Example 1 with BlockHitResult

use of net.minecraft.world.phys.BlockHitResult in project MinecraftForge by MinecraftForge.

the class FluidUtil method tryPlaceFluid.

/**
 * Tries to place a fluid resource into the world as a block and drains the fluidSource.
 * Makes a fluid emptying or vaporization sound when successful.
 * Honors the amount of fluid contained by the used container.
 * Checks if water-like fluids should vaporize like in the nether.
 *
 * Modeled after {@link BucketItem#emptyContents(Player, Level, BlockPos, BlockHitResult)}
 *
 * @param player      Player who places the fluid. May be null for blocks like dispensers.
 * @param world       Level to place the fluid in
 * @param hand
 * @param pos         The position in the world to place the fluid block
 * @param fluidSource The fluid source holding the fluidStack to place
 * @param resource    The fluidStack to place.
 * @return true if the placement was successful, false otherwise
