Commands will be issued one per line followed by a carriage return. You can set a variable to a number between 0 and 360 and then walk on that path. The turtle can be directed with headings that correspond to a compass rose, with 0 or 360 degrees pointing straight up, 90 degrees straight to the right, and so on. In its centered, zoom-"normal" state, Logo's drawing screen shows an area of about 150 points up or down and 300 points right or left from the center. Here, ‘0 0’ is the center, or origin (no comma or parentheses here!).
Many programming systems work on the same kind of two-axis ‘xy’ coordinate plane, which we work with in Algebra as well. The right side wraps to the left side and the top wraps to the bottom. If the turtle tries to walk off onto one side of the screen, it wraps around. At the southwest corner, they are -250, -250 etc. At the northeast corner, they are 250, 250 at the southeast corner, they are 250, -250. The values of the two coordinates (normally called x and y) at the center are 0, 0. The graphics window has a coordinate system. Left 90 or lt 90 means left turn 90 degreesĬlearscreen or cs means erase all drawings. Right 90 or rt 90 means right turn 90 degrees A rotation by 360 is a complete rotation, therefore a rotation by 375 degrees is the same as 1/15 degrees.įorward 60 or fd 60 means go forward 60 steps The arguments for fd and bk are units those of rt and lt are angles that can be any integer. Except the cs command, each of these commands must be followed by one value called as its argument. The commands and their abbreviations are given below −Įither version of these commands can be used. The simple Logo Drawing Commands move the Turtle forward and backward and also turn it right or left. Once this is done, press Enter or click the Execute Button. Click a line in the history to make it jump to the respective command line, then we can make changes (if required). The command history will appear in the gray box. We can also write and run more than one command online at a time. To execute or run these commands, press Enter or click the Execute Button. We will write commands in the command line, i.e., the text box at the bottom of the Commander Window.
