Post subject:  Character walking effect for side-scroller
hey
i'm making a side scroller and wondered if anybody could help me out on how to alternate the pics to give a walking effect while using the Input.Keydown method of character control.

thanks for the help

Here it is, you can simplify them with arrays if you want.

code:
var pic1 := Pic.FileNew ("step1.bmp")
var pic2 := Pic.FileNew ("step2.bmp")
var pic3 := Pic.FileNew ("step3.bmp")
var pic4 := Pic.FileNew ("step4.bmp")

var x : int := 50
var step := 1 %What step the player is at
var ch : string(1)
loop
    getch(ch)
    if ch = KEY_RIGHT_ARROW then
        if step = 1 then
            Pic.Draw (pic1, x, 100, picCopy)
         elsif step = 2 then
            Pic.Draw (pic2, x, 100, picCopy)
         elsif step = 3 then
            Pic.Draw (pic3, x, 100, picCopy)
         elsif step = 4 then
            Pic.Draw (pic4, x, 100, picCopy)
         end if
         step := step + 1
         x := x + 10
         if step = 5 then
             step := 1
         end if
    end if
end loop

Thanks for the code but i'm using the Input.KeyDown command and if i use your way the guy just contantly flashes through the steps (because theres no getch) I know theres a way to do it using the Input.KeyDown command so post if you got time and know the way.

thanks

just building on the other code:
code:
var pic1 := Pic.FileNew ("step1.bmp")
var pic2 := Pic.FileNew ("step2.bmp")
var pic3 := Pic.FileNew ("step3.bmp")
var pic4 := Pic.FileNew ("step4.bmp")

var x : int := 50
var step := 1 %What step the player is at
var ch : array char of boolean
loop
    Input.KeyDown (ch)
    if ch (KEY_RIGHT_ARROW) then
        if step = 1 then
            Pic.Draw (pic1, x, 100, picCopy)
         elsif step = 2 then
            Pic.Draw (pic2, x, 100, picCopy)
         elsif step = 3 then
            Pic.Draw (pic3, x, 100, picCopy)
         elsif step = 4 then
            Pic.Draw (pic4, x, 100, picCopy)
         end if
         step := step + 1
         x := x + 10
         if step = 5 then
             step := 1
         end if
    end if
end loop


basically the same thing, just change to input.keydown

oh man. lol according to the turing manual, GIFs should be in Turing, which would render most of this useless.

according to the turing manual, sprites work and its the best language and that tom west is a genius

according to the turing manual, it's a party!

but ya if GIF works in turing, i'd be awsome cause then you can import animated pics

lol true, if you complain to him about how crap turing is he doesn't reply, but if you report a bug he replys right away asking how he can recreate the bug

probably because it is more important to make what you have now working entirely than making turing better as a whole as you seem so bent on doing... really turing isn't meant to make retail programs or anything, just for learning. if you want a better language, learn something like C++ or Java. but please stop whining about how bad turing is or whatever it is you think is wrong with it. it does what it was created to do just fine.

i guess. okay paddy. challenge accepted.

wha? what challange? what's going on? is it me or is anyone else confused?

the challenge to get out of the turing 'rut' and move on.

it's not that I'm challenging you to stop using turing, just asking you (not necesarily you Jay Lo, but people in general..) to stop whining about it

ya, but you're right. i'm so addicted to turing syntax...

lol ya i wrote so many compsci tests, i for got how to write the multiplication sign, i keep on writing astricks on my science tests
Author:  PaddyLong [ Wed Jun 18, 2003 6:17 pm ]
Post subject: 
I just use a dot for when I'm writing multiplication... x's can get confusing when you're working with variable x
Author:  Andy [ Wed Jun 18, 2003 6:18 pm ]
Post subject: 
but its sceince, not math, and science teachers like to use X and plus there are plenty of other variables to use
Author:  PaddyLong [ Wed Jun 18, 2003 6:23 pm ]
Post subject: 
x is a pretty standard one, especially when talking about graphs
Author:  JayLo [ Wed Jun 18, 2003 6:24 pm ]
Post subject: 
x, y, a, b
that's all i ever hope to use.

what about theta and alpha for angles?

and z, i, j, k for vectors and 3 space
Author:  Andy [ Wed Jun 18, 2003 6:35 pm ]
Post subject: 
3 spaces wha?
Author:  PaddyLong [ Wed Jun 18, 2003 6:38 pm ]
Post subject: 
3d plane, x, y, z (you're probably used to 2 space, x, y)
i, j, k are unit vectors for planes x,y,z respectively... in algeo you don't look at points in a plane as just points, you look at them as vectors...
so like point (x, y, z) is actually a linear combination of vectors i, j, k so it is actually vector OP = xi + yj + zk

o u know i'm not a moron, i didn't know what u meant about 3 spaces, i thought u were talking about " "

Post subject: 
isnt that just one space? three spaces is more like this: " "

Post subject: 
lol, html doesn't display extra spaces unless you use & nbsp; "   "
