In game guide pg (follow path and "wait" for the player)

I want to make a small pg in my game, as a guide. This should move throgh the road so the player can follow it and take the right road. But this pg should stop and wait for the player if he remains distant.

How can I do this? is it possible with logic brick?

Too difficult?

Something like crazy taxi?

I’ve found it

Near AND IPO loopstop

The only problem is that, in case the one leaving the other behind is the ball, the guide will stop. But this can me simply “fixed” with the story
