The textures are not rendered (Tutorial 5)

[norman784]

Theres an issue and the textures are not rendered, so my best bet is that something is wrong with the pixels byte array passed to the glTexImage2D.

For the record the issue was that a value was not passed correctly to the glVertexAttribPointer, and solved with this:

val colorStartPosition: Long = 6 * FloatVar.size
glVertexAttribPointer(
  1, 
  3, 
  GL_FLOAT, 
  GL_FALSE.narrow(), 
  (8 * FloatVar.size).toInt(),
  colorStartPosition.toCPointer<COpaque>() // CORRECT
)

previously I was using cValuesOf like this:

glVertexAttribPointer(
  1, 
  3, 
  GL_FLOAT, 
  GL_FALSE.narrow(), 
  (8 * FloatVar.size).toInt(),
  cValuesOf(6 * FloatVar.size) // WRONG
)
