KX_VertexProxy(SCA_IObject)

base class — SCA_IObject

class bge.types.KX_VertexProxy(SCA_IObject)

A vertex holds position, UV, color and normal information.

Note: The physics simulation is NOT currently updated - physics will not respond to changes in the vertex position.

XYZ

The position of the vertex.

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

The texture coordinates of the vertex.

Type: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]

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))
setXYZ(pos)

Sets the position of this vertex.

Type:Vector((x, y, z))
Parameters:pos – the new position for this vertex in local coordinates.
getUV()

Gets the UV (texture) coordinates of this vertex.

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

Sets the UV (texture) coordinates of this vertex.

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))
setUV2(uv, unit)

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

Type:

Vector((u, v))
Parameters:
  • unit – optional argument, FLAT==1, SECOND_UV==2, defaults to SECOND_UV
  • unit – integer
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
setRGBA(col)

Sets the color of this vertex.

See getRGBA() for the format of col, and its relevant problems. Use the r, g, b and a attributes or the color attribute instead.

setRGBA() also accepts a four component list as argument col. The list represents the color as [r, g, b, a] with black = [0.0, 0.0, 0.0, 1.0] and white = [1.0, 1.0, 1.0, 1.0]

v.setRGBA(0xff0000ff) # Red
v.setRGBA(0xff00ff00) # Green on little endian, transparent purple on big endian
v.setRGBA([1.0, 0.0, 0.0, 1.0]) # Red
v.setRGBA([0.0, 1.0, 0.0, 1.0]) # Green on all platforms.
Parameters:col (integer or list [r, g, b, a]) – the new color of this vertex in packed RGBA format.
getNormal()

Gets the normal vector of this vertex.

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

Sets the normal vector of this vertex.

Type:sequence of floats [r, g, b]
Parameters:normal – the new normal of this vertex.
