I want to use Arraymesh to generate geometry for procedural level generation. I want to be able to generate both quads and triangles from simple vertex data. The script that i had written seems to work when dealing with the quadGeneration or triangleGeneration functions alone, but it doesn’t work properly or at all when both are active in the script. What could cause this to happen and how can i fix this? Here’s the code:
extends MeshInstance
export var quadMeshArray = [
Vector3(0, 0, 0),
Vector3(1, 0, 0),
Vector3(1, 0, 1),
Vector3(0, 0, 1),
Vector3(1, 0, 0),
Vector3(2, 0, 0),
Vector3(2, 0, 1),
Vector3(1, 0, 1),
Vector3(-2, 0, 0),
Vector3(-1, 0, 0),
Vector3(-1, 0, 1),
Vector3(-2, 0, 1),
Vector3(-2, 0, 1),
Vector3(-1, 0, 1),
Vector3(-1, 0, 2),
Vector3(-2, 0, 2),
]
export var triangleMeshArray = [
Vector3(3, 0, 3),
Vector3(2, 0, 3),
Vector3(2, 0, 3),
]
var st = SurfaceTool.new()
func _ready():
st.begin(Mesh.PRIMITIVE_TRIANGLES)
triangleGeneration()
quadGeneration()
st.generate_normals()
mesh = st.commit()
func quadGeneration():
var vertexCount = 0
var indexCount = 0
for num in quadMeshArray.size()/4:
for i in 4:
st.add_vertex(quadMeshArray[vertexCount])
vertexCount += 1
st.add_index(indexCount)
st.add_index(indexCount + 1)
st.add_index(indexCount + 2)
st.add_index(indexCount + 3)
st.add_index(indexCount)
st.add_index(indexCount + 2)
indexCount += 4
func triangleGeneration():
var vertexCount = 0
var indexCount = 0
for num in triangleMeshArray.size()/3:
for i in 3:
st.add_vertex(triangleMeshArray[vertexCount])
vertexCount += 1
st.add_index(indexCount)
st.add_index(indexCount + 1)
st.add_index(indexCount + 2)
indexCount += 3
