Hello! The following code is intended to render a smoothly shaded triangle, but it only clears the background to a dark blue!
Import mojo
Import opengl.gles11
Class MyApp Extends App
Field inited
Field vertices : Int[] = [-1,1,0,1,-1,0,1,1,0]
Field colors : Int[] = [255,0,0,255,0,255,0,255,0,0,255,255]
Field verticesdata := New DataBuffer(36)
Field colorsdata := New DataBuffer(48)
Method OnCreate()

End
Method initGLES()
