Find the Terrain Width and Height

Questions & Answers

Hi, fellow unity developers :slight_smile:

I wrote a script for a RTS camera that prevents the camera from going off the terrain (when the player moves the camera with WASD / arrow keys, found in another script, not included below).

As you can see, in my code below, I have hardcoded the width and height of the terrain.
I want to be able to automatically detect the width and height of the terrain.

Note: I am very new to Unity and C# so if you know the answer, please provide a complete code not just fragments, ty :slight_smile:

using System.Collections;
using UnityEngine;

public class CameraBounder : MonoBehaviour {

	int minXBound = 50;
	int maxXBound = 50;
	int minZBound = 100;
	int maxZBound = 200;
	int terrainWidth = 500;
	int terrainHeight = 500;

	// Use this for initialization
	void Start () {
	}
	
	// Update is called once per frame
	void Update () {
		Debug.Log("X: " + transform.position.x + " Z: " + transform.position.z);

		if (transform.position.x > terrainWidth - maxXBound) {
			transform.position = new Vector3 ((terrainWidth-maxXBound), transform.position.y, transform.position.z);
		} 
		if (transform.position.x < minXBound) {
			transform.position = new Vector3 (minXBound, transform.position.y, transform.position.z);
		}
		if (transform.position.z > terrainHeight - maxZBound) {
			transform.position = new Vector3 (transform.position.x, transform.position.y, (terrainHeight-maxZBound));
		}
		if (transform.position.z < minZBound) {
			transform.position = new Vector3 (transform.position.x, transform.position.y, minZBound);
		}
	}

}
