Solid Entities
recipe
intermediate
Solid entities are entities that the player can bump into, step on, or otherwise physically interact with without passing through. Entities like this have many uses, such as emulating blocks.
This page will discuss some of the ways that solid entities can be created.
Not all techniques are ideal for all scenarios. Experiment, and figure out what works best for you.
Runtime Identifiers
Runtime identifiers can be used to achieve solid entities, but currently only 2, each with a specific shape, and their own side effects. Neither collision shapes are possible to change or scale.
Boat
{
"format_version": "1.16.0",
"minecraft:entity": {
"description": {
"identifier": "wiki:solid_entity",
"runtime_identifier": "minecraft:boat"
. . .
}
}

- Boat-shaped solid collision
- Certain other boat-like effects
Shulker
{
"format_version": "1.16.0",
"minecraft:entity": {
"description": {
"identifier": "wiki:solid_entity",
"runtime_identifier": "minecraft:shulker"

- 1x1 block sized solid collision.
- Sticks to block grid.
- Teleports randomly when supporting block removed.
minecraft:is_stackable
Add minecraft:is_stackable to your entity you want to be treated as being solid. Note: This requires editing player.json if you wish the entity to be solid for the player.
"minecraft:is_stackable": {}
You will also need to add minecraft:push_through and set its value parameter to 1.
"minecraft:push_through": 1
(they should both go in components)
Faking it with blocks
In some scenarios, it's probably better to /setblock or /fill to place barrier blocks, either statically or dynamically. There needs to be both a way of placing the barriers, and removing them.
/fill ~ ~ ~ ~ ~1 ~ barrier 0 replace air Places barriers in a 1x1x2 area.
/fill ~1 ~1 ~1 ~-1 ~-1 ~-1 air 0 replace barrier Removes barriers within a 3x3x3 area.
These commands will have to be triggering at a constant rate, for consistency. They can either be triggered through entity components, or animation controllers.
