### `ltool.plant_tree(tree_id, pos)` ### `ltool.plant_tree(tree_id, pos, seed)`
Plants a tree as the specified position. Plants a tree as the specified position.
#### Parameters #### Parameters
* `tree_id`: ID of tree to be planted * `tree_id`: ID of tree to be planted
* `pos`: Position of tree, in the format `{x=?, y=?, z=?}` * `pos`: Position of tree, in the format `{x=?, y=?, z=?}`
* `seed`: Optional randomness seed, equal seed creates equal trees
#### Return value #### Return value
`false` on failure, `nil` otherwise. `false` on failure, `nil` otherwise.
