DDR Problems

[Savage Reindeer]

What is it you are trying to achieve?
I am about half a year into learning Turing. So I am relitively new. I am making a DDR game. My current goal is to have a block (called arrowup) move up the screen and assing a value of "perfect", "good", "bad" or "miss" to the variable ans. I also want the program to generate blocks (or arrows) in four columns.


What is the problem you are having?
I am having two problems.

1) The block moves up into the three areas. If you hold down the up arrow, the value of ans will change for as long as that arrow is held down. How do I have the game take whatever value it is when the arrow is pushed?

2) I have no idea how to generate the blocks. I thought I would use arrays, but beyond that I have no idea.


Describe what you have tried to solve this problem
As for problem one, I tried making a loop inside a loop, that exited when the up arrow was pressed. the only problem was that it got stuck in the loop (displaying a blank screen) until the up arrow was pressed and then continuing later.

Like I said before, I have no idea how to solve the second problem passed the fact that a should use arrays.


Post any relevant code

Do you know Object Oriented Programming? If so, make a block class that contains a boolean variable stating whether an attempt has been made to make points off of that block. If an attempt has been made, disable all further attempts.

However, if you are not familiar with OOP, I suggest that once a button has been pushed, you set a variable that declares whether the button is up or down to down. Then, make them raise the key again before setting the variable back to up and allowing them to score from it. You can check that a key is up using

Turing:

var chars : array char of boolean Input.Keydown(chars) if not chars('a') then     %'a' key is not down

Here's pseudo-code to help you develop your idea. I believe this should work.

code:

if box > maxy then     box_y := 0     rand := Rand.Int(0,4)     box_x1 := rand * spacing_between_boxes + offset_from_left_of_screen     box_x2 :=  rand * spacing_between_boxes + offset_from_left_of_screen + length_of_box     Draw.Box(box_x1,box_y,box_x2,some_var,some_col)     box_y += 5 %moves box end if

If you go here http://compsci.ca/v3/viewtopic.php?t=20842, I have a Key module that you may like to look at. I have made a key hit function that can solve problem 1, and problem 2 , you will need a couple arrays, and array 1 to 4 (assuming there are 4 arrows ) of the x, a variable for the velocity, an array for the max num of arrows for there y position and an array for the max num of arrows for the type. (if type 1 then draw at x (1)) If you need me to xplain more clearly I can help at any time.

I am familiar with the concept of OOP, an object is like a car, and its properties are like its parts, and you can change the parts to make different types of cars, but they are still a car.

Anyway, could someone direct me to a tutorial for OOP?

I tried using nested if statements. It didn't seem to do anything.

Turing:

function hit (chars : array char of boolean) : string     %If the top side of the box is below the top side of the perfect area     %and the bottom of box below the bottom of the perfect area     if boxup_y1 < perfect_y1 and boxup_y2 > perfect_y2 and chars (KEY_UP_ARROW) then         if not chars (KEY_UP_ARROW) then %If the up arrow is not pressed down             result "perfect"         end if     else %If the up button is never pressed         result " "     end if     %If the top side of the box is below the top side of the good area     %and the bottom of box below the bottom of the perfect area     if boxup_y1 < good_y1 and boxup_y2 > good_y2 and chars (KEY_UP_ARROW) then         if not chars (KEY_UP_ARROW) then %If the up arrow is not pressed down             result "Good!"         end if     else %If the up button is never pressed         result " "     end if     %If the top side of the box is below the top side of the bad area     %and the bottom of box below the bottom of the perfect area     if boxup_y1 < bad_y1 and boxup_y2 > bad_y2 and chars (KEY_UP_ARROW) then         if not chars (KEY_UP_ARROW) then %If the up arrow is not pressed down             result "Bad"         end if     else %If the up button is never pressed         result " "     end if     %If the box is not in any area     if boxup_y2 > bad_y1 or boxup_y2 < bad_y2 and chars (KEY_UP_ARROW) then         if not chars (KEY_UP_ARROW) then %If the up arrow is not pressed down             result "miss"         end if     else %If the up button is never pressed         result " "     end if end hit

Follow the order of your code in that function it will check the first if statement if it is true it will follow after the then

if it is false it will exit the function with the result " "
