[CS 61A SU26] Ants Problem Getting Started

[00:00:02]hi welcome to the getting started video for problem 10 of ants so we want to make it more interesting we want to add water to our game so currently we only have two types of places Hive and just like a basic place but to make things more interesting we're going to create a new type of place that we call water um so only an insect that's waterproof can survive in water and we want to figure out if an insect is waterproof or not so we're going to create a new attribute to tell if they're waterproof um so yeah let's dive into this so we want to create a new class attribute in the insect class and we're going to initially set this to false so essentially what we're saying is that um originally all insects are like not waterproof so we're gonna to override or to create a class attribute we're going to go to our insect class and we're going to create that attribute so we're going to create is waterproof um and remember that it's such false Okay cool so we've created our attribute let's see what we want to do next um well since bees can fly they are waterproof right they can avoid water so we're going to set the is waterproof attribute to true so let's go to our B Class okay so you see we have this section right here for overwriting class attributes so let's override it so we're going to override our is waterproof and remember that this attribute right here is waterproof is going to be inherited and that's because B inherits from insect um so originally is waterproof is set to true because that's what we did in or sorry is waterproof is set to false because that's what we set it to an insect but we want these to be waterproof so we're going to set it to True here okay so our class attributes should be fine now let's move on to the next step so the next thing we want to do is we want to implement add insect so this is a method within the water class so what essentially what we want to try to do is we want to add the insect to our water place or to the spot on the board we don't care yet about if it's waterproof or not but we're just going to add it if the insect is not waterproof we want to reduce the insect's Health to zero so essentially the insect is going to die rest in peace um so let's figure out how we want to do this okay um and one what was this method called okay odd insect um and it was in our water method for a water class um okay there we go okay so essentially we have two steps right the first is that we want to add or insect so let's think about this what method do we currently have um that allows us to add an insect to a spot and notice that like our add insect method takes in insect um so what method can we use that will add a given insect in this case insect to our place I'll let you think about that but as long as we call that method we can assume that we added the insect to the place correctly then our second step is that we want to check if the insect is waterproof if it's not waterproof then sadly or insect is not really going to be alive anymore essentially if it's not waterproof we want our health to be equal to zero so I'm going to ask you another question what method do we currently have that can reduce an insect's Health to zero what method can we use for this okay so essentially this is the outline of our problem and just to recap what we did we wanted to determine if oh an insect was waterproof or not if it can survive in water so we created an attribute to tell us that if an insects um is waterproof attribute is set to true then it is waterproof um and if an insects is waterproof attribute is set to false then it's not waterproof so that could be really helpful for checking if the insect is waterproof or not then we want to be able to add that insect to a water place essentially so we want to add our insect and like I said let's figure out what method we can use for that and that will really help you out once we add our insects we want to check if the insect is waterproof or not and that's where the attribute we created comes in handy if it's not waterproof then we want to reduce that insect's Health to zero um and once again I'm going to ask you what method can we use for this and that's pretty much it if the insect um is waterproof we don't have to do anything we only need to reduce its Health in the case that it's not waterproof so hopefully this helps you with the problem and good luck
