Methods
publicblink
Parameters
timeVisible: number
The amount of time to stay visible per blink in milliseconds
timeNotVisible: number
The amount of time to stay not visible per blink in milliseconds
numBlinks: number = 1
The number of times to blink
Returns ActionContext
publiccallMethod
This method allows you to call an arbitrary method as the next action in the action queue. This is useful if you want to execute code in after a specific action, i.e An actor arrives at a destination after traversing a path
Parameters
method: () => any
Returns ActionContext
publicclearActions
Clears all queued actions from the Actor
Returns void
publicdelay
This method will delay the next action from executing for a certain amount of time (in milliseconds). This method is part of the actor 'Action' fluent API allowing action chaining.
Parameters
duration: number
The amount of time to delay the next action in the queue from executing in milliseconds
Returns ActionContext
publicdie
This method will add an action to the queue that will remove the actor from the scene once it has completed its previous Any actions on the action queue after this action will not be executed.
Returns ActionContext
publiceaseBy
This method will move an actor by a specified vector offset relative to the current position given a duration and a EasingFunction. This method is part of the actor 'Action' fluent API allowing action chaining.
Parameters
offset: Vector
Vector offset relative to the current position
duration: number
The duration in milliseconds
optionaleasingFcn: EasingFunction<number>
Use EasingFunction or a custom function to use to calculate position, Default is EasingFunctions.Linear
Returns ActionContext
publiceaseTo
This method will move an actor to the specified
x
andy
position over the specified duration using a given EasingFunctions and return back the actor. This method is part of the actor 'Action' fluent API allowing action chaining.Parameters
pos: Vector
The x,y vector location to move the actor to
duration: number
The time it should take the actor to move to the new location in milliseconds
optionaleasingFcn: EasingFunction<number>
Use EasingFunction or a custom function to use to calculate position, Default is EasingFunctions.Linear
Returns ActionContext
publicfade
This method will cause an actor's opacity to change from its current value to the provided value by a specified time (in milliseconds). This method is part of the actor 'Action' fluent API allowing action chaining.
Parameters
opacity: number
The ending opacity
duration: number
The time it should take to fade the actor (in milliseconds)
Returns ActionContext
publicflash
This will cause an actor to flash a specific color for a period of time
Parameters
color: Color
duration: number = 1000
The duration in milliseconds
Returns ActionContext
publicfollow
This method will cause the entity to follow another at a specified distance
Parameters
entity: Entity<any>
The entity to follow
optionalfollowDistance: number
The distance to maintain when following, if not specified the actor will follow at the current distance.
Returns ActionContext
publicgetQueue
Returns ActionQueue
publicmeet
This method will cause the entity to move towards another until they collide "meet" at a specified speed.
Parameters
entity: Entity<any>
The entity to meet
optionalspeed: number
The speed in pixels per second to move, if not specified it will match the speed of the other actor
Returns ActionContext
publicmoveBy
This method will move an actor by the specified x offset and y offset from its current position, at a certain speed. This method is part of the actor 'Action' fluent API allowing action chaining.
Parameters
offset: Vector
speed: number
The speed in pixels per second the actor should move
Returns ActionContext
publicmoveTo
This method will move an actor to the specified x and y position at the speed specified (in pixels per second) and return back the actor. This method is part of the actor 'Action' fluent API allowing action chaining.
Parameters
pos: Vector
The x,y vector location to move the actor to
speed: number
The speed in pixels per second to move
Returns ActionContext
publicrepeat
This method will cause the actor to repeat all of the actions built in the
repeatBuilder
callback. If the number of repeats is not specified it will repeat forever. This method is part of the actor 'Action' fluent API allowing action chaining// Move up in a zig-zag by repeated moveBy's actor.actions.repeat(repeatCtx => { repeatCtx.moveBy(10, 0, 10); repeatCtx.moveBy(0, 10, 10); }, 5);
Parameters
repeatBuilder: (repeatContext: ActionContext) => any
The builder to specify the repeatable list of actions
optionaltimes: number
The number of times to repeat all the previous actions in the action queue. If nothing is specified the actions will repeat forever
Returns ActionContext
publicrepeatForever
This method will cause the actor to repeat all of the actions built in the
repeatBuilder
callback. If the number of repeats is not specified it will repeat forever. This method is part of the actor 'Action' fluent API allowing action chaining// Move up in a zig-zag by repeated moveBy's actor.actions.repeat(repeatCtx => { repeatCtx.moveBy(10, 0, 10); repeatCtx.moveBy(0, 10, 10); }, 5);
Parameters
repeatBuilder: (repeatContext: ActionContext) => any
The builder to specify the repeatable list of actions
Returns ActionContext
publicrotateBy
This method will rotate an actor by the specified angle offset, from it's current rotation given a certain speed in radians/sec and return back the actor. This method is part of the actor 'Action' fluent API allowing action chaining.
Parameters
angleRadiansOffset: number
The angle to rotate to in radians relative to the current rotation
speed: number
The speed in radians/sec the actor should rotate at
optionalrotationType: RotationType
The RotationType to use for this rotation, default is shortest path
Returns ActionContext
publicrotateTo
This method will rotate an actor to the specified angle at the speed specified (in radians per second) and return back the actor. This method is part of the actor 'Action' fluent API allowing action chaining.
Parameters
angleRadians: number
The angle to rotate to in radians
speed: number
The angular velocity of the rotation specified in radians per second
optionalrotationType: RotationType
The RotationType to use for this rotation
Returns ActionContext
publicrunAction
Parameters
