Getting Ready

Before we can get started with our AI, we need to perform some quick housekeeping tasks.

First, go ahead and update the Gate Check # on line 3 (just like we have on all of the other gate checks).

Second, we need to make sure that the values that you use in your simulation are similar to the ones we will be using in the competition. Check your code to make sure that:

• gravity is set to 0.08
• the rocket's up thrust during the Boost phase is 0.35
• the rocket's right thrust during the Boost phase is 0.25
• the rocket's width is 50
• The boat's width is between 100-140

Finally, we need to modify our main animation loop so that it supports AI training/learning. In the AI block, we learned that we need to expose our AI to many different scenarios in order to train it properly. Why? I'm so glad you asked . .

Once you have completed the above steps, go to the "else" statement in your main animation loop. As a reminder, this code executes every time a simulation run ends (i.e., when is_simulation_over() returns true). Modify the code in the else statement so that it does the following:

• Calls analyze_results()
• Increments the number of runs counter by 1
• Determines whether or not to create a new simulation scenario (a new random terrain):
  • If (number of runs == number of runs per scenario), generate a new scenario and reset your runs counter to 0. We cannot overstate how important this is.
  • Otherwise, reset the simulation
