How do I select all but two types of entities in Minecraft with the type selector?

I've asked this question towards a developer for Minecraft and I thought I'd ask here too since they might not see the question.

How do I select all but two types of entities in Minecraft?

For example, something like: /say @e[type=![Player,Item],r=50] (to clarify I also tried type=Item,Player, type=Item,type=Player etc)

Should select any entity that does not match players or items, so things like Creepers, Ghasts, XPOrbs, PrimedTNT and so on within a radius of 50 blocks and print them to the chat.

Instead it ignores one of the flags, and works with the other instead.

Solution 1:

First, create a dummy scoreboard objective:

/scoreboard objectives add selectMe dummy

Then, on a fast redstone clock, give all entities a selectMe score of 1:

/scoreboard players set @e selectMe 1

Give all players and items a selectMe score of 0 with these two command blocks:

/scoreboard players set @e[type=Player] selectMe 0

/scoreboard players set @e[type=Item] selectMe 0

Now, you can select them by targeting all entities within a 50 block radius that have a selectMe score of 1:

/say @e[score_selectMe_min=1,r=50]

Hope this helped! :)

Solution 2:

As of Minecraft 1.9, scoreboard tags are a better fit for this than setting up an objective and assigning a score.

It's as easy as setting up repeat command blocks (or a repeat/chain line) and putting:

/scoreboard players tag @e[type=Player] add playerOrItem
/scoreboard players tag @e[type=Item] add playerOrItem

You can then use @e[tag=playerOrItem] and @e[tag=!playerOrItem] to select every entity that is and is not a player or item, respectively.

The benefits of using tags over scoreboard objectives are:

1. No need to set up an objective.
2. They are initialized as empty by default. I.e. @a[tag=!banana] works on every player by default, unlike @a[score_banana=0]. The means you only need to affect the targets you actually want to affect.
3. Tags are also stored in an entities NBT data, in the Tags tag.

Solution 3:

As of Minecraft 1.13 (Java Edition) you can now use multiple selectors to target entities.

From the Minecraft Wiki:

tag=foo,tag=bar,tag=!baz matches someone with foo, bar and not baz.

type=!cow,type=!chicken matches something that isn't a cow and isn't a chicken.

type=cow,type=chicken isn't allowed, because something cannot both be a cow and chicken.

For versions prior to 1.13

You can use either idtownie or this from user113642 the latter being untested.
