AnimationTreePlayer

Inherits: Node < Object

Deprecated. Animation player that uses a node graph for blending animations. Superseded by AnimationTree.

Description

Deprecated. A node graph tool for blending multiple animations bound to an AnimationPlayer. Especially useful for animating characters or other skeleton-based rigs. It can combine several animations to form a desired pose.

It takes Animations from an AnimationPlayer node and mixes them depending on the graph.

See AnimationTree for a more full-featured replacement of this node.

• NODE_ANIMATION = 1 —- Animation node.
• NODE_ONESHOT = 2 —- OneShot node.
• NODE_MIX = 3 —- Mix node.
• NODE_BLEND2 = 4 —- Blend2 node.

• NODE_TIMESEEK = 8 —- TimeSeek node.
• NODE_TRANSITION = 9 —- Transition node.

enum AnimationProcessMode:

• ANIMATION_PROCESS_PHYSICS = 0 —- Process animation during the physics process. This is especially useful when animating physics bodies.
• ANIMATION_PROCESS_IDLE = 1 —- Process animation during the idle process.

Property Descriptions

• bool active

If true, the AnimationTreePlayer is able to play animations.

• NodePath base_path

The node from which to relatively access other nodes.

It accesses the bones, so it should point to the same node the AnimationPlayer would point its Root Node at.

• NodePath master_player

The path to the AnimationPlayer from which this AnimationTreePlayer binds animations to animation nodes.

Once set, Animation nodes can be added to the AnimationTreePlayer.

• AnimationProcessMode playback_process_mode

The thread in which to update animations.
