Creating a trigger box to slow down an AI Vehicle?

Archived Forums Questions & Answers

I have a vehicle following a path down a road towards a roundabout. I would like the vehicle to slow down and stop before entering the roundabout as if waiting for traffic. I know you can make trigger boxes to slow a cars velocity down, but I’m not at the point where I know what code to use on the trigger box. Any Help would be appreciated. Thank you.

Create a box and turn off it’s mesh. If it has a collider then make sure that its isTrigger box is checked. If it doesn’t have a collider give it one and check the isTrigger box.

Then add a script like this:

To where the line that says:

Destroy(other.gameObject);

will now say:

other.gameObject.YourMovementScript.speed() = int slowerSpeed;

And whenever the car enters the (now invisible box) it will slow down.
