Horse Race Game

[xybition]

Hey,
I need to create a horse race game. It is the question number 2, in Chapter 10 Projects, on page 276. It is about creating a horse race game, that horses move randomly and a different horse wins everytime. There are gonna be different colors of circles beginning of the each race lane, so the player can choose a horse. and if the player chooses the right horse is should say you win after the race ends. if the player does not choose the right horse it is going to say try again.

I created it, but my proffessor told me that I needed to use arrays in the race. Also she said that I needed to use randomized timing of race. The horses move randomly and a different horse wins everytime. So I thought time would be randomized but it is not enough. What else should i do? And I could not understand how I can fit the arrays in there. How can i use them in there? For what?

She said "Your coding would not take into
account the color but the position of the button I picked."

How do I fix this?

Thanks.

Go to Google and search for the following keywords:

See if you can glean any information from my drag race game that will help you with your horse race game.

I am sorry. It said question #12. I fixed it. Now it says question #2. Please someone help me solve this question. it is really important. How am i supposed to use arrays in this?

So I did the game. But still there is a problem with deciding which horse won. I think I did it the right way, and everything seems to be correct, but sometimes even if you do not choose the winning horse it will say you win, or even though if you choose the winning horse it will say try again. I am putting the game here, so maybe someone can tell me why it does that, or at least an idea.

I would suggest that you ask the professor/teacher if you could meet with her before/after school or possibly during lunch period to review arrays/lists in Alice. Tell her you are having some difficulties with the assignment. I'm sure the teacher will accomodate you.

Teachers will help if you ask them! I don't believe a teacher would appreciate my writing your assignment for you. The teacher/professor is the best solution to your problem.

Good luck,

I asked but she wont help. She just tells me what to do, which is the same thing with the question. She said we dont have use arrays now. So i am not using arrays. I cant figure out whats wrong with coding.. It looks likle there is no mistake, but still it will display the wrong message. You dont have to write it for me, but if you can give me clue like ; use if, or use while. or use this property or this function. i dont know. anyhelp :)

First I am somewhat confused now by your question(s). You say you are doing the A Horse Race Game on page 276 of the Dann, et. al. text book. To the best of my knowledge you never needed arrays to begin with in this project. The horses are already part of the world. Secondly, the project tells you step-by-step the methods and event your need to create. In your code you've created an event for each circle?: why not create a world level method, startGame with 1 parameter (obj), and then create a single event: When mouse is clicked on anything, do world.startGame obj = object under mouse cursor.

Your initital method, startGame(), should then call a method such as, setClicked passing it the object that was clicked on:
world.setClicked = obj

Then, per the project specification create a class-level Boolean variable named isClicked for each of the circles. Initialize each class level variabable to false. When the player clicks on the circle, change the appropriate circles's isClicked to true:

setClicked() might look something like this . . .
if clicked == sphere
sphere.isClicked set value to true
else
if clicked == sphere2
sphere.isClicked set value to true
else
. . . . . . .

Now you know which sphere the user chose for the winner and you don't need an array for that neither do you care about the circles color.

Now write a world level method, horseRace() and do as the instructions say, use a Do together to move all three racehorses forward a short random distance.
world.horseRace()
Do together
raceHorseGame.raceLanes.racehorse1 move forward random number (min -0, max -0.2)
raceHorseGame.raceLances.racehorse2 . . . . .
raceHorseGame.

if world.isGameOver()
/*now determine if game is over as suggested by project's specification. "Write a
function called isGameOver() that asks 'Is a horse within 0.5 meters of the finish
line?' ". .05 meters accounts for the distance to finish line is measured from center
of horsen, not it's nose. If you resized the raceHorseGame object when creating
the world you may have to adjust this distance. This function should return a true
once it has determined that the game is over.
*/
else
world.horseRace() // you are recursively calling the horseRace() method
// until the game is over.

If you are still having problems after trying these tips then let me know. If you do have problems attach your code for the above, do not send your original code. Your original code has no comments in it, plus you have several methods with no code in them and that simple makes it somewhat harder to understand what you are doing.

I hope this helps.

I got it...

thanks a lot my friend. I owe you one! If you need anything done (you know... maybe easy, but takes a long time), let me know. I'll try to be of help. Thanks again.

Good luck in your programming efforts! But always remember that it is easier for others to read your code if you COMMENT it :)

I hope your teacher was pleased with your assignment.

Ok. I'll keep that in mind :)

By the way I guess she was pleased with it since she gave me a 100.

Great job !! :D

Good luck !
