World editor Axis Gizmo bug fix

Hi all,

Here is a bugfix for the World Editor's axis gizmo.

Updating world editor "axis gizmos"

This is from a thread a while back, but I didn't see it posted to the bugs section, so I want to make sure people know about it, and hopefully Ben or someone can stick it in the HEAD. I"ve been using it in my build for a number of months and haven't had any problems.


The culprit is in WorldEditor::collideAxisGizmo(...) in worldeditor.cc
Change this:

bool WorldEditor::collideAxisGizmo(const Gui3DMouseEvent & event)
{
   //...

   // get the projected size...
   SceneObject * obj = getControlObject();
   if(!obj)
      return(false);

   //
   Point3F camPos;
   obj->getTransform().getColumn(3, &camPos);

   //...

To this:

bool WorldEditor::collideAxisGizmo(const Gui3DMouseEvent & event)
{
  // ...

   // get the projected size...
   GameConnection* connection = GameConnection::getServerConnection();
   if(!connection)
      return false;
   
   // Grab the camera's transform
   MatrixF mat;
   connection->getControlCameraTransform(0, &mat);

   // Get the camera position
   Point3F camPos;
   mat.getColumn(3,&camPos);

   //....
