Creating a high performance tiled ground mesh with SPS & spritesheet

[aWeirdo]

Hi all,

Some weeks ago i needed to make a large tiled ground, 
i tried the build-in createTiledGround, but at "just" 50 x 50 tiles (2500), it starts to struggle a bit, even on a rather high-end PC.

So using the SPS and a spritesheet, i created my own;
It takes a second to load,
but at 500 x 500 tiles, (250.000) it runs smoothly and with 59 / 60 fps on the same PC.

 

tile indexing example, 5x5 (25) tiles;

    Cols_> 0   1   2   3   4 
Rows_V
          4    20 21 22 23 24
          3   15 16 17 18 19
          2    10 11 12 13 14
          1    05 06 07 08 09
          0    00 01 02 03 04

other important stuff should be commented in the PG.
