Pyglet+Shader+ECS

The pyglet is realy comfortable as graphical engine but it has a problem with geometry updating. By default we cannot work with vertices, textures, and colors in shaders. A little patching and everything fine. Also there is an experiment to work with Entity Component System

• pip3 install pyprof2calltree
• kcachegrind

most important changes in vertexattribute.py

glEnableClientState -> glEnableVertexAttribArray(<SHADER_LAYOUT__LOCATION_INDEX>) glTexCoordPointer -> glVertexAttribPointer()

Now layot location indexes are:

• 0 - vertices
• 1 - texture uvw
• 2 - vertex colors

Instanced draw
