b2dMeshFaceR - BambooBasic

b2dMeshFaceR

Category: 2D Overlay

Syntax:

b2dMeshFaceR:Int(handle:Int, face:Int)

Parameters

handle : Int — mesh handle from b2dLoadMesh
face : Int — face index, 0 to b2dMeshFaceCount - 1

Returns

Red, 0..255

Summary

The red part of a face's base colour, from the material it was given in the modelling program. b2dMeshFaceG and b2dMeshFaceB give green and blue.

Use these for a model with no texture (b2dMeshTexture returns 0): set the colour, optionally darkened by how the face points towards a light, and draw the face with b2dDrawQuadDepth.

Returns 255 (white) for a mesh saved without material colours, and for an unknown handle or face, so an old untextured model still draws as something.
