2D Flame _amp; Smoke practice

[翻译] : 大家好！很长时间没有更新了，但我有了关于火焰和烟雾行为的新知识。我想在做这个之后，我需要做一些水练习动画，然后再做一些全屏宽的动画。

Hello everyone! Pretty long time without updates, but I_ve came with new knowledge about flame _ smoke behaviour. I think I gotta do some water practice animations after this, and some full_screen wide animations later.
