So what's happening? We're giving all the turtles the same set of instructions. Okay, now we made our turtles, let's tell them to move exactly like before. Where are the turtles? Try running that command again. Why don't we ask them to move? ask turtles Д«ut what if we don't want them on top of each other? Okay, let's try this again: clear-allД¬reate-turtles 2 clear-allДo you notice where the 2 turtles are? They are right on top of each other. Okay, now let's clean up that mess we drew. We can also tell the turtle to move backwards and to the left. This is useful later when we have very slow animations.

Currently it's at normal speed, but if we move it to the left, we can make it slower. Move the slider near the top to slow down the speed. Very pretty, isn't it? Whoa, what just happened? Why don't we watch that again in slow motion. Something like: clear-allДЄsk turtles right 60 ] ] We can even keep telling the turtles to repeat what they're repeating. Note: if you make a mistake by giving the wrong instruction to the turtle, you can reset and start again by running: clear-all What shape does this look like? Why don't we complete the shape? What instructions do we need to give to complete the shape? Why don't we look at what we have so far? ask turtles ДЄlright, why don't we tell this turtle to repeat the last instruction 3 more times? ask turtles ] We can combine the 2 instructions to one line as follows. It's especially useful if you remember how big the angles of the shape are. Now let's ask the turtle to move forward 5 steps and then turn right 60 degrees. To see a list of shapes, you can run show shapes We can also ask the turtles to change their shape or size.

We are going to ask our turtles to draw underneath them as they move. This is how you make a turtle: create-turtles 1 Select the textbox at the bottom of the Command Center to input commands. Open NetLogo and select the Interface tab.
