the value in playerobj['bounce'keeps track of at what point in bouncing the player is at this variable stores an integer value from to bouncerate just like the bounce value for the enemy squirrelsa playerobj['bounce'value of means the player squirrel is at the start of bounce and value of bouncerate means the player squirrel is at the end of the bounce the player squirrel will bounce whenever the player is movingor if the player has stopped moving but the squirrel hasn' finished its current bounce this condition is captured in the if statement on line if any of the move variables is set to true or the current playerobj['bounce'is not (which means the player is currently in bounce)then the variable should be incremented on line because the playerobj['bounce'variable should only be in the range of to bouncerateif incrementing it makes it larger than bouncerateit should be reset back to collision detectioneat or be eaten check if the player has collided with any squirrels for in range(len(squirrelobjs)- - - )sqobj squirrelobjs[ithe for loop on will go run code on each of the enemy squirrel game objects in squirrelobjs notice that the parameters to range(on line start at the last index of squirrelobjs and decrement this is because the code inside this for loop may end up deleting some of these enemy squirrel game objects (if the player' squirrel ends up eating them)so it is important to iterate from the end down to the front the reason why was explained previously in the --when deleting items in listiterate over the list in reverse|section if 'rectin sqobj and playerobj['rect'colliderect(sqobj['rect']) player/squirrel collision has occurred if sqobj['width'sqobj['height'<playerobj['size']** player is larger and eats the squirrel playerobj['size'+int(sqobj['width'sqobj['height'])** del squirrelobjs[iif the player' squirrel is equal or larger than the size of the enemy squirrel it has collided withthen the player' squirrel will eat that squirrel and grow the number that is added to the 'size
