Make a block delete water 1.15.2

[LostALifeGaming]

Hi im very new to forge mdk and have never done java before so im self teaching.

 

Im making a mod that provides a drain and when placed will over time delete water source blocks around it. I want it to delete the water from the top down. So if you have a room full of water it will read the top layer that has water in it and count how many water source block are on that y plane. It will the take the amount of water blocks and times it by something like 3 so that for each block of water in the room, 3 seconds is added to the amount of time required to pass before the water in that y layer is removed.

 

I am unsure how to make the block replace water with air or what function to use. Right now i just want to focus on getting the block to delete water. 

 

Sorry if my explanation is unclear.

Thanks for the help.

Do java first, then come back and try to do modding. Learning both at the same time is a terrible way to start programming.

Highly ambitious and also problematic. Unloaded areas will be affected and it will be editing a wide range of blocks like a multipart. Since it's also not in a standard shape, it becomes even more of an issue. There are a few way I can think of though, but that's regardless of any lag.

World#setBlockState or World#destroyBlock should do nicely.

I understand what you mean but whenever i have come across a term i dont understand (I know basic C# so im not completely new to programming) i end up searching it up and most of the time that works for me and i dont mind the challenge of learning java while making the mod. If anything it means when i learn something new i can remember it by what i used it for.

Ok thanks for telling me, what do you suggest would be a resonable way to do it?

Ok thanks but where would this need to be. Would it sit in a class for when the block is placed or does it passively run in all instances of the block.

There's not really a reasonable way to do it. The bigger the water size, the more checks needed and the greater amount of lag on the system. There's no real optimization in something like this other than caching block positions which are water.

Probably in a tile entity of some sort since you require some kind of timing feature.

Less of a challenge and more of falling into bad habits looking at very problematic code. Hence why we suggest not starting it that way as it only detriments your learning.

Ok i will have a look into java begginer tutorials.

Thanks i'll have a look into tile entity development

I ended up finding a video on making a tile entity but when i make a new tile entity class it wont let me make the constructor.

That has me worried.

Where? The type takes a supplier while the create method takes a new instance.

I have decided to step back from making a tile entity and will start with a simpler mod just to learn new things and methods. Thanks for trying to help.
