BehaviorNodeDefinition

Remarks

The tree as a person drew it: a root with children, each carrying its own decorators and services as lists. Children is ordered, and that order is the whole priority ordering of the compiled tree.

⚠ Child order is stored, not derived from a position on a canvas. Unreal derives it from the horizontal position of the child nodes, which makes three ordinary gestures dangerous: auto-layout re-derives positions, so laying the graph out silently reorders the tree; dragging a node six pixels left to line it up with its sibling changes which branch wins; and a merge that resolves two positions produces a tree neither author wrote, with a diff showing only coordinates. All three are silent and all three change what the agent does — doc 37 § D5.
