Help with Sprites and Getch

[MichaelM]

Im making a game with a helicopter that'll move around when you press w,a,s,d. In the animation, the sprite moves up and down to give a better helicopter effect
as it bobs up and down. However, I cant figure out how to get it to move like that even when you arent pressing anything. Heres the code, right now it moves left only.

code:

setscreen ("graphics:1024;768") var left1, left2, x : int x := 0 var sprite : int var ch : string (1) left1 := Pic.FileNew ("heli-left1.bmp") left2 := Pic.FileNew ("heli-left2.bmp") sprite := Sprite.New (left1) Sprite.SetPosition (sprite, 100, 100, true) Sprite.SetHeight (sprite, 1) Sprite.Show (sprite) loop     if hasch then         getch (ch)         if ch = "a" then             x := x + 10             delay (500)             Sprite.Animate (sprite, left2, 100 - x, 100, false)             delay (500)             Sprite.Animate (sprite, left1, 100 - x, 102, false)         end if     end if end loop

Could someone please show me how to do this, and were to put it in this code, thanks!

Well the problem is that your entire animation is wrapped in if hasch, so nothing will happen if no keys are pressed.

Normally Input.KeyDown is recommended for handling input. At least take the animation out of the if structure and run it every time, but if no keys are pressed, x will simply remain itself.

thanks, ill try that, but im running Turing 3.1 or something, so Input.KeyDown and stuff might not work, but ill try it out
