Help with Avalanche Game

[Shinkei]

What is it you are trying to achieve?
<Replace all the <> with your answers/code and remove the <>>


What is the problem you are having?
I want to make an avalanche game where objects fall down(preferably triangles) and hit the player(in this case it is a cube).
I need help on collision detection as well as objects falling randomly.

Turing:

Please specify what version of Turing you are using
4.11

Well, then you'll need two things:
1. Arrays
2. Input.KeyDown
Ever used either of those?

[Shinkei]

I have Input.KeyDown for the character
But I have no clue about the falling objects.

[Raknarg]

Well, I'll try to give you a brief overview of them, but I would suggest looking up the Turing Tutorial in the Tutorial section.
So arrays are essentially single variables that can hold more than one piece of information. Imagine it like a box with a bunch of different compartments inside. You call it like this:

Turing:

var thingy : array 1 .. 5 of int

Those numbers can be set to anything, as well as the identifier. You could have an array of chars, strings, reals, nats, or even procedures if you wanted.
Falling objects are rather simple. I'll give you a code snippet:

Turing:

setscreen ("offscreenonly") var objectx, objecty : array 1 .. 5 of int for i : 1 .. 5     objectx (i) := Rand.Int (0, maxx)     objecty (i) := Rand.Int (0, maxy) end for loop     for i : 1 .. 5         objecty (i) := objecty (i) - 1         if objecty (i) < 0 then             objecty (i) := maxy             objectx (i) := Rand.Int (0, maxx)         end if         Draw.FillOval (objectx (i), objecty (i), 5, 5, 7)     end for     View.Update     delay (5)     cls end loop

All you would have to to is have the objects constantly falling, and reset their x and y positions when they hit the ground.
FYI in case you didn't know, to access a certain element within an array, you call the variable name and a number.
ex:

Turing:

var foo : array 1 .. 3 of int foo (1) := 3 put foo (1)

So that way you can set variables inside the array. However, you can do this simply using a for loop, too!

Turing:

var foo : array 1 .. 5 of int for i : 1 .. 5      foo (i) := i * i end for for j : 1 .. 5      put foo (i) end for

This code would have an output of:
1
4
9
16
25
Anyways, hope that helps.
Again, check the actual tutorial for more info.

If you understand how to get certain properties about an object (position, length, width, etc), then collision detection will be a piece of cake.

[Raknarg]

He could just use Math.Distance instead. Wish I knew about that earlier.
Of course, thats only good for certain kinds of collision...

[apython1992]

Ahh. I don't know Turing, but yes, that would be helpful.

[Raknarg]

All I know is turing. C++ is too much work ;P

[Insectoid]

Slightly off-topic, but Raknarg, why not learn C? You need to (read: should) learn it before C++ anyway, and it's fairly similar to Turing mechanics-wise. Not a hard language at all to learn.

[apython1992]

I don't really enjoy C++ a whole lot. I use it only when I need fast code. And sometimes when I need fast code I still don't use it

[Raknarg]

Thats what Turing is for

c:

#include <iostream> int.main; {      cout << "C++ is meh." << endl;      cin (); }

or...

Turing:

put "Turing. Yay."

[apython1992]

I agree with Insectoid. The more languages you learn the better. You seem to understand Turing well enough, why not move on? Yes, C++ has an ugly "Hello, world" program, but it outdoes Turing in many more ways. Or, if you'd rather not dive in to a lower-level language quite yet, I would strongly suggest Python or Ruby.

[Raknarg]

Yeah, I'm starting to begin other stuff... After playing around with my now rediculously complex space game, I realize that Turing can be really slow I just recently got C++, and I'm starting Ruby. But this can continue somewhere else, I'm sure the OP doesn't need an insight in my life

I have the balls spawning at random now how can i make let's say a red one spawn randomly but make it very rare (power-up_

make your own thread, with the proper format
