[languid sequoia]

H ow

Or a type a command

Basically when a command is triggered

[ashen yew]

/playanimation
Or look into entity properties and check them client-side in an animation controller

what kirby said. make your animation in blockbench, (or if you have one already open it in there or another app/tool)

put it in the animations folder (if its controllers, animation_controllers)

you can use the play animation command, but you can also build a mcfunction file to run commands to simplify it into one /function animation_1 (for example)
