What trigger are you using to move the object to the right only if the answer is correct? If you've got that working, the same trigger could have an "Else" action that moves the object to the left.
For example, in this situation, I'd use a T/F variable to track whether a given question was answered correctly. I'd change the variable to True on the question slide if user correctly answers the question. Then, in the trigger that will move the object to the rigth, include a condition that the variable = True.
If you're doing something like that, you should be able to add an "Else" action to the trigger, which would run if the condition isn't met (that is, the user answered incorrectly). The "Else" would move the object on a motion path that goes to the left.
Of course, there are different ways to accomplish the same thing. Which means troubleshooting is just guessing without seeing the .story file. If you upload it, someone might be able to solve the issue. Here are the best practices for doing that:
- Only include slides that are related to the problem.
- Be sure objects, layers, motion paths, and variables have meaningful names.
- If there is proprietary content, replace or delete it. For example, replace proprietary text with “ipsum lorem” text.
