About onEndCollision ? (Sloved!)

function init(...)
{
   ...

   %this.CollisionShapeId = %this.owner.createCircleCollisionShape( %this.owner.FireRange );
   if( %this.CollisionShapeId == -1 )
   { 
      return false;
   }
   
   %this.owner.setCollisionShapeIsSensor( %this.CollisionShapeId, true );

   ...
}

function ObjectBehaviorHotArea::onCollision( %this, %sceneObject, %collisionDetails )
{
   echo( "onCollision: " @ %this @ " # " @ %sceneObject @ " # " @ %collisionDetails );
}

function ObjectBehaviorHotArea::onEndCollision( %this, %sceneObject, %collisionDetails )
{
   echo( "onEndCollision: " @ %this @ " # " @ %sceneObject @ " # " @ %collisionDetails );
}

output:

onCollision: 1240 # 1247 # 0 1
onEndCollision: 1240 # 0 1 #

%sceneObject was missing in onEndCollision?

I need to confirm who leave my area, help me :)
