Well, this is what I did, I placed an empty at the center of the scene, I did an ipo of 40 frames on location of the empty to have an impact of about 2 seconds, then I tracked the camera to the empty. If I press NumPad0 and then Alt A it works great.
Then in the game engine when I initialize all the things in the scene I also put an EditObject actuator on the camera, I set it to Track to and I specified the empty.
When it comes the time for the impact I change with a script a property of the empty which trigger the ipo for the empty
But nothing happens
Please help me!
