How do you set the turtle angle in python?
I'm creating a function that will cause a giraffe to move in a certain direction and distance (don't ask). Show If the user types "west" in the parameters, the turtle should move west however the direction is. But the turtle's angle changes every time, I can't fix a value for my turtle to turn to go a certain direction. I need to set the angle to, say, 90 so that it can move East. I can't find useful functions for this purpose. I tried to use Notes on using Python's turtle built-in commandsTurtle graphics with |
degrees() | radians() | reset() |
clear() | tracer(flag) | forward(distance) |
backward(distance) | left(angle) | right(angle) |
up() | down() | width(width) |
color(*args) | begin_fill() | end_fill() |
setheading(angle) | window_width() | window_height() |
position() | setx(xpos) | sety(ypos) |
goto(x,y) | heading() |
degrees()
Sets the angle input method to degrees. All following angle inputs are assumed to be degree measures. This is the default setting.
radians()
Sets the angle input method to radians. All following angle inputs are assumed to be radian measures.
reset()
Resets everything to the default values, and clears the canvas. After a call to reset
, the canvas will be in
exactly the same state as it was when the import command was called: you will have a blank canvas will the turtle (colored black with fill set to unfilled) pointing to the right at the center (heading = 0.0).
clear()
Erases the entire canvas and redraws the turtle. Does not move the turtle.
tracer(n=None, delay=None)
Turns turtle animation on/off and set delay for update drawings.
If non-negative integer n is given, only each n-th regular screen update is performed. Can be used to accelerate the drawing of complex graphics. When called without arguments, returns the currently stored value of n. Second argument sets delay value (see delay()).
Turning the turtle off makes the turtle disappear and makes drawing MUCH faster. Drawing commands are still executed without the turtle, and lines are still drawn when the turtle is moved. Use up
and down
to turn drawing on and
off, or just use the setx
, sety
, or goto
functions to move without drawing.
forward(distance)
Moves the turtle forward distance
, drawing a line behind the turtle. The line will be drawn even if the turtle is turned off.
backward(distance)
Moves the turtle backward distance
, drawing a line along the path taken. The line will be drawn even if the turtle is turned off.
left(angle)
Turns the turtle left by angle
. If degrees
has been called (the default), angle
will be used as a degree measure; if radians
has been called, angle
will be interpreted as a measure in radians.
right(angle)
Turns the turtle right by angle
. If degrees
has been called (the default), angle
will be used as a degree measure; if radians
has been called, angle
will be intrepreted as a measure in radians.
up()
Stops all drawing. Until down
is called, nothing will be drawn to the screen. Cursor movement will still take effect, however.
down()
Resumes drawing after a call to up
. Commands between the up
and down
statements will not be drawn, but commands after the down
statement will appear as normal.
width(width)
Sets the width of the line drawn using the forward
and backward
commands.
color(*args)
Changes the current color. The current color is used for drawing lines using forward
and backward
, as well as for filling shapes when end_fill()
is called after begin_fill()
. The color can be given as a single color string (as in color("blue")
, color("chocolate")
, color("peru")
, color("#a0df00")
, or color("#1dead1")
). A three-tuple of rgb float values (as in color((0.1,0.5,0.9))
or color((95/255., 12/255., 9/255.))
) can be used.
begin_fill()
Used to fill shapes. First, call begin_fill()
, then
proceed to draw the outline of the shape to be filled. After the shape is done, call end_fill()
. A line will be drawn from the current turtle position to the position of the turtle when the begin_fill()
command was called, and the resulting polygon will be filled with the current color (the color of exterior lines will also be changed). If any interior angle in the resulting polygon is greater than 180°, however, the resulting filled polygon will only include the first two line segments after the
begin_fill()
statement, forming a triangle.
