Animating Characters

[Tasty Pastry]

I'm trying to animate some characters in turing, but I don't know how to animate then only when a key is pressed. For example goes up when the up arrow key is pressed, down when the down arrow key is pressed, etc. I also can't figure out how to stop the character from moving after the key has been depressed. I've got the animation part down, but the rest I can't seem to figure out.

Turing:

var numFrames := Pic.Frames ("Guy Walking-Fight-Dead (3).gif")         % Load the picture         var delayTime : int         var pics : array 1 .. numFrames of int         Pic.FileNewFrames ("Guy Walking-Fight-Dead (3).gif", pics, delayTime)         var sprite: int         sprite:= Sprite.New (pics (1))         Sprite.SetPosition (sprite, 0, 100, false)         Sprite.Show (sprite)         for x : 2 .. maxx by 2             Sprite.Animate (sprite, pics ((x div 2) mod numFrames + 1), 100, x, false)             delay (60)    % Stop sprite from moving too quickly         end for         Sprite.Free (sprite)

Let me see if I understand what you're going for here.

if a key is pressed, then move the character.

Does that sound about right?

Yeah, I did try if statements, but if I put them inside the for loop, the for loop just executes and finishes without key input, and if I put it before the loop, it does work, but it goes through the whole animation sequence instead of stopping after the key is depressed.

Turing:

% If statement after for var chars : array char of boolean var numFrames := Pic.Frames ("Guy Walking-Fight-Dead (3).gif")         % Load the picture         var delayTime : int         var pics : array 1 .. numFrames of int         Pic.FileNewFrames ("Guy Walking-Fight-Dead (3).gif", pics, delayTime)         var sprite: int         sprite:= Sprite.New (pics (1))         Sprite.SetPosition (sprite, 0, 100, false)         Sprite.Show (sprite)         for x : 2 .. maxx by 2         Input.KeyDown (chars)             if chars (KEY_UP_ARROW) then             Sprite.Animate (sprite, pics ((x div 2) mod numFrames + 1), 100, x, false)             delay (60)    % Stop sprite from moving too quickly             end if         end for         Sprite.Free (sprite) % If statement before for var chars : array char of boolean var numFrames := Pic.Frames ("Guy Walking-Fight-Dead (3).gif")         % Load the picture         var delayTime : int         var pics : array 1 .. numFrames of int         Pic.FileNewFrames ("Guy Walking-Fight-Dead (3).gif", pics, delayTime)         var sprite: int         sprite:= Sprite.New (pics (1))         Sprite.SetPosition (sprite, 0, 100, false)         Sprite.Show (sprite)         loop         Input.KeyDown (chars)         if chars (KEY_UP_ARROW) then         for x : 2 .. maxx by 2                   Sprite.Animate (sprite, pics ((x div 2) mod numFrames + 1), 100, x, false)             delay (60)    % Stop sprite from moving too quickly               end for         end if         end loop         Sprite.Free (sprite)

Why do you think you need a for loop?

Because in the animation sequence there are different sprites to use, so I needed that so it can go through all the sprites in the walking animation.

Are you sure you can't think of another way to do that without a for loop?

You only need the for loop so there's a counter for the gif frames, right? Can you think of another way to make a counter? I mean, it is just a number that increments every loop after all.
