AI for Good – MINECRAFT EDUCATION

Okay everybody welcome back to learn with  minecraft education and today we are going   to be doing a walkthrough for the Minecraft hour  of code now this is a really good I should explain   what I’m doing here right so let’s go to view  library let’s go to lessons let’s go to computer  

Science and click hour of code there we go now  this some hour of code and create world okay   now this particular lesson is supposed to be an  introductory lesson on to how to move around in   Minecraft there’s npc’s in there that will  explain to you where to go what to do so you  

Can kind of leave the students alone with this  one and hope that they make it through although   my experience is not always the case so this is a  little tutorial that you can use to help you get  

Through and also show you the kind of approved  way to complete some of these tasks because not   every task is some super intuitive all right  so I’m current quest is coming up there in the   left so that’s saying go talk to the researcher  so it’s pretty clear straight ahead we need to  

Move our way forward we’ve been spawned in this  world here and we need to make our way over here   to get through the gate here we go right-click me  so it’s teaching us to talk to NC NPCs welcome to  

The research center here you will learn AI and  coding to prevent to fires your first task is   to use coding to open this gate press C to start  coding now depending on the age of your students  

They may or may not actually read this and just  walk up to the gate but we do need to encourage   them to press C and it is actually popping up at  the bottom so press C to get coding now for each  

Tutorial it will load its own there we go open the  gate it will load its own set of coding so here we   literally have the two bits of code that we need  and then we press where it says on start that  

Means pressing this particular button here so we  press that and there’s the gate all opened up okay   now current quest to talk to the engineer this is  the agent you can program the agent like you did  

With the gates radiation to move 3 steps forward  and stop on the marker all right then again it’s   going to load up just the blocks that we need  very simple stuff in a blink and we also get  

This little help thing at the top so if we click  here it literally tells us what to do track the   8 age of move forward block from the toolbox into  the on start block and change the number of steps  

From 1 to 3 so do remind your students that they  can access this up here it will tell them exactly   what to do so you drag it on change it to 3 press  start there we go in the agent disappears through  

The next gate so let’s have a chat with the  researcher which is our current quest the agent   needs to collect data about flammable materials  that could pose a fire hazard code the agent to   move 4 spaces forward towards the dry brush and  then analyze the data ok all right so see so it’s  

Gonna move forward and analyze this and it should  just give us the blocks that we need agent analyze   ok again if we just click here we pop in the agent  analyze forward last fine so he was moving forward  

Four and then I’m analyzing whatever is in front  of him we go through the gate now we need to go   up the ladder and talk to the technician let’s  take the long path look over the edge of the  

Building and you will see the agent training  maze don’t worry you can’t fall off choose a   path button below and movie agents through the  maze to reach the drybrush and analyze it so   let’s take the long path or not what rights the  edge we can’t fall off so here’s my ranger down  

Here we need to get our agent over here alright  so forward to turn left forward four turn right   four to turn right forward four and so on so let’s  break this down so you go forward to turn right 44 okay

Right so we’re gonna move the agent forward to  and what we’re trying to do is just look if we   can kind of see down here I suppose that’s where  coding that’s helpful so gonna move forward to and  

Then turn agent left then we’re gonna move forward  for and turn the agent right which should take us   to here then forward to then we’re going to turn  right because we should be in this little square  

Here then I’m gonna fall on to three think that’s  four let’s give it a go move forward for now I’m   going to turn left then we’re going to be forward  on to now we’re going to turn left I’m gonna move  

Forward another two should take us to here and  then we’re going to turn right forward another   two like it’s a long path isn’t it forward  another to which it takes to here turn right   again you should take us to here then turn then  move forward one and turn left move forward to  

I think and analyze forward kind of rushing a  bit there but let’s see there he goes following   out the instructions and this is teaching us back  those blocks and get it all done in one we could  

Move him forward and turn then code some more and  codes and more and code some more but why not do   it all in one go if we can see the path and which  way the turns are and how many blocks there are  

That we can do that all right over to the ladder  now I had some students actually struggling to   get down this ladder so do you mind that they  just walk up to the edge of the ladder right at  

The ladder and then actually let go no W a s or D  at that point just to drop down to the bottom so   then we actually walk through the path that we’ve  just taken right so there’s our open gate and the  

Current quest is go down the ladder and find the  head of research fire Research Center this way all   right and there’s the head of research waiting  for us hello teaching the agent to predict the   fire hazard is our best tool for prevention come  inside and the AI specialist will assist you in  

Training the urgent line current quest talk to  the AI specialist this computer will help teach   the agent about plants that are fire hazards  watch the images on the monitor if a plant   looks yellow and dry it’s a fire hazard so press  the yes button if a plant looks green and healthy  

It is not a fire hazard so press the no button  okay so this one’s green it’s not a fire hazard   so we’re gonna right click on the note that one is  so we right click on yes and the idea is that we  

Are just training the agent to recognize what is  a potential fire hazard and what is not so we’ve   completed this quest the next one says talk to the  scientist and he’s just over here let’s see what   he’s got to say to successfully prevent fires the  agent will need to remove dangerous plants from  

The area now let’s put our training to the test  code the agent to destroy all the plants that   pose a fire hazard exit the chat window to start  coding I’d say close this is the agent so press C eliminate all the hazards so plants  are going to pop up in front of the  

Agent and we need to program the agent to  destroy only the fire hazards now we’ve   we’ve we’ve told him already what the  fire hazards are so we don’t need to do   that so let’s click here to show hint  drag the agent destroy forward inside  

