In some demos, you may need to randomize multiple transitions from the same scene. You are likely to do this in scenes that involve unpredictable results, such gambling, a player hitting a baseball, or randomly spawning one of several monsters.

For example, to reflect the randomness of a possible outcome in a baseball game, you can create multiple transitions with different probability in your demo, for example, 40% Home Run, 30% Double, 15% Single, 10% pop out, and 5% ground.

With randomized transitions, the demo will move to an alternative flow somewhat at random rather than as a result of a predefined transition logic. To accomplish this, you need to set the appropriate probability values fro each alternate transition.

What Your Need to Know

Here’s what you need to keep in mind about setting probability:

  • The probability values are decimals between 0 and 1, with 1 indicating that the transition will occur with 100% probability and is the only valid probability.
  • The total sum of the probability values for multiple transitions is not required to equal 100%, as Studio tallies the values you enter for each alternate transition and calculates its percentage accordingly.
  • If you enter the same value for each transition, each will have an equal probability. For example, if you enter .33 for each of three possible transitions, each will have 33.33% probability.
  • To increase the likelihood of a specific transition, for example, to offer the user an easier, winning path, enter a greater decimal value for that transition and lower decimal values for the others. 

How to Randomize Transitions
  1. Go to Scenes and select a scene where you want to add randomized transitions.
  2. Go to Events & Actions and in the Transitions section, click Add .
  3. In the Transition menu on the right, in the Probability field, enter a decimal between 0 and 1, for example, .4, .3, .15, .1, and .05 for 40%, 30%, 15%, 10%, and 5% respectively in the example above.

    Tip: You can also randomize transitions using trigger conditionals, for example, as described in Trigger Use Case 2.

  4. Make the appropriate selections in the remaining fields.
  5. Repeat steps 3 and 4 for each transition in the flow.
    The respective Move to Scene blocks in the Events & Actions panel reflect the probability you set for each transition.

  6. Save the project.
  7. (Optional) Click Path View to see the transitions you have defined.
    In Path View, the transitions for the use case above should appear similar to the ones shown below.
