Object movement

I have a shooting game and I wan't the target to move not only side ways but also up and down at the same time. Can someone please post the code to do this.

And I was also wondering if there is a code for a pic that moves from left to right but also rotates. If so could you please post it!!

Thanks

I don't want to control the picture. I wan't it to be moving automatically.
ANIMATION!!! (basically)

please reply with the right answer!

thanks

You need to be more specific nate. With what you've described I'd say the same thing. To move side ways and up and down at the same time would be to move diagonally. Or do you mean you want the user to be able to switch axis ie go up then go left.

To get a picture to rotate use the Pic.Rotate command. (works only in Turing v4.x)

Thanks but could you expand more on the Pic.Rotate. The way they explain it in the Turing Reference guide is hard to understand. Do you mind or anyone else mind expanding on the Pic.Rotate . Like how to make a picture move from 1 side of the screen to the other while rotating.

code:


View.Set ("graphics:300;250,nobuttonbar")
        var pic : array 0 .. 35 of int
        var f : int := Font.New ("Serif:36")
        const CTR : int := 57
        Font.Draw ("Hello", 5, 45, f, black)
        Draw.FillOval (CTR, CTR, 3, 3, brightred)
        pic (0) := Pic.New (0, 0, 115, 115)
        cls
        for angle : 1 .. 35
            pic (angle) := Pic.Rotate (pic (0), angle * 10, CTR, CTR)
        end for
       
        var x : int := CTR
        var y : int := CTR
        var dx : int := 1
        var dy : int := 1
        loop
            for angle : 0 .. 35
                Pic.Draw (pic (angle), x  CTR, y  CTR, picCopy)
                if x + dx < CTR or x + dx > maxx  CTR then
                    dx := dx
                end if
                if y + dy < CTR or y + dy > maxy  CTR then
                    dy := dy
                end if
                x += dx
                y += dy
                delay (50)
            end for
        end loop



This makes the word HELLO rotate and move from left to right but I don't understand what they are doing!!

Thanks

there're 2 forloops

1st creates a bunch of pictures rotated at different angles

2nd loop draws different pictures at different locations, making it looks like its moving and rotating.

how do you rotate the pictures easily, sounds little different !

Is it just me, or is every other thread in the Help section Necro'd old threads now?
