I read this tutorial：https://docs.godotengine.org/en/stable/tutorials/content/procedural_geometry/arraymesh.html
and create gd script like the tutorial. but i can not see a sphere in camera.
Did i do something wrong.
this is my code
extends MeshInstance
var rings = 50
var radial_segments = 50
var height = 1
var radius = 1
func _ready():
var arr = []
arr.resize(Mesh.ARRAY_MAX)
var verts = PoolVector3Array()
var uvs = PoolVector2Array()
var normals = PoolVector3Array()
var indices = PoolIntArray()
var thisrow = 0
var prevrow = 0
var point = 0
# Loop over rings.
for i in range(rings + 1):
var v = float(i) / rings
var w = sin(PI * v)
var y = cos(PI * v)
# Loop over segments in ring.
for j in range(radial_segments):
var u = float(j) / radial_segments
var x = sin(u * PI * 2.0)
var z = cos(u * PI * 2.0)
var vert = Vector3(x * radius * w, y, z * radius * w)
verts.append(vert)
normals.append(vert.normalized())
uvs.append(Vector2(u, v))
point += 1
# Create triangles in ring using indices.
if i > 0 and j > 0:
indices.append(prevrow + j - 1)
indices.append(prevrow + j)
indices.append(thisrow + j - 1)
indices.append(prevrow + j)
indices.append(thisrow + j)
indices.append(thisrow + j - 1)
if i > 0:
indices.append(prevrow + radial_segments - 1)
indices.append(prevrow)
indices.append(thisrow + radial_segments - 1)
indices.append(prevrow)
indices.append(prevrow + radial_segments)
indices.append(thisrow + radial_segments - 1)
prevrow = thisrow
thisrow = point
arr[Mesh.ARRAY_VERTEX] = verts
arr[Mesh.ARRAY_TEX_UV] = uvs
arr[Mesh.ARRAY_NORMAL] = normals
arr[Mesh.ARRAY_INDEX] = indices
mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, arr)
i need your help please,thanks a lot.
BR.
