How to move an object to a selected object by clicking?

Hi,

I was recently replaying Spore, and I saw that in the space stage when you have control of the space ship that you can move a "star" or a "planet". I'm having trouble doing this, I have a Click to Move script (from BurgzergArcade's tutorial).

How do I make my player game object move to the location of the planet game object? via selecting the planet.

 

do you mean this one?

lines 53-54 need to be changed.

the raycast needs to detect the "hitting a planet"

look at the example for

http://docs.unity3d.com/ScriptReference/Physics.Raycast.html
(note you have to provide a distance if you want to use a layermask, they're both numbers and you can't "skip over" an optional parameter when you want to provide an override for another optional parameter later in the paramlist, if you do try the layermask will be implicitly cast to a float and used as the distance )

you can then use the RaycastHit to get the transform that is being hit and get a position to move to from that
