My boat goes through the terrain, how do I stop this?

[Tornado_Gaming]

I have programmed my boat to move, and it happily sails around, but it can go through the islands I have made out of the terrain. I have put a box collider around it, but that didn’t help. If my code needs to be changed, please tell me. This is my code:

var rock_isGoingToRight = true;
var rock_Amount = 0;
var isRockingBackwards = true;
var isCollided = false;

function Update() 
{
	if((Input.GetKey("up") || Input.GetKey("w")) && isCollided === false) {
		transform.Translate(Vector3.right * (Time.deltaTime*40)); 
	}
	
	if(Input.GetKey("right") || Input.GetKey("d")) {
		transform.Rotate(Vector3.forward * (Time.deltaTime*10)); 
	}
	
	if(Input.GetKey("left") || Input.GetKey("a")) {
		transform.Rotate(Vector3.back * (Time.deltaTime*10)); 
	}
	if(rock_isGoingToRight === true) {
		transform.Rotate(Vector3.right * Time.deltaTime);
		rock_Amount++;
		if(rock_Amount > 90) {
			rock_isGoingToRight = false;
		}
	} else {
		transform.Rotate(Vector3.left * Time.deltaTime);
		rock_Amount--;
		if(rock_Amount < -90) {
			rock_isGoingToRight = true;
		}
	}
}

function OnCollisionEnter(theCollision : Collision) {
	isCollided = true;
}

Try setting a Terrain collider to the terrain. then setting the terrain data to point to the terrain you are using…

[tanoshimi]

1.) Does your terrain have a collider on it too?

2.) On line 8, try changing isCollided === false to isCollided == false (or even just !isCollided)
