BehaviorRunner

One agent running one tree.

class BehaviorRunner<Context>

import { BehaviorRunner } from '@driftengine/core';

In depth

A character per agent and one tree between them: the tree is read-only after building, and everything that differs between two villagers following the same routine is here.

Constructor

`new`

constructor(tree: BehaviorTree)

Parameter	Type	Description
`tree`	`BehaviorTree`

Properties

Name	Type	Description
`tree`readonly	`BehaviorTree`
`paused`	`boolean`	When true, `tick` does nothing and reports the last status. More Paused rather than not-called, so a debugger can hold one agent while the world runs — and so `stepOnce` has something to mean.

Accessors

Name	Type	Description
`status`get	`BehaviorStatus`

Methods

`tick`

tick(context: Context): BehaviorStatus

Advance one tick, unless paused.

Parameter	Type	Description
`context`	`Context`

`stepOnce`

stepOnce(context: Context): BehaviorStatus

Advance one tick even while paused. What a step button is wired to.

Parameter	Type	Description
`context`	`Context`

`reset`

reset(): void

Forget everything: the next tick starts the routine from the beginning.

`activePath`

activePath(out: Uint32Array): number

The chain of nodes the last tick was inside, root first, filled into out.

Parameter	Type	Description
`out`	`Uint32Array`

This is the inspection the report asked for, and it costs nothing to keep: the chain is recorded as the tick descends, so asking for it later is a copy rather than a second walk. nameOf turns the indices into the names the tree was written with.

`nameOf`

nameOf(node: number): string

Parameter	Type	Description
`node`	`number`
