Floodgate VS Bridge What the different?

[NepuNepuNEP]

I saw tutorial in youtube some use floodgate and some use bridge. What the different between this two?

Assuming that this is in the context of fluid control, bridges can effectively function as the negative operator of a flood gate. Specifically, a floodgate will be open when it is receiving a signal, while a bridge will be closed. So if you have a pressure plate to generate that signal, you can have floodgates open when fluid exceeds the limit, while bridges would close when the fluid exceeds the limit. They effectively behave the same, depending on where the pressure plate is in the fluid circuit.

The bridge does have the advantage of being impossible to break. While the floodgate does not. Unless it is an artifact, a building destroyer type creatures can break through the floodgate.

There is talk that the bridge imperviousness may be changed in some future update. But until that happens, bridges, like walls, are a "perfect" defense.

Oh, also....

A floodgate can become stuck on something that water pressure may bring into its area. A bridge would either throw or atom-smash anything in its way.

Floodgates have the advantages of being quicker to make and more compact; instead of having a mason make the bridge where you want it, you can have the floodgate premade and plop them as needed. The main disadvantages of floodgates is that they can get clogged and forced open or broken by building destroying monsters, which bridges are immune to.

You can use floodgates for more than just fluid management, too; they just become an impassable to most creature block when enabled. So if you want to raise some walls that have a little less crushing potential than bridges, you can use floodgates.
