Animated Java

Overview

Animated Java generates a set of functions for each animation defined in your Blueprint. All animation functions must be executed as the root entity of a rig instance.

Function Reference

All functions below live at <blueprint_id>/animations/<animation_name>/....

Replace <blueprint_id> and <animation_name> with your values. Functions must be executed as the root entity.

play

Starts playing the animation from frame 0. Does not affect other currently-playing animations.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/play

play_exclusive

Pauses all other animations on this rig, then starts playing this animation from frame 0.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/attack/play_exclusive

stop

Pauses all animations and resets the rig back to its default pose.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/stop

pause

Freezes the animation at its current frame.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/pause

resume

Resumes the animation from the frame it was paused on.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/resume

next_frame

Manually advances the animation by exactly one frame, handling loop wrapping internally. Useful for step-by-step control.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/next_frame

set_frame

Seeks the animation to a specific frame without triggering keyframe effects (locator callbacks, variant keyframes, function keyframes). The pose is snapped instantly.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/set_frame {frame: 5}

apply_frame

Seeks to a specific frame and triggers all keyframe effects for that frame.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/apply_frame {frame: 5}

tween

Smoothly interpolates from the rig’s current pose into a specific frame of this animation over a given number of ticks. All currently-playing animations are paused during the tween.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/tween {duration: 10, to_frame: 0}

duration — The number of ticks the transition takes.
to_frame — The target animation frame to interpolate to.

pause_all

Pauses every animation on this rig simultaneously.

execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/pause_all

Keyframe Types

In addition to transform keyframes, animations support two special keyframe types in Blockbench’s Effects channel:

Variant Keyframe — Applies a named variant at a specific frame. Add it in the Effects timeline and select the variant to apply.
Function Keyframe — Runs an arbitrary MCfunction at a specific frame. The function is executed as and at the root entity.

Playing Multiple Animations Simultaneously

Since animations only update the bones in their modified_nodes set, you can play multiple animations at the same time — as long as they affect different bones.

# Play a walk cycle and an upper-body attack at the same time
execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/walk/play
execute as @e[tag=my_pack.my_rig.root] run function my_pack:my_rig/animations/attack/play

Configure which bones each animation controls using Excluded Nodes in Animation Properties.
