In this task, we are first going to add the pen extension. So we're gonna go down to the bottom left, press on the Extensions button and add the pen. So now we can see all of the pen commands. We are gonna add an event block here. I'm going to use the flag to make my setup code to get the project ready to start drawing. So I'm going to need the pen down, set the pen colour. I'm going to need Erase All to rub out all the lines, and then I think also a motion block. I'm going to use the go-to block, and we've learned that if you put zero in both of these values, it will put the sprite right back to the centre of the screen. So which order do these blocks go in? Well, you might have to test out a few different combinations. I'm going to go with Erase All first, then move to the centre, set the pen colour, and then put the pen down, ready to draw. Let's test that out, I'm going to press the flag. Now, the drawing commands are working well, pen down and change the colour are both working. When I press the flag to erase, let's see how that works, I'm going to press the flag. Now, it did leave a line behind, and that's because the order of my sequence of blocks isn't quite right. After the lines were erased, the sprite then moved to the middle, which drew the line. So I'm going to change this around. I'm going to first of all, move the sprite to the middle, then erase the blocks. That should work better. Let's test it this time. There we go. My setup code is working correctly for my programme.
