KX_VertexProxy(SCA_IObject)

base class — SCA_IObject

class bge.types.KX_VertexProxy

A vertex holds position, UV, color and normal information. You can only read the vertex properties of a mesh object. In upbge 0.3+, KX_MeshProxy, KX_PolyProxy, and KX_VertexProxy are only a representation of the physics shape as it was when it was converted in BL_DataConversion. Previously this kind of meshes were used both for render and physics, but since 0.3+, it is only useful in limited cases. In most cases, bpy API should be used instead.

Note: The physics simulation doesn’t currently update KX_Mesh/Poly/VertexProxy.

XYZ

The position of the vertex.

Type:: Vector((x, y, z))

UV

The texture coordinates of the vertex.

Type:: Vector((u, v))

uvs

The texture coordinates list of the vertex.

Type:: list of Vector((u, v))

normal

The normal of the vertex.

Type:: Vector((nx, ny, nz))

color

The color of the vertex.

Type:: Vector((r, g, b, a))

Black = [0.0, 0.0, 0.0, 1.0], White = [1.0, 1.0, 1.0, 1.0]

colors

The color list of the vertex.

Type:: list of Vector((r, g, b, a))

x

The x coordinate of the vertex.

Type:: float

y

The y coordinate of the vertex.

Type:: float

z

The z coordinate of the vertex.

Type:: float

u

The u texture coordinate of the vertex.

Type:: float

v

The v texture coordinate of the vertex.

Type:: float

u2

The second u texture coordinate of the vertex.

Type:: float

v2

The second v texture coordinate of the vertex.

Type:: float

r

The red component of the vertex color. 0.0 <= r <= 1.0.

Type:: float

g

The green component of the vertex color. 0.0 <= g <= 1.0.

Type:: float

b

The blue component of the vertex color. 0.0 <= b <= 1.0.

Type:: float

a

The alpha component of the vertex color. 0.0 <= a <= 1.0.

Type:: float

getXYZ()

Gets the position of this vertex.

Returns:: this vertexes position in local coordinates.
Return type:: Vector((x, y, z))

getUV()

Gets the UV (texture) coordinates of this vertex.

Returns:: this vertexes UV (texture) coordinates.
Return type:: Vector((u, v))

getUV2()

Gets the 2nd UV (texture) coordinates of this vertex.

Returns:: this vertexes UV (texture) coordinates.
Return type:: Vector((u, v))

getRGBA()

Gets the color of this vertex.

The color is represented as four bytes packed into an integer value. The color is packed as RGBA.

Since Python offers no way to get each byte without shifting, you must use the struct module to access color in an machine independent way.

Because of this, it is suggested you use the r, g, b and a attributes or the color attribute instead.

import struct;
col = struct.unpack('4B', struct.pack('I', v.getRGBA()))
# col = (r, g, b, a)
# black = (  0, 0, 0, 255)
# white = (255, 255, 255, 255)

Returns:: packed color. 4 byte integer with one byte per color channel in RGBA format.
Return type:: integer

getNormal()

Gets the normal vector of this vertex.

Returns:: normalized normal vector.
Return type:: Vector((nx, ny, nz))
