Question Change gameobject scale based on how close player is to the gameobject?

I need an algorithm for this for my game and I can't seem to figure it out. When my player gets closer to the gameobject, the size of the object should decrease. When the player gets further away, the size of the object should increase. In the end, what I am actually trying to do is have it so that the gameobject is always touching the player (by getting larger or smaller).

BONUS: If I can also make the gameobject rotate to always face the player that would be a plus.

 

I would calculate the vector3.distance between the player and the gameobject then increase/decrease the scale based on the number you get. It would take some tweaking after that but should put you on the right path. As for making the gameobject always rotate towards the player that's actually quite easy, use transform.lookat .

 

Are you trying to achieve an effect like this?

 

Thanks. I'll try this tonight.

 

Not exactly, but that is really cool!
