Setting up Conditional States and Triggers

Hi,

One way you could try is using variables.

1. Set the state of the Next button to Hidden or Disabled
2. Create 4 True/False variables, one for each video. Set the default value to False.
3. Create 1 True/False variable to represent when all videos have been viewed. Set the default value to False.
4. Set a Trigger on each video layer to change the video variable. For example, Adjust variable Video 1 to True when timeline ends on this layer.
5. Set a Trigger on the base layer to change the all videos variable to True when all 4 video variables have been changed to True. Adjust variable All Videos to True when the variable Video 1 changes to True, when the variable Video 2 changes to True, etc.
6. Set a Trigger on the base layer to change the state of the Next button image to Normal when the All Videos variable changes to True. Change State of Next button, set state to Normal when the variable All Videos changes to True.
