Falling Blocks
Part of the Unity Scripting Basics section of Coddy's Unity journey. Lesson 61 of 67.
Challenge
MediumNow blocks fall from the sky. Keep the steering from the last lesson, and add to Runner:
- Three fields the Inspector fills:
blockPrefab(aGameObject: the scene gives it the Block prefab),spawnEvery(1) andfallSpeed(5). - A
List<GameObject>namedblocksthat remembers every block you spawn. - Every
spawnEveryseconds, spawn a Block at a random x between-laneEdgeandlaneEdge, at y = 10 and z = 0, and add it toblocks. - Every frame, move every block in
blocksdown atfallSpeedunits per second.
The blocks cannot hurt the runner yet. Press Play and watch them fall, then Check.
Try it yourself
using UnityEngine;
public class Runner : MonoBehaviour
{
[SerializeField] private float speed = 6f;
[SerializeField] private float laneEdge = 4f;
void Update()
{
Vector3 p = transform.position;
p.x += Input.GetAxisRaw("Horizontal") * speed * Time.deltaTime;
p.x = Mathf.Clamp(p.x, -laneEdge, laneEdge);
transform.position = p;
}
}
