This picture shows that the Tkinter’s coordinates (red) and the turtle’s coordinates (blue) are different. You can determine the mouses current position by calling the pyautogui.position() function, which will return a Point named tuple of the mouse cursors x and y. Unlike in mathematics, the Y coordinate starts at 0 on the top and increases going down. The X coordinate starts at 0 on the left side and increases going right. self.x and self.y aren’t used alone in self.t.setposition(self.x-300, (self.y*-1)+300) because the origin of the turtle’s screen is in the middle while the event’s origin is on the top left corner of the screen. Locations on your screen are referred to by X and Y Cartesian coordinates. Take note that x and y are manipulated in the last line of run(). This program simply moves the turtle with the cursor. (The “Motion” in screen.bind is surrounded by angle brackets) This event argument contains the mouse coordinates.Īn example of func would be: def func(event): The function func accepts an event argument.
To bind the mouse to the screen, do screen.bind('', func). The variable screen is the Tkinter object. Next, with this variable, make another variable: screen = wn.getcanvas(). getpos() get the mouse cursor position getpos() -> (x, y) Returns the x and y position of the mouse cursor. Make a Screen object like this: wn = turtle.Screen().
The X coordinate starts at 0 on the left side and. Therefore, we can use Tkinter event binding to get the coordinates of the mouse on the screen.įirst, we need to retrieve the canvas from the screen. The Screen and Mouse Position Locations on your screen are referred to by X and Y Cartesian coordinates. Turtle is a module that is based on Tkinter’s Canvas.

In this tutorial I will show you how to do that.Ī turtle program where a line goes from the origin to the mouse Tkinter Binding You can also bind the keyboard’s keys to your program using this method. Getting the mouse coordinates of a turtle is useful if you want to make the turtle follow the mouse.