The box inside the if block to make sure  the agent destroys all the fire hazards okay so agent detector I brush forward then we want to destroy okay so if he detects  dry brush forward then agent destroy forward  

And obviously if he doesn’t detect a fire hazard  they’ll be no destroying and he will keep doing   that until the hazards remain all right so as  long as this has a difference of him he will   destroy them so let’s click Play destroying fire  hazards and ignoring the non fire hazards which  

Is exactly what we want so the idea is that now  this agent is trained to go out into the field   and start clearing out fire hazards there we go  start clearing out fire hazards in the real world  

Next quest is talked to the analyst what’s  he got to say using images the agent can now   detect where the fires are like to start code  the agent to alert the team if a potential fire  

Hazard location is found on the computer monitor  fine so let’s press C let’s have a look see what   we’ve got we’ve got an agent looking at screen and  we want the agent to recognize what the fire has  

It is another team okay so drugged the alert team  block inside the if hazard found block so that the   team can be alerted so got here when we click the  green button while the agent looks for hazards if  

A hazard is found we’re going to alert the team  all right so the agents can sit there looking   at the screen and as soon as it sees a a hazard  it’s going to tell us there we go so wait for  

And see something on the screen that looks like a  hazard there we go and the abeler to the team and   the helicopter is flown in ready to take us over  to the location that the agent has identified so  

We’ll talk to the fire captain I probably how  quickly the agent learn to predict fires we   need to hurry to this location at the risk of  fire let me know when you’re ready to go if I  

Can strike at any moment let’s go right so we’ve  whizzed over to this location the agent found for   us and there is a fire hazard clearly over here  and what we want the agent to do is get rid of  

These bits of dry brush and leave the leave of  stuff that isn’t a hazard okay so current quest   talked to the fire captain I just got a message  from the command center there’s a storm rolling  

In with a high chance of lightning we’ll need to  start clearing the area of dry brush before it   gets here have the agent clear that line of dry  brush to remove a fire risk okay so let’s have a  

Look down here and press see save the village  they wanted to move forward and do that okay pricking your agent to destroy the fire hazards  in a row click the play button to run your code   in-game all right so we’ve got some code here  really Wildfire hazard remained do an if dat agent  

If detect dry-brush forward then obviously we want  to destroy okay agent destroy forward if we detect   it but we also want the agent to move forward  and ignore the potential non fire hazards okay   now this is a pretty good opportunity to take a  look at something that’s supplied with this lesson  

That isn’t always easy to find on the Minecraft  Education website so I will attach a link to it in   the description but most of the lessons have these  solutions PDFs like this one so let’s scroll down   solutions here let’s scroll down to saving the  village right and we want yeah that’s it isn’t  

It save the village fine so activity 7 save  the village well has a drain if the agent tech   detects drybrush forward then destroy it and move  forward by one so the idea is that the agent will  

Move forward by one and if you detect dry-brush  you’ll destroy it and if it doesn’t he’ll just   move forward by another one sounds reasonable so  let’s go back to minecraft and get that set up now  

That solutions page of course you can use there  you go you can use for your students if any of   them are particularly struggling you’ve got a lot  of students okay so the Lightning’s coming in you  

Can attach that PDF you send that work to students  or even have it displayed so in the classroom we   can print a couple of them off and have them lying  around ok there we go so the fires come it is kind  

Of a fire break there to stop the fire spreading  too far you completed the hour of code now look   for bonus activities in the village talk to the  firefighter great job you and your agent were able  

To clear the fire hazards before the storm came  and save the village while you are here wanting   to help restore the era by planting flowers and  spawn animals explore the village for more coding  

Activities you can try with the agent we can take  a picture there if we want to now I’m we can get   involved in some there we go that was our picture  we can’t get involved in some reforestation activities in here it’s the agent so we’ll  proceed to code the agent and we should  

Reforestation process so this shows us how to as  we are walking around be planting trees around   us and again let’s go ahead and look at the  solutions page for this one play a walk place   and then we can place just grass just a grass  block there immediately below us so 0 minus 1  

0 and spawn an animal at 0 0 0 okay so right  exactly where we’re standing only when we’re   walking so let’s go ahead and do a little bit of  that on play a walk I’ll get rid of this on play  

A walk place a grass block at 0 minus 1 0 and  spawn an animal at 0 0 0 that’s a close this we need we do need to do onstart of course we do  all right so let’s prop the ins on start back in

Ok so we are putting chickens down and some nice  bits of grass we are basically reforest in the   area and we’re getting rid of the fire hazards  now the students will obvious obviously find this   very amusing and you can change these two trees  if you like and you can change the animals too  

You know dolphins or Paris or something it’s gonna  entertain the students even more no doubt ok we’re   planting see we’re planting trees trapped down in  the ground so we want to change the coordinates   here for trees at least we want to change them  to zero don’t we so there they’re not planting  

Underground ideally and well you know it our  burnt out village is looking like a tropical   paradise we’ll have parrots and chickens and  grass and trees all over the place and the   students will enjoy I’m having a play around  with this get them to have a look around the  

Village there are some other activities and later  on in this series we’ll also look at the coding   town which has a series of different challenges  that these students can partake you know okay   now I’ll leave the link for that solutions PDF  in the description to this video do take a look  

At it please it’s not always obvious the best  way to do these for example the previous task   you could have got the agent to literally program  in and take two steps and destroy it destroy some  

Brush just by looking at the order the sequence  of the fire hazards but of course that’s not how   we want to do it want to automate the agent so  it does it by itself so do take a look at those  

Solutions pages but that’s it for now thanks  for tuning in do like and subscribe and so that   you can keep track of all the different  various lessons are going on thank you
