I’m using Godot 4.2.1
So I’ve been following this slightly outdated tutorial. I’d use a more up to date version but there doesn’t seem to be any. And admittedly I’m not smart enough to just figure something like this out by myself.
I didn’t have any major issue up until it used add_triangle_fan(), which upon looking it up seems to have been removed outright. I tried figuring out how to come up with a workaround, but the farthest I got by myself was generating a square with ArrayMesh.
Update: I’ve since managed to at the very least get a cube rendering. However I’m still clueless as to how I can generate multiple to fill a chunk. And I’m especially stumped on how to not render faces that would otherwise be hidden.
My code so far, if this is any help.
var mesh_data = []
var face = []
mesh_data.resize(ArrayMesh.ARRAY_MAX)
mesh_data[ArrayMesh.ARRAY_VERTEX] = PackedVector3Array([
Vector3(0, 0, 0), #0
Vector3(1, 0, 0), #1
Vector3(0, 1, 0), #2
Vector3(1, 1, 0), #3
Vector3(0, 0, 1), #4
Vector3(1, 0, 1), #5
Vector3(0, 1, 1), #6
Vector3(1, 1, 1) #7
])
mesh_data[ArrayMesh.ARRAY_INDEX] = PackedInt32Array([
#Top
2, 3, 7,
2, 7, 6,
#Bottom
0, 4, 5,
0, 5, 1,
#Left
6, 4, 0,
6, 0, 2,
#Right
3, 1, 5,
3, 5, 7,
#Front
7, 5, 4,
7, 4, 6,
#Back
2, 0, 1,
2, 1, 3
])
mesh = ArrayMesh.new()
mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, mesh_data)
