::: tip FORMAT & MIN ENGINE VERSION `1.20.30`
This tutorial assumes an advanced understanding of blocks.
Check out the [blocks guide](/wiki/blocks/blocks-intro) before starting.
:::
::: warning EXPERIMENTAL
Requires `Holiday Creator Features` for use of block tag Molang queries and to trigger block events.
:::
Creating your own tree with decaying leaves is complex, but possible! Follow this tutorial and you'll have your own in no time.
- Features:
- Decaying leaves
- Tree Feature compatable
- If leaves were broken using shears, they will drop the block
- Leaves don't decay if placed by player
- Logs are strippable and rotatable
- Stripping logs is compatible with tools from other add-ons (if they have the `minecraft:is_axe` tag)
- Saplings can be bonemealed and grow the tree (with structures)
- Issues:
- If you make a structure with these blocks, it will crash the game when generated using features.
## Decaying Leaves
You will notice straight away that our custom leaves have a long list to search for a vanilla log/custom log by its block tag, although the code example uses the custom logs for this tutorial. The value is 4 and this method is used to search for the nearest log in a circular radius.
Our custom leaves disables ticking when placed by the player which doesn't make the leaves decay and this removes the requirements for another duplicate leave block.

## Custom Sapling
For the sapling we will need structures of our tree to make the sapling semi-realistic as features cannot currently be placed with commands on Minecraft Bedrock.
BP/blocks/custom_sapling.json
```json
{
"format_version": "1.20.30",
"minecraft:block": {
"description": {
"identifier": "wiki:custom_sapling",
"states": {
// Sapling's growth stage

}
]
},
// Trigger growth on each random tick

}
},
// Trigger growth when bone meal is used

"wiki:growth_stage": "q.block_state('wiki:growth_stage') + 1"
}
},
{
"condition": "q.block_state('wiki:growth_stage') == 2",
"run_command": {
"command": "structure load custom_tree ~-2~~-2"
}
}
]

```
## Sapling Placer
BP/items/custom_sapling_placer.json
```json
{
"format_version": "1.20.30",
"minecraft:item": {
"description": {
"identifier": "wiki:custom_sapling_placer",
"menu_category": {
"category": "nature",
"group": "itemGroup.name.sapling"
}
},
"components": {
"minecraft:max_stack_size": 64,
"minecraft:block_placer": {
"block": "wiki:custom_sapling"
},
"minecraft:icon": {
"texture": "custom_sapling_placer"
}
}
}
}
```
## Loot Tables
This loot will spawn leaves block (when you break it using shears)
BP/loot_tables/blocks/custom_leaves_shears.json
```json
{
"pools": [
{
"rolls": 1,
"entries": [
{
"type": "item",
"name": "wiki:custom_leaves"
}
]
}
]
}
```
Leaves default loot
BP/loot_tables/blocks/custom_leaves.json
```json
{
"pools": [
{
"rolls": 1,
"entries": [
{
"type": "item",
"name": "minecraft:apple",
"weight": 1
},
{
"type": "item",
"name": "wiki:custom_sapling_placer",
"weight": 5
},
{
// Nothing will drop
"type": "empty",
"weight": 10
}
]
}
]
}
```
This will spawn `wiki:custom_sapling`
BP/loot_tables/blocks/custom_sapling.json
```json
{
"pools": [
{
"rolls": 1,
"entries": [
{
"type": "item",
"name": "wiki:custom_sapling_placer"
}
]
}
]
}
```
## Exporting Structures
Build a tree for your sapling to grow into!
## Tree Features

Tree Features are a really great way to get actual custom trees. You need some understanding on how they work but for this tutorial you can uses these templates.

## Resource Pack (optional guide)
Now it is time to make a resource pack!
Make translations for blocks:
RP/texts/en_US.lang
```

tile.wiki:custom_stripped_log.name=Custom Stripped Log
tile.wiki:custom_sapling.name=Custom Sapling
item.wiki:custom_sapling_placer=Custom Sapling
```
Make terrain_texture.json and textures.
RP/textures/terrain_texture.json
```json
{
