3d, the class has the function getInterpolated, where d should be (time since rotation start) / (time rotation should take)

The shorter direction thing, the other way is abs(angle-target) and the other way is 360-abs(angle-target)

Thanks, I'll try that.
