Example 25 with BlockState

use of net.minecraft.world.level.block.state.BlockState in project Denizen-For-Bukkit by DenizenScript.

the class EntityHelperImpl method setFallingBlockType.

@Override
public void setFallingBlockType(FallingBlock entity, BlockData block) {
    BlockState state = ((CraftBlockData) block).getState();
    FallingBlockEntity nmsEntity = ((CraftFallingBlock) entity).getHandle();
    try {
        FALLINGBLOCK_TYPE_SETTER.invoke(nmsEntity, state);
    } catch (Throwable ex) {
        Debug.echoError(ex);
