## Scenario

If you are going to build a whole series which is used to link a lot of maps, most of the map developers would use scenario feature to link their maps together.

Normally people would follow the culture that use "**Mission complete and switch to level with ID 'A'**" to connect between levels, then used "**End mission with reason 'A'**" for last level to thank people playing or ask them to rate 5 etc.

In this tutorial, we will show you how to make them work.

### End mission scenario

Step 1: make a activation region and a trigger, and bind the activation region to that trigger.

Step 2: Set the trigger action 1 type as **End mission with reason 'A'** , then type anything you like in parameter A.

Step 3: Save the map, and test it. Normally it will show the text you had typed after the screen fades out.

### Switch map ID scenario

Step 1: same as above, just change the Action 1 type to **Mission complete and switch to level with ID 'A'**. 

Step 2: type your next map id you wish to connect in parameter A.

Step 3: Save the map, and test it. Normally you will be getting "now loading" screen and transfer to next level.
