Hi try to generate procetual mesh and start with a simple cube implementation.
But i run into basic problems like coloring and texturing. It not works
here my simple code
extends MeshInstance
#export(SpatialMaterial) var material = null
func _ready():
var size = 5
var vertexList = [
Vector3(size, size, size),
Vector3(-size, size, size),
Vector3(size, size, -size),
Vector3(-size, size, -size),
Vector3(size, -size, size),
Vector3(-size, -size, size),
Vector3(-size, -size, -size),
Vector3(size, -size, -size)]
var strip = [ 3, 2, 6, 7, 4, 2, 0, 3, 1, 6, 5, 4, 1, 0 ]
var surfaceTool = SurfaceTool.new()
surfaceTool.begin(Mesh.PRIMITIVE_TRIANGLE_STRIP)
for surface in range(0, strip.size()):
var vertex = vertexList[strip[surface]]
surfaceTool.add_vertex( vertex)
surfaceTool.add_color(Color(0,0,1,1))
#surfaceTool.add_uv( Vector2(1/vertex.x, 1/vertex.y))
#surfaceTool.add_uv2( Vector2(1/vertex.x, 1/vertex.y))
var material = SpatialMaterial.new()
#material.albedo_color = Color(0,0,1,1)
surfaceTool.generate_normals()
surfaceTool.set_material(material)
surfaceTool.index()
var mesh = Mesh.new()
surfaceTool.commit(mesh)
set_mesh(mesh)
the loop to set the color not works, only when i set globaly the material color it works.
same for textures, what i doing wrong?
I guess is a problem of normals, after reading offical docu
void generate_normals( bool flip=false )
Generates normals from Vertices so you do not have to do it manually.
Setting "flip" true inverts resulting normals.
Requires primitive type to be set to PRIMITIVE_TRIANGLES.
Is realy only type PRIMITIVE_TRIANGLES supported?
Thanks for help
