Checking if a foundation is twig and changing it to stone

How would this be performed with the OnEntityBuilt hook?

 

All your questions already answered.
Create a new thread instead of finding exists - a bad idea.

 

Couldnt find any but would buildingblock.grade work?

 

Try with

Code:

entity.BuildCost()

.

 

So set the build cost to how much it takes to build? What if there are multiple building blocks like roof, wall, and floor?

 

Look BGrade/BGrade.cs at master · umods/BGrade · GitHub , OnEntityBuilt method.
Code is not mine, it's from BGrade plugin, so sorry
