I tried making a copy of a vertex array using the slice notation...
textLayer = extraTextBuffer[:]
... and this is what happens:
# File "graphics.pyx", line 1587, in sfml.graphics.VertexArray.__getitem__ (src/sfml\graphics.cpp:26182)
# TypeError: an integer is required
I'm confused as to why this happens.
(EDIT: Probably because VertexArrays are not python Lists! I realized later.)I want to copy the array by value, and I can copy it by iterating through it, but that's quite a slow process (because the array is BIG). My goal was to check if using slice notation was significantly faster or not.
Basically my idea here is to have a vertex array with default values (colors and tex_coords), and simply use it to "clear" the one I'm using every frame. I'm doing this to test how it might affect performance. Iterating through a vertexarray and reseting all the vertices is also a rather slow process. Perhaps even slower than copying vertices from another array.
Simply copying like
array1 = array2
seems to copy them by reference, as it would a python list.
