What is it you are trying to achieve?
run multiple animations at once

so basically i have an animation goign but i want to run another animation while this one is running so that hteir working at hte same time, is there a way i can do this? i cant seem to figure it out


Please specify what version of Turing you are using
4.1

Post your code on here, we need to see the problem first Razz

Don't think of it as running multiple animations at the same time, but as one large animation. If that doesn't help, well, I'm trying to dig up a tutorial. I know we've got one somewhere.

Turing:


View.Set ("graphics: 1100, 600")
View.Set ("offscreenonly")

var xx : int
var yy : int


procedure Snow
    xx := Rand.Int (1, 1100)
    yy := 599
    loop
        yy := yy - 1
        Draw.Fill (1, 1, 16, 44)
        Draw.FillOval (xx, yy, 2, 2, 0)
        delay (5)
        View.Update
        Draw.FillOval (xx, yy, 2, 2, 16)
    end loop
end Snow




thats what i have atm, i need to run that a bunch of times; ik that to make snow you normally do it another way but i couldnt figure it out

i dont think you need a procedure, but this is what id do, make a loop with a random x than set yy to the same thing within that loop, then make another loop within that loop which exits when y = 0

code:
Draw.Fill (1, 1, 16, 44)
        Draw.FillOval (xx, yy, 2, 2, 0)
        delay (5)
        View.Update
        Draw.FillOval (xx, yy, 2, 2, 16)


There's a problem with your draw order, for one thing.

You need at least one X and Y variable per thing that moves (hint: arrays are your friend). For example, here's how you move 2 things at once.

code:

var ball1X : int := 10
var ball1Y : int := 10
var ball2X : int := 10
var ball2Y : int := 10

proc Animate
    ball1X += 1 %move ball1 right
    ball2Y += 1 %move ball2 up
    Draw.FillOval (ball1X, ball1Y, 5, 5, blue)
    Draw.FillOval (ball2X, ball2Y, 5, 5, red)
end Animate

loop
    Animate
end loop


This is 2 animations running at the same time. Or, it's 1 complicated animation.

To animate snow, you'll need hundreds of X and Y variables, but that's way too much code to write. Instead, use an array and a for loop.

ohh yea (facepalm) insectoid I did not account for hundreds of snow flakes Razz
