kandi X-RAY | trtl Summary
Trtl is a simple 'turtle' system inspired by Python's turtle.py. It provides simple turtle drawing capabilities in Ruby, even if you're just at an IRB prompt. It leans on Tk (which used to be in Ruby's standard library but is now an external gem).

QUESTION
So I have 3 bosses and I have images for each but I don't know how to the turtle randomly select a image to use. Should I make another list to store the images and then make it randomly pick a turtle? Should I also make the turtle change right then while its hidden or should I make it change before the boss fight?

QUESTION
When I start my game it first shows the title screen and when I press Enter it goes to the character selection screen. This is intended, however at anytime if I press Enter, whether after the title screen or not, it will go to character selection.
Is there a way I can make it so that the onkeypress
only works when I am on the title screen?
I have tried to move the onkeypress
into my function that opens the title screen and I have also tried to make an if
statement that says "if it is on the title screen then my onkeypress", however neither solution worked.
How can I do this correctly? I am working in replit.

is equal to 1 needs to be done every time the Enter key is pressed.

So I'm trying to make a game similar to Stick Hero, where the goal is to estimate the correct length in order to pass to the next building. Right now I have it so the length of the path grows as the space bar is pressed and then falls down to see if the player made the correct length. My dilemma is that every time the length of the path is changed, it must be moved so it falls down correctly (touches the edge of the first building). Right now the drop_path() function determines how many times the length was changed then positions the path correctly
...ANSWER
Answered 2022-Jan-14 at 02:59Since you use shapesize()
to adjust the path, we can also use shapesize()
, with no arguments, to interrogate the current shape of the path. With that information, we can calculate where to place the tilted path:

My turtle won't move with my key press. When you remove the self.forward part, it turns just fine, but when it moves it doesn't work. How can I make it so that turtle turns while it is moving. Also, what was it that didn't work in my code before. Also, the image labeled backround isn't loading. How do I fix that? Thanks. Code:

so if RedTurtle.pos() == (220, 0):

QUESTION
I am currently making TicTacToe for a project using the turtle module. I made a list with the coordinates on where the turtle should go based on the input given by the user. After that, I made an if statement on if certain spots have been selected by the user, then the user would win. While making the if statement, I was using indexes to try to see if the User's inputs matched the actual coordinates. While checking in the if statement to see if specific cords match. I keep getting errors like:

QUESTION
Here's a clip of the code. I'm getting an infinite loop problem where it keeps repeating player turn without going to check_click()
even when the screen is clicked. Is there something I did wrong? or is there an alternative way of doing this?
ANSWER
Answered 2021-Jan-27 at 02:24'onscreenclick ()' sets up an event handler. In your case 'check_click ()'. It only needs to be called once. Also it is a method belonging to 'turtle' not 'Screen'. Try it like this :
QUESTION
I'm making a game when the user has to move the car to dodge obstacles, Everything working except I can't get the game to and end. My goal is to end the game when the block hits the turtle.
The issue is I can't get the game to detect the turtles to detect their proximity and the exit or quit command doesn't work. Also I don't think the code pasted properly so adjust the indents if it doesn't work.
...ANSWER
Answered 2021-Jan-02 at 04:28The problem is that you're re-drawing the block and thus resetting its position before you're testing the distance.
Alter the function like so:
QUESTION
So, I am a recent beginner to python and for my class I am being tasked with making a turtle race with 10 turtles that all move and should stop at the finish line. I was given directions to make a list for the turtles and have a while loop to make them move a random amount and a nested if loop to check for the winner. I am having trouble making all the turtles move at once, when I run my code, it moves the turtles one by one instead of all together, any ideas?
