Computer Target

I'm making a level with a planet destroyer. I have the planet's only engaged by flag set so that the planet is only attacked by the PD.

My problem is how to make it so that the planet destroyer's target will always be the planet and never change. I tried set destination but it doesn't work too well.

There's an initial object flag that you can set, "static target" or something.
