I want make a "Jail"

yeah so basically mcreator does not like the idea of recipient of attack triggers, so no way to do that as of now I think

without javascript ofc

what are the results when you try it? i may be able to help

I mean you could do a "jail dimension" where at 0 0 0 there is a jail structure spawned

If I'm understanding you correctly, you're wanting an item that makes an entity stuck, or "jails" them for a desired period of time. One way to do this would be to set a trigger for when an entity is hit with the item that gives it the maximum value of slowness (255) which will effectively freeze the entity in place. You can then specify the time in ticks that the effect will last and whether or not you want it to show particles. Obviously, this method has the side effect of ridiculously zooming in the player's FOV due to the high value of the effect, but it's what I can think of right now. I hope this helps. Have a great day! :D

Entity hurt

• If source entity main hand item is (your item)

1. Set logic NBT "Jailed" (custom tag) to True
2. Set number NBT "JailTime" (custom tag) to 30
3. Set number NBT "jailedX" (custom tag) to Entity x
4. Set number NBT "jailedY" (custom tag) to Entity y
5. Set number NBT z "jailedZ (custom tag) to Entity z

Player tick update

• If Jailed

1. If not Entity x is jailedX AND [Entity y is jailedY AND Entity z is jailedZ]
2. - Move to jailedX, jailedY, jailedZ
3. while JailTime > 0
4. - wait 20 ticks
5. - - Set JailTime to JailTime - 1
6. If JailTime is 0
7. - Set Jailed to False

So let me explain

When an Entity is hit with your jailing item, their custom tags are set and on next player tick the If Jailed condition will be activated and will not only teleport the player to their jailed spot (in my case ON the spot where they were hit) but it also has a 30 second timer until they are unjailed

The - are to indicate they are inside the function above (mobile cant tab sadly)

20 tick = 1 second

All this should work given you are in 2020.4 and up
