SlotMachine class
A class that creates the slot machine.
It currently only creates slot machines with 5 slot lines, 10 images each. The slot machine is visualized through 2 DOM elements. canvasEl shows the slot machine itself, with rotating slots. resultEl is a span element that automatically populates with the current outcome in real time.
The SlotMachine is single-serving, i.e. it cannot be rolled more than once.
Constructors
- SlotMachine(num probability, {Result predeterminedFirstResult, AnimationFrameFunction animationFrame, bool rerollable: false, String rerollEffectDescription})
-
Create a slot machine animation with given
probabilityof success. [...]factory - SlotMachine.fromProbability(num probability, {Result predeterminedResult, AnimationFrameFunction animationFrame})
-
Create a slot machine animation with probability of success (of the whole
machine) being
probability.factory
Properties
- allowCriticalFailure → bool
-
Whether or not to allow this slot machine to return critical failures.
final
- allowCriticalSuccess → bool
-
Whether or not to allow this slot machine to return critical successes.
final
- canvasEl ↔ CanvasElement
-
The canvas element that this library creates and that should be added
to the DOM by the library's user.
read / write
- hashCode → int
-
The hash code for this object. [...]
read-only, inherited
- rerollable → bool
-
Whether or not this SlotMachine allows rerolling. If so,
rerollEffectDescription must not be
null.final - rerollEffectDescription → String
-
What to show to user as the 'cost' of reroll. [...]
final
- rerollEl ↔ DivElement
-
Element that the slot machine populates with buttons when reroll
is in order.
read / write
- resultEl ↔ SpanElement
-
The result element that this library updates with current result (i.e.
what the slot machine would output if it was immediately halted, frozen
in current state). [...]
read / write
- runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited
- width → int
-
The width of each reel in pixels.
final
Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
inherited
-
play(
) → Future< Result> - Start the slot machine session. This will roll the reels to completion once and will return the result of the first roll. [...]
-
rerollIfNeeded(
) → Future< SessionResult> - This method returns the final SessionResult. It may allow the user to reroll if that is needed.
-
roll(
) → Future< Result> -
Start rolling the slot machine. Returns with the text of the result.
@Deprecated('Use play() instead')
-
toString(
) → String -
Returns a string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator. [...]
inherited
Constants
- reelCount → const int
-
The number of reels (vertical lines) per each machine.
5 - symbolCount → const int
-
Number of symbols in each reel.
