underwater entity that hides

[mild glade]

i need an underwater entity when scared (detects an entity nearby) will play an animation, sink to the bottom and stay still until not scared

Do you want it to play an animation or just sink to the bottom?

• minecraft:timer - to play an event after the animation plays
• minecraft:behavior.avoid_mob_type - entity avoiding the player

sink and then play anim

Here's how I would do it.

If it's a floating entity that is on the surface of the water all the time. Use "minecraft:buoyant"

What you can do is add it in a component group that spawns alongside this entity. Add two events after that decided when to remove this component group.

Something like:
"component_groups": {
"sample:is_floating": {
"minecraft:buoyant":{}
}
},

and the Events:

"events":{
"minecraft:entity_spawned":{
"add":{
"component_groups":[
"sample:is_floating"
]
},
"sample:sink_to_bottom":{
"remove":{
"component_groups":[
"sample:is_floating"
]
},
"run_command":{
"command":[
"/playanimation (whatever animation you want it to play)"
]
}
}

You can try this out I suppose. Haven't tried it myself or checked for errors in the syntax.

If you want an entity that CAN float, something that swims around. Same concept, just add the components that make it float in the component group and once you remove/replace those components it should force the entity to sink.
