In this part of the task, I'm going to show you how to change the project to use the new controls. So, I'm going to test out these blocks and improve them. So, the first one is when D key is pressed. And when I press that, the sprite moves down. So, even though that does make sense, I'm going to change it to be even clearer. I'm going to use the down arrow. So now, when I use the down arrow on the keyboard, the crab will move down. The next one is the R key. So, if I tap that on my keyboard, the crab moves right. I'm gonna update that to follow my plan. So, I want it to be when I press the right arrow on my keyboard. That's great. You can see I'm using the green flag here to reset, just like the note says. Let's look at another one. When the U key is pressed. So, let's test out the U key. Sprite's moving up. So, I'm gonna change that to the up arrow. Moving to give a bit more space there. Now, we're missing a direction. Did you notice that? So, I'm gonna need to add another event block. I'm going to get the when key pressed block. Drag it into that space and change it to be the left arrow. That's correct there. Remember I need the point in direction. And helpfully Scratch gives you this little diagram to help you find the right direction to point your sprite. So, left is the minus 90. And then, we need the move steps block. So, just make some space for it there. Move 10 steps. Let's test that out. I'm gonna press the left arrow. Yep, so now, I can make my crab move in all four directions. Excellent. The next thing is to look at the other programmes here. Now, I was changing programmes, but sometimes it's easier to get rid of code that you don't need so that you've got space to build your own code. So, I'm gonna start with when the sprite clicked, because in my plan, when you click on the sprite, it changes costume, so I'm gonna test that now. There we go. My crab changing its costume when I click on it. And then, I'm going to need my turn right and turn left. 'Cause I haven't got them in my programme yet, I'm going to use when key is pressed to those as well. I had an idea that the turn right could be E for East and the turn left could be W for West. Let's test those out. There we go. Turn left and turn right is also working. I'm going to leave the green flag code because it resets my sprite.
