constructor

new Color(

Accessors

life

get life(): number
Gets the behaviour's life.

Returns number
Inherited from Behaviour.life
- Defined in src/behaviour/Behaviour.ts:65
set life(life: number): void
Ensures that life is infinity if an invalid value is supplied.
Parameters
- life: number
Returns void
Inherited from Behaviour.life
- Defined in src/behaviour/Behaviour.ts:58

same

get same(): boolean
Gets the _same property which determines if the alpha are the same.

Returns boolean
- Defined in src/behaviour/Color.ts:57
set same(same: boolean): void
Sets the _same property which determines if the alpha are the same.
Parameters
- same: boolean
Returns void
- Defined in src/behaviour/Color.ts:64

Methods

applyBehaviour

applyBehaviour(target: Particle | Emitter, time: number, index?: number): void
Apply behaviour to the target as a factor of time.
Parameters
- target: Particle | Emitter
- time: number
- Optionalindex: number
Returns void
Inherited from Behaviour.applyBehaviour
- Defined in src/behaviour/Behaviour.ts:93

`Abstract`destroy

destroy(): void
Destroy this behaviour.

Returns void
Inherited from Behaviour.destroy
- Defined in src/behaviour/Behaviour.ts:140

energize

energize(particle: Particle, time: number, index?: number): void
Compares the age of the behaviour vs integration time and determines if the behaviour should be set to dead or not.
Parameters
- particle: Particle

- Optionalindex: number
Returns void
Inherited from Behaviour.energize
- Defined in src/behaviour/Behaviour.ts:116

`Abstract`fromJSON

fromJSON(json: Record<string, unknown>): void
Returns a new instance of the behaviour from the JSON object passed.
Parameters
- json: Record<string, unknown>
Returns void
Inherited from Behaviour.fromJSON
- Defined in src/behaviour/Behaviour.ts:147

`Abstract`initialize

initialize(particle: Particle): void
Set the behaviour's initial properties on the particle.
Parameters
- particle: Particle
Returns void
Overrides Behaviour.initialize
- Defined in src/behaviour/Color.ts:81

`Abstract`mutate

mutate(particle: Particle, time: number, index?: number): void
Change the target's properties according to specific behaviour logic.
Parameters

- time: number
- Optionalindex: number
Returns void
Overrides Behaviour.mutate
- Defined in src/behaviour/Color.ts:90

normalizeForce

normalizeForce(force: Vector3D): Vector3D
Normalize a force by 1:100.
Parameters

normalizeValue

normalizeValue(value: number): number
Normalize a value by 1:100.
Parameters
- value: number
Returns number
Inherited from Behaviour.normalizeValue
- Defined in src/behaviour/Behaviour.ts:79

reset

reset(
    colorA?: string,
    colorB?: string,
    life?: number,
    easing?: EasingFunction,
): void
Reset this behaviour's parameters.
Parameters
