Godot -我如何让我的块在玩家周围生成一个3 × 3的网格

Question

我如何在3 × 3网格中生成块，以便在场景中始终有9个网格实例?目前，每当玩家移动到一个新区域/块时，我只生成一个块。

为了让你们更容易，我把它放在github仓库里，这样你们就可以下载和尝试了!https://github.com/Dragon20C/GODOT--Flat-Terrain-Generation

相关代码:

var chunk_x = floor(player.translation.x / chunk.size)
var chunk_z = floor(player.translation.z / chunk.size)
var new_chunk_pos = Vector2(chunk_x, chunk_z)

if new_chunk_pos != chunk_pos:
if !new_chunk_pos in previous_chunks:
chunk_pos = new_chunk_pos
var instance = chunk_scene.instance()
add_child(instance)
instance.chunk_position_set(Vector3(chunk_pos.x * chunk.size,0,chunk_pos.y * chunk.size))
previous_chunks.append(chunk_pos)

Answer 1

将此代码提取为一个新函数:

if !new_chunk_pos in previous_chunks:
chunk_pos = new_chunk_pos
var instance = chunk_scene.instance()
add_child(instance)
instance.chunk_position_set(Vector3(chunk_pos.x * chunk.size,0,chunk_pos.y * chunk.size))
previous_chunks.append(chunk_pos)

则称其为传递new_chunk_pos及其周围块的位置。即x在new_chunk_pos.x - 1到new_chunk_pos.x + 1范围内，y在new_chunk_pos.y - 1到new_chunk_pos.y + 1范围内的位置。
