Turing Mathematics

[Witchcraft]

Hey,
So I just started a nice big turing project to sum things up before I move onto learning Java. My idea is to make a pirate cannon game (kind of like the one from math circus). Well I'm just working on the rough stuff, and I got a ball to shoot up in a parabolic arc that has a vertical stretch depending on how long you hold down the mouse. Now my problem is that pictures can only be drawn on pixel values (which are always ints), but if I use a verticle stretch that is not an int, (such as 3/2) then I will get real numbers as the y values, and so the cannon ball cannont be drawn at that coordinate. This same problem would occur for vertical compression as well because division is even worse for giving you whole numbers as a result. How do I fix this problem? Do I convert a real to a int? The cod is posted below.

Turing:

%This is a pirate game, with several mini games in it var cannonx, cannony, stretch, window : int %cannon x/y, and parabola vertical stretch window := Window.Open ("graphics:800;800,position:center;center,nobuttonbar,offscreenonly") cannonx := 0 cannony := 0 stretch := 0 loop     if Mouse.ButtonMoved ("down") then         stretch := 1     end if     exit when stretch = 1 end loop loop     exit when Mouse.ButtonMoved ("up")     delay (500)     stretch := stretch + 1 end loop for i : 30 .. 100     cls     cannonx := i + 1     cannony := -1 * stretch * (cannonx - 50) ** 2 + (stretch * 400)     if cannony < 0 then         cannony := 0     end if     Draw.FillOval (cannonx, cannony, 5, 5, black)     View.Update     delay (50)     exit when cannony = 0 end for

Mod edit: Working syntax tags added.

sorry I tried to get my code to appear as it would in turing, but I'm new to the forums so it didn't work out. How is it done?

round() % rounds a number according to the one's column, should work for what you want

code:

[syntax="turing"] %code [/syntax]

thanks a lot, got it to work

make sure you use 'perfect' collision detection, or if the ball is moving too fast, it will go through the walls. Look it up in the tutorials (it is rather complicated)
