Originally, the teardrop was at 1 opacity, and the code would repeatedly remove -0.2 until it was not GREATER than 0. To modify the code, simply swap everything. First, make the initial opacity 0. Then go in the code and make sure that, while the opacity is LESS THAN 1, it will gain 0.2 opacity until it does.

Yes but why did the end disappear

I'm supposing this is what you meant, no?
