如何解决按程序创建 2d 自上而下赛道的最佳方法
我正在尝试创建一个 2d 自上而下的赛车游戏。这个游戏每次玩家玩游戏都会有一张随机路线图。我想过用两种不同的方式来做这件事:瓷砖地图,或者只是通过放置不同的预制件(直路、转弯等)来生成道路。我决定走预制路线。
我认为它应该起作用的方式是让预制方形“瓷砖”在边缘设置自己的对撞机,这样我就可以判断玩家是否偏离轨道,在这种情况下他们会爆炸。我将有一个 MapGenerator 脚本,它将通过跟踪最后放置的瓷砖(包括其位置和道路类型:左转、直行、右转等)来生成初始随机地图。当玩家越来越接近终点时,此脚本将继续随机添加到道路上,从而使其成为一条无限的道路。
我只是想知道这是否效率不高,或者我的想法是否完全错误。
这里有几张图片显示了我在 Photoshop 中制作的道路瓷砖,然后是一条直路预制件(注意其边缘的碰撞器)。
与我想要制作的游戏类似的游戏是 Sling Drift,如果您愿意,我可以提供链接。我不知道向论坛聊天添加链接的政策。
//Type of tyle,types are normal (straight road or horizontal road) and turns
public enum MapTileType
{
norMAL,N_E,N_W,S_E,S_W
}
//structure for holding the last tile location and its type.
public struct TypedTileLocation
{
public TypedTileLocation(Vector2 pos,MapTileType tyleType)
{
m_tileType = tyleType;
m_position = pos;
}
public Vector2 m_position;
public MapTileType m_tileType;
}
public class MapGenerator : MonoBehavIoUr
{
//Map Tiles
public GameObject m_roadTile;
public GameObject m_turnnorthWestTile;
//holds all the tiles made in the game
private List<GameObject> m_allTiles;
//Map Tile Widths and Height
private float m_roadTileWidth,m_roadTileHeight;
//Used for generating next tile
TypedTileLocation m_lastTilePlaced;
private void Awake()
{
//store the initial beginning tile location (0,0)
m_lastTilePlaced = new TypedTileLocation(new Vector2(0,0),MapTileType.norMAL);
//set height and width of tiles
m_roadTileWidth = m_roadTile.GetComponent<Renderer>().bounds.size.x;
m_roadTileHeight = m_roadTile.GetComponent<Renderer>().bounds.size.y;
m_allTiles = new List<GameObject>();
}
// Start is called before the first frame update
void Start()
{
SetupMap();
}
void SetupMap()
{
//starting at the beginning,just put a few tiles in straight before any turns occur
for (int i = 0; i < 6; ++i)
{
GameObject newTempTile = Instantiate(m_roadTile,new Vector2(0,m_roadTileHeight * i),Quaternion.identity);
m_lastTilePlaced.m_tileType = MapTileType.norMAL;
m_lastTilePlaced.m_position.x = newTempTile.transform.position.x;
m_lastTilePlaced.m_position.y = newTempTile.transform.position.y;
m_allTiles.Add(newTempTile);
}
//Now lets create a starter map of 100 road tiles (including turns and straigt-aways)
for (int i = 0; i < 100; ++i)
{
//first check if its time to create a turn. Maybe I'll randomly choose to either create a turn or not here
//draw either turn or straight road,if the tile was a turn decide which direction we are Now going (N,W,E,S).
//this helps us determine which turns we can take next
//repeat this process.
}
}
void GenerateMoreMap()
{
//this will generate more map onto the already existing road and then will delete some of the others
}
// Update is called once per frame
void Update()
{
}
private void OnDrawGizmos()
{
}
}
谢谢!

你试过样条曲线吗?它们可让您轻松制作赛道等弯曲路径。如果没有,这里的视频可能会有所帮助:https://www.youtube.com/watch?v=7j_BNf9s0jM。
