Thank you :)

Hi bro! It took me a long time to find this project. There are too few examples of using c# and unity to do 2d liquid, especially the liquid similar to the effect of Terraria.
This project looks great, but there are also imperfections.
Bug:
----When there is less liquid and the container is longer, the liquid cannot completely cover the surface of the container.
Need to improve:
----The liquid flows too slowly to both sides of the container, it takes a long time to reach a stable state, which is unacceptable in the game, and the effect of the flow is not smooth, and it cannot achieve the liquid effect of Terraria.
----Objects or characters should also be visible in the liquid, so I tried to change the transparency of the liquid, but the effect looks too bad.
----Many liquid parameter settings can be written on the unity editing interface. For specific examples, please refer to ‘https://assetstore.unity.com/packages/tools/particles-effects/water-2d-136297’.
I have consulted the sellers of liquids like Terraria. They are too greedy. A mature liquid plug-in in Unity store is only 20 and 30 dollars, and they even ask for a price >=142.8$ to do the project. If you can make a finished product and sell it in Unity store, if the price is right, I am willing to buy your plug-in, knowledge and labor are worthy of respect!
